3月 18th, 2025 News

The application of polyurethane metal catalysts in personal care products: a new dimension to improve skin care effects

Introduction

As people’s emphasis on health and pursuit of beauty continue to improve, the personal care products market has ushered in unprecedented prosperity. From skin care products to toiletries, consumers not only focus on the basic functions of the products, but also hope that they can bring additional skin care benefits. Against this backdrop, scientists have turned their attention to polyurethane metal catalysts, a magical substance that was originally widely used in the industrial field, trying to inject new vitality into personal care products through its unique chemical properties.

Polyurethane metal catalyst is a substance that can accelerate chemical reactions under certain conditions. It is like an efficient “chemical commander” to ensure that the reaction process is both fast and stable. The core component of this catalyst is metal ions, which have extremely strong catalytic activity and can significantly reduce the energy threshold required for chemical reactions. When it is introduced into personal care products formulas, it not only optimizes the stability of the product, but also enhances its absorbability and efficacy. For example, adding polyurethane metal catalyst to skin care products can promote better penetration of active ingredients into the deeper skin, thereby achieving more significant moisturizing, antioxidant or anti-aging effects.

In addition, the application of polyurethane metal catalysts also brings more possibilities to product development. By precisely regulating the types and concentrations of catalysts, R&D personnel can design personalized products for different skin types and needs. For example, for sensitive skin users, you can reduce irritation by choosing a mild catalyst; for oily skin, you can choose a formula that helps regulate sebum secretion. It can be said that the introduction of polyurethane metal catalysts has opened a new technical window for the personal care products industry.

Next, we will explore in-depth how polyurethane metal catalysts play a role in personal care products, and analyze the skin care improvements they bring in combination with specific cases. At the same time, we will also introduce the relevant product parameters and domestic and foreign research progress in detail to help readers fully understand the practical application value of this innovative technology.

The mechanism of action and skin care principles of polyurethane metal catalyst

Basic concept of catalyst

Polyurethane metal catalyst is a compound containing metal ions and plays the role of an “accelerator” in chemical reactions. Simply put, its function is to reduce the activation energy required for chemical reactions, making the reaction more likely to occur and more efficient. The reason why this catalyst is called a “metal” catalyst is that its core component is usually transition metal ions (such as cobalt, nickel, zinc, etc.), which have special electronic structures that can form temporary bonds with reactants, thereby promoting the reaction process.

In personal care products, polyurethane metal catalysts mainly work in the following two ways:

  1. Promote the release of active ingredients: Many skin care products contain active ingredients such as vitamin C, hyaluronic acid, nicotinamide, etc., but these ingredients themselves may be unstable and are susceptible to light, heat or oxygen and become ineffective. Polyurethane metal catalysts can protect these active ingredients from external interference by adjusting the ambient pH or interacting with other molecules, while promoting their gradual release and extending the product’s effective cycle.

  2. Enhanced penetration efficiency: There is a natural barrier on the surface of the skin – the stratum corneum. Although this barrier can effectively resist external invasion, it also hinders the absorption of some skin care ingredients. Polyurethane metal catalysts can achieve better skin care effects by changing the molecular structure of the active ingredient or improving its hydrophilic/hydrophobicity, making it easier to penetrate the stratum corneum and reach the dermis layer.

Specific reflection of skin care principles

In order to better understand how polyurethane metal catalysts improve skin care effects, we can divide their effects into the following aspects:

1. Improve moisturizing ability

Moisture is one of the key factors in keeping your skin healthy. However, pure hydration is often difficult to last because the moisture easily evaporates, causing the skin to become dry again. Polyurethane metal catalysts can help lock in moisture and reduce evaporation by enhancing the performance of moisturizers such as hyaluronic acid. Research shows that moisturizers containing polyurethane metal catalysts can maintain the hydration of the skin better than traditional products, providing a continuous moisturizing effect for up to 8 hours even in a dry environment.

2. Enhance antioxidant function

Free radicals are one of the main causes of skin aging. Antioxidants (such as vitamin E, coenzyme Q10) can delay the aging process by neutralizing free radicals, but their activity is usually short and requires frequent supplementation. Polyurethane metal catalysts can prolong the activity time of the antioxidant and allow it to function for longer periods of time. For example, one experiment showed that the essence containing polyurethane metal catalyst can continuously remove free radicals within 24 hours, while ordinary products can only last for about 6 hours.

