Dehydroacetic acid Chemical Properties,Uses,Production

Chemical Properties

white to light yellow crystal powder

Uses

Dehydroacetic acid (DHS) is used as stabilizer for cosmetic and pharmaceutical products due to its fungicide and bactericide activity, as additive for PVC-stabilizers and for the syntheses of veterinary medicines. Product Data Sheet

Uses

Geogard(R) 111a preservative is based on dehydroacetic acid (DHA) and therefore are recognized by major cosmetic, toiletry and fragrance regulatory authorities worldwide for use in cosmetic and personal care products.

Uses

Geogard(R) 221 preservative is based on dehydroacetic acid (DHA) and benzyl alcohol, and therefore is recognized by major cosmetic, toiletry and fragrance regulatory authorities worldwide for use in cosmetic and personal care products.

Uses

Geogard(R) 361 preservative is based on six synergistic components, all with wide global regulatory acceptance: dehydroacetic acid (DHA); salicylic acid; benzoic acid; phenoxyethanol; benzyl alcohol; and benzethonium chloride.

Uses

antifungal, antibacterial

Uses

dehydroacetic acid is a preservative with low sensitizing potential. This is a weak acid used as a fungi-and bacteria-destroying agent in cosmetics. The presence of organic matter decreases its effective ness. It is not irritating or allergy causing when applied on the skin.
