How we scored it
Cyclotetrasiloxane silicone homopolymer reacted with 1-tetradecene (petrochemical alpha-olefin); this site's convention scores all silicones 0.0 → 0/total = 0.0.
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
Made by polymerising cyclic methylsiloxanes and reacting them with 1-tetradecene, a synthetic alpha-olefin. This site's convention values all silicones at 0.0.
In plain English
A silicone-based conditioning ingredient that smooths hair and reduces foaming. Made by reacting silicone polymers with a petrochemical-derived olefin.
