Hair conditioning

Hair conditioning can be associated with almost any hair product sold in the marketplace because they all claim some benefit to the hair when used. Thus the term hair conditioner can be appHed to such products as rinses, hair dressings, setting lotions, and hair sprays. Conditioners are used to provide different effects to the hair primarily ease of combing, sheen, and soft feel. 

Tertiary Amine-Containing Copolymers. Copolymers based on DMAEMA (dimethylarninoethyl methacrylate) in either free amine form or quatemized with diethyl sulfate or methyl chloride have achieved commercial significance as fixatives in hair-styling formulations, especially in the weU-pubhcized "mousses" or as hair-conditioning shampoo additives. This success has occurred because the cationic charge affords substantive resins that strongly adhere to the hair (141). 

Excessive degreasing by shampoos can be overcome by treatment with an after-shampoo (cream) rinse or a hair dressing. It is considered desirable to control the effects of excessive surface degreasing at the time of shampooing. A wide variety of hair-conditioning additives has been recommended and tested. Only a few have gained wide acceptance, for example ...

Commercially important surfactants based on heterocyclic structures are relatively few in number (B-80MI11510) the most important are the cationic compounds derived from imidazoline (48). Cetyl pyridinium halides (49) are used as germicides and sanitizing agents. Piperidinium (50) and morpholinium (51) compounds find application in hair conditioning formulations as antistatic agents. Substituted oxazolines (52) are a class of cationic dispersants and corrosion inhibitors. 

Imidazolinium derivatives are recommended as detergents, emulsifiers, wetting and hair conditioning agents, foaming agents, fabric softeners, and antistatic agents. There is some evidence dial in cosmetic formulations certain imidazolinium derivatives reduce eye irritation caused by sulfate and sulfonate surfactants present in these products. 

The cosmetic industry provides a wide assortment of formulated products. A typical bathroom contains a full range of perfumes, moisturizers, rouge, lipstick, antiaging skin products, face powder, emollients, nail polish, sunscreen, hair conditioning and coloring products, aftershave, drugs, and deodorants as well as medications.
