Description

A cosmetic composition comprising tamarind seed gum {Cosmetic composition comprising Tamarindus Indica Seed Gum}

The present invention relates to a cosmetic composition comprising tamarind seed gum, and more particularly, to a cosmetic composition comprising tamarind seed gum on the external surface and having a uniform quality with no difference in temperature characteristics including a low melting point high-hardness butter or wax- And improving the spreadability and stability.

Looking at the basic cosmetics currently available, xanthan gum and acrylic polymers are used to help stabilize cosmetic formulations. Zanthan helps to surface cosmetics uniformly due to its black anionic properties, but it causes a difference in temperature properties in a high-hardness product, thereby deteriorating the uniform quality of the cosmetic. In addition, the cosmetic material mainly forms a high hardness cream by using fatty alcohol or wax.

When a commercially available lotion, essence, cream or the like is produced only with a high-hardness butter, there is a problem that the hardness tends to increase and the spreadability is poor. In particular, in the case of cream, most of wax-shaped raw materials are used in order to enhance the feeling of nourishment feeling and moisturizing ability, resulting in a rapid increase in viscosity and hardness and a drastic decrease in spreading ability. A problem arises. In the case of cosmetics containing a large amount of butter, due to the nature of the butter, hardness is not formed immediately after heating and cooling. Also, a high amount of butter can easily be separated at high temperature or give a feeling of feeling of burden.

Cosmetics applied directly to the skin have only a low-melting point, high-hardness butter, and there is not yet a cosmetic having the same properties as those used and circulated at room temperature and melting after application.

The present inventors have conducted studies to solve the above problems. As a result, they have found that using tamarind seed gum on the trauma and using a low-melting-point high-hardness butter or wax-like raw material on the inner surface have uniform quality without temperature difference, It is possible to provide an improved cosmetic composition and completed the present invention.

It is an object of the present invention to provide a cosmetic composition having uniform quality without temperature difference property and improved wettability and stability.

In order to solve the above-described problems, the present invention provides a cosmetic composition comprising tamarind seed gum on the trauma and a low-melting-point high-hardness butter or wax-like raw material on the inner surface at 40 ° C or lower.

The cosmetic composition of the present invention is an OW type in which the outer surface of the aqueous phase containing tamarind seed gums is filled with an oil phase containing an oil phase material having a low melting point,

It has a disadvantage in that the uniform quality of the cosmetic is deteriorated by causing a difference in temperature property between the black and hard black products. In addition, the raw materials on the wax having a high melting point rapidly increase viscosity and hardness under refrigerated distribution conditions of the room-temperature distribution cosmetic material, and degrade the spreadability remarkably or cause precipitation or the like, thereby lowering the stability. It is difficult to exclude the use of wax as a necessary raw material, such as forming a moistening film after the application to the skin to prevent dryness of the skin and giving a luster to the skin.

In the present invention, it was confirmed that a tamarind seed gum was used instead of xanthan gum to provide a uniform quality cosmetic composition with no difference in temperature characteristics.

In addition, as a result of investigating the effects of the wax-like raw materials on the cosmetic properties according to the temperature, the wax-like raw materials having a melting point of 40 캜 or higher and a melting point of 40 캜 or more lower the spreadability and stability, It has been found that low melting point waxy raw materials do not cause the above problems.

Accordingly, the present invention is characterized in that tamarind seed gum is contained in place of xanthan gum in a traumatic water phase, and a low melting point high-hardness butter or a wax-like raw material having a temperature of 40 ° C or lower is contained in an oil phase, To provide a cosmetic composition which is improved in spreading and stability.

Preferably, the present invention is characterized by containing tamarind seed gum on the external surface in an amount of 0.05% by weight to 5.0% by weight based on the total weight of the cosmetic composition.

If the content of tamarind seed gum is less than 0.05% by weight, there is a disadvantage in that the homogeneous property between the temperatures is not maintained, and if it is more than 5.0% by weight, the spreadability and feeling are deteriorated.

As used herein, the term " tamarind seed gum " is a seed meal of Tamarind Tree, an evergreen soybean, and is a polysaccharide composed of glucose as the main chain and xylose and galactose as the side chain. The viscosity is about 1.0% 200cps, 1.5% 600 ~ 700cps, and it has a liquidity close to Newtonian fluid and gives a rich feeling. In addition, the average molecular weight is about 115,000, stable in the pH range of 3 to 11, and is hardly affected by pH fluctuations, and is not affected by salts such as salt present in food. In addition, tamarind seed is resistant to 65% of its viscosity under sterilization conditions at 120 ℃, has excellent stability over time, and has a very elastic and intact gel.

