Clariant's new Aristoflex^™ SUN for elevated suncare formulations

New advanced rheology modifier stabilizes UV filters for long-lasting formulation integrity
Aristoflex SUN enhances SPF performance for optimized sun care formulations
Delivers luxurious textures with elegant skin feel

MUTTENZ, April 23, 2025 - Global specialty chemicals company, Clariant, has unveiled its new, advanced rheology modifier that tackles sunscreen formulation challenges by combining superior stability, SPF performance and luxurious sensory appeal.

The launch aligns with the growing "Skinification of sun care" (or daily sun care) trend, where SPF is increasingly integrated into daily cosmetic products, reflecting consumer demand for multi-functional skincare solutions that combine UV protection with diverse skin care benefits.

Designed for sun protection products and daily UV protection, Aristoflex SUN (INCI: Ammonium Acryloyldimethyltaurate/Beheneth-25 Methacrylate Crosspolymer (and) Sodium Polyacryloyldimethyl Taurate) stabilizes UV filters while enabling light, fresh textures. This new rheology modifier addresses the rising demand for lightweight textures in daily SPF products.

"With the growing trend toward multi-functional skincare products, Aristoflex SUN helps formulators elevate sun care solutions with superior stability, SPF performance and sensory appeal," said Sophia Kim, Global Marketing Manager Skin Care at Clariant. "As experts in rheology modifier technology, we deliver solutions that meet the market's need for high-performance, protective products."

The cold-processable Aristoflex SUN offers formulators the convenience of a pre-neutralized polymer that excels in thickening and texturizing while ensuring optimal UV filter stability.

Aristoflex^™ IS A TRADEMARK OF CLARIANT.
