As an important raw material in the cosmetics industry, silicone emulsion, with its unique molecular structure and performance advantages, has shown wide application value in the fields of skin care, makeup and hair care.Its core ingredient is based on silicone oil, and a stable milky system is formed through emulsification technology. It combines the lubricity, film-forming properties of silicone oil and the moisturizing properties of emulsion, providing multiple functional support for product formulation.


In the field of skin care products, silicone emulsions are commonly used in basic care products such as lotions and creams.Its core role is to form a breathable protective film, which can not only prevent moisture loss, but also avoid the stickiness of traditional oils and fats.For example, polydimethylsiloxane emulsions can reduce the surface tension, making it easier for the active ingredient to penetrate into the stratum corneum, while giving the product a silky touch.In addition, silicone oil emulsions play a synergistic role in sunscreen products, which can improve the spread of sunscreens and reduce the amount of physical sunscreens, making the product lighter in texture.


In the formulation of cosmetic products, the application of silicone emulsions significantly improves the use experience.In liquid foundation, amino-modified silicone oil emulsion enhances the compatibility of powder and oil to achieve long-lasting makeup fit and concealer enhancement.Its film-forming properties can prevent toner migration, and with the emulsifying effect of polyether-modified silicone oil, the product has both waterproof, sweat-resistant and soft-focus effects.For eye makeup such as mascara, silicone elastomer emulsion can form an elastic film, which not only maintains the curl of eyelashes, but also avoids the phenomenon of agglomeration.


The field of hair care is an important application scenario for silicone emulsions.In conditioner, methyl hydrogen-containing silicone oil emulsion repairs hair scale damage by hydrogen bonding with hair keratin, and cooperates with the film-forming properties of polysiloxane protein copolymer to form an antistatic protective layer.For hair dyeing products, amine-modified silicone oil emulsions can promote the penetration of dye molecules, and their positively charged amino groups produce electrostatic adsorption with the negative charge of the hair, which significantly improves the dyeing fastness and gloss.Experimental data show that hair dyes containing silicone emulsions can increase color fastness by more than 30%.


With the development of nanotechnologies, silicone microemulsion has gradually become a hot topic in research and development.Its particle size is less than 100nm, which makes the product easier to penetrate while maintaining the transparency of the formula.In high-end skin care products, nonionic polyether modified silicone oil microemulsion can wrap the active ingredient to achieve sustained release, and optimize the product texture with silicone rheological regulators.In the future, with consumers' dual pursuit of skin feeling and efficacy, silicone emulsions will play a more critical role in formula innovation.
