Description

"PROCESS FOR PRODUCTION AND FORMULATION COMPOSITION CHARACTERIZED BY STIMULATING HAIR GROWTH AND DARKING WITH ANTI-FALL ACTION"

Patent for the production and formulation composition characterized by stimulating hair growth and darkening with anti-fall action. The hair can be straight, curly or curly and serves as a thermal protector against solar radiation, moisture, dust, atmospheric gases, mechanical action (by brush, comb, nails) and chemical transformations such as perming, pretending, straightening. It consists of three parts: cuticle, medulla cortex. It is a keratin-based fiber with proteinase carbohydrates. The stem is the emerging part of the scalp and the acuticle is the outer layer, formed by several transparent sub-layers. The cuticles are partially overlapping, forming several layers of plaques that protect the cortex. The cortex is the intermediate region of the strand, structured by various chemical bonding forms, such as hydrogen bridges and disulfide bridges, between cysteine groups. The medulla is the central part of the dofio, with one that may be empty or filled with keratin responsive. The hydrolipid layer that protects hair, skin and nail has a pH between 4.2 and 5.8. Thus, all products that come into contact with the human body should be neutral (pH equal to hair, skin and nail) or slightly acidic. Sealing the hair with alkaline shampoo, its cuticles open, dull elephant, difficult to comb and tangled. Normal hair has regular production of fat by the glands, which lubricates the hair from root to tip. Normal hair is a natural feature, but dry or oily hair may have its fat level balanced by the right treatment. Dry hair is the name for non-silky hair, due to poor fat production by the hairy sebaceous glands and is not sufficient to lubricate the hair. even, causing little hydration. Consequently, the hair has little luster and is brittle. A characteristic feature of the dry hair is the fact that the scales that make up the outer layer of the hairs open with the hair most vulnerable to external agents such as pollution, wind, sun and chemical processes such as dyes and perms. Dry hair has little irrigation at the ends, but receives concentrated irrigation at the root, which reduces hair loss.

Oily hair has excessive fat production by the sebaceous glands, and may be oily by natural or acquired condition due to nahigiene irregularity or inappropriate use of hair products. Tends to have irrigation distributed along the wire, decreasing nara irrigation, which increases hair loss. Mixed hair has intermediate characteristics, the scalp is oily and dry-looking.

The hair is covered by closed scales, the cuticles, with protective function and retaining water and proteins. When the scales are opened, by chemical or physical agents, the wire loses brightness and resistance. Damage and hair loss can also be caused by diet, emotional factors and drug reaction. Dandruff and seborrheic dermatitis weaken the bones, cause hair loss and itching. Although there is no cure, treating the scalp with adequate shampoo helps to reduce the intensity and frequency of symptoms. A shampoo consists of one or more cleansing agents, foam stabilizer, conditioner, thickener, opacifier, pearlescent, preservative, essence. , dye and other promotional purpose additives. Surfactants respond by properties such as appearance, foaming, cleaning and conditioning of the wire. Its performance is based on the adsorption of the molecules at the dirt / hair / water / air interfaces, giving rise to micellar bodies. The predominant factor in surfactant action is the hydrophilic-lipophilic balance (HLB) 1 which determines the power of detergency, foaming and viscosity. The most common are sodium lauryl ether sulfate, coconut diethanolamide, cocoamidopropyl betaine, sodium lauryl ether sulfosuccinate and pure or combined ethoxylated sorbitan monolaurate. The correct shampoo type should be prescribed by a professional after examination of the hair and scalp. The primary function of shampoo is to remove dirt from the hair and scalp. The desirable characteristics of a shampoo are:

1. Clean the hair and scalp;

2. Be easily rinsed off.

3. Produce abundant creamy foam;

4. Have odor and pleasant;

5. Not to be irritating to eyes and mucous membranes;

6. have a homogeneous appearance;

7. Leave hair soft, flexible and shiny.

Shampoo Types: There are many specifications of shampoo and the choice should be made with special discretion. Next, the basic formulation and the usefulness of each type.Anti-dandruff: has agents that combat the microbial flora responsible for dandruff, as well as specific actives that combat scalp scaling, obstruction factor of hair follicles. Anti-seborrheic shampoos are found in medicinal or cosmetic formulations, which present, by deregulation, the same active ingredients present in the medicinal version, but in lower concentration.

Anti-Grease: Has high detergent power, which removes excessive greasiness from the scalp and clears the hair follicles. Anti-drop: The actives reduce the greasiness and stimulate the hair bulb's strengthening.

