Description and Uses
Sodium dehydroacetate is the sodium salt of dehydroacetate. It is mainly used as a new generation food preservative and food additive, being used extensively in sauce, fruit, bread, cake, moon cake, margarine and beverage. Sodium dehydroacetate (DHA-S) has a wide spectrum of antimicrobial activity that accounts for its use in cosmetic products as a preservative and antimicrobial agent. It is effective in the treatment of both bacteria and fungi. It is also a kind of anticoagulant agent through depleting the blood level of vitamin K.
Geogard(R) 111S preservative is based on dehydroacetic acid (DHA), the sodium salt form (NaDHA) and therefore are recognized by major cosmetic, toiletry and fragrance regulatory authorities worldwide for use in cosmetic and personal care products.
