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.

LexFeel® D4: This volatile sensory enhancer is a silicone-free emollient that mimics the properties of cyclomethicone.

LexFilm™ Sun: Provides both excellent waterproofing as well as UV filter solubilization.

Phenostat™: Preservation system for broad spectrum coverage even at neutral pH.
