Description

(Hair setting agent composition with improved durability)

More particularly, the present invention relates to a stabilizer composition containing maltitol and dipropylene glycol together with a setting agent to improve the binding force and persistence between the hair.

Existing stabilizers are mostly cosmetic products that form a fixing force on hair using a polymer material, such as hair spray, mousse, gel and wax. As the polymer material, a setting agent such as pyrrolidone, acrylic acid, and acrylate may be used alone or in the form of a copolymer thereof. Such a polymer material may adhere to the hair through film formation after the solvent evaporates during the initial use, The film forms the desired style by forming the fixing force on the hair. Such a setting agent is disadvantageous in that its inherent film characteristics are lost under high temperature and high humidity conditions, and the fixing force in the hair is deteriorated over time. As a solution to this problem, the present inventors have tried to solve the problem of deterioration of fixation force by copolymerization with monomers having excellent moisture resistance in the above polymer materials. Polypyrrolidone / vinyl acetate copolymer is a typical setting agent with excellent moisture resistance obtained through these studies. Luviskol VA64 from BASF is commercially available. However, the above copolymers do not exhibit satisfactory performance.

Accordingly, the present inventors have made efforts to develop a composition for improving the cohesion and persistence of hair, and as a result, found that the use of maltitol and dipropylene glycol together with a setting agent enhances the binding force between the hair and improves the persistence of the setting agent And completed the present invention.

Accordingly, it is an object of the present invention to provide a composition for orthotics which enhances the binding force between the hair and improves the setting agent.

In order to achieve the above object, the present invention provides a cleaning agent composition containing a setting agent, maltitol and dipropylene glycol as an active ingredient.

The composition of the present invention improves the binding force between the setting agent and the hair and improves the durability of the setting agent, so that it has excellent ability to continuously maintain styling after application to the hair.

The present invention provides a regular-charge formulation composition comprising 0.1 to 20% by weight of maltitol, 0.1 to 20% by weight of dipropylene glycol and 0.1 to 20% by weight of a setting agent, and further comprising residual ethanol or water as a solvent.

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

The term " correcting agent " used in the present invention means a cosmetic finish for hair which is used when the hair is finished in an attractive and beautiful style, and has the same meaning as "hair styling agent ".

The maltitol used as a binder in the present invention is a reducing sugar of sugar alcohols obtained by reducing maltose and is stable to heat, acid, and alkali to improve the moisture retention of food, and its structure is represented by the following formula (1)

Maltitol has the effect of improving the adhesion between hair. The content of maltitol is preferably 0.1 to 20% by weight based on the total weight of the composition. If the content of maltitol is less than 0.1% by weight, the composition may have a deterioration in its sustaining power. If the content of maltitol is more than 20% by weight, stickiness may increase and inconvenience may result.

The dipropylene glycol used in the present invention is a kind of polyol having three isomers represented by the following formula 2:

Dipropylene glycol improves the adhesive properties of a polymer material used as a setting agent and imparts an effect of improving moisture resistance upon film formation. The dipropylene glycol is preferably used in an amount of 0.1 to 20% by weight based on the total weight of the composition. If the content is less than 0.1% by weight, the durability of the composition may be weakened, and if it is more than 20% by weight, stickiness may increase, resulting in inconvenience in using the product.

It is also superior in styling durability compared to glycerin and propylene glycol, which are similar polyols used in orthostatic agents. That is, glycerin and propylene glycol did not have the desired styling durability.

The setting agent used in the present invention includes polyvinyl pyrrolidone, polyvinyl pyrrolidone / vinyl acetate copolymer, vinyl pyrrolidone / methacrylamide / vinyl imidazole copolymer, polyvinyl alcohol, polyethylene glycol, polyquaternium Acrylate / methacrylate copolymer, acrylate / octyl acrylamide copolymer, acrylate / t-butyl acrylamide copolymer and octyl acrylamide / acrylate / butylaminoethyl methacrylate These may be used singly or in combination of two or more.

Polyvinylpyrrolidone and polyvinylpyrrolidone / vinyl acetate copolymers are representative nonionic polymers that impart a strong setting power in hair styling products, while vinylpyrrolidone / methacrylamide / vinylimidazole copolymers are vinylpyridine Due to the rigid structure of ROLLIDON and VINYL IMIDAZOLE, it exhibits high setting power and durability, and it exhibits soft application property due to the flexible structure of methacrylamide in the middle. Polyvinyl alcohol and polyethylene glycol are water-soluble polymers, and methacryloylethyl betaine / acrylate copolymers are amphoteric polymers which give excellent setting power and durability in hair styling products, and acrylate / octyl acrylamide copolymer, Acrylate / t-butyl acrylamide copolymer and octyl acrylamide / acrylate / butylaminoethyl methacrylate are typical anionic setting agents having fast drying properties with strong setting power to hair. These setting agents are used to control the feeling of use and the strength of the style, and may be included in an amount of 0.1 to 30% by weight based on the total weight of the composition. If the content is less than 0.1% by weight, an effective setting power and a sustaining force are not exhibited. If the content is more than 30% by weight, the hair may be thickly applied to cause hair aggregation and flaking.

The detergent composition according to the present invention may contain water or ethanol as a solvent, and may further include at least one other additive selected from the group consisting of thickeners, conditioning agents, moisturizers, fragrances, preservatives and pigments. The above-mentioned ingredients are easily selected and usable by those skilled in the art as materials included in a conventional hair styling agent.

The composition of the present invention can be formulated with mousse, gel, spray or the like. In the case of a gel, a thickener can be used to make a desired viscosity, and it is also possible to use a pump, an aerosol, a cream or a tube. Mousse and spray can be produced by conventional methods using LPG gas to facilitate injection and suitable containers.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood, however, that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
