- 100% plant-derived and RSPO
- No impact on the odor and color of final formulations.
- Easy to use, it works well across a wide range of pH values and provides moisturizing properties.
- It can enhance the fragrance persistence on the skin for a long period due to the absence or limited quantities of alcohol.
- No negative effects on foaming properties when mixed with surfactants.
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.