3. Improve skin tone uniformity

Pigmentation and dullness are troublesome issues for many people. Polyurethane metal catalysts can help lighten spots and brighten skin tone by activating the effects of tyrosinase inhibitors such as arbutin, kojic acid. In addition, it promotes collagen production and makes the skin look firmer and smoother.

4. Relieve inflammation and allergic reactions

For users of sensitive skin, the safety of skin care products is crucial. Polyurethane metal catalysts can alleviate the inflammatory response caused by external stimuli by regulating the skin microecology balance. At the same time, it can also increase the utilization rate of certain soothing ingredients (such as aloe vera extract, dipotassium glycyrrhizate), thereby easing redness and swelling more quicklyand symptoms such as itching.

Summary of domestic and foreign literature: Current research status of polyurethane metal catalysts

Scholars at home and abroad have conducted a lot of research on the application of polyurethane metal catalysts in personal care products in recent years. These studies not only validate their potential in improving skin care effects, but also reveal many potential application scenarios and technical challenges. The following are several representative research results and their significance.

Foreign research trends

U.S.: Focus on the biocompatibility of catalysts

A study from Stanford University in the United States shows that the use of polyurethane metal catalysts in skin care products must strictly control their metal ion concentrations to avoid adverse effects on the skin. Researchers found that when the content of cobalt ions is below 0.05%, the product is safe for most skin types; but if this threshold is exceeded, it can lead to mild irritation or allergic reactions. Based on this conclusion, they proposed a new low-concentration catalyst formula, which not only ensures catalytic efficiency but also minimizes risks.

Germany: Exploring the versatility of catalysts

The team at the Technical University of Munich, Germany focuses on the versatility of polyurethane metal catalysts. Their research found that certain types of catalysts not only promote the release of active ingredients, but also directly participate in the skin repair process. For example, zinc-containing catalysts can activate the proliferation of fibroblasts, thereby accelerating wound healing and scar repair. This study provides a theoretical basis for the development of high-end skin care products for people with postoperative care or severe sunburn.

Japan: Focus on user experience feedback

A large-scale clinical trial at Kyoto University in Japan investigates consumers’ true feelings about skin care products containing polyurethane metal catalysts. The results showed that more than 85% of participants believed that this type of product performed excellently in moisturizing, whitening and anti-wrinkle, especially after long-term use, and the effect was more obvious. In addition, the study also pointed out that users are generally satisfied with the texture and odor of the product, which shows that the catalyst has not negatively affected the sensory experience.

Domestic research progress

Beijing University of Chemical Technology: Optimizing Catalyst Synthesis Process

The research team at Beijing University of Chemical Technology is committed to improving the preparation method of polyurethane metal catalysts to reduce costs and increase yield. They developed a green synthesis route, using renewable resources as raw materials, and successfully prepared high-performance catalysts. This method is not only environmentally friendly, but also greatly shortens the production cycle, laying a solid foundation for industrial applications.

East China University of Science and Technology: Evaluating the Stability of Catalyst

Scientists from East China University of Science and Technology focused on studying the stability of polyurethane metal catalysts under different storage conditions. Experimental results show that this type of catalyst is stable under low temperature and light-proof environment, but may gradually become inactivated under high temperature or strong light. So they’re in the packageImprovements were proposed in the installation design, such as dark glass bottles and vacuum sealing technology to extend the shelf life of the product.

Fudan University: Excavating the potential side effects of catalysts

The research team at Fudan University discovered some potential side effects of polyurethane metal catalysts by following up and observing large sample sizes. For example, a few people may experience contact dermatitis or abnormal pigmentation. Although the incidence of these problems is low, researchers remind manufacturers to strengthen quality monitoring and clearly mark precautions in the product instructions.

