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 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
  • 100% plant-derived and palm-free
  • No impact on the odour and colour 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 absence or limited quantities of alcohol.
  • No negative effects on foaming properties when mixed to surfactants.
 

ORIGIN

Ester of Polyglyceryl-6 with Caprylic Acid and Proline

TEST

In neither the “in vitro” nor the human trials did POLYSOL® PGA manifest any detectable sensitising effects; it can be considered hypoallergenic.

It is advisable to not use strong acids or base in order to guarantee the stability of the final product, as these could cause the solubilising agent to saponify.
