Description

A COMPOSITION COMPRISING A HYDROXYPROPYL GUAR HYDROXYPROPYLTRIMONIUM CHLORIDE AND AT LEAST ONE DYE AND / OR ALKALINE AGENTFIELD OF INVENTION

[0001] The present disclosure relates to the field of hair dyeing products, and particularly, to compositions for treating keratin fibres and methods of dyeing and / or lightening of keratin fibres, in particular hair.BACKGROUND OF INVENTION

[0002] The use of personal care products is increasing and in particular hair coloring products are most sought to modify hair color, specifically to mask grey hair. Hair coloring products use a wide range of dyes including oxidative dyes comprising oxidation bases and couplers.

[0003] It is known practice to dye keratin fibres, in particular human keratin fibres such as the hair, to obtain “permanent” colourings with dyeing compositions containing oxidation dye precursors, notably oxidation bases, such as ortho- or paraphenylenediamines, ortho- or para-aminophenols, or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolo-pyridines. These oxidation bases are colourless or weakly coloured compounds which, when combined with oxidizing products, may give rise to coloured compounds via a process of oxidative condensation.

[0004] It is also possible to vary the shades obtained with these oxidation bases by combining them with couplers or colour modifiers. The variety of molecules used as oxidation bases and couplers allows a wide range of colours to be obtained.

[0005] However, the use of these dye compositions may have a certain number of drawbacks.

[0006] In particular, post-application of the dyeing products the dyeing power may be weak, may not attain customer desired shades restricting to a specific range of colours and finally may not satisfy the requirements of customers. Additionally, the dyeing should be stable and should not be affected by external factors or should not fade away for a particular number of washings. Therefore, it is necessary to develop such dyeing products which can meet customer expectations and also that are moreenvironmentally friendly, notably based on ingredients of natural origin, and have good working qualities, are easy to use and give good dyeing properties.

[0007] Thus, there is a need for a composition for dyeing and / or lightening keratin fibres which is capable of resulting in a good performance, notably in terms of dyeing and / or lightening effect, along with superior colour uptake, color vibrancy, and lastingness, and are environmentally friendly with more ingredients that are natural in origin.SUMMARY OF THE INVENTION

[0023] As discussed in the background, among the hair color users there is a growing awareness towards safe and ecofriendly hair coloring products. Hairs are highly sensitive to harsh chemicals which are more prominent in basic colouring products available in the market. The oxidative hair colors are known to cause damage to hair post coloration. Hence, consumers are looking forward to more environmentally friendly formulations comprising natural ingredients in formulation for hair coloration. Therefore, for an effective hair colouring composition with long lasting effects and better shining, the natural ingredientsseem to be a key reassurance of safety and care. Natural guars are known for their cosmetic benefits in hair care, however use of cationic guars in hair color is not appreciated as cosmetic benefits are not so significant and perceivable. Nevertheless, the use of hair colorants with a specific cationic guar i.e., a hydroxypropyl guar hydroxypropyltrimonium chloride of an average molecular weight in a range of 2,000,000 to about 3,500,000 g / mol, aims at minimizing the hair damage and provide long lasting color benefits. Accordingly, the present invention provides a composition comprising said cationic guar with at least one dye and / or alkaline agent to achieve superior performance benefits such as improved dyeing and / or lightening performances, long-lasting color, improved smoothness with better alignment, and softness along with increased shine and reduction in damage of hairs. The present invention further provides a method of dyeing and / or lightening keratin fibres such as hair, comprising applying the composition on said fibres.

The composition has good dyeing performances such as colour uptake, good colour strength, i.e., the intensity of colour, uniform colour, long- lasting colour, good lightening and / or bleaching effect, and also good conditioning properties such as improved nourishment, soft, smooth, and shiny hair. The composition also has good working qualities, such as ease of applying, rinsing and utilizing less amount of water for rinsing. In particular, the composition incorporates ingredients that are natural and / or have natural origin and are therefore biodegradable and do not bioaccumulate. These natural ingredients function synergistically in the composition comprising a hydroxypropyl guar hydroxypropyltrimonium chloride and at least one dye and / or alkaline agent to provide improved cosmeticity, chromaticity, nourishment, and lightening / bleaching effects, while ensuring the composition is environmentally friendly.

