Sodium Dehydroacetate, sodium salt of dehydroacetic acid, which is used as a preservative against the growth of bacteria, yeast and fungi. It is made by the process of neutralizing and reacting the dehydroacetic acid to form its sodium salt. It is ideal for water-based formulations used in personal care products and cosmetics like shower gels, in the food industry and many more.

Cosmetics & Personal Care:
Sodium Dehydroacetate acts as a preservative in personal care products and cosmetics, helping to extend shelf life by inhibiting the growth of bacteria, yeasts, and fungi. It effectively prevents spoilage in water-based cosmetic and makeup formulations.
Food Industry:
It is used in dairy and food products such as margarine, cheese, starch-based products, cakes, and breads to prevent the growth of mould and improve product shelf stability.
Pharmaceutical Products:
In pharmaceutical formulations, Sodium Dehydroacetate helps maintain sterility and functions as a preservative in ointments, topical creams, gels, and other external-use preparations.

Sodium Dehydroacetate is gluten free. It is often used as a preservative in gluten-free products to extend its shelf life.
Sodium Dehydroacetate is derived from dehydroacetic acid through the synthetic process by neutralising dehydroacetic acid with sodium hydroxide.
Sodium Dehydroacetate is generally considered as safe for the hair and is used in various haircare products like conditioners and shampoos to inhibit the growth of microorganisms.
Sodium Dehydroacetate is a synthetic preservative which is chemically synthesised through controlled industrial processes. Its cchemical structure is identical to dehydroacetic acid which can occur naturally.Â
