Hair styling

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).

Her clothes and hair styling were wrong and I could not read her signals. It was unheard of for a lady of the Republic to entertain a man in her husband s absence and the absence of servants made the unspeakable unthinkable. Romantic near-darkness would normally turn hint into blatant invitation. 

Mousses are designed for hair styling and setting hair in position. Commonly, formulations are based on cationic conditioning polymers with quaternary ammonium salts, alcohols, perfumes, colorants, water, and preservatives. They may be in propellant, foam, or jelly form for direct application to hair after shampoo or cutting, see also Fibrous Protein Formulation Chemistry Proteins.

Since chitin and chitosan are nontoxic and nonallergenic, they can be applied on the human body. They have been used in the production of emulsifiers, antistatic agents and emollients to extend the cosmetic product shelf life (e.g., shampoos and hair styling products). 

The fimction of a modern hair gel is to bond the hairs together and maintain hair styling and/or to provide conditioning (usually with an oil or conditioning polymer). Bonding activity is attributable to the presence of film-forming adhesive materials such as polymeric resins or fixatives. The most commonly used resins for this purpose are the water-soluble... 

Poly(/V-vinyl-2-pyrrolidone), PVP, is available in various molecular weights (10,000, 40,000, 160,000, and 360,000) and can yield solutions of varying viscosities. PVP is best known for its unusual complexing ability toward many types of small molecules and for its physiological inertness [19], As a thickener, it is used in biomedical, pharmaceutical, cosmetic, and personal care products (hair styling gels, shaving creams, shampoos, emollient creams and lotions, etc.).

Type 1 fimbriae are composite structures with a relatively rigid 8 nm wide rod tipped by a thin (2.5 nm) more flexible tip fibrillum. b Thin and wavy F17 fimbriated E. coli covered with 1-3 pm long, flexible, 2-3 nm wide fimbriae, c Tangled (capsules and sheaths) Y. pest is FI capsular antigen. No individual fibres are visible, but the capsule consists of a tangle of thin ( 2 nm) flexible fibres. AFM amplitude picture (a) kindly provided by Dr R.
