The main role of polysiloxane-15 in cosmetics and skin care products is chemical sunscreen. The risk factor is 2, which is relatively safe and can be used with confidence. Generally, it has no effect on pregnant women. Polysiloxane-15 has no acne-causing properties.

The sunscreen band is 290-340nm, which can absorb UVB. Polysiloxane-15 is a chemical sunscreen agent, the first polymer UVB filter composed of chromophoric groups adsorbed on the silicon chain skeleton, and is also an effective light stabilizer. Due to its unique polymeric structure, polysiloxane-15 can produce a synergistic effect when used in combination with other UV filters to increase SPF, which not only provides high-efficiency sun protection, but also provides a dry, silky skin feel. When added to hair care products, polysiloxane-15 stays strong on the hair and provides multiple benefits, including color fading prevention, increased shine, and hair conditioning.
