Description

Technical Field

[0001] The present invention relates to a composition for treating keratin fibres, in particular hair. The present invention also relates to a method for treating keratin fibres, in particular hair, using the composition according to the invention. Background Art

[0002] Cosmetic and personal care products for use on keratinous substrates such as hair are commercially available in a variety of forms, for example as creams, lotions, gels, pastes and powders. Regardless of the form, these products must achieve and provide certain benefits and attributes, such as effectiveness, cosmetic properties, desired texture, stable formulations, and ease and convenience of use and application. Therefore, in order to meet the needs and preferences of consumers, manufacturers of such products are constantly seeking to reformulate and create new products with enhanced efficacy while still remaining stable and safe to use.

[0003] One area that manufacturers have been seeking to improve is the field of hair cosmetics, such as those products designed to change the outward appearance, shape or configuration of hair and provide hair care benefits, such as manageability, curl control, volume reduction and improved hair fiber quality. Examples of such hair cosmetics are relaxers or straighteners, which can relax or straighten curly or curled hair (including wavy hair). Other hair cosmetics are perms and curling compositions that are used to provide curl or shape to hair. These products can increase manageability and ease of hair styling, and they can be applied by professionals in hair salons or by individual consumers at home.

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