[0277] Composition Cl (according to the present invention) for dyeing and / or lightening keratin fibres was prepared using alkaline agent viz. 7.73% (w / w) of ethanolamine, surfactants viz. 1.37%(w / w) of glyceryl caprylate, 0.62% (w / w) of polyglyceryl 4-caprate, 0.4% (w / w) of glyceryl stearate, 0.99% (w / w) of coco glucoside, 0.27% (w / w) of sucrose stearate, fatty acids viz. 0.32% (w / w) stearic acid, 0.26% (w / w) of palmitic acid, 0.02% (w / w) of myristic acid, fatty compounds viz. 6% (w / w) of Melianthus Annuus (sunflower) seed oil, 23% (w / w) of cetearyl alcohol, polyol such as 5% (w / w) of propylene glycol, 0.47% (w / w) of hydroxypropyl guar hydroxypropyltrimonium chloride according to the invention, 1% (w / w) of antioxidant, 0.48 % (w / w) of tetrasodium glutamate diacetate (salt of GLDA), 2% (w / w) of glycol distearate, quantity sufficient of water along with dye components such as p-aminophenol, 2-amino-3-hydroxypyridine, hydroxybenzomorpholine, N,N-bis(2-hydroxyethyl)-p-phenylenediamine sulfate, m- aminophenol, toluene-2,5-diamine in specific weights as mentioned in the Table 1 below.

[0278] Similarly compositions C2, C3, C4 and C5 (according to the invention) and comparative compositions CPI to CP3 were also prepared by mixing said components as mentioned in Tables 1 and 2 below. Compositions CPI and CP2 comprised guar hydroxypropyltrimonium chloride and CP3 comprised hydroxypropyl guar hydroxypropyltrimonium chloride of molecular weight 1,000,000-1,500,000 g / mol.Table 1Table 2

[0279] Similar to C3 and C4 compositions, comparative compositions CP4 and CP5 were prepared respectively with mentioned components but with guar hydroxypropyltrimonium chloride. Further comparative compositions CP6 and CP7 were prepared similar to C3 and C4 compositions but without any guar.Example 2Evaluation of colour strength and colour uptake

[0280] Protocol: The composition C2 (according to the invention) and CP3 (comparative) were independently mixed with oxidizing composition comprising 6% of hydrogen peroxide in a weight ratio of 1 : 1. Each of the mixtures was applied to locks of hair containing 20% natural grey hair, in a proportion of 5g of mixture per 1 g of hair.

[0281] After a leave-on time of 30 minutes on a hot plate at 27°C, the hair was rinsed, washed and dried. Color readings were taken after 3, 6, 9, 12, 15, 18, 21 and 24 shampoo washes.

[0282] The colouring of the hair was evaluated in the L*a*b* system, using a Konica 2600D instrument. The swatch was pressed against the spectrocolorimeter making sure that it is centered horizontally and that the fibers are parallel to each other, and fiber directions are at 90 degrees with respect to the plane of light incidence of the spectrocolorimeter. Proper hair fiber alignment was ensured. The CIELAB 1976 system was used, and the color of the hair was detected via three main coordinates, L*, a* and b*.

[0283] In this system, L* represents clarity and gave the position on a vertical axis ranging from 0 (black) to 100 (white). The lower the value of L*, the darker and more powerful (intense) the colouring obtained. The chromaticity was measured by the values a* and b*, a* representing the red / green component and b* the yellow / blue component.

[0284] Results: The results confirmed that the composition C2 (according to the invention) had a higher color lastingness as compared to CP3 which had a color loss. In particular, the composition C2 encompassed less color fading due to the presence of hydroxypropyl guar hydroxypropyltrimonium chloride according to the present invention. Therefore, it could be observed that presence of hydroxypropyl guar hydroxypropyltrimonium chloride having average molecular weight ranging from 2,000,000 to about 3,500,000 g / mol provided the desired beneficial effects.

