Functions
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Surfactant Emulsifying
Moisturizing
Locks in moisture to keep skin soft and supple throughout the day
Strengthens Barrier
Mixes oil and water
Traditional Use
A modern synthetic emulsifier made from glucose derivatives and caprylic acid combined with polyethylene glycol. Created to provide gentle, plant-based emulsification properties suitable for sensitive skin formulations.