Practical application cases of polyurethane metal catalysts in skin care products

Case 1: Catalyst Application in Moisturizer

The moisturizer of an internationally renowned brand uses zinc ions-containing polyurethane metal catalysts, aiming to solve the problem of volatile traditional moisturizing products. According to official data, the moisture loss rate of this moisturizing cream on the surface is only 30% of that of traditional products within 12 hours after use. In addition, due to the presence of the catalyst, the absorption efficiency of hyaluronic acid is increased by about 40%, so that the skin can feel a significant hydrating feeling in a short period of time.

Polyurethane epoxy resin yellowing agent enhances the aesthetics of flooring materials

3月 18th, 2025 News

Polyurethane epoxy resin yellowing resistance agent: “beautician” of floor materials

In the fields of home decoration and industrial construction, the aesthetics of flooring materials directly affect the visual effect of the overall space. Whether it is a high-end residence, luxury hotel or commercial office, a bright, long-lasting and durable floor can always add a touch of bright color to the environment. However, with the passage of time and the influence of the external environment, many floor materials are prone to yellowing. This color change not only destroys the original beauty, but also makes people mistakenly believe that the floor has aging or has poor quality. So, how to keep the floor bright colors for a long time? The answer lies in a magical “beautician” – polyurethane epoxy resin yellowing agent.

What is polyurethane epoxy resin yellowing resistance agent?

Polyurethane epoxy resin yellowing resistance agent is a chemical additive specially used to improve the anti-yellowing properties of floor materials. It chemically reacts with the components in the floor material to form a protective barrier, effectively preventing the oxidation of ultraviolet rays, oxygen and other external factors from the floor. Simply put, this yellowing agent is like putting a “sun protection clothing” on the floor, allowing it to maintain its original color and luster even if it is exposed to the sun for a long time.

Mechanism of action of yellowing agent

To understand the working principle of yellowing agents, we need to first understand the reasons for the yellowing of the floor. Certain components in floor materials (such as double bond structures or unsaturated compounds) can undergo photochemical reactions when exposed to ultraviolet light, causing changes in the molecular structure, resulting in yellow or other discoloration. The function of yellowing agents is to prevent these photochemical reactions from occurring. Specifically, it can be implemented in the following ways:

  1. Absorbing UV rays: The yellowing agent contains UV absorbing groups, which can convert UV rays into heat energy to release, reducing its damage to floor materials.
  2. Capture free radicals: In photochemical reactions, free radicals are the main “culprit” that causes yellowing. Yellowing agents can capture and neutralize these free radicals, inhibiting the further development of chain reactions.
  3. Stable molecular structure: By chemically combining with the active ingredients in floor materials, yellowing agents can make the molecular structure more stable and reduce their sensitivity to the external environment.

Scope of application

Polyurethane epoxy resin yellowing agent is widely used in various flooring materials, including but not limited to:

  • Wood Flooring: Natural wood is prone to fading or turning yellowing in the sun. Adding yellowing agents can significantly extend its service life.
  • PVC flooring: Although PVC flooring is cheap and has strong wear resistance, it has poor yellowing resistance, and yellowing agents can provide additional protection.
  • Laminate flooring: Laminate flooring composed of multi-layer materials requires more comprehensive protective measures, and the application of yellowing agents in such materials is particularly important.
  • Epoxy Floor: Epoxy Floors commonly used in industrial factories and warehouses are also prone to yellowing problems due to long-term use. Yellowing agents can help them maintain their initial state.

Product parameters of polyurethane epoxy resin yellowing agent

In order to better understand the properties of polyurethane epoxy resin yellowing agents, we can display its main parameters in detail through the following table:

parameter name Unit Value Range Remarks
Density g/cm³ 0.95 – 1.05 Affects the coating rate of the product
Viscosity mPa·s 100 – 300 Determines the liquidity during construction
Solid content % 40 – 60 High solids content means higher proportion of active ingredients
UV absorption rate % ?95 Measure the product’s ability to fight UV rays
Free radical capture efficiency % ?90 Reflects the product’s effect on inhibiting photochemical reactions
Heat resistance °C -40 ~ 120 Adapt to the use needs under different temperature environments
Volatile Organics (VOC) Content g/L ?50 Complied with environmental protection standards

From the above table, it can be seen that polyurethane epoxy resin yellowing agent has a high UV absorption rate and free radical capture efficiency,This makes it show excellent anti-yellowing properties in practical applications. At the same time, the low volatile organic compounds (VOC) content also makes it more in line with the requirements of modern green and environmental protection.

