Cosmetic grade silicone resin is a new type of highly cross-linked organopolysiloxane, which is composed of Si-O-Si main chain and organic functional substituents connected to silicon atoms. The cross-linked structure is cage-shaped, dendritic, branched or ladder-shaped. The following is a detailed introduction to cosmetic grade silicone resin:
I. Product characteristics
Film-forming property: Cosmetic grade silicone resin has good film-forming property and can form a uniform and durable film on the skin surface.
Adhesion: The resin has strong adhesion and can firmly adhere to the skin surface and is not easy to fall off.
Hydrophobicity: Silicone resin has excellent hydrophobicity, which can effectively prevent moisture from eroding cosmetics and improve the waterproof performance of the product.
Physiological inertness: The resin has no irritation to the skin and no allergic reaction, and is suitable for all skin types.
Anti-ultraviolet radiation: Silicone resin has a certain ability to resist ultraviolet radiation and can protect the skin from ultraviolet damage.
2. Application fields
Due to its unique properties, cosmetic-grade silicone resins are widely used in the cosmetics field:
Base makeup products: such as foundation, concealer, etc., silicone resins can provide good adhesion, concealer effect and waterproof performance.
Lip makeup products: such as lipstick, lipstick, etc., silicone resins can improve the durability, glossiness and durability of products, while reducing lip lines and making lips fuller.
Eye makeup products: such as eye shadow, mascara, etc., silicone resins can enhance the adhesion and durability of products, making eye shadow less likely to fall off or fade, and mascara more dense and curled.
Sunscreen products: silicone resins can be used as ingredients in sunscreen products to provide good UV shielding and waterproof properties.
Hair care products: such as conditioners, hair masks, etc., silicone resins can provide smooth, shiny and lasting hair care effects.
3. Typical products
Typical products of cosmetic-grade silicone resins include methyl MQ silicone resins, long-chain alkyl silicone resins, phenyl silicone resins and other series of raw materials. These products have different properties and characteristics to meet the needs of different cosmetics. For example:
MQ silicone resin: has excellent film-forming, hydrophobic and moisturizing properties, and is particularly suitable for use in eye makeup, lip gloss, non-stick lipstick, liquid foundation and other formulation systems.
Phenyl-containing silicone resin products: have a higher refractive index and are used in hair care formulation systems to give hair a more shiny luster.
