Description

DESCRIPTION OF THE INVENTION

Natural solid shampoo based on vegetable fats and plant extracts

The invention relates to a cosmetic product, specifically a solid shampoo which can be used both for the hair and for the body and which derives its unique effects and properties from its rich composition in natural active ingredients obtained from the following plants: henna (Lawsonia inermis), l garlic (Allium sativum), Moringa (Moringa oleifera) and tamarind (Tamarindus indica), the flower of guinea sorrel (Hibiscus sabdariffa).

And also natural fats such as shea butter (Vitellaria paradoxa or Butyrospermum parkii), palm kernel oil (Elaeis guineensis), olive oil (Olea europaea), oil of Carapa procera and coconut oil (Cocos nucifera).

Shampoo or shampoo is a cosmetic product generally presented in the form of a liquid, cream, solid or powder, formulated from surface-active substances making it possible to clean the hair and possibly to treat the hair. The shampoo is applied by massaging into wet hair. We massage the scalp without rubbing the hair too much. There are shampoos for all types of hair: normal, dry, damaged, oily. And even for colored, blond, or frizzy hair. Shampoos wash the hair, make it shine and detangle it.

However, used too frequently, shampoo can destroy the hair's protective film and fat, thereby damaging the hair. Therefore, it is recommended not to wash your hair every day, as this attacks the scalp and stimulates the sebaceous glands which then produce more sebum. There is then a risk of oily roots and dry lengths, because they will not have had time to be protected by the sebum. In fact, the care given to the hair depends on the type of hair. Also, is it recommended to wash oily hair every three days, or even four days, so as not to over-stimulate the sebaceous glands, and normal hair and dry hair once a week, in particular to avoid removing the bit of hair. sebum that protects them.

Originally, the first shampoos were based on black soap and soda crystals, both containing surfactants (detergents). They often left a whitish deposit. Hair could quickly become sticky and tangled. We will have to wait for modern shampoo, the one we know today, to solve these problems. An improved formula was first proposed in the 1930s with Drene, the first synthetic (and non-soapy) shampoo. Then, Eugène Schueller, from L'Oréal launched in 1931 a shampoo based on

-2 synthetic materials, Platinosel, which leaves hair clean and silky. In 1934, it was the turn of Dop, the first general public shampoo.

There are several categories of shampoos. This classification is related to both the composition and the use of the champoing. We then count:

- classic or basic shampoo: it has no other function than washing the hair. It is suitable for normal hair. It is a gentle shampoo, without synthetic products, so as not to disturb the balance of the hair and the scalp;

- care shampoo: it is suitable for aesthetic hair problems: smoothing, volumizing, texturizing, etc. It is based on butter or vegetable oil. It is suitable for curly hair. Because curly or curly hair has a natural tendency to be dry.

- treating shampoo: it meets the needs of different types of hair: nourishing, sebum-regulating, anti-dandruff, etc. It is a nourishing shampoo, based on vegetable oil of olive or sweet almond, or based on shea butter. It is indicated for dry hair and for oily hair. It limits the production of sebum and purifies the scalp with, for example, zinc, mint or nettle;

- dry shampoo: it is used between two traditional water shampoos. Dry shampoo is a mixture of powders that absorb sebum and trap dirt, which is then brushed off. It usually comes in the form of an aerosol, which is more convenient for its application. Dry shampoos are often made with corn or rice starch.

- organic shampoo: classic shampoos are made up of a multitude of products that are often harmful to both health and nature. Organic shampoos use surfactants of plant origin, in particular from coconut: codium cocoyl glutamate; coconut glucoside. They contain natural ingredients or / and from organic farming. They are free from chemical or synthetic ingredients and must have environmentally friendly packaging. This type of cosmetics represents less than 20% of the cosmetics market.

In Europe, advertising claims for cosmetic products must comply with Regulation (EU) No. 655/2013 included in the recommendations of the Professional Advertising Regulatory Authority applicable from July 1, 2019. In particular, a cosmetic product cannot be qualified as a whole of "natural" or "of natural origin" only if its natural content or of natural origin is greater than or equal to 95%.

The present invention, according to its characteristics, belongs to the category of natural and organic mushrooms.

