Cetyl PEG/PPG-10/1 Dimethicone
The details
This ingredient is a silicone-based emulsifer that helps the water and oil phases play nicely together. It's pretty effective because one end of the molecule loves oil and the other one loves water. Besides holding formulas together, it also leaves a silky and lightweight feel on skin without the greasiness. A manufacturer also claims it can help with the controlled release of active ingredients. The CIR Expert Panel found this ingredient to not be sensitizing in concentrations up to 15% in human maximazation testing and dimethicone-based compounds were not comedogenic. It has a high molecular weight well above 1,000 g/mol which means it limits meaningful skin penetration. A 2019 study specifically tested this ingredient and found no observable Malassezia growth in its presence.
