FormulaC14H32O3Si · 276.49 Da
FunctionCleansing · Emulsifying Surfactant
FeedstockOleyl alcohol from oleochemical oleic acid, ethoxylated with…

How we scored it

Supplied formula/IUPAC (triethoxy(octyl)silane) is a wrong-compound data mismatch, disregarded per description. Oleyl alcohol 268.48 Da (natural) + 30x ethylene oxide 1321.5 Da (petrochemical) = 268.48/1589.98 = 0.17
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

Oleyl alcohol from oleochemical oleic acid, ethoxylated with petrochemical ethylene oxide. Source data's formula/IUPAC fields belong to an unrelated silane and were ignored.

In plain English

A cleansing and emulsifying surfactant made from oleyl alcohol reacted with a larger number (30 units) of ethylene oxide, making it more water-soluble.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-9-(Z)-octadecenyl-.omega.-hydroxy (30 mol EO average molar ratio)
