Some commonly used moisturizers such as glycerin, when added in large amounts of skin care products and makeup products, will produce a greasy feeling, resulting in products that are not easy to distribute and spread to the skin; However, when panthenol or niacinamide are added in large amounts in skin care products and color cosmetics, it will cause stickiness. In order to improve the spreadability and pleasure of skin care products and color cosmetics products, it is generally necessary to add low relative molecular weight siloxane fluid to give the cosmetic composition a dry, smooth, uniform touch, and increase visual luster. However, the low relative molecular weight siloxane fluid gives the desired properties to the composition at the same time, its volatile and low viscosity characteristics make it not easy to retain in the preparation, easy to separate, and may even flow uncontrolled through the skin during use, limiting its application in cosmetic compositions.
If common thickeners are used to increase the viscosity of the solution and slow the evaporation loss of volatile low relative molecular weight silicone oils, it may reduce the paintability of silicone fluids and leave a severe slippery feeling on the skin. Silicone gels for cosmetics can be regarded as effective thickeners for low relative molecular weight siloxane fluids, providing unique dry, silky and other skin feelings, so they have become daily chemical raw materials with great development potential and have good market application prospects.
