Abstract
Provided is a method for improving fragrance persistence by applying a composition including, as active ingredients: oil; and non-ionic polymers having hydrophobic substituents at both termini thereof. In the composition of the presently claimed subject matter, the non-ionic polymers having hydrophobic substituents at both termini thereof form a flower micelle structure by capturing oil and a fragrance through the hydrophobic substituents, and thus can stably maintain the oil and fragrance and prevent fast volatilization of the fragrance, thereby improving fragrance persistence.
