In the field of cosmetics, silicone oil is a popular raw material, and its unique properties give various cosmetics excellent quality.
From the perspective of chemical structure, cosmetic silicone oil is mainly divided into linear silicone oil and cyclic silicone oil. Linear silicone oil has a long chain molecular chain, such as polydimethylsiloxane, which has good lubricity and spreadability, can form a uniform film on the skin surface, effectively reduce the friction of cosmetics on the skin, and bring a smooth feeling of use. At the same time, linear silicone oil can also increase the gloss of cosmetics and enhance the appearance of products.
Cyclic silicone oil molecules have a ring structure, with octamethylcyclotetrasiloxane as the most typical. Cyclic silicone oil has the characteristics of low viscosity and high volatility. It can evaporate quickly when applied to the skin, leaving a dry skin feel. It is often used in antiperspirant products and makeup base makeup to avoid sticky makeup and enhance the makeup effect.
According to functional characteristics, silicone oil can be divided into ordinary silicone oil and modified silicone oil. Ordinary silicone oil has basic lubrication and protective properties. Modified silicone oils gain new functions by introducing specific groups. For example, amino-modified silicone oils can interact with the negative charges on the surface of hair, enhancing the hair's suppleness and antistatic properties, and are often used in hair care products; fluorinated modified silicone oils can enhance the waterproof and antifouling capabilities of cosmetics, and are suitable for waterproof makeup.
It is these different types of silicone oils and their unique properties that continuously optimize cosmetics in terms of feel and efficacy, meeting the diverse needs of consumers.
