Definitions

• the invention relates to a cosmetic composition for the treatment of hair but also of hair and hair follicles, intended for recoloration of white hair, by a pigmentation mechanism.
• This composition is based on lead acetate and sulfur, in a hydroalcoholic solvent and glycerin.
• Oxidation dyes are used for this. These are hair fiber dyes that are formed when certain strong oxidizing compounds are used to obtain the desired color.
• PTDA paratoluylene diamine
• PPDA paraphenylene diamine
• the result of these two mechanisms is the deposition of a colored pigment on any hair shaft which restores a natural-looking color to the hair.
• the application of the lotion must first be carried out daily for a period of 20 to 30 days, then in maintenance, it is applied, regularly, two to three times a week.
• These lead acetate-based hair lotions have the advantage of acting gradually. In fact, after applying the lotion to the hair, the reaction between lead acetate and the sulfur in keratin is slow and the lead salts are gradually fixed on the cuticle and in the cortex of the hair.
• compositions however have side effects which can become severe. They cause very rapid degradation of the cuticle of the hair shaft, revealing the cortex which, by losing its natural protection, is exposed to attack. The hair then becomes dry, brittle, lose its flexibility and is difficult to style. They can even cause a disruption of the sebaceous glands and the scalp.
• the object of the invention is the development of a hair lotion, intended for the hair in particular, but also for the hairs as well as for the hair follicles, which acts according to the same process, but which, while retaining the progressive effectiveness , does not have the disadvantages.
• Document GB-1 283 892 discloses a hair composition for regenerating the color of the hair comprising, in a hydroalcoholic solution, 1.5% by weight of lead acetate, 1% by weight of sulfur, 0.5 % by weight of benzalconium chloride and 2% by weight of a mucopolysaccharide, the incorporation of the latter being intended to improve the appearance of the treated hair.
• the contribution of this ingredient does not allow in any case to limit the amount of any of the active ingredients responsible for the degradation of the hair, which remains significant.
• the Applicant has discovered that it is possible to increase the effectiveness of the compositions based on lead acetate and on sulfur, currently available, while reducing the amounts of these active principles, and to eliminate the major defect, namely drying of the treated hair.
• the Applicant has arrived at such a composition by adding panthenol and a mixture of essential oils.
• the treatment of the hair, hair and / or hair follicle with a composition of the invention visibly increases the quality of the colored hair or hair.
• an object of the invention is a cosmetic composition for the treatment of hair, body hair and hair follicles, based on lead acetate and sulfur, in a hydroalcoholic solvent and glycerin, said composition comprising panthenol (or vitamin B5) and a mixture of at least three essential oils chosen from a Saint Thomas bay essential oil, an ylang-ylang essential oil, and a cedar essential oil.
• hydroalcoholic solvent and glycerin is meant a mixture of water, alcohol, preferably ethanol, and glycerin.
• glycerin is intended to mean a fatty alcohol obtained by saponification of fatty substances, preferably synthetic or of vegetable origin, conventionally used in moisturizing cosmetic compositions.
• the proportion by weight of alcohol in the composition of the invention is preferably greater than 10% to allow a homogeneous mixture of the various ingredients, but must not reach too high proportions to prevent the composition from becoming irritating. That of glycerin is preferably greater than or equal to 1.5% and less than or equal to 3%.
• the proportion by weight of lead acetate relative to the total weight of the composition varies from 0.10 to 0.60%, preferably from 0.25 to 0.60%, and / or the proportion by weight of the sulfur relative to the total weight of the composition varies from 0.10 to 0.50%, preferably from 0.25 to 0.50%. It is observed that these quantities are much lower than those recommended in the prior art. As indicated previously, the composition described in GB-1 283 892 1.5% by weight of lead acetate and 1% by weight of sulfur.
• the proportion by weight of panthenol relative to the total weight of the composition preferably varies from 0.1 to 4%, or better still from 0.4 to 2%.
