Ingredient Function
LexFeel™ 7:Light, dry, and spreadable sensory emollient. This ester is excellent for solubilizing UV filters and dispersing pigments. It imparts a non-greasy after-feel and reduces the tackiness of heavier emollients.
LexFilm™ Sun Natural MB: 100% plant-based, liquid film-former. Creates water-resistance and helps to provide an even coverage of product on skin in order to achieve a high SPF rating.
Lexemul® 561 MB: Traditional nonionic emulsification system.
SustOleo™ BA:Brassica-derived structuring agent.
Spectrastat™ E:Alternative preservation system for broad spectrum coverage even at neutral pH.
