Description

Technical Field

[0001] The present invention relates to a hair conditioning composition.

Background Art

[0002] In daily hair care, hair cosmetics such as rinses, conditioners, and treatments are widely used to improve the feel of hair after shampooing.

[0003] Regarding these hair cosmetics such as rinses, conditioners, and treatments, various proposals have been made according to the desired hair feel of the user. However, although they can meet the market requirements for the feeling of smoothness after drying or the feeling of moistness after drying, the feeling of residue during rinsing and the feeling of smoothness during drying are often overlooked.

[0004] For example, in order to impart conditioning properties during rinsing, hair cosmetics containing organopolysiloxane and branched fatty acids have been proposed (Patent Document 1). However, in these conditioning compositions, while they can impart conditioning properties during rinsing, they were not satisfactory in terms of the feeling of smoothness during drying.

[0005] Also, for the feeling of smoothness after drying, conditioning compositions containing dimer acid etc. have been proposed (Patent Document 2). However, in these conditioning compositions, while they can impart the feeling of smoothness and moistness after drying, they were not satisfactory in terms of the feeling of residue during rinsing and the feeling of smoothness during drying.

[0007] The present invention has been made in view of the above circumstances, and its purpose is to provide a hair conditioning composition that provides a lingering feeling when rinsing while also providing a smooth feeling when blow-drying. [Means for solving the problem]

[0008] The inventors, through diligent research to achieve the objectives of the present invention, discovered that by including an unneutralized (A) tertiary amine, a hair conditioning composition can be obtained that combines a pleasant feeling when rinsing, a smooth feeling when blow-drying, and a smooth feeling after drying, thus completing the present invention.

[0009] The present invention is a hair conditioning composition characterized by having an unneutralized (A). (A) Tertiary amine

[0010] Preferably, the hair conditioning composition according to claim 1 is such that the unneutralized (A) is present in an amount of 0.01% to 15% of the total mass.

[0011] More preferably, the hair conditioning composition according to claim 1 or 2 contains (B). (B) Silicone compounds that do not contain amino groups

[0012] More preferably, the hair conditioning composition is as described in any one of claims 1 to 3, wherein (B) / unneutralized (A) is 0.5 to 50. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a hair conditioning composition that provides a lingering feeling when rinsing, a smooth feeling when blow-drying, and a smooth feeling even after drying. [Modes for carrying out the invention]

[0014] The present invention will be described in detail below.

[0015] In this specification, "lingering feeling" refers to a state in which the surface of the hair is uniform when the hair is pinched and moved between the fingers, and a thickness derived from the product can be felt on the hair surface. "Smooth feeling" refers to a state in which the hair moves smoothly without snagging when the hair is pinched and moved between the fingers, and the surface of the hair is uniformly coated.

[0016] <Hair Conditioning Composition> The conditioning composition of the present invention can be used in hair rinses, hair conditioners, hair treatments, hair packs, hair creams, leave-on treatments, etc. Furthermore, the conditioning composition of the present invention can be manufactured by conventional methods, and its dosage form is not particularly limited. Specifically, it can be used in appropriate dosage forms such as cream or emulsion. It can also be in aerosol or non-aerosol form, and in the case of non-aerosol, it can take various forms such as squeeze-former and pump-former types.

[0017] The hair conditioning composition of the present invention is characterized by having an unneutralized (A) tertiary amine, and preferably the above hair conditioning composition in which the unneutralized (A) is present in an amount of 0.01% to 15% of the total mass.

[0018] More preferably, the hair conditioning composition contains (B) a silicone compound that does not have an amino group, and it is even more preferable that the ratio of (B) to unneutralized (A) is 0.5 to 50. The following describes in detail each component of the conditioning composition of the present invention.

[0019] <Component (A)> The component (A) used in the hair conditioning composition of the present invention is a tertiary amine and needs to be present in the hair conditioning composition in an unneutralized state. Here, being unneutralized means a state where the tertiary amine is not quaternized by an acid such as lactic acid. It is assumed that 1 mol of a monovalent tertiary amine is neutralized by 1 mol of a monovalent acid. Since the component (A) is not neutralized, the component (A) exists in the system in a state having an unshared electron pair that is less affected by the electronegativity of other substances. Therefore, in addition to the smooth feeling during drying and the smooth feeling after drying, a residual feeling during hair rinsing can be produced.

