Description

Technical Field

[0001] The present invention relates to a cosmetic composition for improving hair without using silicone oil. Background Art

[0002] As modern lifestyles become more prevalent, external stimuli such as excessive combing, blow-drying, and frequent washing, or penetration of chemicals are aggravating the damage to the hair surface. Therefore, care products (e.g., shampoos, conditioners, hair lotions, hair treatments, etc.) that can prevent hair damage, protect hair quality, and provide excellent gloss and combing properties are on the rise.

[0003] Silicone oil has a high molecular weight, has little viscosity change due to temperature changes, is light and smooth, and can add continuous gloss and shine when used on hair, etc. Therefore, it has been used as a cleaning agent and cosmetic raw material.

[0004] However, as research results have pointed out that silicone oil is an environmental pollutant that is harmful to biodiversity, Europe has banned the use of silicone oil in cleaning products, and the world is showing a trend of restricting the use of silicone oil. In addition, when silicone ingredients are used in hair products, the problem of silicone ingredients clogging pores will occur. When silicone oil is used for a long time, the pores with active sebum secretion will be blocked, making it impossible for sebum to be discharged normally, which will lead to the onset of scalp inflammation, such as folliculitis.

[0026] Figure 1 The anti-frizz effect achieved after applying the cosmetic compositions in the examples and comparative examples of the present invention to the hair is shown.

[0027] * Reference Numbers * DETAILED DESCRIPTION

[0028] The following is a detailed description of the embodiments of the present invention, but they are only used as examples and are not intended to limit the present invention, which can only be defined according to the scope of the following claims.

[0029] When describing the present invention, if it is considered that the detailed description of related well-known structures or functions will obscure the main points of the present invention, the detailed description thereof will be omitted.

[0030] When the inventor interprets the terms or words used in this specification and claims, they should not be limited to the usual or dictionary meanings, but should be interpreted based on the concept of properly defining the terms so as to describe the inventor's invention in the most optimal way, and into meanings and concepts that are consistent with the technical ideas of the present invention.

[0031] Furthermore, the embodiments and preparation examples described in the present invention represent only the most preferred embodiments of the present invention and do not represent the technical concept of the present invention. Therefore, it should be understood that when submitting this application, there are already multiple equivalents and modifications that can replace them.

[0032] Furthermore, in the present specification, “*” represents the same or different atoms or parts related to the chemical formula.

[0033] The hair-improving cosmetic composition of the present invention contains a lubricant and hydrocarbons, but does not contain silicone oil.

[0034] The cosmetic composition can be applied to the hair for use. Therefore, after applying the cosmetic composition, if the solvent has poor volatility, the hair will stick together and look heavy. Therefore, the cosmetic composition of the present invention contains hydrocarbon as a solvent with good volatility and strong solubility of the lubricant.

[0035] After the lubricant is evenly applied to the hair, the hydrocarbon should be volatilized. Therefore, preferably, the hydrocarbon is a straight chain or branched hydrocarbon with a carbon number of 6 to 30, and more preferably, a straight chain or branched hydrocarbon with a carbon number of 8 to 20. When the carbon number of the hydrocarbon is less than 6, the volatility of the hydrocarbon is too strong, and it is difficult to evenly apply the lubricant to the hair, and when the carbon number is more than 30, the hydrocarbon solvent cannot fully volatilize after being applied to the hair and remains on the hair, which makes the hair greasy and sticky. At this time, when the carbon number of the hydrocarbon is more than 8, the dissolution of the lubricant will be better, and when the carbon number of the hydrocarbon is less than 20, the volatility is more excellent, which can further improve the use feeling of the cosmetic composition.

[0036] For example, the hydrocarbon may include one or more selected from the group consisting of isododecane, undecane, isohexadecane, tridecane, isooctane, C10-11 isoparaffin, C10-12 isoparaffin, C10-13 isoparaffin, C11-12 isoparaffin, C11-13 isoparaffin, C11-14 isoparaffin, C12-14 isoparaffin, C12-14 isoparaffin, C11-12 isoparaffin, C11-13 isoparaffin, C11-14 ...1 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 isoparaffin, C11-11 is The present invention relates to a cosmetic composition comprising: a first hydrocarbon, a second hydrocarbon, and a third hydrocarbon. The first hydrocarbon is selected from the group consisting of isododecane, undecane, tridecane and C13-16 isoparaffin. For example, when isododecane is used among the first hydrocarbons, the cosmetic composition can present the softest feeling when used.

[0066] In the above Chemical Formulae 8 to 9, p is an integer of 1 to 10 respectively and independently; in the above Chemical Formula 9, q is an integer of 1 to 10.