In the experimental example of the present invention, when tamarind seed gum is used, formation of a rough butter form and formation of a body feel are better than that of a conventional xanthan gum, and 100% natural-derived polymer has superior formability and stability. Has excellent compatibility and has excellent properties in terms of high temperature and thermal stability. Thus, it has been confirmed that the natural polymer improves the formation of the hardness cream formulations and helps the formation of the system.

Further, preferably, the present invention is characterized in that the low-melting-point high-hardness wax-like raw material having an internal phase of 40 DEG C or lower contains 10.0 wt% to 50.0 wt% of the total weight of the cosmetic composition.

If less than 10.0% by weight of the low-melting-point wax-like raw material is less than 40 ° C, a feeling of good feeling of use, moisturizing effect, and hardness formation are not sufficiently exhibited. If it is more than 50.0% by weight, there is a problem.

As used herein, the term " low-melting-point high-hardness buttery or waxy raw material at 40 DEG C or lower " means raw material in butter or wax having a low melting point of 40 DEG C or lower but exhibiting high hardness at room temperature and existing in a solid state. In the present invention, a low melting point of 40 캜 or lower may mean a low melting point of 20 to 30 캜 on average. The low melting point buttery or waxy raw material of 40 ° C or less of the present invention exhibits a high degree of hardness at the time of refrigeration or circulation at room temperature but is melted before and after application of the skin due to a low melting point of 40 ° C or less.

As for the cosmetics currently in circulation at room temperature, raw materials of a high-melting-point wax at a temperature of 40 ° C or higher and low-melting waxes of a temperature of 40 ° C or lower are widely used for various purposes without selecting a melting point. However, raw materials having a high melting point of 40 ° C or higher have problems as mentioned above, and raw materials having a low melting point of 40 ° C or lower should be used.

Specific examples of the low-melting-point, high-hardness buttery or waxy raw materials usable in the present invention include vegetable oils such as shea butter, cucumber butter, barba soap butter and cacao butter, lanolin and bis-phage-18 methyl Hydrocarbons such as paraffin and vaseline, esters, and the like, and one or more of them may be selected from these. In the examples of the present invention, shea butter, cucumber butter and barberry soap butter were used.

In the experimental examples of the present invention, it was found that when using low melting point butter or waxy raw materials having a melting point of 40 DEG C or lower together with tamarind seed gum, compared to the case of using xanthan gum or a material having a high melting point wax at 40 DEG C or higher, It is confirmed that the viscosity difference is not so large, it is stable without precipitation, the moisturizing ability of the skin does not deteriorate, the efficacy is maintained, and the spreadability, absorption power, moisturizing power and overall feeling are excellent.

In addition, the cosmetic composition of the present invention can further prevent ethanol from being rapidly cured in cosmetics containing a large amount of butter.

Preferably, the present invention comprises ethanol in an amount of 3.0 wt% to 30 wt% based on the total weight of the cosmetic composition.

If the amount of ethanol is less than 3.0% by weight, hardness is not formed well and the spreadability is deteriorated. If the amount is more than 30% by weight, stability is lowered.

In addition, the cosmetic composition of the present invention may further comprise starch. In particular, the present invention relates to a method for preventing the separation of a high content of butter from a high temperature by utilizing amphipathic nature of starch, and a method for producing a stable active ingredient without deteriorating shape, spreadability and basic effect The effect can be further enhanced.

Preferably, the present invention comprises starch in an amount of 1% to 20% by weight relative to the total weight of the cosmetic composition.

If the amount of the starch is less than 1 wt%, the stability tends to deteriorate. If the amount of the starch is more than 20 wt%, the spreadability and feeling of use are deteriorated.

The starch usable in the present invention may be, but is not limited to, one or more starches selected from starches derived from tapioca, rice or corn.

The cosmetic composition of the present invention can be provided in formulations such as basic cosmetics, makeup cosmetics, body cosmetics, hair cosmetics, and scalp cosmetics. The formulations of the basic cosmetics include creams, packs, nutritional creams, massage creams, cleansing creams, cleansing foams, and the formulations of body cosmetics include sunscreen creams. The makeup cosmetics include foundation, makeup base, Hair cosmetics such as hair treatments, hair color preparations and hair blisters, and scalp treatments such as scalp cosmetics.

Hereinafter, the constitution and effects of the present invention will be described in more detail through examples. These embodiments are only for illustrating the present invention, and the scope of the present invention is not limited by these embodiments.