-3The skin is a very important organ which is responsible for allowing perspiration to pass, while preventing foreign bodies from entering the body. These foreign bodies include dust, microbes and toxic molecules. As the body is made up of more than 60% water, the skin must protect itself from drying out (which results in cracks or even cracks). This is why sweat is accompanied by a secretion of a fatty substance: sebum. It therefore allows the skin to maintain its humidity level, and therefore to remain soft, supple and intact. Unfortunately, like any fatty substance, sebum tends to soak up foreign bodies in contact with the skin. On the scalp, sebum also protects the hair by coating the scales and especially the space between the scales with a protective film. This film has two advantages: mechanical protection against dust and chemical protection against oxygen in the air, which will degrade the scales, and against dehydration (dry hair).

Over the days, the sebum will accumulate in the hair, especially in the parts close to the scalp. The movements of the hair also contribute to the spreading of this sebum.

The more the quantity of sebum increases, the thicker the film becomes. The hair becomes "greasy" and has a tendency to stick together, become heavier, giving an unsightly "wet" effect. This environment thus created is conducive to the development of lice and various bacteria. Hence the use of champoing.

Shampoos come in a wide variety of compositions. The legislation obliges brands to indicate the list of ingredients on the packaging of cosmetics in general. This list is called INCI (International Nomenclature of Cosmetic Ingredients). It must imperatively classify the ingredients in order of importance in the composition. Only products that are 1% or less in the product can be sorted in any order.

Industrial shampoos are largely made up of a clever mix of chemical and / or natural ingredients in the following order of importance:

- water: it is the main constituent, it serves as a matrix for all the other components;

- mineral oils and / or silicones: they give the product its textures; their names most often end with "one", "cone" or "xane";

- PEGs (polyethylene glycol): they are used to thicken the shampoo and to gel its texture, they are derivatives of petrochemicals. They are found on the labels under the terms of PEG, PPG or polyethylene glycol;

- washing agents: they dissolve the fat which is entrained in the water with the molecules or particles which it has fixed;

- conditioners: they bring softness and shine to the hair. These are detergents which are generally: ammonium lauryl sulphate, ammonium laureth sulphate, sodium cocosulphate, sodium laureth sulphate, sodium lauryl sulphate, diethanolamine (DEA), triethanolamine (TEA);

- preservatives: these are generally parabens which extend the shelf life of the product. Their names often end with "zoate", and also contain the term "paraben" surrounded by various prefixes and suffixes;

- emulsifying agents: they stabilize the emulsion by preventing the separation of the fatty and aqueous components of the shampoo;

- synthetic surfactants or foaming agents: they provide the foaming effect of industrial shampoos. There are three kinds:

* cationic surfactants: which form a smooth film on the hair and make it soft: these are the most irritating;

* anionic surfactants: they are used to foam the champoing. They are very inexpensive, but also very aggressive on the skin.

* amphoteric surfactants: They are made from renewable raw materials, starch, sucrose or glucose. They have foaming, detergent and anti-static (reduction of static electricity in the hair) properties. They are very well tolerated by the skin and the scalp. These are the surfactants used in organic shampoos;

- natural active ingredients: they are highlighted by advertising, for example Aloe vera, various essential oils, as well as fruit extracts;

- additives: these compounds vary according to the desired effect: they can be anti-limescale agents, pH stabilizers to acidify the shampoo, dyes, perfumes, or fragrance, superfatting agents (oils) to limit the aggression from shampoo, so-called "moisturizing" agents such as honey or glycerin, essential oils extracted from plants, flowers, bark, fruits, etc., detangling agents allowing "two-in-one" shampoos to also serve as a 'after-shampoos, medicinal agents (anti-lice, anti-dandruff shampoos, etc.)

The constituents used for the formulation of conventional shampoos present potential and real dangers for users. The detergents, dyes and perfumes used are generally synthetic. People develop allergies to shampoos or to some of their components, in particular to SDS (Sodium Lauryl Sulfate) which has been known at least since the 1990s to be an irritant and capable of causing dermatitis and pruritus. According to many

-5organisms including OSHA (Occupational Safety and Health Administration), NTP (United States Department of Health and Human Services) and IARC (International Cancer Research Center), SLES is considered to be slightly less irritating than SDS, but could be dangerous because it cannot be metabolized by the liver. Beyond a certain dose, it is a factor of aphthous ulcers.

Referenced in some countries as "rodent wound", some detergents, such as "sodium laureth sulfate", are irritating to the skin and scalp. Silicones, which are used as conditioners in shampoos, suffocate the hair, preservatives such as paraben, but also "methylisothiazolinone", which replaces it in many cosmetics, perfumes and artificial colors are allergenic and also irritating. In addition, their concentration of surfactants, dyes, perfumes and biocidal substances pollutes the natural environment.

