Description

Liquid Hair Moisturizing Nutritional Composition {Liquid Type Transparent Hair Care Composition}

The present invention relates to a hair moisturizing nutrient. More specifically, the present invention relates to a liquid transparent hair moisturizing nutrient composition comprising myristyl alcohol.

Hair needs some moisture for flexibility and elasticity. Maintaining a constant moisture content of hair is important for maintaining the health of hair and combing in low humidity conditions causes static electricity to accumulate due to friction, which causes hair to float and dust. In addition, combing worsens hair damage. Hair moisturizers are a type of cosmetic agent that exerts a clinic effect of penetrating damaged hair and instantly repairs the hair to make the hair instantly shiny and smooth. The formulation is usually cream, lotion or liquid. For the purpose of the use of hair moisturizers, liquids rather than creams or lotions are preferred in that they can provide immediate effects. Commercially available hair nutrients in liquid formulations are all based on silicone and protein. However, since they are polymers, they do not penetrate the hair well, and thus cannot be effectively used compared to the amount used.

Therefore, there is a need for continuous development of new liquid moisturizing nutrients in the form of improved liquids in terms of effects such as hair penetration of the ingredients, and an object of the present invention is to instantly absorb the components of the hair moisturizer and give vitality to the hair immediately upon use. It is to provide a liquid hair nutrient for maximizing moisturizing.

The present inventors use 1,3-butylene glycol, myristyle alcohol, and stearyltrimethylammonium chloride as main ingredients to provide fast, continuous and maximized moisturizing and oily feeling. And hair moisturizers that provide a wool effect. In addition, the present inventors have developed a hair moisturizing nutrient which exhibits excellent transparency and prevents coagulation of components providing moisture and oiliness at room temperature by using a small amount of purified water together with about 25% to 30% by weight of ethanol.

Thus, the present invention is based on the total weight of the composition 45 to 60% by weight of 1,3-butylene glycol, 3 to 5% by weight of myristyl alcohol, 6 to 8% by weight of stearyltrimethylammonium chloride (30 ), 6 to 8% by weight of purified water and the residual amount of ethanol to provide a liquid and transparent hair moisturizing nutrition composition at room temperature.

In another aspect, the present invention is based on the total weight of the composition to melt 3 to 5% by weight of myristyl alcohol to a temperature of 75 ℃ to melt and melt the 45 to 60% by weight of 1,3-butylene glycol And 6 to 8% by weight of stearyl trimethylammonium chloride (30) is added to the mixture, and 6 to 8% by weight of purified water is added thereto, and then the temperature of the solution is lowered to 50 ° C., and thus the solution of 50 ° C. thus formed It provides a method for preparing a liquid and transparent hair moisturizing nutrient composition at room temperature, including the step of adding a residual amount of ethanol.

The myristyl alcohol used in the liquid hair moisturizing nutrient composition of the present invention has a melting point of 45 ° C. and is solid at room temperature itself, so that it is usually mixed with a cosmetic ingredient in an amount of 3 to 5% by weight and used on a viscous cream or lotion. Known as an ingredient. In short, myristyl alcohol is a substance conventionally used in cosmetics for the purpose of increasing the viscosity. However, in the present invention, the myristyl alcohol is present in a state in which it is dissolved in a liquid rather than a normal cream or lotion phase as a use for giving a hair moisturizing effect and oily feeling. In the liquid hair moisturizing nutrient of the present invention, myristyl alcohol is used in an amount of 3% to 5% based on the total weight of the composition. If it is used more than 5%, it solidifies rapidly at high temperature and is difficult to dissolve once solidified. When used below 3%, the moisturizing effect and oily feeling are weak.

1,3-butylene glycol contained in the liquid hair nutrient composition of the present invention is well known as a humectant and is used in a large amount, which is characteristically 45 to 60% by weight in the present invention. Liquid hair moisturizers currently marketed or known in the literature contain less than about 10%. 1,3-butylene glycol contained in a large amount in the liquid hair moisturizing nutrient composition of the present invention inherently moisturizes with ethanol used in the liquid hair moisturizing nutrient composition as well as providing a moisturizing nutritional effect to the hair. It also acts to prevent the coagulation of myristyl alcohol, which provides an oily feel.

Stearyltrimethylammonium chloride contained in the liquid hair moisturizing nutrient composition of the present invention is a cationic surfactant which is cured when the temperature is lowered and is usually used on creams in connection with cosmetics. The liquid hair moisturizing nutrient composition of the present invention provides a wool effect to the hair. This substance is contained within 4% by weight of conventional hair-related products because it irritates the scalp. However, in the liquid hair moisturizing nutrient composition of the present invention, the stearyltrimethylammonium clyde 30 is used in an amount of 6 to 8 weight, which is more than the amount normally used, and it can be used in such a large amount as described above. This is because it is used in a very large amount, and thus the liquid hair moisturizing nutrient composition of the present invention has no irritation to the scalp and excellent wool effect.

The liquid hair moisturizing nutrient composition of the present invention maintains a liquid state at room temperature while containing a small amount of purified water. The amount of purified water used in the liquid hair moisturizing nutrient composition of the present invention is preferably about 6% by weight to 8% by weight as an amount to provide a transparent formulation while dissolving the pigment component. In other words, if the purified water is 6% by weight or less, it is not possible to dissolve components such as pigments, and if purified water is used at 8% by weight or more, the transparency is poor.

The liquid hair moisturizing nutrient composition of the present invention uses a larger amount of ethanol than purified water with a small amount of purified water as a solvent, and the preferred amount of use is 28% by weight to 32% by weight, most preferably 28% by weight.

