Cosmetic composition comprising ethanol and amphiphilic surfactant for shortening the drying time of damaged hair containing ethanol and amphiphilic surfactant

The present invention relates to a cosmetic composition for reducing dry time for damaged hair containing ethanol and an amphiphilic surfactant.

Hair is composed of hydrophobic fur on the outer surface and hydrophilic cortex on the inside. In the case of damaged hair, as shown in FIG. 1, when the hydrophilic cortex is exposed and the hair is washed, moisture is captured and drying takes longer than healthy hair. Many people suffer from discomfort because of this. Furthermore, drying for a long time causes damage to the hair and adversely affects the health of the scalp. Therefore, there is a need for a hair care composition for shortening the drying time.

Accordingly, the present inventors coated the cortex as shown in FIG. 1 using a surfactant that will play a role in separating ethanol and water, which are volatile components that can shorten the drying time, from the hair, thereby shortening the drying time and adding various moisturizing ingredients. Thus, the present invention was completed by providing an optimal composition for hair drying capable of supplying nutrients to hair.

Hereinafter, preferred embodiments of the present invention will be described in detail. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, it is provided to sufficiently convey the spirit of the invention to those skilled in the art, so that the disclosure herein will be thorough and complete.

<Example 1. Confirmation of the possibility of using ethanol as a raw material for a cosmetic composition for reducing drying time - hair damage check>

As the main raw material of the cosmetic composition for reducing drying time, ethanol having the effect of enhancing the moisture evaporation effect was selected first. Ethanol used in the experiment was edible ethanol having a purity of 99%.

On the other hand, since there is a concern that ethanol may damage hair when used as a raw material for a composition for hair, the degree of hair damage that can occur when ethanol is applied to hair several times was confirmed. To this end, spraying ethanol directly on the hair and drying was repeated 30 times, and then the thickness and surface of the hair were observed using a scanning electron microscope (SEM). The SEM picture is shown in FIG. 2 . During the evaporation experiment, the room temperature was 30°C, the room humidity was 65%, and about 3.5 g of ethanol was sprayed 15 times per time.

As a result of the analysis, as shown in FIG. 2, it was found that ethanol did not damage the hair because the condition of the hair did not change and there was almost no change in the thickness of the hair itself even after drying after treating the hair 30 times or more.

<Example 2. Setting the content of ethanol as a raw material for a cosmetic composition for reducing drying time>

When ethanol is used as a raw material of a composition for hair, an experiment was conducted to set an appropriate mixing ratio in the composition. The results of measuring the evaporation time and the amount of evaporation by preparing an aqueous solution with an ethanol content of 10 to 90% (v / v) are shown in FIGS. 3 and 4. During the evaporation experiment, the room temperature was 30°C, the room humidity was 65%, and about 3.5 g of ethanol aqueous solution was sprayed 15 times per time.

As a result, as shown in FIG. 3, it was confirmed that the time required for all of the sprayed liquid phases to dry was not significantly different from when a 30% by weight aqueous ethanol solution was used. In addition, as shown in FIG. 4, as a result of measuring the weight of the hair at a certain time as a starting point and confirming the evaporation amount of the ethanol aqueous solution, the evaporation amount also increased significantly from the use of a 30% (v / v) ethanol aqueous solution.

Accordingly, adjusting the ethanol content to 30% (v/v) or more in the entire composition, but adjusting the maximum ethanol content to 50% (v/v) or less reduces the use of ethanol without significantly affecting the drying time. It was expected that the cost reduction effect in manufacturing the composition could also be brought about.

<Example 3. Setting the type and mixing ratio of surfactant as a raw material for a cosmetic composition for reducing drying time>

Next, a suitable surfactant composition as a raw material for a cosmetic composition for reducing drying time and a mixing content thereof were selected. The surfactants used in the experiment were cocobetaine and decyl glucoside, and were mixed at 0.2% by weight and 0.4% by weight, respectively, in a 30% by weight ethanol solution. The results for this are shown in Figure 4.

As a result of the analysis, as shown in FIG. 4, it was confirmed that the aqueous ethanol solution to which 0.2% by weight of decyl glucoside (Decyl) was added had the highest amount of evaporation. Coco betaine (CoCo) showed no significant change in evaporation amount at any concentration of 0.2% by weight or 0.4% by weight. As a result of repeated experiments, it was found that the use of a 30% (v/v) ethanol aqueous solution containing 0.2 to 0.3% by weight of decyl glucoside (Decyl) was most preferable for drying hair.

In addition, as a result of evaluating coco betaine and decyl glucoside for hair feel and moisture after drying when sprayed on hair, the experimenters selected a solution containing decyl glucoside as a composition with a better feel.

<Example 4. Preparation of final composition for drying damaged hair>

In addition to ethanol and a surfactant, additive components having a moisturizing function suitable for addition to a composition for hair were selected. All additives with moisturizing function were determined to be silicone oil, avocado oil, and bergamot oil, which are all natural substances or harmless to the human body. At this time, silicone oil plays the role of gloss, elasticity and anti-foaming of hair, avocado oil nourishes hair, and bergamot oil plays the role of fragrance to cover the ethanol scent. However, since the amount of evaporation should not be reduced by adding additives, the dryness of the hair was checked by adjusting the appropriate mixing amount of additives.

As a result, the mixing amount that does not suppress the amount of evaporation the most is 0.3 g of silicone oil and 0.1 g of avocado oil based on 10 g of ethanol aqueous solution (30% (v/v) ethanol aqueous solution containing 0.2 wt% of decyl glucoside) containing surfactant. g, when 0.3 g of bergamot oil was mixed (total weight 10.7 g). The evaporation amount at this time is shown in Table 1 below. As described above, the addition of silicone oil, avocado oil, and bergamot oil to the aqueous ethanol solution containing the surfactant is referred to as 'additive o', and only the surfactant containing When the ethanol aqueous solution was designated as 'additive x', the evaporation amount of these two solutions was the same.

<Example 5. Confirmation of total dry time>

It was confirmed whether the drying time was substantially shortened using the composition ^* prepared in Example 4. *(30% (v/v) ethanol aqueous solution with 0.2% by weight of decyl glucoside) A solution containing 0.3 g of silicone oil, 0.1 g of avocado oil, and 0.3 g of bergamot oil based on 10 g. The solution was put into a spray container as shown in FIG. 6 and used.

The experiment was conducted at a room temperature of 12 ° C and a room humidity of 70% to have a minimal effect on the hot air temperature of the hair dryer, and 25 g of the solution was sprayed on the artificial wig and tested.

As a result, as shown in FIG. 7, when water was used as a control, it took 13.27 minutes to completely dry, and the composition prepared in Example 4 took 10.15 minutes.

In addition, an experiment in which the temperature of 25 g of the composition was raised to 40 ° C. in consideration of the temperature of the hot air coming out of the hair dryer and evaporated in a beaker was also performed.

As a result, as shown in FIG. 8, it is confirmed that the evaporation rate differs by about 23% in the same time compared to water.
