Diamond Hazard Value Description
1
1 0
Health   1 Exposure would cause irritation with only minor residual injury (e.g. acetone, sodium bromate, potassium chloride)
Flammability   1 Materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Includes some finely divided suspended solids that do not require heating before ignition can occur. Flash point at or above 93.3 °C (200 °F). (e.g. mineral oil, ammonia)
Instability   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

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.

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.

Safety Profile

Poison by ingestion. Moderately toxic by intraperitoneal route. Questionable carcinogen with experimental tumorigenic data. Combustible when exposed to heat or flame. When heated to decomposition it emits acrid smoke and irritating fumes.
