Silicone-free cosmetic composition for hair improvement {SILICONE-FREE COSMETIC COMPOSITION FOR HAIR IMPROVEMENT}

The present invention relates to a cosmetic composition for improving hair without using silicone oil.

As modern lifestyles become more common, surface damage to hair is getting worse due to external stimuli such as excessive combing, drying, and frequent washing, or penetration of chemicals. Accordingly, there is an increasing demand for hair care products (eg, shampoo, rinse, hair conditioner, hair treatment, etc.) that can prevent damage to hair, protect hair, and have excellent glossiness and comb texture.

Silicone oil has been used as a raw material for hair cleaners and cosmetics because it has a high molecular weight, a small change in viscosity according to temperature change, a light and silky feeling of use, and continuous gloss and luster when used on hair.

However, as silicone oil is an environmental pollutant, research results that can harm biodiversity are announced one after another, and in Europe, silicone oil is banned from being used in washing products, and the use of silicone oil is being restricted worldwide. . In addition, when silicone ingredients are used in hair products, there is a problem that the silicone ingredients clog pores, and when silicone oil is used for a long time, pores with active sebum secretion are clogged and sebum cannot escape properly, resulting in scalp inflammation such as folliculitis. there is.

Due to the above problems, an object of the present invention is to provide an environmentally friendly cosmetic composition for improving hair while maintaining the excellent hair conditioning effect of conventional silicone oil.

[Experimental Example 1: Evaluation of hair conditioning effect]

In order to evaluate the hair conditioning effect according to the use of Comparative Examples 1 to 6 and Examples 1 to 12, experimental hair weighing 1.5 g and length 100 mm was tested for friction using a friction coefficient tester (Neo-Tribo (FCMS 170)). After measuring and evenly applying Comparative Examples 1 to 6 and Examples 1 to 12 on the same hair, it was dried and the frictional force was measured using a friction coefficient tester (Neo-Tribo (FCMS 170)). It is shown in Table 3 below.

The friction coefficient was measured repeatedly 10 times, and the average was obtained. The smaller the friction coefficient, the better the hair conditioning effect.

friction coefficient average 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 Example 11 0.076 0.004 Example 12 0.083 0.018

Silicone oil (Comparative Example 1), mineral oil (Comparative Example 2), or ethanol mainly used in cosmetics (Comparative Example 3), which are generally used to make hair soft (silky), are used in oil composed of hydrocarbons. It was confirmed that Comparative Examples 4 to 6 and Examples 1 to 12 used were effective in hair conditioning. In addition, in the case of ethanol or hydrocarbons, there was a high volatility problem due to a low boiling point (BP) problem, so emollients were used to compensate, and when hydrocarbons and emollients were mixed in an appropriate ratio, it was confirmed that remarkable excellence in hair conditioning appeared. .

Through Comparative Example 4 and Example 2, it was confirmed that it was effective when the emollient was maintained at a certain amount or more, and when alkylbenzoate was included through Examples 2 to 4, the friction coefficient was smaller and the conditioning effect was more effective. As can be seen, through Examples 5 to 7, it was confirmed that the hair conditioning effect was more excellent when the carboxylic acid group derivative emollient was further included than the polyhydric alcohol derivative emollient.

[Experimental Example 2: Evaluation of wool effect]

In order to evaluate the wool effect, Comparative Examples 1 to 6 and Examples 1 to 12 were evenly applied to the experimental hair samples, respectively, and dried.

The gloss band, which appears as light scattered from the hair surface, is photographed by illuminating a hair sample with constant light, and then the photographed image is analyzed and evaluated.

From the captured image, the gloss band was extracted using an analysis program, and the pixel values of the area occupied by the gloss band were obtained in comparison to the total area, and are shown in Table 4 below.

As the area of the gloss band increases, the glossiness increases.

