Description

Hair Conditioning Composition {HAIR CONDITIONING COMPOSITION}

The present invention relates to a hair conditioning composition, and more particularly, to a hair conditioning composition having excellent usability and conditioning effect by containing a volatile silicone oil and a nonvolatile silicone oil.

In general, products that give the hair a feeling of conditioning (improvement of hair condition) can be divided into products that are washed out and products that are not washed out. In case of washing product, it can be classified into hair rinse, hair treatment, hair pack, hair mask, hair ampoule, etc.It is mainly composed of emulsifier type quaternary cationic surfactant and small amount of silicone oil or conditioning ingredients such as synthetic and natural oils. Gives hair shine and smoothness.

Products that do not wash off can be classified into hair mist, hair essence, hair serum, hair oil, etc., and give various effects to hair conditioner.

Silicone oils used in non-washable hair conditioning compositions have various functions depending on their type and molecular weight, and thus, even if the silicone oils have the same chemical structure, their usability characteristics may vary. Silicones come in a variety of forms depending on molecular weight and viscosity, in the form of liquids, viscous liquids, gums, gels, elastomers and resins in the order of increasing molecular weight and viscosity in the volatile forms having the lowest molecular weight and viscosity. In other words, as the molecular weight of silicon increases, the viscosity also increases.

Among the non-washable products, especially hair serum is a formulation that disperses excess silicone oil, which can immediately give gloss and smoothness when used on hair, but stickiness on use due to excess silicone oil, stiffness in hair, etc. There was a problem that has a disadvantage.

In one embodiment of the present invention, the nonvolatile silicone oil may have a viscosity of 10 million to 50 million cs.

In one embodiment of the present invention, the nonvolatile silicone oil is made of polydimethylsiloxane, phenylsiloxane, alkylmethyl siloxane, dimethicone, cyclomethicone, dimethiconol, dimethicone copolyol, silicone elastomer, and silicone resin It may be any one or more selected from the group.

In one embodiment of the present invention, the volatile silicone oil may be 50 to 90% by weight based on the total weight of the composition.

In one embodiment of the present invention, the nonvolatile silicone oil may be contained in 10 to 50% by weight based on the total weight of the composition.

In one embodiment of the present invention, the composition may contain a nonvolatile silicone oil and volatile silicone oil in a ratio of 1: 1 to 1:30.

In one embodiment of the present invention, the composition may contain 60 to 99.9% by weight of the total weight of the composition of the volatile silicone oil and non-volatile silicone oil.

The hair conditioning composition of the present invention is a composition that can be applied directly to the hair without being washed out, which immediately gives the hair gloss and smoothness, and is less sticky, resulting in a fresh and smooth application.

Hereinafter, preferred embodiments of the present invention will be described in detail in order to facilitate the present invention by those skilled in the art.

The present invention provides hair conditioning compositions containing volatile silicone oils and nonvolatile silicone oils.

The hair conditioning composition of the present invention is based on silicone oil and is characterized by simultaneously containing volatile silicone oil and nonvolatile silicone oil in various types of silicone oil.

Silicone oil is a representative conditioning ingredient with light, smooth properties that are colorless, transparent and almost odorless. Because of these properties, silicone oils are very versatile in their use in cosmetic compositions as well as in various hair related products. In general, silicone oils are divided into volatile and nonvolatile silicone oils, depending on their characteristics. This classification is determined by the molecular weight of the silicone oil and the viscosity of the silicone oil is determined by the type and proportion of the organic groups bonded to silicon and the degree of polymerization.

The volatile silicone oil used in the present invention is not limited as long as it is volatile, but preferably has a viscosity of 0.5 to 5 cs, more preferably 0.65 to 5 cs, and most preferably 0.65 cs.

The volatile silicone oil may be any one or more of a linear polysiloxane oil or a cyclic polysiloxane oil having a viscosity of 0.5 to 5 cs, but is not limited thereto. In the present invention, for example, the straight chain polysiloxane may be methyl polysiloxane, ethyl polysiloxane, and the cyclic polysiloxane may be phenyl polysiloxane, methylphenylpolysiloxane, methyl cyclo polysiloxane.