[0067] The polyol derivative lubricant may be included in the lubricant and may be represented by the above chemical formulas 1 to 3. Specifically, for example, it may include one or more selected from the group consisting of propylene glycol diethylhexanoate, propylene glycol dipelargonate, tripentanoin, neopentyl glycol diheptanoate, neopentyl glycol dicaprate, neopentyl glycol dicaprylate, propylene glycol dicaprate, propylene glycol dicaprylate, propylene glycol diethylhexanoate, triethylhexanoin, caprylic triglyceride, capric triglyceride. triglyceride), capric triglyceride and PEG-7 caprylic / capric glyceride.

[0069] When the cosmetic composition of the present invention further comprises C12-15 alkyl benzoate as an additive, the hair care effect of the cosmetic composition is particularly excellent. Preferably, the specific content of C12-15 alkyl benzoate is 0.1 to 3.0% by weight in the total weight of the cosmetic composition. When the content of C12-15 alkyl benzoate is less than 0.1% by weight, the effect of C12-15 alkyl benzoate is very small. When the content exceeds 3.0% by weight, if used for hair care, the hair will be wet, greasy and sticky, and consumers will feel that the use feeling is not good.

[0070] The lubricant may contain only one of the polyol derivative lubricant or the carboxylic acid derivative lubricant, preferably, both are contained therein, specifically, the weight ratio of the polyol derivative lubricant to the carboxylic acid derivative lubricant is 1:35 to 35:1.

More preferably, the hydrocarbon comprises 60 to 85 weight % and the lubricant comprises 10 to 35 weight % of the total weight of the cosmetic composition.

[0072] The present invention is further described below by preparation examples and experimental examples. These examples are used to specifically describe the present invention, and the scope of the present invention is not limited by these examples.

[0073] [Preparation Example: Preparation of Cosmetic Composition]

[0074] The components described in the following Table 1 were mixed to prepare Examples 1 to 12, and for comparison, the components described in the following Table 2 were mixed to prepare Comparative Examples 1 to 6.

[0075]

[0076]

[0077]

[0078] [Experimental Example 1: Hair Care Effect Evaluation]

[0079] In order to evaluate the hair care effects of Comparative Examples 1 to 6 and Examples 1 to 12, experimental hair weighing 1.5 g and 100 mm in length was taken out, and the friction force was tested using a friction coefficient meter (Neo-Tribo (FCMS 170)). After Comparative Examples 1 to 6 and Examples 1 to 12 were evenly applied to the same hair and then dried, the friction force was tested using a friction coefficient meter (Neo-Tribo (FCMS 170)), and the results are recorded in the following Table 3.

[0080] The friction coefficient was tested repeatedly for 10 times in total and the average was calculated. The smaller the friction coefficient, the better the hair care effect.

[0081]

Table 3

[0082] Average friction coefficient Friction coefficient deviation Untreated group 0.353 0.010 Comparative Example 1 0.361 0.012 Comparative Example 2 0.334 0.006 Comparative Example 3 0.320 0.007 Comparative Example 4 0.308 0.013 Comparative Example 5 0.282 0.010 Comparative Example 6 0.242 0.013 Example 1 0.207 0.010 Example 2 0.132 0.007 Example 3 0.112 0.005 Example 4 0.104 0.004 Example 5 0.070 0.021 Example 6 0.076 0.033 Example 7 0.087 0.020 Example 8 0.089 0.024 Example 9 0.096 0.018 Example 10 0.091 0.011 Embodiment 11 0.076 0.004 Example 12 0.083 0.018

[0083] It was confirmed that the use of oils composed of hydrocarbons (Comparative Examples 4 to 6, Examples 1 to 12) is more effective in hair care than silicone oil (Comparative Example 1), mineral oil (Comparative Example 2) or ethanol (Comparative Example 3) which are commonly used to make hair smooth (soft). In addition, since ethanol or hydrocarbons have a low boiling point (BP) and a high volatility problem, a lubricant was used to remedy the problem. When hydrocarbons and lubricants are mixed at an appropriate ratio, the hair care effect is significantly excellent.

[0084] Comparative Example 4 and Example 2 confirmed that the lubricant is effective when it is kept at a certain amount or more. Examples 2 to 4 confirmed that when alkyl benzoate is included, the friction coefficient is smaller and the care effect is more effective. Examples 5 to 7 confirmed that when a carboxylic acid derivative lubricant is included, the hair care effect is more excellent than that of a polyol derivative lubricant.

[0085] [Experimental Example 2: Hair Growth Effect Evaluation]

[0086] In order to evaluate the hair growth effect, Comparative Examples 1 to 6 and Examples 1 to 12 were applied to experimental hair samples respectively and allowed to dry.

[0087] A certain light is irradiated onto the hair sample, and the gloss band on the hair surface due to scattered light is photographed. The captured image is then analyzed and evaluated.

[0088] The gloss band is extracted from the captured image using an analysis program, and the pixel value of the area occupied by the gloss band in the total area is calculated and recorded in Table 4 below.

