How we scored it

Per ~1,000 Da of hydrolysed rice protein (natural), one stearyl-dimethyl-hydroxypropylammonium chloride group: stearyl C18H37 and chloride 288.9 Da natural; hydroxypropyl and N(CH3)2 102.2 Da petrochemical; (1288.9)/1391.1 = 0.93. Same method as Steardimonium Hydroxypropyl Hydrolyzed Wheat Protein.
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

Hydrolysed rice protein quaternised with a stearyl-dimethyl-hydroxypropylammonium chloride reagent.

In plain English

A conditioning ingredient derived from rice protein, modified to carry a mild positive charge so it attaches to hair and skin for a smoother feel. Comes from hydrolyzed rice protein plus a fatty conditioning group.

CosIng definition: Protein hydrolyzates, rice, 2-hydroxy-3-(octadecyldimethylammonio)propyl derivatives, chlorides
