Description

Hair Conditioning Composition {COSMETIC COMPOSITIONS FOR HAIR CONDITIONING}

The present invention relates to a composition for hair conditioning, and more particularly, exhibits excellent hair conditioning effect, of course, does not require heating at the time of manufacture, and has a low viscosity (50 CP or less as measured by Brookfield viscometer at 25 ° C). , Preferably 20 to 50 CP) relates to a composition for convenient hair conditioning.

Consumers' preferences and needs for conditioning products that improve the appearance and feel of hair and make them easier to care for are increasing day by day. These products are particularly necessary for the treatment of hair damaged by dyeing, perm and combing. Damaged hair, when wet or dry, has severe hair stiffness and stiffness and is difficult to manage due to lack of gloss and has a poor appearance.

Therefore, the hair conditioning compositions not only minimize the tangling and soften the hair in wet hair, but also prevent the hair from being blown by static electricity in dry hair, and improve the texture of the hair, making hair care easier and easier to see. To have a good appearance.

Hair conditioning products having such a function generally have an emulsion form, and in order to impart such a function, a cationic surfactant, a long-chain quaternary ammonium compound, a higher alcohol, and a silicone and a moisturizing agent are generally the main components. It replenishes the hair's oil after shampooing, giving the hair a conditioning effect.

Here, cationic surfactants are normally deposited on the hair by the interaction of cations and anions by supplying cationic surfactants to the surface of the net negatively charged hair in an aqueous composition with a neutral pH value to prevent hair damage and static electricity generation. In addition, it is used to provide the softness of the hair after rinsing and drying, and to reduce the tangling.

In addition, silicone is used to artificially give sebum-like feel to reduce the stiffness of hair due to the removal of sebum after shampooing, to give softness and shine to dry hair.

Existing conditioners, which have a function suitable for rinsing compositions, ie, hair, which are then left in place for a suitable period of time and then rinsed with water, have been formulated with O / W (oil-in-water) or W / O (water-in-water). in-Oil) type of emulsion, which not only limits the formulation and use of the product, but also requires a lot of time in preparation, requires a heating process, and entails manufacturing difficulties due to high viscosity. Had a disadvantage.

In general, silicone oil and polymer silicone (gum) give gloss and flexibility to the hair and provide softness to the hair after drying. However, in spite of these excellent properties, silicone is limited in its utilization due to lack of moisturizing properties and poor compatibility with other ingredients, and it accumulates in the hair and degrades the softness of hair after long-term use, and recontamination by dust and sebum There is a problem that accelerates. In addition, there is also a problem of reducing the smoothness of the hair during rinsing, and increase the tangling.

The present invention relates to hair protective cosmetics, in particular cosmetic compositions, preferably rinsing compositions which provide improved hair conditioning properties, ie compositions suitable for rinsing with water after being added to the hair and then left for a suitable time.

The hair conditioner composition according to the present invention exhibits excellent hair conditioning effect compared to the conventional conditioner in the form of an emulsion, and does not require manufacturing heat treatment and has a low viscosity (50 when measured with a Brookfield viscometer at 25 ° C.). It is below CP, preferably 20-50 CP), which not only facilitates the manufacture, but also provides the advantage of providing a conditioner for spray and mousse formulations as it is in liquid form.

Accordingly, it is an object of the present invention to provide a hair conditioning lotion for rinsing after application to hair.

It is another object of the present invention to provide a hair protection composition which improves the feel of hair in both wet and dry conditions and has aesthetic appearance.

Yet another object of the present invention is to provide a composition which can be easily applied to hair because it is a liquid having a low viscosity.

It is a further object of the present invention to provide a hair protection composition which exhibits an excellent hair conditioning effect compared to products in the conventional emulsion form.

It is a further object of the present invention to provide a method for improving the manufacturing difficulties due to the heating or high viscosity which is inevitably involved in the production of products in the form of conventional emulsions in the form of liquid solutions.

Still another object of the present invention is to provide a composition that exhibits a better conditioning effect without using a nonvolatile silicone oil that has been generally used in conventional hair protection conditioners.

The present invention does not use non-volatile silicone oil and polymer silicone (gum) generally used in existing conditioners, thereby minimizing hair entanglement during rinsing and improving softness after drying.

In addition, the present invention is in the form of a hair conditioner in the form of a solution in which fatty substances and cationic surfactants are dissolved in alcohols and glycols, unlike conventional emulsion-type conditioners, superior to conventional emulsion-type hair conditioners. In addition to providing an effect, the present invention provides the advantages of time in manufacturing and convenience in the manufacturing process, and also enables the manufacture of a conditioner in the form of a spray or a mousse as a liquid.

The present invention provides an aqueous liquid hair cosmetic composition having excellent hair conditioning effect and reducing tangling in the wet state, comprising: (a) at least one organic solvent or polymer thereof selected from polyalcohols having two or more hydroxy; 90% by weight, (b) 0.1 to 90% by weight of one or more lower alcohols or polar organic solvents having one hydroxy having 6 or less carbon atoms, (c) 0.1 to 1 or more fatty alcohols having carbon in the range of C ₁₂ to C ₂₂ 20% by weight, (d) 0.1-20% by weight of one or more cationic surfactants selected from quaternary ammonium salts, and (e) the balance consists of water, characterized in that the pH range is 3-8.