[0089] The increase in the gloss band area indicates that the brightness has been improved.

[0090]

[0092] It was confirmed that Comparative Example 1 using silicone oil was more effective than the compositions of other comparative examples, and its effect was close to that of the composition of Example 2. However, the brightness of the composition of the example was better than that of the comparative example, which means that the hair growth effect of the example of the present invention was better than that of silicone oil even without using silicone oil.

[0093] [Experimental Example 3: Comparison and evaluation of the greasy feeling of hair]

[0094] In order to evaluate the greasy feeling, Comparative Examples 1 to 6 and Examples 1 to 12 were respectively applied to experimental hair samples and allowed to dry.

[0095] After leaving the mixture for 24 hours, the 10 groups were observed visually and evaluated according to the following evaluation criteria. The results are recorded in Table 5 below.

[0096] Evaluation Criteria

[0097] - Very sticky; 1. Slightly sticky; 2. Average; 3. Suitable; 4. Very suitable; 5. The lower the score, the oilier and stickier the hair.

[0098]

[0099] As shown in Table 5, the hair in Comparative Example 2 using only mineral oil was the greasiest, and silicone oil was conventionally used, and the results were good. Although silicone oil was not used in the compositions of the examples of the present invention, the feeling of use was similar to or appropriate to that of silicone oil.

[0100] [Experimental Example 4: Evaluation of dye retention]

[0101] In order to evaluate the retention of Comparative Examples 1 to 6 and Examples 1 to 12, the hair dyes were evenly applied to the experimental hair samples, left for 40 minutes, shampooed, rinsed with clean water, and blow-dried with a hair dryer.

[0102] After evenly applying Comparative Examples 1 to 6 and Examples 1 to 12 respectively on dry hair, ultraviolet rays were irradiated for 24 hours, and the color was measured using a colorimeter (Chromameter CM700).

[0103] The brightness values ​​detected by the colorimeter (Chromameter CM700) are recorded in Table 6 below, and the L* value is used as an index for comparison. At this time, L+ indicates brightness, L- indicates darkness, and the larger the L value, the brighter it is. The larger the ΔL (untreated value - treated value), the more serious the discoloration, and the smaller the value, the less color difference there is before and after the experiment, indicating that the color is well maintained.

[0106] (Unit: L*)

[0107] In terms of color retention after dyeing, the results shown by Comparative Examples 4 to 6 and Examples 1 to 12 composed of hydrocarbons and lubricants are better than the commonly used silicone oil (Comparative Example 1). In addition, in terms of color retention, the results shown by the compositions of the Examples are better than those of the Comparative Examples.

[0108] [Experimental Example 5: Evaluation of the smoothing effect on frizzy hair (Combining test)]

[0109] In order to evaluate the smoothing effect of frizzy hair, Comparative Examples 1 to 6 and Examples 1 to 12 were evenly applied to each test hair sample (back combing 5 times) and then dried.

[0110] The hair sample was combed until it was completely detangled, and the number of combings was measured and recorded in Table 7 below.

[0111] The less you comb your hair, the less frizzy it is.

[0112]

[0114] For combing frizzy hair, the application of the comparative or exemplary compositions is more effective than when untreated. The commonly used silicone oil (Comparative Example 1) produces better results than the other comparative compositions. Moreover, the exemplary compositions of the present invention, although not using silicone oil, show similar effects to silicone oil.

[0115] [Experimental example: Anti-Fizz evaluation]

[0116] In order to evaluate the anti-fizz properties of Comparative Examples 1 to 7 and Examples 1 to 11, the experimental hair was permed, dried naturally, and completely straightened with a straightening iron to prepare the experimental hair.

[0117] The compositions of the examples and comparative examples were evenly applied to the experimental hair samples and allowed to dry.

[0118] After being placed in an incubation tank at a temperature of 40° C. to 45° C. and a humidity of 50% to 60% for 36 hours, the condition of the hair was visually evaluated. Figure 1 Photos of individual hairs are shown.

[0119] The fewer curls there are, the better the anti-fizz effect is.

[0120] like Figure 1 As shown, the anti-fizz effect of the example composition is better than that of the comparative example composition.

[0121] It was visually observed that Comparative Example 1 or Comparative Example 2 (not shown) seemed to have excellent anti-fizz effect, but it was confirmed that the hair was frizzy, greasy and sticky.

[0122] The above content is only used to illustrate the present invention, and it should be understood that the present invention can be implemented into a deformed form by a person skilled in the art of the present invention without departing from the essential features of the present invention. Therefore, the disclosed embodiments and experimental examples should not be considered from a limiting perspective, but from an illustrative perspective. The scope of the present invention should not be defined by the above description, but should be defined by the appended claims, and all distinguishing technical features within the equivalent scope thereof should fall within the scope of the present invention.
