How we scored it

Behenyl-modified dimethicone; this site's convention scores all silicones 0.0 even though the behenyl (C22) substituent may be oleochemical.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

A dimethicone modified with a behenyl (C22) fatty group; the silicone portion is made from silicon metal via chlorosilane chemistry. The behenyl group could be oleochemical, but this site's convention scores the whole class 0.0.

In plain English

A silicone with a fatty group attached, used to condition hair and skin. Despite containing a plant-derived fatty portion, it's classified as a silicone ingredient under site rules.

CosIng definition: Silicones and siloxanes, dimethyl, docosyl methyl, trimethylsilyl terminated
