POLYSOL® PGA

Natural peg free solubilizer with moisturizing properties

INCI name

Polyglyceryl-6 Caprylate, Aqua, Proline

POLYSOL® PGA is an innovative natural solubilizer as an alternative to PEGs. It is obtained from the esterification of polyglycerol and vegetable fatty acids with the aid of proline, an amino acid involved as the catalyst that confers to the product moisturizing and refreshing properties, in addition to a better solubilizing efficacy thanks to the synergy with the ester.

POLYSOL® PGA is well-suited for the solubilization of essential oils, vitamins and liposoluble active ingredients. It works well across a wide range of pH values, including in the presence of mildly cationic substances, offering an efficacious “natural” alternative to traditional solubilizing agents.

POLYSOL® PGA stands out for its dual-benefit profile. Its outstanding solubilizing power enhances the delivery of liposoluble active ingredients, while in cleansing applications, it proves to be gentle yet effective in removing waterproof makeup and excess of sebum.

The inherent Proline’s moisturizing and refreshing properties enhance the skin’s tactile experience, making it an ideal ingredient for cleansers that combine efficacy with sensory benefits.