[0285] Further, it was determined that the composition C2 showed no fading and maintained the color for the 20% grey hair till 24 shampoo washes. On the other hand, the composition CP3 showed no fading and maintained color only till 21 shampoo washes. Thus, the color fading was lesser with the composition of the present invention and the composition provided color lastingness even after multiple hair washes.

[0286] Color fading with respect to varying the guar was analysed for composition C2, comparative compositions CPI and CP3 comprising different guar and it could be observed that the composition C2 according to the invention resisted color fading even after subsequent hair washing and the provided enhanced color lasting property.

[0287] The extent of hair colouring was also evaluated for the compositions C3, and C4 (according to the invention), CP4, CP5, CP6 and CP7; and corresponding L* values obtained are tabulated in Table 3 below.Table 3

[0288] The color evaluation of compositions with combination of dyes, indicated that the compositions according to the invention comprising hydroxypropyl guar hydroxypropyltrimonium chloride provided better color uptake compared to composition without guar (CP6 and CP7) and composition with a different guar (CP4 and CP5).Example 3Wet combing studies

[0289] Protocol: The composition Cl (according to the invention) and CPI (comparative) were independently mixed with oxidizing composition comprising 6% hydrogen peroxide in a weight ratio of 1: 1. Each of the mixtures was applied to locks of hair containing 90% natural grey hair, in a proportion of 3g of mixture per 20cm of hair.

[0290] After a leave-on time of 30 minutes on a hot plate at 27°C, the hair was rinsed, washed and combed. The wet combining average peak load was analysed and compared with natural, untreated hair and the results are shown in Table 4 below. The lower the wet combing load, easier the wet combing and smoother would be the hair.Table 4showed wet combing average peak load of 81.91, 89.66 and 96.58 gmf respectively, indicating the hair treated with composition of the present invention was smoother compared to untreated hair and hair treated with the comparative composition CPI. Thus, the composition of the present invention provided improved cosmetic benefits and reduction in hair damage.Example 4Zeta potential studies

[0292] Protocol: The zeta potential is the electrical potential at the slipping plane of hair fibers. The zeta potential is caused by the net electrical charge contained within the region bounded by the slipping plane and the magnitude of the zeta potential indicate the degree of electrostatic repulsion between adjacent, similarly charged particles. Lesser the magnitude of the zeta potential lesser the charged species and lesser entanglement with increased smoothness of the hair. The compositions Cl, and CPI as prepared in example 1 was analyzed to determine their corresponding zeta potential in reference to untreated hair.

[0293] Initially the hair fibres were treated with the compositions Cl, and CPI. These treated hair fibres were packed, and an electrolyte was passed through the hairs. Observed values of potential on the treated hairs were studied. Similarly zeta potential for untreated hair was measured.

[0294] Results: The zeta potential of the Cl treated hair showed lesser negative zeta potential value of -0.25 mV as compared to CPI (-3.77 mV) and untreated hair (-47.89 mV). The lesser negative zeta potential value indicated the better sensorial effect due to positively charged species. The composition according to the invention comprised hydroxypropyl guar hydroxypropyltrimonium chloride imparted more positive species and thereby lowered the zeta potential. Accordingly the hair fibers treated with the composition of the present invention were better aligned and exhibited shine, sensorial and conditioning benefits.Example 5Water rinsing studies

[0295] Protocol: The compositions Cl (according to the invention) and CPI (comparative) were independently mixed with oxidizing composition comprising 6% hydrogen peroxide in a weight ratio of 1: 1. Each of the mixtures was applied to locks of hair containing 90% natural grey hair, in a proportion of 3g of mixture per 20 cm of hair.

[0296] Experimental: The composition was applied on the hair and rinsed with the water until rinse water is clear. The volume of water used for washing the composition was different for all the compositions and the time required for rinsing was also calculated.

[0297] Results: It was observed that composition Cl required 4550 mL and CPI required 6500 mL water for rinsing. The time required for rinsing the composition Cl from hair was lesser than the time required for rinsing the composition CPI.ADVANTAGES OF THE PRESENT DISCLOSURE
