In the dynamic world of cosmetic and skincare formulation, the need for high-performance, environmentally friendly ingredients is more significant than ever. According to a recent Grand View Research report, the global cosmetics market size was estimated at USD 295.95 billion in 2023 and is expected to grow at a CAGR of 6.1% from 2024 to 2030; this means it will be worth approximately USD 450.27 billion in 2030. Consumers increasingly demand high-performance, sustainable ingredients in their skincare and cosmetic products.

AGC Chemicals Europe (AGCCE) addresses this demand with its RESIFA™ Cosmetics line, featuring SUNSPHERE fine silica microspheres. These innovative amorphous microspherical silica gels enhance product performance across various applications, from skincare to industrial uses, providing formulators with versatile and sustainable solutions.

The Advantages of Silica Microspheres

RESIFA™ silica microspheres, known for their perfectly spherical shape and amorphous structure, come in a size range of 3 to 20 micrometres. These environmentally safe particles are derived from natural materials and are free from plastic particles, making them an eco-friendly choice. Certified by ECOcert, COSMOS, Halal, and Kosher standards, these microspheres are produced in Japan and are accessible worldwide.

Key Benefits in Cosmetic and Skincare Formulations

Enhanced Texture and Spreadability

The spherical shape and fine size of the RESIFA™ microspheres significantly improve the feel and texture of cosmetic formulations. They create a silky-smooth texture that enhances spreadability, making products more pleasant to apply. This attribute is particularly valuable in makeup foundations and tinted moisturisers, where a smooth, even application is crucial.

Oil and Perspiration Absorption

These RESIFA™ microspheres absorb excess oil and perspiration, addressing common concerns such as greasiness and shine. This makes them ideal for formulations for oily skin types or products that withstand humid conditions. Controlling oil production helps maintain a matte finish throughout the day, enhancing the skin’s overall appearance.

SPF Boost and UV Protection

In sun care formulations, RESIFA™ silica microspheres play a vital role by providing an SPF boost to both organic and inorganic UV actives. This enhancement improves sunscreens’ protective capabilities and ensures the formulations remain lightweight and non-greasy, a significant advancement over traditional sun care products.

Soft Focus and Mattifying Effects

The unique light-scattering properties of RESIFA™ microspheres impart a soft-focus effect that blurs imperfections such as wrinkles and blemishes. This mattifying effect is highly desirable in cosmetics, creating a smooth, flawless finish. Products like facial cleansers and exfoliating body scrubs benefit from this attribute by leaving the skin refreshed and rejuvenated.

Versatility Across Applications

RESIFA™ microspheres are suitable for various formulations, including oil-in-water, water-in-oil, and anhydrous systems. They can encapsulate oils to form powders and gels, allowing formulators to create innovative textures and delivery systems. This versatility makes them a valuable addition to various cosmetic and skincare products, from lipsticks and mascaras to facial cleansers and body scrubs.

Spotlight on RESIFA™ SOLESPHERE™ Series

H-Series

The RESIFA™ SUNSPHERE™ H-Series offers synthetic spherical silica with low cohesiveness and high fluidity. The H-Series caters to different formulation needs and is available in both standard and high oil absorption types. The high oil absorption type has over twice the absorption capacity of the standard type, making it exceptionally bulky and easy to disperse.

NP-Series

The RESIFA™ SUNSPHERE™ NP-Series features non-porous, heat-treated silica particles known for their high hardness. These particles make excellent fillers for increasing resin hardness. They offer transparency when added to resins and films, providing superb heat resistance and dimensional stability across various temperatures.

L-Series

The RESIFA™ SUNSPHERE™ L-Series is characterised by synthetic spherical silica with low cohesiveness and high fluidity, offering better slipperiness and spreadability. Despite its lower specific surface area, the L-Series maintains high oil absorption capacity, making it suitable for chemical surface modification or coating. Its light scattering effect benefits cosmetics, serving as a matting agent for coatings.

Environmental and Economic Impact

As the cosmetics industry prioritises sustainability, the use of RESIFA™ silica microspheres offers a viable solution to replace microplastics and other environmentally harmful ingredients. Their natural, biodegradable nature ensures they do not contribute to plastic pollution, making them a responsible choice for eco-conscious brands and consumers.

Moreover, the cost-effectiveness of these microspheres as binders and fillers contributes to more economical formulations without compromising performance. This balance of cost and quality is essential for manufacturers producing high-performance products at competitive prices.

Beyond Cosmetics: Diverse Applications

While RESIFA™ microspheres excel in cosmetic and skincare formulations, their applications extend beyond these areas. They enhance chromatography columns, increase the strength of 3D printing resins, and serve as catalyst supports for polyolefin polymerisation. Additionally, they play a crucial role in synthesising organic compounds, demonstrating their versatility and broad utility in various scientific and industrial fields.

Conclusion

AGC Chemicals Europe’s RESIFA™ fine silica microspheres represent a significant advancement in the formulation of cosmetic and skincare products. Their unique properties, ranging from enhancing texture and spreadability to providing oil absorption and UV protection, make them an invaluable ingredient for modern formulations. Coupled with their environmentally safe profile and cost-effectiveness, these microspheres meet the demands of a dynamic market, paving the way for innovative and sustainable product development.
