Parsol SLX (INCI: Polysilicone-15) is a silicone-based UV-B absorber. This colorless-to-pale yellow viscous liquid integrates easily with the oil phase of sunscreen formulation. PARSOL SLX is the first polymeric UV-B filter consisting of chromophores attached to a silicone backbone and is an effective photostabilizer for PARSOL 1789. When combined with PARSOL HS, this product can achieve a very high SPF (>30), enabling day care or sunscreen formulations that leave a dry, silky touch on the skin.
Parsol SLX is a silicone based UV-B absorber. It added to rinse-off and leave-on hair products delivers multiple benefits including prevention of colour fading, gloss enhancement and conditioning. As a stabilizing ingredient that is used in sunscreens, its job is to slow down the rate of degradation of the sun-absorbing chemicals.
