How we scored it
Where it comes from
The backbone is guar gum from guar beans, etherified with petrochemical propylene oxide (hydroxypropyl) and sodium chloroacetate (carboxymethyl). Actual substitution levels vary by supplier grade, so typical mid-range values were assumed.
In plain English
A thickener made from guar bean gum that has been chemically modified with carboxymethyl and hydroxypropyl groups to improve how it dissolves and thickens formulas.
CosIng definition: Guar gum, carboxymethyl 2-hydroxypropyl ether, sodium salt