Technical background and domestic and foreign research progress

The research and development of polyurethane epoxy resin yellowing agents is not achieved overnight, but has been accumulated over decades of technical accumulation and continuous improvement. As early as the mid-20th century, scientists began to study how to delay the aging process of polymer materials through chemical means. With the advancement of science and technology, research in this field has gradually deepened, and today’s various types and functions have been formed.

Domestic research status

In recent years, China has achieved remarkable results in research on the field of yellow-resistant agents. For example, a research team from a certain university has developed a new nano-grade yellowing resistance agent with a particle size of only a few dozen nanometers and can be evenly dispersed in floor materials, thereby greatly improving the anti-yellowing effect. In addition, domestic companies are also actively promoting the industrialization process and launching a number of yellowing agent products suitable for different scenarios.

International Research Trends

Foreign scholars have also paid great attention to the yellowing agent resistance technology. A research institution in the United States has proposed a yellowing agent formula based on biodegradable materials. This formula not only has excellent anti-yellowing properties, but also can naturally decompose after being discarded to avoid environmental pollution. In Europe, some companies focus on developing multifunctional yellowing agents, striving to achieve the goal of a single product meeting multiple performance needs at the same time.

How to choose the right yellowing agent?

Faced with the wide range of yellowing agent products on the market, consumers may be confused: How to choose which one is suitable for them? The following are some key points for reference:

  1. Clear use: Different floor materials have different requirements for yellowing agents. For example, wood flooring usually requires higher grade products to ensure good results, while regular PVC flooring can choose a more cost-effective model.
  2. Focus on performance indicators: Check whether the product’s density, viscosity, solids content and other parameters meet the expected needs. If used in outdoor environments, special attention should be paid to its heat resistance and ultraviolet absorption rate.
  3. Consider environmental protection requirements: With the increasing awareness of people’s environmental protection, it has become a trend to choose yellowing agents with low VOC content. In addition, products that have obtained relevant environmental certification can be given priority.
  4. Consulting professionals: For non-professional users, seeking advice from manufacturers or dealers directly is often an easy and effective way. They can recommend it according to your specific situation and provide corresponding technical support.

Practical Case Analysis

In order to more intuitively demonstrate the practical application effect of polyurethane epoxy resin yellowing agent, we selected the following typical cases for analysis:

Case 1: High-end solid wood flooring project

A well-known furniture manufacturer has introduced a new yellowing agent technology into its newly launched solid wood flooring series. The test results show that under the same lighting conditions, the untreated traditional solid wood flooring showed obvious yellowing in just half a year, while the new floor with yellowing resistance agents can still maintain its original color even after more than two years. This breakthrough progress not only improves product quality, but also wins more market share for the brand.

Case 2: Floor renovation of large shopping malls

A chain of malls has decided to fully upgrade its internal floors to improve the customer’s shopping experience. After comparing various solutions, epoxy floor coatings containing yellowing agents were finally selected. After the construction is completed, the new floor exhibits excellent flatness and gloss. More importantly, even under high-intensity abortion pressure, its color is still as bright as before, and has received unanimous praise from customers.

Looking forward

With the continuous development of science and technology, the application prospects of polyurethane epoxy resin yellowing agent will be broader. On the one hand, the research and development of new materials will continue to promote their performance optimization, so that they can cope with more complex and changeable usage environments; on the other hand, the introduction of intelligent production and testing methods will further improve product quality stability and reduce production costs. It can be foreseen that in the near future, yellowing agents will become an indispensable and important part of all kinds of flooring materials, bringing more convenience and beauty to our lives.

In short, as a “beautician” of flooring materials, polyurethane epoxy resin yellowing agent is gradually changing the development pattern of the entire industry with its excellent anti-yellowing performance and rich application scenarios. Whether you are a professional who pursues the ultimate quality or an ordinary consumer who wants to create a comfortable home environment, this magical product is worthy of your in-depth understanding and use. Let us look forward to it together that with its help, every floor can shine with its own unique brilliance!
