Description

COMPOSITION FOR TREATING KERATIN FIBERS

TECHNICAL FIELD

The present invention relates to a composition for treating keratin fibers, in particular the hair. The invention also relates to a process for treating keratin fibers, in particular the hair, using the composition of the present invention.

BACKGROUND

Cosmetic and personal care products for use on keratinous substrates such as hair are available commercially in various forms, for example, as creams, lotions, gels, pastes, and powders. Regardless of the form, these products have to achieve and provide certain benefits and attributes such as efficaciousness, cosmeticity, desirable texture, stable formulations, and ease and convenience of use and application. Thus, in order to meet consumer needs and preferences, manufacturers of such products continuously seek to re-formulate and create new products with enhanced efficacy, while still remaining stable and safe to use.

One area where manufacturers are always seeking to improve in is in the area of hair cosmetic products such as those products designed to change the appearance, shape or configuration of hair as well as to provide hair care benefits of manageability, frizz control, volume reduction, and improved quality of the hair fiber. Examples of such hair cosmetic products are hair relaxers or hair straighteners which can relax or straighten curly or kinky hair, including wavy hair. Other hair cosmetic products are perms and waving compositions for providing curl or shape to hair. These products may increase the manageability and ease of styling hair and they may either be applied in a hair salon by a professional or in the home by the individual consumer.

It is desirable to find alternatives to improve the properties of hair cosmetic products, such as suitable coating amount and good smoothness.