Gloss band area value (number of fixels) untreated 1840 Comparative Example 1 2992 Comparative Example 3 2519 Comparative Example 4 2680 Comparative Example 6 2621 Example 2 3090 Example 3 3409 Example 4 3473 Example 5 3492 Example 7 3184 Example 8 3772 Example 9 3955 Example 10 4301 Example 11 4322 Example 12 4987

It was confirmed that Comparative Example 1 using silicone oil exhibited better effects than other Comparative Example compositions, and exhibited effects close to those of Example 2. However, the compositions of the Examples showed superior gloss than the Comparative Examples, and through this, it can be seen that the Examples of the present invention exhibit a better wool effect than silicone oil without using silicone oil.

[Experimental Example 3: Comparative evaluation of oily hair]

In order to evaluate the oiliness, Comparative Examples 1 to 6 and Examples 1 to 12 were evenly applied to the test hair samples, respectively, and dried.

After being left for 24 hours, 10 panelists were visually observed and evaluated according to the following evaluation criteria, and the results are shown in Table 5 below.

Evaluation standard

Referring to Table 5, Comparative Example 2 using only mineral oil had the most severe hair breakage, and conventionally commonly used silicone oil showed good results. Although the composition of the examples of the present invention did not use silicone oil, it exhibited a feeling of use that was similar to or felt appropriate to silicone oil.

[Experimental Example 4: Evaluation of dye retention]

In order to evaluate the dye retention of Comparative Examples 1 to 6 and Examples 1 to 12, the hair dye is evenly applied to each experimental hair sample, left for 40 minutes, washed with running water using shampoo, and dried using a hair dryer. .

Comparative Examples 1 to 6 and Examples 1 to 12 were evenly applied to the dried hair, and then ultraviolet rays were irradiated for 24 hours, and then the color was measured using a Chromameter CM700.

The brightness values measured by a color difference meter (Chromameter CM700) are shown in Table 6 below, and were compared using the L* value as a brightness index. At this time, L+ represents brightness and L- represents darkness. Also, the higher the L value, the brighter it means. In addition, the larger the value of Δ L (unprocessed value-processed value) means that the color is missing a lot, and the smaller the value, the lower the value means that the existing color is well maintained without a difference in color before and after the experiment.

brightness value △ L untreated 44.54 - Comparative Example 1 40.93 3.61 Comparative Example 4 42.31 2.23 Comparative Example 5 41.37 3.17 Comparative Example 6 41.27 3.27 Example 1 42.16 2.38 Example 2 42.81 1.73 Example 5 43.42 1.12 Example 7 42.47 2.07 Example 10 43.02 1.52 Example 11 42.54 2.00 Example 12 43.26 1.28

(Unit: L*)

Compared to commonly used silicone oil (Comparative Example 1), Comparative Examples 4 to 6 and Examples 1 to 12 composed of hydrocarbons and emollients showed superior results in color retention even after dyeing. In addition, the compositions of Examples showed better results in color retention than those of Comparative Examples.

[Experimental Example 5: Evaluation of tangled hair loosening efficacy (Combining test)]

In order to evaluate the detangling effect of tangled hair, Comparative Examples 1 to 6 and Examples 1 to 12 were evenly applied to each experimental hair sample (back combing was performed 5 times), and then dried.

The number of times of combing until completely loosened by combing the hair sample was measured and shown in Table 7 below.

The fewer times of combing, the less entanglement of the hair.

The hair entanglement phenomenon was more effective when the composition of Comparative Example or Example was applied than when it was not treated, and the effect of the commonly used silicone oil (Comparative Example 1) was superior to that of other comparative example compositions. In addition, the compositions of the examples of the present invention showed effects similar to those of silicone oil even though silicone oil was not used.

[Experimental Example 6: Anti-Fizz Evaluation]

In order to evaluate the Anti-Frizz of Comparative Examples 1 to 7 and Examples 1 to 11, the experimental hair was heat-permed, the hair was naturally dried, and the hair was completely spread using a straightener to make the experimental hair.

The compositions of Examples and Comparative Examples were evenly applied to the experimental hair samples and dried.
