Description

Title of the invention: KERATIN FIBER TREATMENT COMPOSITION technical field

[0001] The present invention relates to a composition for treating keratin fibers, particularly hair. The invention also relates to a process for treating keratin fibers, particularly hair, using the composition of the present invention. CONTEXT

[0002] Cosmetic and personal care products intended for use on keratinous substrates such as hair are commercially available in various forms, for example, creams, lotions, gels, pastes, and powders. Regardless of their form, these products must offer certain benefits and attributes such as efficacy, cosmetic appeal, a desirable texture, stable formulations, and ease and convenience of use and application. Therefore, in order to meet consumer needs and preferences, manufacturers of these products continually seek to reformulate and create new products with increased efficacy, while remaining stable and safe to use.

[0003] One area in which manufacturers are constantly seeking to improve is that of hair cosmetic products, such as those designed to change the appearance, shape, or configuration of hair, as well as to offer hair care benefits such as ease of styling, frizz control, volume reduction, and improved hair fiber quality. Examples of such hair cosmetic products include relaxers or smoothing products that can straighten or smooth curly or frizzy hair, including wavy hair. Other hair cosmetic products include perms and wave-forming compositions to give curls or shape to hair. These products can increase manageability and ease of styling and can be applied in a hair salon by a professional or at the individual consumer's home.

[0004] It is desirable to find alternatives to improve the properties of hair cosmetic products, such as a suitable amount of coating and good smoothness. Summary of the invention

[0005] An object of the present invention is therefore a keratin fiber processing kit comprising:

[0006] I) a reducing agent composition I), comprising the following components:
