A crosslinked siloxane polymer with a resinous coating, listed as a viscosity-controlling ingredient.
What it is
Polysilicone-22 is, according to CosIng, a complex siloxane polymer made by reacting hydrogen dimethicone with dodecene and crosslinking it with bis-vinyldimethicone; the material is then treated with methyltrimethoxysilane and aminopropyl trimethoxysilane, which form a resinous coating over the crosslinked silicone. CosIng lists it as a viscosity-controlling ingredient.
Where it is used
Appears on the ingredient lists of a small number of products.
Limits of interpretation
The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.
The INCI name does not show the molecular weight or the degree of crosslinking of the polymer.
