Novel mixtures of sugar amides or sugar amines are disclosed that have improved thermal properties over the individual components. New feedstocks based on both the surfactant tail as well as the sugar head group allow for improved physical properties of sugar amide surfactant mixtures and thus improved formulatability. Furthermore, new sources of unique methyl esters from both bioengineering and or co-metathesis of fats and oils provide novel and improved sugar amide surfactant mixtures.

An erodible anhydrous film useful in delivering active agents to a surface including keratinous surfaces, and hard or soft surfaces is disclosed. The erodible anhydrous film contains polyethylene oxide in combination with a support polymer, and optionally, other additives for skin care, fabric care, or hard surface cleaning. The erodible anhydrous film is useful when used as a comfort strip for enhancing shaving.
