Description
SolaStay P1® (Polyester-25), a bis-methoxycrylene/octyldodecyl adipic acid/methylpropanediol copolymer, is a highly effective singlet state quencher, permitting formulators to combine active ingredients once considered too photo-unstable to be effective. SolaStay P1® is a copolymer that photostabilizes Avobenzone extremely well. As with SolaStay S1, it protects against lost of absorbance much faster than Octocrylene, and is suitable for beach and daily wear products in spray, lotion, cream, balm and gel forms. As a polymer, it may enhance the water resistance of products in which it is incorporated. It is most effective in combination with other photostabilizers. Typical use level: 1 – 5%.
