Description

FIELD OF THE INVENTION

The present invention relates to conditioning and shine enhancing compositions for keratin fibres especially human hair. More specifically, the present invention relates to compositions comprising synthetic mica coated with metal oxide or metal oxides.

BACKGROUND OF THE INVENTION

Hair conditioning compositions have widely been used for improving primarily combability of hair and furthermore enhancing smoothness, elasticity and shine. Many type of conditioners have been found on the market varying from emulsions, which are generally rinsed of from hair after application and certain period of processing time, to low viscosity lotions used without rinsing off after application. Hair shine improvement has been one of the main areas of development. Hair shine is very much related to the surface structure of hair and this varies very much with the degree of damage either by environmental effects or chemical treatment of hair such as permanent shaping or oxidative colouring. Although consumers with healthy non-damaged hair are generally satisfied with hair shine, shine of damaged hair is usually found to be unsatisfactory. There have been studies aiming improving shine of especially damaged hair.
Conditioner either leave-in and rinse off types have been widely used in hair dressing area. In the last decade especially leave-in conditioning compositions have gained much attention starting from Europe and still increasingly growing in Asian markets.
Leave-in conditioning compositions are especially found appropriate by consumers as they can generally be applied at the sites where necessary and the processing time does not have to be predetermined and more importantly washing hair after certain processing time is not needed.
Shine is an important property of hair indicating its healthiness and cosmetically appealing look. Although shine enhancing preparations are widely available, there is still need for improvement.
Additionally, shine enhancing of hair together with other hair care benefits are increasingly been found as main product benefit. Among other products, products with two physically separated phases at zero share rate have recently been put onto market.
For example WO 02/060397 discloses dual phase conditioning and styling composition for heat styling hair. According to the document compositions comprise an oil phase comprising volatile oil and an aqueous alcoholic phase comprising styling polymer, an emulsifier and salt. The document does not address at all shine enhancing of hair and especially does not disclose any composition which may fall within the scope of the present invention.
EP 996 408 discloses dual phased compositions for make up cleansing wherein a polyvinylpyrrolidone copolymer is used as a demixing agent. The documents does not address at all hair care application of such composition.

Such materials are commercially available from Sun Chemical Corporation and known with their INCI names Synthetic Fluorphologopite.
The particle size distribution of synthetic mica coated with a metal oxide or oxides is in the range of 1 to 750 μm, preferably 1 to 250 μm, more preferably 1 to 100 μm and most preferably 20 to 95 μm. The particle sizes referred are relating to the volume particle size distribution meaning that particles found in the coated synthetic mica having volume particle size in the given ranges.

As a rule any cationic surfactant is suitable for the compositions of the present invention. With the term cationic surfactant it is meant that the surfactant carries a cationic charge when used in the compositions. In other words, compounds having no cationic charge but when added into the compositions protonate and therewith become cationic are also included within the definition of cationic surfactant. An example to such may be stearyldimethylamine and PEG-2 Cocamine are as a compound not carrying a cationic charge but when used in a composition having acidic pH becomes cationic by protonation.
Preferably at least one cationic surfactant is selected from the compounds with the general formula
where R₁s a saturated or unsaturated, branched or non-branched alkyl chain with 8-22 C atoms or

The compositions of the present invention may be transparent or turbid. Turbidity may be caused by the presence of synthetic mica particles or any other ingredient.
With the term thickened liquid, it is meant that the compositions comprise additionally a thickening agent.
With the term gel it is meant that the compositions comprise additionally a gelling agent and the gelling agent is a polymer forming a shear thinning gel.
The thickening agents include any polymer either natural or synthetic thickening aqueous composition. Examples are cellulose and its derivatives such as hydroxyethylcellulose, guar and its derivatives such as hydroxypropyl guar. In the selection of the thickening gels compatibility with cationic surfactant should be carefully examined.
The gelling agents include polymers either synthetic or natural forming shear thinning compositions. Examples to the natural polymers are xanthan gum and its derivatives. Synthetic shear thinning polymers may be those of acrylate polymers wherein compatibility with cationic surfactant should carefully be examined prior to use. Concentration of the thickening and/or gelling agents should be in the range of 0.05 to 5%, preferably 0.1 to 2.5% by weight calculated to total content. It should also be noted that gelling and thickening polymers can be used together.
Another preferred form is oil in water (O/W) emulsion. Emulsions according to the present invention preferably comprise at least one fatty alcohol with linear of branched alkyl chain. Suitable ones are fatty alcohols having 12 to 22 C atoms in its alkyl chain. Examples are myristyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol and their mixtures. Preferred are cetyl, stearyl and behenyl alcohol and their mixtures i.e. cetearyl alcohol. Fatty alcohols may be included into the compositions of the present invention at a concentration of 0.1 to 20%, preferably 0.5 to 15% and more preferably 1 to 10% by weight calculated to total composition.
Emulsions should also comprise at least one emulsifier. It should be noted that quaternary ammonium compounds with single alkyl chain mentioned above are preferred as emulsifiers as well.
In addition to the cationic surfactants with single alkyl chain, additional emulsifier can be incorporated into the compositions. These additional emulsifiers are surface active substances such as non-ionic, amphoteric or zwitterionic and anionic compounds. Because of the compatibility issues of the anionic surfactants and cationic surfactants mentioned above, anionic surfactants are less suitable and therefore their compatibility should carefully be examined. Otherwise, the compositions of the present invention preferably should substantially be free of anionic surfactants. Preferred emulsifiers are cationic, non-ionic, amphoteric or zwitterionic surfactants. The most preferred additional emulsifiers are non-ionic surfactants.
Suitable non-ionic surfactants are alkyl polyglucosides of the general formula
R₇—O—(R₈O)_nO-Z_x

The average degree of ethoxylation thereby ranges between about 2.5 and about 25, preferably about 10 and about 20.
Among the non-ionic surfactants mentioned above fatty alcohol ethoxylates are the most preferred ones. Above mentioned non-ionic surfactants can also be used as mixture of one category such as several ethoxylated fatty alcohols or several categories such as mixture of alkyl polyglucoside and ethoxylated fatty alcohol.
