Description

Composition for conditioning hair Technical Field The present invention belongs to the field of cosmetics. In particular, the present invention relates to compositions, preferably compositions for conditioning hair. The present invention relates to a method for conditioning hair. Background Consumers tend to use scalp-resident essence (leave-on) when they perceive their scalp problems, dandruff, scalp sensitivity, hair loss, etc. Some resident products typically contain high concentrations of hydroalcoholic soluble actives. In order to obtain more percutaneous absorption or penetration through the hair follicle, an easy way is to ensure a concentration gradient, which means that a large amount of active ingredient remains on the surface. In general, a large amount of active ingredient will cause an undesirable tacky feel to the consumer on the scalp and hair roots. Thus, there is a need for an effective solution for a good feel of hair. Disclosure of Invention It is therefore an object of the present invention to develop a composition, preferably for conditioning hair, which gives a good fibre feel. Thus, according to a first aspect, the present invention provides a composition, preferably for conditioning hair, comprising: a) At least one cellulose-based polymer; b) At least one nonionic surfactant; (c) 1.5 to 30% by weight, relative to the total weight of the composition, of at least one hydroxy acid, and D) At least one carboxylic acid of formula (I) and/or a salt thereof: R1-N-(CH(R2)COOH)2(I) Wherein: -R 1 represents a hydrogen atom or a -CH(COOH)-(CH2)2-COOH、-CH2CH2OH、-CH(CH3)COOH、-(CH2)2N(COR3)-CH2-COOH or-CH (COOH) -CH 2 -COOH group, and R 2 represents a CH 2 COOH group when R 1 represents a hydrogen atom or R 2 represents a hydrogen atom when R 1 is a group other than a hydrogen atom, and -R 3 represents a linear or branched alkyl group comprising 1 to 4 carbon atoms or a cycloalkyl group comprising 3 to 30 carbon atoms. The inventors have found that the composition according to the invention can effectively give a good fibrous feel, including softness and/or a non-greasy feel, and/or is less tacky. According to a second aspect, the present invention provides a method for conditioning hair comprising applying a composition according to the present invention to hair. Other subjects and features, aspects and advantages of the present invention will become even more apparent upon reading the following detailed description and examples.
