Alfonal KD

Identification

Chemical description Coconut fatty acid diethanolamide produced from RBD coconut oil via the 1:1 reaction
INCI name Cocamide DEA
IUPAC name Amides, C8-18 (even numbered) and C18-unsatd., N,N-bis(hydroxyethyl)
CAS # 68155-07-7
EC # 931-329-6
Alfonal KD is a nonionic surfactant most commonly used in the formulation of personal care products, cosmetics, laundry and household detergents where it acts as a wetting agent, foam booster and stabilizer, hair/fibre softener, antistatic and re-fatting agent, perfume fixing agent, solubilizer of components heavily miscible with water as well as efficient dispersant and both w/o and o/w emulsifier promoting detergency of the product.
 
Ability of Alfonal KD to increase the viscosity of alkyl ether sulfates (Spolapon products), alkyl sulfates (Syntapon products) and amphoteric surfactants (Flavol products) in detergent formulations is made use of for thickening in all formulations where presence of inorganic salts is undesirable. Alfonal KD is stable in all acidic, neutral and moderately alkaline environments and it is compatible with hard waters and any other types of surfactants.
 
All of this makes Alfonal KD suitable for use in shampoos, bubble baths, liquid soaps, liquid laundry detergents, dishwashing liquids etc. Owing to its unique characteristics, Alfonal KD is applied in many other industrial applications such as coatings and paints, dyes, metalworking, paper and printing industries etc.
