Description

HAIR COMPOSITIONS COMPRISING A MODIFIED POLYSACCHARIDE AND

MULTIVALENT IONS

TECHNICAL FIELD

[0001] The invention relates to hair compositions comprising a modified polysaccharide and multivalent ions. The compositions exhibit surprisingly effective reduction of colour washout from chemically-dyed hair. The compositions may be used in the care of keratin fibres. The invention also relates to a method of reducing colour washout from chemically-dyed hair comprising applying the hair composition to the hair.

BACKGROUND

[0002] The importance of care products with the longest-lasting possible effect is increasing not least due to the great stressing of hair, for example, by colouring or permanents, as well as by cleaning the hair with shampoos and by harmful environmental factors. Care products of this type influence the natural structure and properties of hair. Thus, after such care treatments, for example, the wet and dry combability of hair, the hold, and fullness of the hair can be optimized or the hair can be protected from an increase in split ends.

[0003] It has long been customary, therefore, to subject hair to a special after-treatment. In this regard, the hair is treated with special active substances, for example, quaternary ammonium salts or special polymers, usually in the form of a rinse-out conditioner. Depending on the formulation, the combability, hold, and fullness of the hair can be improved by this treatment and the splitting rate reduced.

[0004] Similarly, products for modifying the natural hair colour play a prominent role in hair cosmetics. Permanent, semi-permanent, or temporary colouring systems are differentiated which are based on chemical and/or natural dyes. The hair colours produced artificially by permanent, semi-permanent, or temporary colouring systems have the disadvantage, however, that they can change in an undesirable way, for example, during or after the cleaning of hair.

[0005] An -undesirable change" is understood to be the fading or bleeding and the loss of colour brilliance of the hair shade achieved by the particular dyeing. Environmental effects and/or the effects of sunlight can intensify these changes still further.

[0006] There continues to be a need to provide active substances or active substance combinations for hair compositions with good care properties, which, moreover, strengthen the adhesion of dyes to hair fibres and thus maintain the fastness of the artificially produced hair colour, and in this respect to develop hair compositions further.

100071 The provision of hair compositions that have a beneficial effect in terms of reducing colour washout from chemically-dyed hair is therefore a relevant objective in the field of hair cosmetics.

BRIEF SUMMARY

[0008] The object of the present disclosure is solved by the subject-matter of the independent claims, wherein further embodiments are incorporated in the dependent claims.

DETAILED DESCRIPTION

[0009] The following detailed description is merely exemplary in nature and is not intended to limit the disclosure or the application and uses of the subject matter as described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

[0010] The objective is achieved in accordance with the invention by a hair composition comprising: a) hydroxypropyl guar hydroxypropyltrimonium chloride having an average molecular weight ranging from about 2,000,000 to about 3,500,000 g/mol; and b) at least one divalent or trivalent metal salt. The hair composition may take any form, preferred is a shampoo, conditioner or treatment.

[0011] The compositions as disclosed herein result in considerably greater stability of artificial colourings against washout of the dye. In this way, chemically coloured hair may be washed and/or treated considerably more frequently with the compositions contemplated herein, without resulting in undesirable bleeding or fading of the colour.

[0012] The present invention also provides a method of reducing colour washout from chemically-dyed hair comprising applying to the hair a hair composition as defined herein [0013] The present invention also provides the use of a hair composition as defined herein to reduce colour washout from chemically-dyed hair.

[0014] The invention summarised above will now be illustrated in further detail 100151 Component (a) in the inventive hair composition Is a hydroxypropyl guar hydroxypropyltrimonium chloride having an average molecular weight ranging from about 2,000,000 to about 3,500,000 g/mol. Such guars were surprisingly found to exhibit advantageous effects in terms of reducing colour washout from chemically-dyed hair, particularly when used in combination with salts of multivalent ions, as defined herein. Preferably, the hydroxypropyl guar hydroxypropyltrimonium chloride has an average molecular weight ranging from about 2,300,000 to about 2,900,000 g/mol. Average molecular weight can be measured by any suitable means, as will be well understood by the skilled person. For example, static light scattering measurements can be performed using Gel Permeation Chromatography (GPC). A suitable system is GPC-MALS (multi angle light scattering).

[0016] A further characteristic of the hydroxypropyl guar hydroxypropyltrimonium chloride is its viscosity; suitably, the viscosity ranges from about 600 to about 1200 mPa.s, more preferably from about 750 to about 850 mPa.s. In all instances disclosed herein, the viscosity is the Brookfield RVT viscosity measured at about 25°C and about 20 rpm, Spindle 2, at a concentration of 1 pbw in water.

[0017] A particularly preferred hydroxypropyl guar hydroxypropyltrimonium chloride for use in the present invention is present in the raw material Polycare0 Split Therapy, available from Solvay.

[0018] The total amount of hydroxypropyl guar hydroxypropyltrimonium chloride may range from about 0.001 to about 5.0 wt%, based on the total weight of the composition. The best effects were observed when the amount of hydroxypropyl guar hydroxypropyltrimonium chloride ranges from about 0.01 to about 3.0 wt%, based on the total weight of the composition, for example from about 0.05 to about 2 wt%, suitably from about 0.05 to about 1 wt%.

[0019] Component (b) in the inventive hair composition is a divalent or trivalent metal salt, or a mixture of such salts. Preferably, the or each salt is selected from the group consisting of organic or inorganic salts of copper, zinc, iron(H), calcium, magnesium, iron(III), lanthanum(III), and aluminum. Suitably, one of these salts is present as component (b). Alternatively, two of these salts are present as component (b). Alternatively, three of these salts are present as component (b). Preferred counterions for the metal salt include halides (preferably chloride) and lactate.

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 treatments, 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.
