Shin-Etsu Silicones of America (SESA) debuted its SPD series of sunscreen formulations at the Florida Chapter of the Society of Cosmetics Chemists 2023 Sunscreen Symposium in Lake Buena Vista.
SESA’s SPD series are highly concentrated dispersions of fine particles of titanium dioxide and zinc oxide in avolatile silicone oil (DMF-2cs Dimethicone).
These products are essentially non-whitening, with a silky light skin feel.
SPD-Z7L: Fine Particle Zinc Oxide Dispersion and SPD-T5L: Fine Particle TiO2 Dispersion are stabilized by a proprietary branched silicone-polyglycerin copolymer dispersant that gives the dispersions a high active content with low product viscosity.
Both dispersions can be easily formulated into various formats allowing for the development of mineral sunscreens with minimal to no whitening, high SPF with reduced active content and are aesthetically pleasing.
Also on show were KF-6106: Polyglycerin-Modified Silicone, a polyglycerin-modified, branched silicone surfactant said to have outstanding powder dispersability and superior absorption properties.
KSG-320: Emulsifying Silicone Elastomer meanwhile is an alkyl functionalized silicone cross-linked with polyether and swollen in Isododecane.
This product is a self-emulsifying silicone elastomer with exceptionally silky, smooth skin feel with high degree of optical blurring.
“We recognize the importance of innovating solutions for sunscreen consumers seeking optimal aesthetic effects while providing broad spectrum SPF protection,” said SESA Cosmetics Application Laboratory team leader Janine Cherette.
“This event was an ideal platform to showcase these new functional silicone technologies with a forward-thinking objective of providing solutions to sunscreen formulation challenges,” she added.
