Description

ANHYDROUS AGENT FOR TREATING KERATIN FIBRES

[0001] The present invention concerns an anhydrous agent, which can be used as a cosmetic composition for treating keratinous material, the anhydrous agent being in concentrated form. The present invention also concerns the use of the concentrate for treating and/or caring for hair, in particular, human hair.

BACKGROUND

[0002] Products for caring for human hair have been known for a long time and are offered on the market mainly in liquid or pasty form in suitable packaging End users remove the required quantity of product from the packaging and dispose of it after emptying. Standard commercial hair cosmetic products often contain at least about 70% by weight water and require a commensurate size of packaging. Products having a relatively high concentration of active substances have the advantage of lower packaging costs, lower preservative demand and less expensive storage. However, there are also highly concentrated and even anhydrous products which are attended by numerous disadvantages.

[0003] An object of this invention is to provide a hair composition in concentrated form which serves as the basis for a product which can be used for effective hair treatment, in particular, hair conditioning.

BRIEF SUMMARY

[0004] The above object(s) is achieved in a first aspect of the invention, by an anhydrous agent for the care of keratinous fibres, comprising: a) at least one branched or linear C8-C30 alkane; b) at least one branched or linear C10-C22 fatty alcohol; c) at least one C2-C8 alcohol selected from branched or linear monohydric or dihydric C2-C8 alcohols; and d) at least one emulsifier.

[0005] The anhydrous agent of the first aspect easily forms an emulsion by mixing it with water and adding light amounts of energy (for example, stirring or shaking). This emulsion is ideal for the care of human hair. The particular combination of ingredients surprisingly improves combability of the hair, increases its shine and positively influences hair feel.

[0006] As used herein, the term "anhydrous" is to be preferably understood as meaning that water is present in an amount less than about 5%, more preferably less than about 3%, most preferably less than about 2%, based on the total weight of the anhydrous agent.

[0007] It will be understood that the anhydrous nature of the composition gives rise to a concentrated product. The consumer adds water to the composition to form an emulsion for application to the hair. Thus, the present invention provides a method of using the anhydrous agent as defined herein, comprising mixing the anhydrous agent, and stirring and/or shaking the mixture. The present invention also provides a method of treating keratin fibres, comprising mixing the anhydrous agent as defined herein with water, stirring and/or shaking the mixture, applying the resulting product to keratin fibres, and optionally rinsing the product from the keratin fibres. The present invention also provides the use of an anhydrous agent as defined herein for smoothing a keratinous material, for the care of a keratinous material and/or for the care and cleaning of a keratinous material.

[0008] Preferably, there is no alkali metal hydroxide present in the anhydrous agent according to the present invention.

[0009] In the present application, keratin or keratinous fibres are preferably understood as human hair, human skin and human nails, in particular, fingernails and toenails. Keratinous fibres are particularly preferred to human hair, especially head and/or beard hair.

[0019] As component d), the anhydrous agent comprises emulsifiers, so that its components can be homogenised and form a homogeneous phase in the manufacture of the ready-to-use cosmetic product.

[0020] The person skilled in the art understands that cosmetic products often contain at least one surfactant selected from cationic, anionic, amphoteric, zwitterionic and/or nonionic surfactants. Suitably, the emulsifier present in the anhydrous agent defined herein is selected from one or more of: i) one or more cationic surfactants; one or more fatty alcohol alkoxylates, with a degree of alkoxylation of 2-120, preferably 4-80, more preferably 6-60, yet more preferably 8-40, wherein the fatty alkyl chain length is C4-C30, preferably C6-C25, more preferably C8-C22; and iii) one or more alkyl sulfates with a chain length of C8-C30, preferably C10-C25, more preferably C12-C22.

[0021] Preferably, the anhydrous agent of the present invention is used as a hair conditioner or hair treatment, so the anhydrous agent preferably comprises at least one cationic surfactant and optionally at least one anionic, amphoteric, zwitterionic or nonionic surfactant Thus, the anhydrous agent may preferably comprise: i) one or more cationic surfactants; and optionally ii) one or more fatty alcohol alkoxylates, with a degree of alkoxylation of 2-120, preferably 4-80, more preferably 6-60, yet more preferably 8-40, wherein the fatty alkyl chain length is C4-C30, preferably C6-C25, more preferably C8-C22; and/or iii) one or more alkyl sulfates with a chain length of C8-C30, preferably C 10-C25, more preferably C12-C22.

[0022] Cationic surfactants carry a positive charge in their hydrophilic part. This positive charge causes the surfactant molecules to attach themselves to the negatively charged skin and hair surface. In this way they neutralize the charge, prevent hair from flying, have a smoothing effect, increase hair shine and improve wet combability. Primarily they are used in conditioners, hair conditioners and cures, rarely in shampoos. In addition, cationic surfactants have a co-conservative effect in cosmetic products due to their bactericidal effect, i.e. their bacterial inhibitory effect.

[0023] In principle, all cationic surfactants suitable for use on the human body are suitable as cationic surfactants in compositions according to the invention. These are characterized by at least one water-solubilizing cationic group, such as for example a quaternary ammonium group, or by at least one water-solubilizing cationizable group, such as for example an amine group and furthermore at least one lipophilic alkyl group having about 6 to 30 carbon atoms, or also by at least one imidazole group or at least one imidazylalkyl group.
