Description

[Technical field]

[0001] The present invention relates to a hair conditioning composition that has good finger smoothness and moist feeling even without containing an amino-modified silicone, and can impart a bouncy feel to hair without impairing the hair conditioning effect. [Background technology]

[0002] In recent years, with the diversification of hairstyles, consumers have begun to regularly perform hair coloring and perm treatments to obtain the desired appearance of their hair. However, when hair coloring or perm treatments are performed, the chemicals used can cause the lipid layer on the surface of the hair to be lost, resulting in phenomena such as a decrease in finger slippage, a squeaky feeling, and poor manageability, and furthermore, problems such as the leakage of interstitial matter from the inside of the hair, resulting in a decrease in the firmness and strength of the hair can occur.

[0003] In addition, daily brushing and combing also scrapes off the cuticle, increasing friction and causing dryness and poor slipperiness. Furthermore, the loss of hair firmness due to aging and other factors is often a problem. For this reason, hair rinses and hair conditioning compositions are required to provide not only higher conditioning effects such as smoothness and moisturizing, but also firmness and stiffness.

[0004] In recent years, there has been an increase in hair conditioning compositions that contain amino-modified silicones, which are excellent in providing a moist feeling, softness, smoothness to the fingers, etc. Since amino-modified silicones have a cationized amino group, they have a higher adsorption power to hair than dimethicone, and can be expected to provide a long-lasting conditioning effect.

[0005] On the other hand, excessive use of amino-modified silicone can make hair sticky or slimy, and it has a high affinity and coating power for hair, which can make it difficult for colorants to penetrate and makes it difficult to perm. In addition, regular long-term use can make hair heavy and reduce the sense of elasticity.

[0006] A technology that can give hair a bouncy feel has been disclosed (Patent Document 1), but it does not improve the moist feeling, and since it contains amino-modified silicone, it may be difficult to feel the bouncy feel when used for a long time. Another technology that can give hair a moist feeling has been disclosed (Patent Document 2), but it does not improve the bouncy feel, and since it also contains amino-modified silicone, there is a concern that the bouncy feel will decrease when used for a long time.

Effect of the Invention

[0013] The hair conditioning composition of the present invention has good finger smoothness and moist feeling even though it does not contain an amino-modified silicone, and is excellent in imparting a bouncy and stiff feel to hair without impairing the hair conditioning effect. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The present invention is a commonly used hair conditioning composition that contains 0.5 to 4% by weight of a cationic surfactant and a higher alcohol having 16 to 22 carbon atoms, with the weight ratio of (higher alcohol having 16 to 22 carbon atoms) / (cationic surfactant) being in the range of 1 to 3.

[0015] In the present invention, the component (A) of the oil agent that is liquid at 25°C, excluding silicone oil, includes, for example, hydrocarbon oils such as liquid paraffin, hydrogenated polyisobutene, squalane, triglycerides such as olive oil and macadamia nut oil, ester oils such as octyldodecyl myristate and isononyl isononanoate, and branched or unsaturated higher alcohols such as isostearyl alcohol and oleyl alcohol. These liquid oils may be contained alone or in combination, and among them, from the viewpoint of moist feeling and stability over time, hydrocarbon oils such as liquid paraffin, hydrogenated polyisobutene, and squalane are preferred. In addition, the liquid state in the present invention means that the liquid state has fluidity at 25°C.

[0016] The content of component (A) is not particularly limited, but is preferably 0.05 to 4% by weight based on the total weight of the hair conditioning composition.

[0017] The cationic guar gum used in the present invention as component (B) is, for example, guar hydroxypropyltrimonium chloride, which is guar gum converted to a quaternary ammonium salt. Commercially available products include, for example, "Labor Gum CG-M" (manufactured by DSP Gokyo Food & Chemical Co., Ltd.).

[0018] The content of the component (B), cationic guar gum, is not particularly limited, but is preferably 0.05 to 2% by weight based on the total weight of the hair conditioning composition.

[0019] The component (C) Polyquaternium-48 in the present invention is a polymer of a quaternary ammonium salt consisting of ethyl methacrylate betaine, 2-hydroxyethyl methacrylate, and ethyl methacrylate trimethylammonium chloride. Commercially available products include "Plussize L-450W" (manufactured by GOO Chemical Industry Co., Ltd.). (Polyquaternium-48: 40%)

[0020] The content of component (C) polyquaternium-48 is preferably 0.5 to 3% by weight, more preferably 1 to 2% by weight. If the content is less than 0.5% by weight, sufficient firmness cannot be obtained, which is not preferable. On the other hand, if the content exceeds 3% by weight, it may be felt as stickiness or an unpleasant squeaking sensation rather than firmness, and it may be difficult to obtain a smooth feel.

[0021] The component (D) in the present invention has a kinetic viscosity of 10,000 mm at 25°C. 2 Examples of highly polymerized silicones having a viscosity of 100 / s or more and no amino group (hereinafter referred to as "highly polymerized silicones") include one or more compounds selected from the group consisting of highly polymerized dimethicones having no amino group, highly polymerized dimethiconols having no amino group, and polymers having dimethicone as a part of the monomer. Commercially available products include "Silicone KF96H / 100,000 CS" (manufactured by Shin-Etsu Chemical Co., Ltd.), "Silicone KF96H / 1,000,000 CS" (manufactured by Shin-Etsu Chemical Co., Ltd.), and "BELSIL GB 5150" (manufactured by Wacker Asahi Kasei Silicone Co., Ltd.) (highly polymerized methylpolysiloxane: 20%). Among them, from the viewpoint of finger sliding, the kinetic viscosity at 25°C is 50,000 to 300,000 mm 2 The kinematic viscosity in the present invention is preferably measured by the test method of JIS K2283.

[0022] Component (E) in the present invention has a kinetic viscosity of 500 mm at 25°C. 2Examples of low-viscosity silicones having a viscosity of 100 / s or less (hereinafter referred to as low-viscosity silicones) include low-viscosity dimethicones and low-viscosity methylphenyl polysiloxanes that do not have amino groups. Commercially available products include "SH200 C Fluid 30CS" (manufactured by Dow Toray Co., Ltd.), "Silicone KF-50-100CS" (manufactured by Shin-Etsu Chemical Co., Ltd.), and "SH200 C Fluid 350CS" (manufactured by Dow Toray Co., Ltd.). Among these, from the viewpoint of moisturizing feeling, those with a kinetic viscosity of 200 to 400 mm at 25°C are preferred. 2 / s is preferred.

[0023] The weight ratio (E) / (D) of component (D) to component (E) is preferably 1.5 to 2.1, more preferably 1.7 to 1.9. If the value of (E) / (D) is less than 1.5, it is not preferable because sufficient moist feeling may not be obtained. On the other hand, if it exceeds 2.1, it is not preferable because it may feel sticky.

[0024] The total content of components (D) and (E) in the present invention is not particularly limited, but is preferably from 2 to 5% by weight, more preferably from 3 to 4% by weight, based on the total weight of the hair conditioning composition.

[0025] The present invention may contain ingredients such as oils and fats, waxes, hydrocarbons, fatty acids, alcohols, esters, surfactants, pH adjusters, preservatives, fragrances, moisturizers, powders, ultraviolet absorbers, thickeners, pigments, antioxidants, chelating agents, and coating agents, which are used in cosmetics, quasi-drugs, medicines, foods, and the like, within the scope of the invention that does not impair the effects of the present invention.
