Phenoxyethanol by The SkinScience Co
Phenoxyethanol is a widely used synthetic preservative that has global approval for use in all cosmetic products in concentrations up to 1%. Phenoxyethanol is incredibly versatile: It works in a large range of formulas and pH ranges, has broad spectrum activity against many pathogens you don’t want multiplying in your skincare products, is stable, and is compatible with many other preservatives used in cosmetics. It is often used in combination with other preservatives such as ethylhexylglycerin.
It is suitable for those who want a product that is non-formaldehyde-releasing, suitable for a wide pH range, offers good protection and stable to hydrolysis so can be used in high temperature mixtures up to 80C.
It is globally approved for this use and is suitable for leave-on and rinse-off products. This is a Broad Spectrum Action preservative preventing growth of Bacteria, Yeast and Mould.
Recommended Usage: Up to 1%
In high risk formulations (containing colours, herbal extracts, biological material (peptides, milk etc), exfoliant particles, clays and muds) we recommend blending the phenoxyethanol with a second, faster-acting preservative such as Piroctone Olamine, Glyceryl Caprylate, Sodium Hydroxymethylglycinate, Potassium Sorbate and Sorbic Acid or an alternative. This is because Phenoxyethanol is a slow acting preservative and can take up to 48 hours to become fully effective in a formula. During that time a high-risk formulation may have enough time to overwhelm the product rendering the phenoxyethanol useless.
