Description

Gel type reducing agent for hair}

The present invention relates to a composition of a first agent for wavenant wave, which is a reducing agent for human hair, and more particularly, to a composition of a first agent of a gel type based on carboxyvinyl polymer and hydroxyethyl cellulose as a water-soluble polymer.

Most of the permanent wave solvents currently used are composed of a first agent and a second agent. The first agent is mainly composed of a reducing agent for cleaving disulfide bonds in the first process of wave formation. The second agent corresponds to the second process of forming a new disulfide bond to form a wave, and is mainly composed of an oxidizing agent.

By the way, the first type of liquid type, which is mainly used at present, does not require careful effort for the treatment of the first agent during wave treatment, but the treatment time is fast, but since it is a liquid type, it may flow along the scalp when treating the first agent, causing discomfort. People with weak scalp may have scalp damage due to skin irritation.

There is also a cream-type permanent wave, which is mainly formulated for straightening, which is inconvenient because the hair is often broken and broken when combing to the plate during the procedure and the weight is applied to the head due to the weight of the plate. In addition, since a large amount of oil is contained, the penetration of the substrate is slow, and there are problems in that the procedure is uncomfortable due to the forced adhesion by the cream formulation.

Accordingly, the present inventors have made diligent studies to solve the problems associated with the conventional technology as described above. As a result, the present invention provides a variety of advantages when the composition of the conventional pharmaceutical preparation is changed, and provided in a gel form. It has been found that the invention can be completed.

Accordingly, in one aspect, an object of the present invention is based on the total weight of the composition 1.0 to 5.0% of carboxyvinyl polymer and 1.0 to 5.0% of hydroxyethyl cellulose as a water-soluble polymer, 5.0 to 7.0% of thioglycolic acid as a reducing agent or thio 10.0 to 14.0% of glycolate (ammonium salt, monoethanolamine salt, or sodium salt), 2.0 to 5.0% of monoethanolamine or 2.0 to 5.0% of ammonia water (28%) as an alkaline agent, and disodium ethane 0.05-0.2%, 0.5-3.0% of polyoxyethylene lanolin as emulsifier, 0.3-1.0% of polyoxyethylene-cured castor oil, 0.5-2.5% of cetanol, 0.5-3.0% of stearic acid, 0.5-3.0% of liquid paraffin, Reducing agent composition for human hair, comprising 0.1 to 2.0% of sterimonium chloride, 0.2 to 6.0% of glycerin, and 2.0 to 6.0% of propylene glycol, a slight amount of fragrance and purified water as components for improving usability. To provide for.

Hereinafter, the present invention will be described in more detail.

According to one aspect of the present invention, based on the total weight of the composition, 1.0 to 5.0% of carboxyvinyl polymer and 1.0 to 5.0% of hydroxyethyl cellulose as a water-soluble polymer, 5.0 to 7.0% of thioglycolic acid as a reducing agent or thioglycolate (ammonium salt) , Monoethanolamine salt, sodium salt) 10.0 to 14.0%, a gel-type human hair reducing agent composition comprising 2.0 to 5.0% of monoethanolamine or 2.0 to 5.0% of ammonia water (28%) as an alkali agent is provided. .

According to a further aspect of the present invention, in addition to the above composition, disodium editiide as a stabilizer is 0.05 to 0.2%, polyoxyethylene lanolin 0.5 to 3.0% as an emulsifier, polyoxyethylene hardened castor oil 0.3 to 1.0%, and an oil phase component. Cetanol 0.5-2.5%, stearic acid 0.5-3.0%, liquid paraffin 0.5-3.0%, sterimonium chloride 0.1-2.0%, glycerin 0.2-6.0%, propylene glycol 2.0-6.0%, Provided is a reducing agent composition for human hair comprising a trace amount of flavor and purified water.

As a result of various tests on the components of the composition according to the present invention, as a water-soluble polymer, 1.0 to 5.0% of carboxyvinyl polymer, 1.0 to 5.0% of hydroxyethyl cellulose, and 10.0 to 14.0% of ammonium thioglycolate salt, monoethanolamine 2.5-3.5%, disodium ethane, 0.2%, polyoxyethylene lanolin 0.5-3.0%, polyoxyethylene hardened castor oil 0.3-1.0%, cetanol 1.0-1.5%, stearic acid 0.5-1.0%, Optimal results included 1.5-2.0% of liquid paraffin, 0.1-0.5% of stearmonium chloride, 0.2-6.0% of glycerin, and 2.5-6.0% of propylene glycol.