Anti-Waste: has high detergent power and has active want the waste, in depth, and should be used to cadadas. Its pH is above 7.0, which forces the opening of the cuticles.

Volume donor: It has microspheres of plastic derivatives that adhere to the wires and support them in a structured way.

Two in one: shampoo and conditioner, its formulation combinal cleansing and conditioning, being contraindicated for greasy hair, due to the accumulation of the conditioner, of greasy nature.

Strengthener: Contains actives such as keratin or silicone, which bind to the wire and form a protective film, with the aim of reducing breakage.

Moisturizer: Waterproofs the hair and scalp, reducing water tightness and peeling.

Neutral: pH around 7.0, can be used with any type of hair, especially in the event of an allergic process or irritation of the leather, as it is less aggressive to the skin. The pH of the scalp is between 3.8 and 5.6, and the recommended for a frequently used shampoo is between 5 and 7.

No salt: Sodium chloride formulations for thickening dry the hair. Lauryl polyglycosis derivatives, such as PEG -120 and PEG -150, are safer and moisturize the hair and protect and balance the wires.

Thermal: it forms a protective deposit, typically of silicone, that protects the hair fibers against the damage caused by aggressive agents, such as hair dryer and flat iron. colored on the capillary surface, which remains for some washes and should be replaced when fading.

Daily use: With a mild formulation, it is recommended for frequent use because it is not aggressive to the hair.

Assets and Formulation

In the formulation of a shampoo products are used for specific purposes:

1. Soy protein hydrolyzate

Extracted from grains in the initial phase of germination, they constitute a balanced fraction of peptides, mainly in the range 1000 to 10,000 Daltons, and amino acids, obtained by partial protein hydrolysis. It favors the revitalization of skin metabolism and provides essential nutrients to the skin. It is usually used in revitalizing and rejuvenating formulations. The most widespread trademark is Phylderm.

2. Walnut Extract

Walnut leaf contains tannin, quercitin, essential oils, juglone, alpha and beta-hydroxyquinone, among other naphthalones. Walnut extract has antifungal, slightly antiseptic, astringent and healing properties, and is indicated as an auxiliary agent in the treatment against dandruff and seborrhea, with the action of hair loss. It is also used as a dye to darken white hair and as an auxiliary agent in photo protection. Used to treat scalp disorders such as eczema, acne, dermatitis, and damage caused by low temperatures.

3. Minoxidil. Hair has a growth cycle in three phases: anagen (growth), catagen (regression) and telogen (rest). At the end of this process, the wire in the telogen phase is expelled, and another hair follicle appears to replace it. One loses 100 to 150 strands a day. The wire grows 0.35mm per day and each wire has its own cycle, with all wires being replaced in 3 to 5 years. At one point, 80% or more of the follicles are in the anagen phase, less than 1% in the catagen phase, and the rest in the telogen phase. Minoxidil is a biological modifier that reverses the miniaturization process of the yarn in the anagen phase, which is the growth phase of the matrix. Matrix keratinocytes grow rapidly, with a high growth rate compared to other regions of the follicle. The desphase duration in the scalp is 2 to 6 years. With the follicle's normalization of the follicle, by prolonging the anagen phase, minoxidil stimulates scalp vascularization and improves oxygenation of the region, which results in multiplication of the hair root cells. It must be absorbed by the pores to act on the hair's nose, as it has no action on the hair shaft. Its reactive agent is minoxidyl sulfate, marketed under various trade names such as Rogaine and Regaine. It is a vasodilator, originally used to treat high blood pressure, until hair growth was detected as a side effect in people with reversible baldness. Effects such as dryness, itching, and erythema tend to disappear with discontinuation of the drug or after some time of use.

If the patient uses minoxidil for a while to combat baldness and stops applying the product, hair loss will again manifest. The most common side effect, when applied directly to the scalp, is persistent itching. Allergic reactions to minoxidil or propylene glycol, adjunct, are sporadic. Less common side effects when overused include acne in the hair area, headache, hypertrichosis, impotence, very low blood pressure, irregular heartbeat, flushed skin, blurred vision, lack of feeling in the hands, feet or face, decreased sexual desire. , chest pain, rapid weight gain, sweat on the legs, hands, feet or face.

Process

Shampoos are made by simply mixing the components, shaking bottles that can be jacketed for heating by heating. Such vessels usually operate closed and under low pressure, to eliminate the foam. Pastososcopic ingredients tend to be preheated. After the mixing and homogenization procedure, the product is filled. Many shampoos are supplied formulated as a common base by manufacturing companies, receiving the addition of perfume, dye and demineralized water in the bottler, the trademark holder.