[0020] Examples of the component (A) include tertiary amines represented by the formula (1). [Chemical formula] (At least one of R5, R6, and R7 has an alkyl group having 12 to 30 carbon atoms, may contain an amide group, a hydroxy group, or an alkylene glycol group, and the remainder is independently selected from an alkyl group having 1 to 3 carbon atoms or an alkylene glycol group.)

[0021] The tertiary amine used as the unneutralized component (A) is not particularly limited, but specifically, stearamidopropyldimethylamine, behenamidopropyldimethylamine, (PEG-1 / PPG-1) stearamine, (PEG-1 / PPG-1) behenamine, etc. may be mentioned. Commercially available products may be used as the component (A).

[0022] The unneutralized component (A) is not particularly limited as long as the effects of the present invention can be exhibited, but the blending amount is preferably such that the total amount of the unneutralized component (A) is 0.01% to 15% by mass with respect to the hair conditioning composition. If the blending amount is 0.01% to 15% by mass in total, the residual feeling during hair rinsing will be even better.

[0023] <(B) component> Component (B) used in the hair conditioning composition of the present invention is a silicone compound that does not have an amino group. Silicone compounds are a general term for compounds that have a siloxane bond. Component (B) is mainly used as an ingredient that contributes to the smooth feeling of hair when blow-drying.

[0024] (B) The silicone compounds that do not have an amino group and can be used as component (B) are not limited to these, but specifically include dimethicone, (divinyldimethicone / dimethicone) copolymer, phenyltrimethicone, etc., and one or more of these can be used in combination. Component (B) may be a commercially available product.

[0025] The amount of component (B) is not particularly limited as long as it can exert the effects of the present invention, but it is preferably 0.1% to 10% by mass relative to the hair conditioning composition. If the amount is 0.1% or more and 10% or less by mass, the smooth feeling when using a hair dryer will be even better.

[0026] Furthermore, (B) / unneutralized (A) is not particularly limited as long as it can exert the effects of the present invention, but if the amount added is 0.5 to 50 of the conditioning composition, the smooth feeling after drying will be even better.

[0027] Therefore, by combining the above-mentioned specific component (A) and component (B), the hair conditioning composition of the present invention exhibits an effect that combines a lingering feeling when rinsing, a smooth feeling when blow-drying, and a smooth feeling after drying.

[0028] <Other ingredients> In addition to the above-mentioned components, the hair conditioning composition of the present invention may also contain other components commonly used in hair conditioning compositions, as long as they do not impair the effects of the present invention.

[0029] Such ingredients include, for example, higher alcohols such as stearyl alcohol and behenyl alcohol; quaternary ammonium salts such as steartrimonium chloride and behentrimonium chloride; high molecular weight compounds such as cationized cellulose and poly(diallyldimethylammonium chloride); anti-dandruff ingredients such as zinc pyrithione and benzalkonium chloride; lower alcohols such as ethanol, methanol, propyl alcohol, and isopropyl alcohol; polyols such as DPG and propylene glycol; and other ingredients such as UV absorbers, preservatives, sugars, fragrances, colorants, metal ion sequestering agents, antioxidants, various chemicals, and water. [Examples]

[0030] Next, the hair conditioning composition of the present invention will be specifically described by illustrating examples and comparative examples, but the present invention is not limited in any way by these examples. First, the test methods and evaluation methods used in each example will be described.

[0031] (1) Method for evaluating the feeling of residue after rinsing 3g of the conditioning composition according to the examples and comparative examples of the present invention, prepared by conventional methods using the formulations shown in Tables 1-3, was applied to a 10g hair bundle (Beaulux Co., Ltd., same Asian human hair, 30cm in length). Ten trained evaluators evaluated the lingering sensation felt during rinsing with 40°C water for 10 seconds, according to the evaluation criteria below. The score before treatment was set to 5 points, and the average of the scores of the 10 evaluators was calculated based on the difference in scores after three treatments. The lingering sensation during rinsing was determined using this average value based on the scoring criteria below.

