Organosiloxanes have begun to occupy an important position in daily cosmetics. Nowadays, skin care, hair care, shampoo, and makeup products containing organosiloxanes have been recognized by people. At the same time, more and more organosilicone compounds are used in personal products. The formulation of care products has been more widely used.

Silicone compounds used in skin care and makeup products mainly include volatile silicone oil (DC345), medium and low viscosity silicone oil, special silicone oil (cosmetic grade silicone oil, high refractive index silicone oil, alcohol ether silicone oil, silicone acrylate, aerosol particles), silicone emulsifiers, silicone-silicone oil mixtures, silicone volatile silicone oil mixtures, silicone dimethicone oil mixtures, alkyl-modified silicone waxes, silicone emulsions, silicone elastomers, silicone oils and vegetable oil mixtures.

The organic silicon compounds added to shampoos of hair cleaning products include high-viscosity dimethyl silicone oil, amino silicone oil, amino silicone emulsion, dimethyl silicone oil emulsion, and silicone elastomer emulsion. These substances are added to the formula. , effectively improve the wet and dry combability of hair during the cleaning process, increase the smoothness, flexibility, color protection, light benignity, repairability, antistatic and thermal protection, making the hair soft, smooth and non-toxic. tangled.

Silicone oil added to hair care products rinse-off conditioners, leave-in conditioners and styling products, including volatile silicone oil, medium viscosity silicone oil, high viscosity silicone oil mixture, amino silicone oil, special silicone oil, silicone volatile silicone oil Mixture, silicone dimethyl silicone oil mixture, amino silicone emulsion, dimethyl silicone emulsion, silicone elastomer emulsion, in which silicone polyether, silicone emulsifier, alkyl modified silicone wax are used in leave-in conditioners and It has been widely used in styling products.

The potential application of silicone in personal care products is to protect hair from ultraviolet rays, protect hair structure and color; provide cell protection and anti-aging, protect hair from dryness, brittleness and hair loss caused by hair dyeing and perming, and protect hair from pollution, sunlight, and weather Damage to hair caused by sports, exercise, etc. are the main potential applications.

Challenges encountered in the application of silicones in hair care products are that silicones may cause the hair surface to seal - colorants cannot penetrate into the hair fiber, silicones may affect the uniformity of coloring, and silicones may cause hair to be washed out prematurely. , organic silicone may affect the stability of the formula, organic silicone oil may cause silicone oil deposition in the hair, and amino silicone oil microemulsion can reduce the washability of temporary hair dyeing.

Basic research on new types of organosiloxanes will still focus on developing and discovering new structures of organosiloxanes for use in personal care formulations, and applying components from skin care products to hair care products. Different substitutions are tried on existing technologies to obtain new organosiloxanes. In terms of performance, organosiloxanes increase the strength of hair, protect hair from damage, and assist in long-lasting color maintenance in hair care products. This is the direction in which silicones will continue to be researched and developed in the future.
