PRODUCT DETAILS

1.1 Basic definitions
Spherical silica for cosmetics is a specially processed cosmetic-grade functional additive in the form of white ultra-fine spherical powder. Its core features include a spherical structure and controlled particle size distribution, providing excellent skin texture modulation, light scattering, and carrier functions for active ingredients. It does not react with cosmetic bases or skincare actives like Vitamin C and hyaluronic acid, making it a key ingredient for enhancing skin feel and functionality in mid-to-high-end products such as foundation, loose powder, and essence.

1.2 Core values
As a key ingredient in cosmetics for "dual optimization of skin texture and makeup effect", spherical cosmetic-grade silica effectively addresses industry pain points of traditional non-spherical powders (such as talc and regular silica), including rough skin texture, heavy makeup appearance, and dust caking. Through precise control of sphericity and particle size, it delivers a dual experience of "smooth texture + lightweight finish". The smooth surface characteristics reduce skin friction while porous configurations ensure stable delivery of active ingredients. This provides safe and high-quality functional solutions for premium cosmetics and therapeutic skincare products.

Product Characteristics

2.1 Structural and performance advantages
•High roundness spherical structure: the spherical degree is more than 95%, the surface is smooth and no edge, the particle size can be precisely controlled, and it forms "rolling friction" when applied, with a silky and delicate skin feel without roughness.
•Excellent light scattering performance: the spherical structure can scatter visible light uniformly, and the balance between shading force and transparency is excellent. After adding, it can modify pores and fine lines, so that the makeup surface presents a natural "foggy gloss"; the nano model can improve the transparency of skin care products without affecting the appearance of products.
•Efficient efficacy carrier function: The surface and internal pores of the porous spherical model can stably load whitening, anti-aging and other efficacy components, with a loading rate of more than 85%, and realize 24-hour slow release, improve the utilization rate of components, and reduce the oxidation and inactivation of active ingredients.
•Strong dispersion stability: The surface is modified with silane coupling agent, and the oil/hydrophilic characteristics can be adjusted as needed. It can be dispersed uniformly in the oil phase matrix of cosmetics and the aqueous phase system of skin care products without agglomeration. After storage for 6 months, the particle size distribution deviation is less than or equal to 5%, ensuring product stability.

Application fields

4.1 Cosmetic products
•Foundation / BB cream: It can improve the fluidity of products, and is smooth and easy to spread when applied. At the same time, it can modify pores and fine lines through light scattering. The makeup is light and thin without heaviness, and the makeup time can be extended for 3-4 hours without powder sticking or floating.
•Dust / Honey powder: It can improve the fluffiness of the dust, give a delicate touch when applying makeup, and has excellent oil absorption and control performance. It can reduce facial oil by 60% within 2 hours and keep the makeup fresh and foggy.
•Blush / Eyeshadow: It can optimize the compactness and color rendering of powder, avoid powder flying, and improve the uniformity of color. The color is natural after makeup and it is not easy to remove makeup.
 

4.2 Skincare products
•Essence / Cream: It can improve the skin feel of products, absorb quickly after application, not sticky, and reduce skin friction. It is suitable for sensitive skin anti-aging and whitening products, and there is no risk of irritation.
•Sunscreen: It can disperse sunscreen particles to improve the uniformity of sun protection and reduce whitening phenomenon, while assisting sun protection through light scattering, and the SPF value can be increased by 10-15%.
•Efficacy mask: can carry nicotinamide, retinol and other ingredients, the loading rate is more than 85%, the active ingredients are released slowly when the mask is applied, the penetration efficiency of active ingredients is increased by 30%, and the skin whitening/anti-aging effect is more significant after use.

Recommended dosage

Product Advantages

•Excellent skin feeling experience: the high roundness spherical structure brings silky touch, solves the problems of rough and sticky traditional powder, and improves user satisfaction.
•Multiple functional scenarios: covering makeup skin texture optimization, skin care product absorption promotion, functional ingredient carrier and other scenarios, suitable for the development of all categories of high-end cosmetics.
•High safety compatibility: ultra-fine particle size and mild characteristics, sensitive skin and eye irritation tests, suitable for all kinds of skin, including pregnant women, sensitive muscle people.
•Strong customization capability: particle size (0.1-20μm), sphericity (94-96%) and hydrophobicity can be adjusted as needed, and customized formula solutions can be provided to support differentiated product development of customers.

Frequently asked questions

1. Q: What is the core role of adding silica to cosmetics?
A: It mainly plays a role in filling, controlling oil and thickening. At the same time, it can improve the skin feel of foundation, loose powder and other products, so that the makeup is more smooth and delicate.
2. Q: Is silica safe for skin in cosmetics?
A: Safe. Products that meet the standards of cosmetic raw materials are mild, non-irritating and will not damage the skin in normal use.
3. Q: Can sensitive skin use cosmetics containing silica?
A: Yes. Its ingredients are stable and not easy to cause allergies, most sensitive muscles are suitable for use, it is recommended to try a small area first to confirm.
4. Q: Does it conflict with other ingredients in cosmetics?
A: No. Silica is compatible and can work together to stabilize the formula without affecting the active ingredients (such as moisturizing, whitening ingredients).
5. Q: Where is silica commonly found in cosmetics?
A: It is used in most powdered or cream cosmetics such as loose powder, honey powder, foundation, eyeshadow, lipstick and sunscreen.
