Dehydroacetic acid Chemical Properties,Usage,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.
Uses
Dehydroacetic Acid (DHA) is a preservative that is a crystalline powder with a solubility of less than 0.1 g in 100 g of water at 25°C. It can undergo a variety of chemical reactions which give it utility in many applications. It is used at 0.01–0.5% for microbiological growth inhibition in various foods. It is used for cut or peeled squash, with no more than 65 ppm remaining in or on the prepared squash.
