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 photo stabilizes 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%.