Non-volatile silicone oil used in the present invention is not limited as long as it is non-volatile, the viscosity is preferably 10 million to 50 million cs, more preferably 20 million to 40 million cs, most preferably 20 million cs Can be.

The nonvolatile silicone oil is composed of polydimethylsiloxane, phenylsiloxane, alkylmethyl siloxane, dimethicone, cyclomethicone, dimethiconol, dimethicone copolyol, silicone elastomer, and silicone resin having a viscosity of 10 to 50 million cs. It may be any one or more selected from the group, but is not limited thereto. Preferably, any one or more selected from the group consisting of dimethicone, cyclomethicone and dimethiconol may be used as the nonvolatile silicone oil, and two or more compounds may be mixed and used. Dimethiconol and dimethicone copolyone have high polarity and compatibility since they have a hydrophilic hydroxyl group outside the compound, unlike dimethicone having only a methyl group.

The ratio of volatile silicone oil and nonvolatile silicone oil may vary depending on the degree of hair gloss and smoothness, but the composition may contain 1: 1 to 1:30 ratio of nonvolatile silicone oil and volatile silicone oil. desirable. If the ratio is 1: 1 or less within the range of the ratio, the residual feeling due to non-volatile silicone is likely to remain sticky, and if it is 1:30 or greater, it is difficult to give a smooth feeling to the hair.

In addition, the volatile silicone oil is preferably contained 50 to 90% by weight, more preferably 70 to 90% by weight relative to the total weight of the composition. If the volatile silicone oil is less than 50% by weight it is difficult to obtain a sufficiently fresh feeling, and if it is more than 90% by weight it is difficult to give a smooth feeling to the hair.

The nonvolatile silicone oil may be contained in an amount of 10 to 50% by weight, more preferably 10 to 20% by weight, and most preferably 15% by weight, based on the total weight of the composition. If the nonvolatile silicone oil is less than 10% by weight, the softening effect of the hair is inferior, and if it is more than 50% by weight, a wet feeling appears.

The hair conditioning composition of the present invention contains 60 to 99.9% by weight, preferably 90% by weight or more, more preferably 95% by weight or more, of the volatile silicone oil and the nonvolatile silicone oil, based on the total weight of the composition. Contains silicone oil as a main ingredient. If the total amount of the silicone oil is less than 60% by weight, it is preferable to use it in the above range because the gloss and smoothness are not significantly enhanced.

The hair conditioning composition according to the present invention contains a large amount of volatile silicone oil and non-volatile silicone oil in an anhydrous form containing little water, thereby providing a shine and smoothness to the hair instantly as a composition which can be applied directly to the hair without being washed off. At the same time, there is little stickiness, and it has an excellent usability by refreshing and smooth application. Thus, when used for damaged hair, a particularly good and immediate conditioning effect can be obtained.

The composition according to the invention may not be washed off after being applied to the hair, or may be washed off. Moreover, it is also possible to mix and use with a conventional hair composition.

The hair conditioning composition of the present invention is not particularly limited in formulating, but is formulated as hair tonic, hair nourishing longevity, scalp treatment, hair treatment, hair rinse, hair shampoo, hair lotion or scalp hair treatment, etc. Can be.

In addition, in the respective formulations, the ingredients other than the above-mentioned essential ingredients can be suitably selected and blended by those skilled in the art depending on the kind of the external preparation, the purpose of use, and the like. That is, the components commonly used in existing products can be added and used within a range that does not impair the effects of the present invention. For example, oils, fragrances, thickeners, dispersants, solubilizers, surfactants and the like may be used, but are not particularly limited depending on the purpose.

The present invention is described in more detail through the following implementation. However, the examples are for illustrating the present invention, and the scope of the present invention is not limited thereto.
