Amodimethicone is recognized for its extremely robust conditioning and for its ability to form clear products when used in high-surfactant shampoos. Amodimethicone is a useful ingredient in conditioners, gels, mousses, and permanents, but its use in shampoos has proved troublesome due to interactions between the cationic and the anionic surfactants, which can result in compatibility problems. However, the amodimethicone emulsion can be made compatible in high-surfactant-level shampoos
Amodimethicone is typically an emulsion-polymerized polymer; however, utilizing linear processing technology amodimethicone fluids may be prepared as neat fluids, and then emulsified by a mechanical process as desired. The most widely utilized amodimethicone emulsions contain as the surfactant pair either (1) tallowtrimonium chloride (and) nonoxy- nol-10, or (2) cetrimonium chloride (and) trideceth-10 or -12. These "uncapped" amino- functional silicone compounds may be characterized by a linear or branched structure. In either case, amodimethicone polymers will undergo a condensation cure reaction during drying to form a somewhat durable elastomeric film on the hair, providing wet- and dry- combing benefits, lowering triboelectric charging effects, and increasing softness of the dry hair. They are excellent conditioning agents, often found in conditioners, mousses, setting lotions, and less frequently in 2-in-1 shampoos
Amodimethicone is the most widely used amino-modified silicone. It has an aminopropyl group attached to the methyl group of Dimethicone. Amodimethicone of various degrees of amino modification are available as well as those that have POP, POE, or an alkyl group attached. Amino-modified silicones are cationic and affinitive to hair keratin. They are particularly highly affinitive to damaged hair, which is anionic due to the presence of cysteic acid
...and amodimethicone, which is an amino-substituted silicone and silicone quats, which contain permanently quaternized ammonium groups. In general, amodimethicones and silicone quats condition better than dimethicones, which condition better than dimethicone copolyols
