The 1st Customized Skincare System that Adapts to YOUR Changing Needs


INCI: Phenoxyisopropanol

What is Phenoxyisopropanol?

Phenoxyisopropanol is aromatic ether alcohol. It is a colorless to yellow clear liquid with a mild odor. It is used as a preservative in cosmetic products for many years. However, it has more usefulness in other than cosmetics-related areas.

Use & Benefits:

Phenoxyisopropanol is used as a mild preservative in cosmetic products. Products that are formulated from natural extracts/ oils or those who have water as a solvent may tend to lose their potency when it encounters different environmental problems like changing climate, increased humidity, increased temperature. Moreover, it is much of a problem when the product is opened and underuse. At this point, products may undergo discoloration or deterioration because of fungal or microbial growth.  If un-noticed, used on the skin, may lead to skin infection or other serious problems. So a preservative is necessary to maintain the same product quality as at the beginning throughout the shelf life. Plus, it may affect the harmful bacteria present on the skin and produce body odor or pimples on the skin. When Phenoxyisopropanol is used in a formulation the skin may get protection against those harmful bacteria as well. It is used in formulations of creams, makeup products, lipsticks, bath soaps, cleansers, and other personal care products.
