Guar gum, 2-hydroxy-3-(trimethylammonio)propyl ether, chloride (CAS 65497-29-2) — Citrus Not applicable Note Fragrance Ingredient
Guar gum, 2-hydroxy-3-(trimethylammonio)propyl ether, chloride
CAS 65497-29-2
What Is Guar gum, 2-hydroxy-3-(trimethylammonio)propyl ether, chloride?
This synthetic compound is derived from guar gum, a natural thickener found in foods and cosmetics. It’s primarily used in industrial applications rather than consumer products. While chemically modified from a natural source, this specific derivative doesn’t play a significant role in fragrance creation or everyday consumer goods.
Safety Profile
PROFESSIONAL USEWhat Does Guar gum, 2-hydroxy-3-(trimethylammonio)propyl ether, chloride Smell Like?
This synthetic guar gum derivative has minimal odor characteristics. As an industrial chemical rather than a fragrance material, it lacks the volatile compounds typically associated with scent profiles. The odor, if detectable at all, would be faintly chemical with possible traces of the parent guar gum’s earthiness.
Chemistry, Properties & Perfumer Guide
The Chemistry
This compound is a chemically modified polysaccharide derived from guar gum. The modification introduces a cationic trimethylammonium group via ether linkage, making it water-soluble and positively charged. Such derivatives are typically synthesized through nucleophilic substitution reactions of guar gum with (3-chloro-2-hydroxypropyl)trimethylammonium chloride under alkaline conditions. These modifications dramatically alter the physical properties while maintaining the polymer backbone structure.
