Aminopropyl Magnesium Polysilsesquioxane Chloride
A cosmetic ingredient used as antimicrobial, humectant, skin conditioning in skincare, haircare, and personal-care products sold in the European Union.
What is it?
Aminopropyl Magnesium Polysilsesquioxane Chloride is a resinous material composed of a mixture of three-dimensional siloxane polymers and oligomers with cage structures. For the oligomers, each silicon atom in the polysilsesquioxane is connected via oxygen atoms to three other silicon atoms and can be represented by the empirical formulation RSiO3/2, where R represents the aminopropyl group. For the larger polymeric polysilsesquioxanes, some of the silicon atoms are not connected to other silicon atoms and instead have a silanol (SiOH) group. Aminopropyl Magnesium Polysilsesquioxane Chloride is prepared by the hydrolysis and condensation of 3-aminopropyltriethoxysilane, and reaction with magnesium chloride
What does it do?
Aminopropyl Magnesium Polysilsesquioxane Chloride is listed in the EU cosmetic ingredient inventory with the following declared functions:
-
Antimicrobial
kills or inhibits the growth of microorganisms
-
Humectant
