JPH0656625A - Cosmetic containing low-strength agar-agar - Google Patents

Abstract

PURPOSE:To provide a cosmetic exhibiting an excellent effect unlike another cosmetic in which the conventional thickener is used. CONSTITUTION:This cosmetic contains a low-strength agar-agar whose jelly strength is controlled within a range of <=250g/cm<2> at 1.5wt.% agar-agar content by cutting and shortening the molecule of the agar-agar component.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention has a jelly strength of 1.5%.
The present invention relates to a cosmetic product using low-strength agar adjusted to have an agar concentration of 250 g / cm ² or less.

[0002]

2. Description of the Related Art Emulsions, creams, shampoos, packs,
In cosmetics such as dentifrice, tragacanth gum, karaya gum, pectin, sodium alginate, carrageenan, CMC, MC, PVP and the like have been conventionally used as thickeners.

However, recent cosmetics are "colorless".
Since the aspect of "unscented" tends to be preferred, the natural product orientation also becomes stronger in the material, and studies have been made on the use of agar extracted from seaweed as a thickener. This is because agar has active ingredients such as minerals and is considered to be a more natural cosmetic raw material.

[0004]

However, conventional agar has a strong gelling power. For example, the jelly strength (Nichikan-sui type, agar concentration 1.5%) is 4 for powder agar and flake agar.
It is more than 00 g / cm ² , and it is about 250 to 400 g / cm ² for Kaku agar and thread agar called natural agar. Therefore, when it is used at a high concentration, it lacks fluidity, and when it is actually contained in cosmetics, it is difficult to maintain a liquid or creamy aspect. In order to avoid this point, when conventional agar is used at a low concentration, its content is reduced, so that the original functions of the agar (thickening, permeability, etc.) cannot be expressed.

An object of the present invention is to provide a cosmetic product having excellent effects not found in the conventional cosmetic products using a thickener, by using low-strength agar which has fluidity even when used at a high concentration. There is.

[0006]

To achieve the above object, the cosmetic of the present invention has a molecule of agar component cleaved shortly, and the jelly strength is adjusted to a range of 250 g / cm ² or less at 1.5% agar concentration. It is characterized by containing low-strength agar.

[0007]

The low-strength agar used in the present invention has a jelly strength adjusted to a range of 250 g / cm ² or less at a 1.5% agar concentration, and therefore has excellent fluidity even when used at a high concentration. . Therefore, since the cosmetic of the present invention containing a large amount of this low-strength agar contains many natural minerals and the like, it has the effect of moisturizing the skin, smoothing it, and further cleaning it. This is because low-strength agar not only thickens,
This is because it has excellent permeability. In addition, in the case of an emulsified product such as an emulsion, it has an effect of helping the emulsion stability. This low-strength agar is one in which the molecules of the agar component have been cut short by acid and heat treatment to reduce the jelly strength, and the details are shown in Japanese Patent Application No. 4-148855.

[0008]

EXAMPLES Examples of the present invention will be described below. Example 1 of the present invention is an example in which 0.5 parts of low-strength agar was contained in 100 parts of the lotion.

[0009]

[Table 1] Example 1: Lotion Lotion Low strength agar 0.5 part Ethanol 5 parts Glycerin 5 parts Lemon liquid 2 parts Water 87.5 parts (total) (100 parts)

The lotion obtained with the above composition was superior in moisturizing, smoothing and cleansing effects to the skin lotion using a conventional thickener. .

Example 2 of the present invention is an example in which 3 parts of low-strength agar was added to a total of 100 parts of the pack agent.

[0012]

[Table 2] Example 2: Packing agent Low-strength agar 3 parts Glycerin 5 parts Ethanol 10 parts Perfume proper amount Preservative proper amount water 82 parts (total) (100 parts)

The packs obtained with the above composition are superior in moisturizing, smoothing and cleaning the skin to the packs using a conventional thickener. .

Example 3 of the present invention is an example in which 100 parts of shampoo liquid contains 1 part of low-strength agar.

[0015]

[Table 3] Example 3: shampoo liquid low-strength agar 1 part lauryl sulfate triethanolamine 15 parts lauric acid diethanolamide 2 parts Perfume proper amount pigment proper amount water 82 parts (total) (100 parts)

The shampoo liquid obtained by the above composition has the effect of moisturizing, smoothing and cleaning the skin, as compared with the conventional shampoo liquid using a thickener.
It was excellent.

The cosmetics of the present invention are not limited to the above examples, but can be applied to creams, dentifrices and the like. Further, the concentration of the low-strength agar used is not limited to the value in the example.

[0018]

As described above, according to the present invention, since the low-strength agar having the jelly strength adjusted to the range of 250 g / cm ² or less at the 1.5% agar concentration is contained, the conventional thickener is used. It is possible to provide a cosmetic product having excellent effects not found in the used cosmetic products.
