What is Potassium Sorbate?
Potassium Sorbate is the INCI (International Nomenclature of Cosmetic Ingredients) name for potassium sorbate, a preservative agent. Potassium sorbate is a potassium salt of sorbic acid. It is notably used as a food additive, found in yoghurts, drinks, and sauces. In its natural state, potassium sorbate is present in the Rowan tree.
Potassium Sorbate, what is its purpose?
Potassium sorbate is also utilised in the field of cosmetology as a preservative agent. It inhibits the growth of microorganisms in preparations. It aids in combating the formation of yeasts and moulds in water-based preparations. Its role is thus to extend the lifespan of skincare products. It is also used for its ability to reduce or inhibit the odour or even the taste of the base of the preparations. It is particularly used to preserve formulas that include an even base. The maximum concentration allowed according to European regulations is 0.6%. Its concentration should be 0.1% to 0.2% if it is combined with other preservatives.
Potassium Sorbate is found in intimate wipes, makeup removal gels, and body creams.