The liquid hair moisturizing nutrient composition of the present invention may contain a small amount of materials commonly used in hair related products. For example, a pigment, a liposome incorporating hyaluronic acid which is a moisturizer, a pH adjuster such as lactic acid, an orchid oil, a suspending agent, a fragrance, a sunscreen, and the like are included. These additives may be used in an extremely small amount, as required by those skilled in the art, to reduce the amount of ethanol contained in the composition of the present invention by a small amount and to use an appropriate amount by such amount, and does not affect the desired effect of the present invention. In the case of the pH adjuster, since the isoelectric point of hair is about 5.5, it is preferable to use the amount of the liquid hair moisturizing nutrient of the present invention in an amount such that the pH is maintained at 4.5 to 5.5, and the content thereof is extremely small and about 0.0025% by weight.

The liquid hair moisturizing nutrient composition according to the present invention is prepared through the following steps:

(a) myristyl alcohol is melted at a temperature of 70 ° C to 80 ° C;

(b) the melt is added to a mixture of 1,3-butylene glycol and stearyltrimethylammonium chloride;

(c) mix the solution resulting from (b) with purified water and, if a sunscreen is used, dissolve it in purified water beforehand and mix with the solution produced from (b);

(d) lowering the mixed liquid of (c) to a temperature of 50 ° C;

(e) the 50 ° C. solution of (d) was added to ethanol;

(f) if necessary, the pigment is dissolved in purified water and the formed solution is added to the solution of (e);

(g) If necessary, other pH modifiers, liposomes, suspending agents, flavoring agents and the like are added to produce a liquid hair moisturizing composition having a pH of 4.5 to 5.5.

The liquid hair moisturizing nutrient composition according to the present invention is converted into a solid at a low temperature of 4 ° C. or lower, and converted directly to a liquid at room temperature. The moisturizing, oiliness, and wool effects are preserved regardless of the phase change. The hair moisturizing nutrient composition of the present invention has a low molecular weight of 1,3-butylene glycol, which is liquid at room temperature and contains a large amount as a moisturizing agent, and thus has an excellent moisturizing effect due to immediate penetration into hair. In addition, the hair moisturizing nutrient composition of the present invention contains myristyl alcohol, which is commonly used as a viscosity enhancer in creams or lotions, but exhibits excellent oiliness with additional moisturizing effect by myristyl alcohol while maintaining a transparent liquid phase. There is a characteristic. Additionally the hair moisturizing nutrient composition of the present invention is characterized by increasing the tensile strength of the hair.

The invention will be more specifically illustrated by the following examples. However, these examples are merely embodiments of the present invention and do not limit the scope of the present invention.

Experimental Example 1: Hair Shine and Gloss Test

In order to examine the moisturizing effect on the hair composition of the preparation example, nine male and female volunteers each with a slight hair damage were selected. Before the experiment, the hair was always washed using a normal shampoo without rinse function. After shampooing the hair, the composition prepared in the Preparation Example was massaged to the hair for 2 minutes and 30 seconds, rinsed with lukewarm water for 1 minute, and dried with a dryer to completely remove moisture.

Gloss and shine after shampooing (0 days), after massage and after 1 hour (1 hour), after 3 days (3 days), after 5 days (5 days) Was evaluated. In addition, after 7 days, the hair was massaged with the post-shampoo composition and dried in the same manner (7 days), and then after 7 days without the massage with the shampoo and the composition (14 days), hair gloss and gloss were evaluated. . The results are as described in Table 2 below.

◎ Best ○ Good △ Normal ▽ Slightly damaged ▼ Rough damage

From the above results, it can be seen that the composition of the present invention gives the hair moisture and oiliness immediately and continuously.

Experimental Example 2: Determination of Softening Effect of Dry Hair

In order to investigate the softening effect of the dry hair with respect to the hair composition of the preparation example, prepare a hairtress (weight 3g, length 25cm) and massage with the composition of the preparation example for 2 minutes 30 seconds, After rinsing for 1 minute, the resultant was dried with a dryer to remove moisture and the friction force was measured. The frictional force was measured using a KES-SE friction tester (KATO TECH CO., Ltd, JAPAN), and the average value was obtained by measuring three times for each hairtress to minimize the test error. The resulting dynamic friction coefficient (μk) was in the range of about 0.14 to 0.20. The coefficient of kinetic friction in this range is low, and as a result, the composition of the present invention can be seen that the moisturizing and wool effect is excellent by giving a softening effect to dry hair.

Experimental Example 3: Evaluation of Ease of Combing in Wet Hair

In order to evaluate the ease of combing in wet hair after being applied to the composition of the preparation example, 5 g of the hair bundle was triturated with a general shampoo without a rinse function, the composition of the preparation example was taken, massaged for 2 minutes and 30 seconds, and washed with lukewarm water. After combing the excess water from the hair and combing with a constant force, the number of combs until free and smooth combing was performed in the same manner 5 times for each of the above compositions to obtain an average to evaluate the ease of combing in wet hair. As a control, the number of combs was evaluated on wet hair after swallowing on the same hair before massaging with the composition of Preparation Example. As a result, after applying the composition prepared in the embodiment of the present invention, the number of combs was about 5 to 7 times, while the control group was 12 to 15 times. These results show that the combing ease in wet hair by the composition of the present invention is excellent.

Experimental Example 4: Hair Tensile Strength

The tensile strength of the hair was measured using INSTRONG (Switzerland) equipment during the test period for all nine female volunteers out of the 18 volunteers who participated in the test of Experimental Example 1. The results are shown in Table 3 below, where the figures are the average value of hair tensile strength (N (Newton) / cm ² ) for 5 ol per volunteer.