[0032] <Evaluation criteria for residue after rinsing> 5 points: When pinched and pulled, the surface felt uniform, and the product felt thick on the hair surface. 4 points: When pinched and pulled, the surface was uniform, and the product could be felt on the surface of the hair. 3 points: When pinched and pulled, the surface was not uniform, but the product could be felt on the surface of the hair. Points 2: When pinched and pulled, the surface was not uniform, and I didn't feel much of the product on the hair surface. 1 point: When pinched and pulled, the surface was not uniform, and I couldn't feel any product on the surface of the hair at all.

[0033] <Score criteria for residue after rinsing> ◎: Excellent ··· 4.5 points or higher ○: Excellent...3 points or more, less than 4.5 points △: Inferior ····2.0 or higher, less than 3 points ×: Very poor... Less than 2.0 points

[0034] (2) Method for evaluating the smoothness of hair when using a hair dryer Three g of the conditioning compositions according to the examples and comparative examples of the present invention, prepared by conventional methods using the formulations shown in Tables 1-3, were applied to a 10 g hair bundle (Beaulux Co., Ltd., same Asian human hair, 30 cm in length). After rinsing with 40°C water for 10 seconds, the wet hair bundle was combed 20 times, and after towel-drying for 5 seconds, 10 trained evaluators observed and evaluated the smoothness of the hair while it was drying with a hairdryer, according to the evaluation criteria below. The average of the sum of the scores from the 10 evaluators was calculated. Using this average value, the smoothness during drying was determined based on the scoring criteria below.

[0035] <Evaluation Criteria for Smoothness During Hair Drying> 5 points: When I pinched and pulled it, there was absolutely no snagging, and the surface of the hair felt evenly coated. 4 points: When pinched and pulled, there was no snagging, and the hair surface felt like it was coated fairly evenly. 3 points: When pinched and pulled, there was not much snagging, and the surface of the hair felt like it was coated fairly evenly. Points 2: There wasn't much resistance when pinching and pulling, but the hair surface didn't feel like it was coated. 1 point: When I pinched and pulled it, I felt some resistance, but it didn't feel like the surface of the hair was coated.

[0036] <Smoothness during blow-drying: scoring criteria> ◎: Excellent ··· 4.5 points or higher ○: Excellent...3 points or more, less than 4.5 points △: Inferior ····2.0 or higher, less than 3 points ×: Very poor... Less than 2.0 points

[0037] (3) Method for evaluating the smoothness after drying 3g of the conditioning composition according to the examples and comparative examples of the present invention, prepared by conventional methods using the formulations shown in Tables 1-3, was applied to a 10g hair bundle (Beaulux Co., Ltd., same Asian human hair, 30cm in length). After rinsing with 40°C water for 10 seconds, the wet hair bundle was combed 20 times, towel-dried for 5 seconds, and then dried with a hairdryer until completely dry. Ten trained evaluators evaluated the smoothness of the hair according to the evaluation criteria below, and the average of the sum of the scores from the ten evaluators was calculated. The smoothness after drying was determined based on the scoring criteria below using this average value.

[0038] <Evaluation Criteria for Smoothness After Drying> 5 points: When I pinched and pulled it, there was absolutely no snagging, and the surface of the hair felt evenly coated. 4 points: When pinched and pulled, there was no snagging, and the hair surface felt like it was coated fairly evenly. 3 points: When pinched and pulled, there was not much snagging, and the surface of the hair felt like it was coated fairly evenly. Points 2: There wasn't much resistance when pinching and pulling, but the hair surface didn't feel like it was coated. 1 point: When I pinched and pulled it, I felt some resistance, but it didn't feel like the surface of the hair was coated.

[0039] <Smoothness after drying: scoring criteria> ◎: Excellent ··· 4.5 points or higher ○: Excellent...3 points or more, less than 4.5 points △: Inferior ····2.0 or higher, less than 3 points ×: Very poor... Less than 2.0 points
