Description

Hair styling gel compositions

The present invention relates to a hair styling (hair dressing) gel composition. More specifically, the present invention is 0.1 to 10.0% by weight of the acrylic / polyoxyethylene alkyl ether methacrylate copolymer, 0.1 to 10.0% by weight of the acrylic copolymer, acrylic / hydroxy esters acrylic A hair styling gel composition comprising 0.1 to 10.0% by weight of a polymer and 0.01 to 10.0% by weight of a neutralizer.

There are many ways to make your hair look the way you want it, but it can be summarized in two ways. One method of chemical treatment is to change the binding position between cysteine residues in the protein constituting the hair to restructure and reorganize the hair, thereby permanently changing the curl pattern of the hair. Generally, spray, mousse, gel, etc. As a temporary fixation of the hair using a styling product called, there is a physical method which is easily removed by water or shampoo. Generally, the main component of a hair styling product is a polymer compound, which is classified into two types. One is a natural polymer compound, Cellulose, Pectin, Gelatin, and derivatives thereof. The other is a synthetic polymer compound obtained from petroleum. Polyvinylpyrrolidone (PVP) Nonionic or cationic polymers such as, PVP / VA copolymers, PVP / dimethylaminoketyl methacrylate copolymers and the like are frequently used. The purpose of hair styling products is to fix and maintain the hair in the desired shape. The most important raw material for this function is polymer. Hair styling products are divided into hard, soft, etc. according to the ability to fix and maintain the styling (setting force), which is influenced by the user's preference or a fashionable hairstyle.

The most important part of this hair-styling agent is how well it is made, how long it lasts, and is non-sticky during use, and there is no flaking. However, nonionic or cationic polymers such as polyvinylpyrrolidone (PVP), PVP / VA copolymer, PVP / dimethylaminoketyl methacrylate copolymer, etc., which are widely used in setting polymers, have a strong film. However, the film is broken by external action (combing, hair curling, etc.), easily flaking occurs, and also has a disadvantage in that the styling is weak due to the weak film under high humidity conditions.

The present invention has been made to solve the above problems, it is to achieve in the present invention is to provide a styling composition giving a strong setting force, no stickiness, no flaking phenomenon.

The present invention is different from the styling composition made by adding a setting polymer to a gel obtained by neutralizing an alkaline carbomer solution using an alkaline agent, to an acrylate / polyoxyethylene alkyl ether methacrylate copolymer and an acrylate copolymer. The styling gel composition prepared by neutralizing and increasing the setting polymer of the acrylics / hydroxyesters acrylics copolymer with a neutralizing agent was able to solve the above problems that may appear during styling.

Acrylates / polyoxyethylene alkyl ether methacrylate copolymers (Hydrophobically-modified Alkali Soluble Emulsion) are synthesized with monomers linked with hydrophobic groups based on acid / acrylate copolymers as a basic structure. Polymers, the acrylic copolymer is a copolymer of one or more monomers of acrylic acid and methacrylic acid, and the acrylics / hydroxyesters acrylic copolymer is one or more monomers of acrylic acid and methacrylic acid Copolymers with one or more monomers of hydroxyacrylate esters.

Acrylate / Hydroxyesters Acrylate copolymer shows the setting power by neutralizing acrylic acid by neutralizing agent, and the proper content of neutralized polymer improves solubility in water and usability with thickener, etc. It is optimized to improve strong setting force.

Accordingly, it is an object of the present invention to provide a styling composition which gives a strong setting force, is not sticky and free from flaking.

The present invention is an acrylates / polyoxyethylene alkyl ether methacrylate copolymer as 0.1% to 10.0% by weight of thickener and 0.1 to 10.0% by weight of an acrylic copolymer, acrylates / hydroxyesters as a setting polymer It relates to a hair styling gel composition comprising 0.1 to 10.0% by weight copolymer, 0.01 to 10.0% by weight neutralizer.

The acrylates / polyoxyethylene alkyl ether methacrylate copolymers contain 0.1 to 60.0% by weight of hydrophobic monomer units.

The composition according to the present invention contains 0.01 to 10.0% by weight of the neutralizing agent to neutralize the above-mentioned thickener to have a viscosity. As the content of the neutralizing agent increases, the transparency becomes better, but the pH increases and the stickiness increases, so it is preferable to use 0.01 to 10.0% by weight based on the total weight of the composition.

Neutralizing agents applicable to the present invention include triethanolamine (TEA), potassium hydroxide, aminomethyl propanol (AMP-95), sodium hydroxide, ammonium hydroxide, aminomethylpropanediol, tromethamine, tetrahydroxypropylethylenediamine, amino acids, and the like. By using the neutralizing agent alone or in combination, it is possible to obtain a composition having an optimum transparency and a thickening effect.

In addition, the composition of the present invention is a component commonly used in hair gels within the scope of the present invention as a component that can fix or styling hair, a polymer resin, an additive, a thickening agent, a neutralizing agent, and a moisturizing and conditioning effect. pH adjusters, fragrances, sunscreens, hair protectors, colorants and solvents such as water and ethanol can be used together.

The low molecular weight polyhydric alcohols used as moisturizers are not particularly limited in the present invention, but glycols, glycerins or polyhydric alcohols may be used, and preferred examples thereof include butylene glycol, glycerin, propylene glycol, diglycerine, triglycerine, Ethylene glycol, ethoxy diglycol, maltitol, sorbitol, or arbitrary mixtures thereof are mentioned, It is preferable to use 0.01-5.0% weight% of addition amount. If too little or too much amount is used, there is a concern that the effect of setting the hair and the viscosity, spreadability and stability of the product will be low.

Hair styling cosmetics according to the present invention exhibits a transparent to slightly opaque, the film formed is very high in strength, excellent in moisture resistance or water resistance under high humidity conditions and excellent in the ability to fix the hair. In addition, the drying time is shortened to reduce the styling time, there is an advantage that there is no flaking phenomenon.

Hereinafter, the present invention will be described in detail with reference to Examples.