Also, let's not lose sight of the fact that existing shampoos get rid of excess sebum and make hair less greasy, but they cannot effectively fight against lice and bacteria. As for organic shampoos, they are rare and expensive.

The current invention, according to its characteristics, aims to develop a less expensive shampoo, free from synthetic components that are irritating, aggressive and toxic to the skin, scalp and hair, and polluting the natural environment. And therefore a champoing based on natural products and which preserves health and the environment.

According to the invention, this object is achieved with a solid shampoo obtained with plant extracts and vegetable fats. The mushroom according to the invention is obtained by a saponification reaction of a mixture of vegetable fats such as shea butter (Vitellaria paradoxa or Butyrospermum parkii), palm kernel oil (Elaeis guineensis), olive oil. olive (Olea europaea), Carapa procera oil and coconut oil (Cocos nucifera) by sodium hydroxide or soda (NaOH) in the presence of water and sodium carbonate and especially in the presence of active ingredients and natural essences extracted from plants such as henna (Lawsonia inermis), garlic (Allium sativum), Moringa (Moringa oleifera), guinea sorrel flower (Hibiscus sabdariffà) and tamarind (Tamarindus indica ). These give the invention antibacterial and antifungal properties which help rid the hair of lice over a period of 6 months, prevent the development of lice and dandruff, and treat certain skin conditions such as yeast infections and warts.

The invention gives the hair suppleness, exquisite beauty, shine and consistency. Indeed, it treats the hair by acting on the hair fiber that it envelops and

-6fortifies by depositing on it a protective sheath which rebalances the hair. Thus, it makes dry hair less dull and less brittle, and for oily hair, it reduces sebum production and prevents hair loss.

The natural solid shampoo based on vegetable fats and plant extracts, according to the invention has a number of advantages: it is natural, therefore free from irritating chemical active ingredients. It is also softening and nourishing and can be used as a scrub for the skin. It hydrates the scalp, fights split ends and prevents hair loss. It is not polluting the environment.

The solid shampoo according to the invention is described below with the aid of a non-limiting manufacturing example. It is obtained by a saponification reaction of a mixture of vegetable fats which are shea butter (Vitellaria paradoxa or Butyrospermum parkii), palm kernel oil (Elaeis guineensis), olive oil (Olea europaea) , Carapa procera oil and coconut oil (Cocos nucifera) by an aqueous solution of sodium hydroxide or soda (NaOH) and especially in the presence of active ingredients and natural essences extracted from plants which are henna (Lawsonia inermis), garlic (Allium sativum), guinea sorrel flower (Hibiscus sabdariffa), Moringa (Moringa oleifera) and tamarind (Tamarindus indica). This preparation is carried out in several stages:

- Preparation of the sodium hydroxide solution: add to approximately 3 L of water, 1 kg of sodium hydroxide or soda (NaOH). An exothermic reaction then occurs which gives a hot solution of sodium hydroxide;

- Cooling: the hot sodium hydroxide solution is cooled rapidly if necessary using an ice or salt water bath or slowly by allowing it to stand in the open air;

- Preparation of the fatty phase: in another container, we introduce by mixing about 1.5 kg of shea butter (Vitellaria paradoxa or Butyrospermum parkii), 0.5 L of palm kernel oil (Elaeis guineensis), 180 mL of Carapa procera oil, 3L of coconut oil (Cocos nucifera);

Saponification: the sodium hydroxide solution obtained beforehand is poured gently and homogenizing, into the composition of the oily phase already prepared;

- Addition of active ingredients: quickly, we add to the mixture undergoing saponification which is still fluid, and still with stirring, the plant extracts such as henna (Lawsonia inermis), garlic (Allium sativum), Moringa (Moringa oleifera) , the flower of guinea sorrel (Hibiscus sabdariffa) and tamarind (Tamarindus indica).

-7 Molding. after stirring the mixture, a homogeneous fluid paste is obtained which is then poured into molds to give, after cooling and hardening, the natural solid shampoo based on vegetable fats and plant extracts.

The plant extracts give the shampoo antimicrobial, specifically antibacterial and antifungal properties. Thanks to these, the invention rids the hair of lice over a period of 6 months and prevents the development of lice and dandruff. It also treats certain skin conditions such as yeast infection and warts.

All of the constituents of the invention treat the hair by acting on the hair fiber; it envelops the latter and strengthens it by depositing on it a protective sheath which makes it possible to rebalance the hair.

All this results in the corollary of giving the hair suppleness, exquisite beauty, shine and consistency. Thus, dry hair becomes less dull and less brittle, as for oily hair, they see reduced sebum production and their fall is avoided.
