Potassium sorbate

Potassium sorbate, a white, odorless crystalline powder, is the potassium salt contained in sorbic acid obtained through a synthesis process. Sorbic acid is found in nature mainly in rowan berries. It has an antimicrobial function against yeasts and fungi and is therefore used in cosmetics as a preservative, in fact it is considered harmless to the skin as it is metabolized in the human body through water and carbon dioxide. It does not tolerate pH higher than (approximately) 5 and to obtain optimal conservation of the product it must be combined with one or more preservatives, usually with sodium benzoate. In cosmetics it is widely used in various lotions, creams and hair products, as it is highly tolerated by the skin, with a low environmental impact. It is present in most of our products.
