Description

Hair conditioning composition {HAIR CONDITIONING COMPOSITION}

The present invention relates to a hair conditioning composition, and more particularly to a hair conditioning composition comprising a silicone acrylate film former and dimethicone having an average molecular weight of 80,000 to 1,100,000 g / mol as an active ingredient.

In general, products that impart conditioning (improved hair condition) to the hair can be divided into a washable product and a non-washed product. The products to be washed can be divided into hair rinses, hair treatments, hair packs, hair masks and hair ampoules. It is mainly composed of emulsifier type quaternary cationic surfactants and small amount of silicone oil or conditioning components such as synthetic oils and natural oils. Gives hair shine and smoothness.

In the case of non-washed products, it can be classified into hair mists, hair essences, hair serum, hair oil, etc., and various kinds of formulations give a conditioning effect to the hair.

Silicone oils used in non-washed hair conditioning compositions have a variety of functions depending on their type and molecular weight, and thus, even if they have the same chemical structure, their sensory characteristics may vary. Silicone has various forms depending on the molecular weight and viscosity. In the volatile form with the lowest molecular weight and viscosity, the form of liquid, viscous liquid, gum, gel, elastomer and resin takes order in increasing molecular weight and viscosity. That is, as the molecular weight of silicon increases, the viscosity also increases.

Conventional conventional hair conditioning products contain an excess of silicone oil in order to increase the retention time of the efficacy and in this case can impart instant gloss and smoothness to the hair when used, There is a problem that it is possible to induce abuse in

Hereinafter, the present invention will be described in detail.

The names of the compounds referred to herein are to be understood as meaning the International Nomenclature Cosmetic (INCI) listed on the International Cosmetic Ingredient Dictionary (ICID) issued by the Cosmetic, Toiletry and Fragrance Association (CTFA) Ingredient Name means a compound according to the IUPAC nomenclature established by the International Union of Pure and Applied Chemistry (IUPAC) if the name does not exist in INCI Name, and IUPAC If no compound according to the nomenclature is present, it refers to a compound corresponding to the name of the compound commonly used in the technical field of the present invention.

The hair conditioning composition according to the present invention may contain a silicone acrylate film former and dimethiconol as an active ingredient and may be embodied as a transparent oil formulation.

The silicone acrylate film former is a film-forming agent such as a silicone acrylate copolymer. The silicone acrylate film former is contained in an amount of 0.1 to 4% by weight based on the total weight of the hair conditioning composition, , And may be contained in an amount of preferably 0.1 to 2% by weight. If the content of the silicone acrylate film former is less than 0.1% by weight, the effect of the curl sustaining force of the hair can not be expected. If the content is more than 4% by weight, a stiff film is formed, have.

In one embodiment of the present invention, Dimethicol is a dimethicol having an average molecular weight of 800,000 to 1,100,000 g / mol, and may have a viscosity range of 7,7000 to 140,000 cs.

In addition, the dimethicone may be contained in an amount of 1 to 20% by weight, preferably 5 to 15% by weight, based on the total weight of the hair conditioning composition for the intended effect. If the content of Dimethicol is less than 1% by weight, the effect of hair conditioning is difficult to expect. If the content of dimethicol exceeds 20% by weight, a feeling of use and sticky feel appears and uniform application to hair is difficult.

On the other hand, the dimethicol and the silicone acrylate film former may be blended in a weight ratio of 10: 1 to 100: 1 in order to achieve the desired effect.
