In cosmetic products, silicone resin, due to its unique film-forming properties, becomes a key component for enhancing the durability and comfort of the makeup effect. The core of its film-forming action lies in the synergy of the molecular structure and volatility characteristics. The silicon resin molecules contain silicon-oxygen units such as polydimethylsiloxane, which possess both hydrophobicity and flexibility. When the cosmetic containing silicone resin is applied to the skin, the volatile solvents (such as isododecane) in the system rapidly evaporate, leaving the silicone resin molecules to spread and cross-link on the skin surface, forming a continuous and transparent film.
This film plays a significant role in various cosmetic categories. In foundation liquids and primer creams, after the silicone resin forms a film, it can lock powder particles, reducing makeup fallout and smudging, while also providing a smooth touch to the skin. In waterproof mascara and eyeliner, its strong hydrophobic film can isolate sweat and oil, ensuring a long-lasting and non-fading makeup effect. In lip gloss, the film-forming silicone resin can form a thin protective film, delaying pigment loss and water evaporation, achieving long-lasting color retention.
Furthermore, the film-forming layer of silicone resin has excellent breathability， does not clog pores， and is resistant to temperature changes， avoiding makeup breakdown due to environmental factors. With the development of cosmetic technology， modified silicone resins adjust the length of the molecular chain and the degree of cross-linking to further optimize the extensibility and adhesion of the film， meeting consumers' dual demands for "long-lasting makeup effect" and "comfortable skin sensation".