Most preferably, 3.0% of carboxyvinyl polymer, 3.0% of hydroxyethyl cellulose, 10.0% of ammonium thioglycolate salt, 3.0% of monoethanolamine, 0.2% of disodium ethane, 3.0% of polyoxyethylene lanolin, Polyoxyethylene hardened castor oil 0.8%, cetanol 1.2%, stearic acid 0.8%, liquid paraffin 1.7%, sterimonium chloride 0.4%, glycerin 1.0%, propylene glycol is a composition comprising 6.0%, carboxy When the content ratio of vinyl polymer and hydroxyethyl cellulose is large or small, the effect of the perm is reduced and the usability is deteriorated.

Reducing agents for permanent wave are mainly composed of thioglycolic acids as main components and cysteines as main components. In contrast to thioglycolic acid-based wave solvents, the wavenant having a main component of cysteine has a low odor irritability and a weakness to hair, but a weak wave forming power. The other components are the same as the wavenant wave solvent mainly composed of thioglycolic acids, but upon reduction, the cysteine itself is oxidized to cystine, and crystallized into a white powder which is poorly soluble in water, and easily adheres to the fingers. In the present invention, the parnant wave solvent containing thioglycolic acid as a main component may be thioglycolic acid or salts thereof as the reducing agent. Examples of the salts thereof include ammonium salts, monoethanolamine salts, sodium salts and the like. Thioglycolate salts react with metal ions such as copper and iron to color, and depending on the state of use, deterioration of the appearance and reduction of the reducing ability requires attention to purification of the water and raw materials used. Salts can be used with alkaline agents to adjust the strength of the wave.

In the human hair reducing agent first preparation composition, ammonia (or aqueous ammonia), an amine, an ammonium salt, or a basic amino acid may be used as the alkaline agent. Among them, ammonia is widely used because it has an appropriate swelling effect on the hair and no residue due to volatilization, which is advantageous in terms of safety. In addition, monoethanolamine is also used a lot because it is odorless, so there is a risk of remaining in the hair because it is not volatile. Monoethanolamine neutralizes the carboxyvinyl polymer, which is an acidic polymer, so that the monoethanolamine is included in the present invention in consideration of the fact that it has a viscosity increasing action and is odorless.

Water-soluble polymers have the property of imparting viscosity, allowing the combination of straight and wave treatments. During the wave treatment, the viscosity does not flow, thereby reducing irritation to the scalp, and because it is a polymer type containing a large amount of water, the penetration of the substrate is fast, there is a natural adhesion, and there is no hair damage. In the present invention, a carboxyvinyl polymer and hydroxyethyl cellulose containing a large amount of water and suitable for viscosity provision were selected. The carboxyvinyl polymer is mainly polymerized with acrylic acid and preferably contains 57.7 to 63.4% of the carboxyl groups. Other water soluble polymers may be difficult to maintain the gelled formulation due to the low viscosity of the product when reacted with thioglycolic acid or salts thereof. In addition, components that can perform the same function will be apparent to those skilled in the art, and therefore these components are intended to be included within the scope of the present invention even if not specifically described herein.

As a stabilizer, nonionic surfactants can be mainly used as chelates such as EDTA salts (e.g., disodium ethane), active ingredients, and emulsifiers. In the present invention, polyoxyethylene lanolin and Polyoxyethylene hardened castor oil was selected. And cethanol, stearic acid, liquid paraffin added to the oil phase component is added and cationic surfactant, oil, etc. are blended to improve the usability, the components that can be preferably used in the present invention is stearmonium chloride, glycerin, propylene glycol It mixes suitably.

As other components added to the reducing agent composition for human hair of the present invention, perfume and purified water are blended. Fragrance is used in small amounts, and purified water is added in an appropriate amount depending on the state of the reducing agent.

Gel-shaped human hair reducing agent according to the present invention can be packaged in a tube or a pump container, which has the advantage of easy storage and use. In addition, it is possible to use a combination of straight and wave by using a water-soluble polymer, that is, carboxyvinyl polymer and hydroxyethyl cellulose, to avoid the conventional troubles of the cream type during the straight procedure and the liquid type formulation during the wave procedure. And disadvantages of the existing formulations are improved. Furthermore, in addition to the advantage of not having to comb excessively during the straight procedure and can be performed with a thin oil paper instead of a heavy plate, in the wave procedure there is a gel-like viscosity does not flow can reduce irritation to the scalp. In addition, since the preparation of the present invention is a polymer type containing a large amount of water, the penetration of the substrate is fast, there is a natural adhesion, and there is no hair damage.
