The spherical silica powder in sunscreen, known as nanospherical silica, is manufactured through an innovative process and has a narrow particle size distribution and a large surface area. The properties of nanospherical silica such as absorbency, smoothness, and suspension and redispersibility make spherical silica powder useful in sunscreens.
As an indispensable part of people's daily lives, cosmetics can not only make people more beautiful but also protect the skin from ultraviolet damage to a large extent. As an essential component of cosmetics, sunscreen ingredients have always attracted much attention. This article will delve into the development and application of cosmetic sunscreen ingredients and lead readers to understand the latest developments in this field.
Classification of cosmetic sunscreen ingredients
Cosmetic sunscreen ingredients can be divided into two categories: physical sunscreen ingredients and chemical sunscreen ingredients. Physical sunscreen ingredients include dioxide and zinc oxide, which are very good at blocking UV rays but often cause white spots and a greasy feeling when used. Chemical sunscreen ingredients, such as benzoic acids, benzophenones, etc., resist UV damage by absorbing and converting UV energy.
R&D and innovation of cosmetic sunscreen ingredients
As people pay more and more attention to skin protection, the research development and innovation of cosmetic sunscreen ingredients have become particularly important. Scientists are constantly seeking new materials and technologies to improve the effectiveness and quality of sunscreen products. In recent years, nanotechnology has been widely used in the field of sunscreen. Through the use of nanoparticles, the transparency and smooth feel of physical sunscreen ingredients can be improved, and the greasiness can be reduced.
In addition, more and more research is focused on improving the stability and safety of chemical sunscreen ingredients. Since some chemical sunscreen ingredients may produce sensitizing or harmful substances, scientists use auxiliary technologies such as synthetic fluorescent agents to solve this problem when developing new ingredients.
Application fields of cosmetic sunscreen ingredients
Cosmetic sunscreen ingredients are widely used in various daily skin care products, such as sunscreen, day cream, foundation, etc. Their function is to protect the skin from ultraviolet damage by blocking, absorbing, and converting ultraviolet energy, thereby preventing sun spots, wrinkles, and even skin cancer.
In addition, cosmetic sunscreen ingredients are often used in outdoor sporting goods, textiles, and other fields. For example, adding sunscreen ingredients to sportswear can effectively prevent ultraviolet rays from penetrating and protect people's skin health during outdoor sports.
Standards and supervision of cosmetic sunscreen ingredients
In order to ensure the safety and quality of cosmetic sunscreen ingredients, various countries have formulated corresponding standards and regulatory measures. For example, the European Union has strict regulations on the ingredients used in sunscreen products, clarifying which ingredients can be used and the upper limit of dosage. The United States has established FDA (U.S. Food and Drug Administration) standards, which require strict safety assessment and effectiveness testing before approving sunscreen products.
In addition, in response to consumer demands and concerns, many companies have also promised not to use chemical sunscreen ingredients that are harmful to the human body and have launched chemical-free sunscreen products to meet the demand for natural and gentle products.
Development Trends of Cosmetic Sunscreen Ingredients
In the future, the development of cosmetic sunscreen ingredients will be more efficient and safer. With the advancement of biotechnology, people can expect more use of naturally derived sunscreen ingredients, such as those extracted from plants, to achieve better sunscreen effects.
In addition, since prolonged exposure to the sun may cause vitamin D deficiency, some scientists and companies are also studying how to ensure adequate vitamin D synthesis while protecting the skin.
Application of silica powder in sunscreen cosmetics
The application of silica powder in sunscreen cosmetics is mainly reflected in its unique physical and chemical properties. The original composite structure of silica powder includes smooth silicone microspheres grafted and coated with soft and elastic silicone rubber microspheres, giving it a soft and smooth touch like air. This characteristic allows silica powder to provide a drier and smoother application experience in sunscreen cosmetics.
In addition, silicone powder can absorb silicone oil and has oil control properties, thickening properties, and soft light effects. For example, silicone powder products such as KSP-100, KSP-101, and KSP-105 can absorb silicone oil (about 1 to 2 times its weight) and help control oil secretion on the skin's surface. This thickening property and softening effect also allow sunscreen cosmetics to maintain their texture and color after use better, improving product stability.
Another essential feature of silica powder is that it is easily dispersed in water, which allows it to be mixed better with other ingredients in sunscreen cosmetics and improves the uniformity and stability of the product. At the same time, this characteristic also allows silica powder to provide a drier and smoother experience in products such as water creams.