Example  1 and Comparative Example  1-2

The composition of the cosmetic composition was as shown in Table 1 below (unit: wt%).

In Example 1, in Table 1, raw materials 10 to 12 were sequentially dispersed in raw material 9, raw materials 13 to 14 were added, and the water was heated and dissolved at a temperature of 70 to 75 ° C. The raw material 1-8 was weighed in a beaker and heated to 70 to 75 ° C and dissolved. The mixture was slowly added to the water phase and uniformly emulsified with a homomixer for 10 minutes. Thereafter, the fragrance of the raw materials 15, 16 and the raw material 17 was added during defoaming and cooling and completely cooled to room temperature to prepare a shear thinning high-hardness cosmetic composition. Comparative Example 1-2 was prepared in the same manner as in Example 1.

Experimental Example  1: Comparison of physical properties and stability

Table 2 shows the comparison of physical properties through the change of hardness at room temperature (25 ° C) and the temperature change (5 ° C) of Example 1 and Comparative Example 1, and the precipitation phenomenon according to changes with time to observe stability.

<Evaluation Criteria for Precipitation>

No abnormality: X, small lump appearance: △, hard grain: O

Example 1 Comparative Example 1 Comparative Example 2 Room temperature (25 ° C) Hardness 300 310 250 Refrigerated (5 ℃) Hardness 400 420 490 Precipitation X △ △

As a result, as shown in Table 2, in Example 1 using tamarind seed gum as a trauma, the difference in viscosity at room temperature and in a cold state was not large and was stable without precipitation. On the other hand, in the case of Comparative Examples 1 and 2 using xanthan gum or a material having a high-melting-point wax phase at 40 占 폚 or higher, the viscosity increases sharply or gelation phenomenon (gelling) occurs. In addition, as a result of aging, small granules were aggregated and hard granules were observed, indicating that stability was greatly reduced. As a result, it was found that the use of tamarind seed gum and a low-melting-point waxy raw material having a melting point lower than 40 ° C can be used as a stable cosmetic material with little difference in physical properties.

Experimental Example  2: Skin Moisture power  compare

In order to measure the moisture resistance of the skin, the water retention capacity of Example 1 and Comparative Examples 1 and 2 was evaluated. The electrical conductivity of the skin surface was measured using a SKICON-200 (IBS Co., Japan). The measurement conditions were a temperature of 22 ° C and a relative humidity of 50%, and a sample of 0.03 g per 16 cm 2 of the skin After coating, measurements were made at each time point and repeated twice. The number of subjects was 20, and the unit was μ / Ω.

Experiment Item Example 1 Comparative Example 1 Comparative Example 2 Primary 30 minutes after application 186 164 182 120 minutes after application 164 142 161 Secondary 30 minutes after application 193 169 191 120 minutes after application 178 151 172

As a result, as shown in Table 3, it can be seen that Example 1 and Comparative Example 2 using tamarind seed gum had better skin moisturizing power than Comparative Example 1 in which no tamarind seed raw material was used. Thus, it can be seen that the use of tamarind seed gum and wax-like raw materials is necessary for moisturizing the skin. Further, it can be seen that the tamarind seed gum and the low melting point wax of Example 1 are superior to the high melting point wax of Comparative Example 2 in that the skin moisturizing power is not deteriorated and that the same effect can be obtained.

Experimental Example  3: Feeling  evaluation

Fifty women aged 25-45 were divided into four groups. Each of the groups was appropriately adjusted for each of the groups according to Example 1 and Comparative Examples 1 and 2, and then used on both sides of the face. Then, according to the following evaluation criteria, Moisturizing power and feeling of total feeling were evaluated, and the results are shown in Table 4 below.

<Evaluation Criteria>

Poor: 1, Poor Poor: 2, Moderate: 3, Slightly Good: 4, Very Good: 5

Item Example 1 Comparative Example 1 Comparative Example 2 Brittle 4.3 3.3 1.0 absorptivity 4.5 3.5 1.4 Moisture power 4.2 3.6 2.0 Overall feeling 4.4 3.4 1.1

As a result, as shown in Table 4, the cosmetic composition of Example 1 in which tamarind seed gum and a low melting point waxy raw material at 40 캜 or less were used in the evaluation of feelings for actual women was compared with Comparative Example 1-2 It was confirmed that it is a cosmetic composition remarkably superior in all parts, namely, spreadability, absorbency, moisturizing power and overall feel.