• a composition of the invention as defined above can also comprise at least one activator of the oxidation reaction. This is advantageously chosen from ammonium acetate and ammonium chloride. An optimum proportion by weight of said activator is approximately 0.10% relative to the total weight of the composition, if it is ammonium acetate, and approximately 0.40% relative to the total weight of the composition if it is ammonium chloride.
• a composition of the invention as defined above can also comprise at least one other essential oil preferably chosen from the following oils: rosemary essential oil, lavender essential oil and sage essential oil.
• the action of a composition of the invention can also be supplemented by an anti-dandruff action, an anti-seborrheic action, a vitalizing action and / or a styling action.
• a composition advantageously comprises at least one agent capable of imparting anti-dandruff and / or antiseborrhoeic and / or vitalizing and / or styling properties to the cosmetic composition.
• a composition of the invention improves the quality of the hair, in particular from the point of view of its hold, its shine, its vitality, the ease of styling; it also improves the condition of the scalp and is therefore recommended for dandruff and seborrhea problems.
• a composition of the invention will preferably be applied daily, for approximately 20 to 30 days, then, in maintenance, it will be applied approximately two to three times per week, or even less, since according to the invention , a coloration is obtained more quickly.
• a composition of the invention can be in various forms such as lotion, gel, milk, cream or foam.
• proportions by weight of the various ingredients of a composition of the invention relative to the total weight of the composition are preferably the following:
• a preferred mixture comprises: from 0.02 to 0.2% essential oil of Saint Thomas bay (Pimenta racemosa), preferably 0.05% from 0.02 to 0.2% of oil ylang-ylang essential oil (Cananga odorata), preferably 0.03% from 0.02 to 0.2% essential oil of cedar (Cedr ⁇ s atlantica), preferably 0.02% from 0.02 to 0.2% essential oil of rosemary (Rosmarinus officinalis), preferably 0, 03% from 0.02 to 0.2% lavender essential oil (Lavandula angustifolia), preferably 0.02% from 0.02 to 0.2% sage essential oil (Sa / via officinalis), preferably 0.02%.
• composition of the invention a mixture of the following ingredients is carried out at room temperature: water, alcohol, glycerin, panthenol, and essential oils. The solution obtained is then filtered to remove insoluble compounds and possible contaminants. Then, at room temperature, lead acetate and sulfur are added with stirring, preferably 3000 revolutions per minute.
• other ingredients can be incorporated to extend the properties of a composition of the invention, for example other essential oils recognized to be active on the properties of the hair and scalp or improving the fragrances of the cosmetic composition.
• Example 1 Formulation of a composition of the invention This example provides a formulation of a preferred composition of the invention.
• composition formulated below does not contain benzalconium, panthenol or essential oils.
• composition formulated below does not contain benzalconium or essential oils, but it does contain panthenol.
• panthenol has a revitalizing action on the hair, but above all that in terms of coloring efficiency, it makes it possible to compensate for the decrease in the quantities of lead acetate and sulfur. We thus observe an unexpected role of panthenol.
• composition formulated below is a composition of the invention. Compared to a conventional composition, it does not contain benzalconium, the amounts of lead acetate and sulfur are reduced, and it includes panthenol and a mixture of essential oils of bay of St. Thomas, ylang-ylang , cedar, lavender, rosemary and sage, according to a formulation of a preferred composition of the invention.
• BIO means that the essential oil comes from a guaranteed non-irradiated organic culture, without pesticides or herbicides.
• a composition of the invention makes it possible to recolor the hair more quickly, while containing greatly reduced amounts of lead acetate and of sulfur, and being free of benzalconium chloride. It is surprisingly observed that the reduction in the active principles does not affect the effectiveness of the composition, and that this reduction is precisely compensated by the panthenol and the mixture of essential oils. The aggressive constituents being in more limited quantities and partly replaced by revitalizing constituents, the quality of the treated hair is considerably improved.
