Abstract

PURPOSE:A cosmetic that uniformly contains Gell gum as a glue, thus being able to sufficiently exhibiting features a cosmetic sould possess, such as no taste, no injury to humans, no strange odor, good viscosity, extendability, resistances to acid and alkali. CONSTITUTION:A cosmetic, toilet soap, tooth paste and other flangrant products are combined with Gel gum, a polysaccharide produced by fermentation, uniformly to give a cosmetic which has comprehensively and sufficiently good features which a cosmetic and other products should possess such as high retention of perfume or flavors, good fitness to skin, no injury to human bodies such as skin, hairs or mucous membrane, high extendability, high resistances to acid and alkali. The amount of the Gell gum depends on the cosmetics, bus its satisfactory effect is excepted wilth about 0.05wt% in tooth paste.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to cosmetics, and an object of the present invention is to industrially advantageously obtain cosmetics with excellent quality.

[Problem that the invention seeks to solve]

Cosmetic products here refer to cosmetics, toilet soaps, toothpastes, and other aromatic products.

Regardless of the type, cosmetics must have the following properties: ■ High ability to retain fragrance; ■ Excellent texture; ■ Harmless to the skin, hair, mucous membranes, and other parts of the human body. (2) It has a high degree of aromatic properties, (2) It is stable without separating its contents, (2) It has no off-taste or odor, (2) It spreads easily, and (2) It has excellent acid and alkali resistance.

A common method for imparting such properties is to homogeneously blend a sizing agent into product materials.

[Conventional technology]

Conventionally, CMC is used as a glue.

Examples include carrageenan, gelatin, xanthan gum, pregelatinized starch, and others, but none of these can be said to sufficiently exhibit the above-mentioned properties comprehensively. acid resistance,
This is due to poor alkali resistance, low fragrance retention, not necessarily good texture, and insufficient spreadability.

[Means for solving problems]

This invention utilizes fermented polysaccharide gellan gum (Gel fa
ngum).

This substance is easily (warm) soluble in water, and is a tasteless and odorless substance that is harmless to the human body. It has excellent viscosity, extensibility, acid and alkali resistance, and does not produce any unpleasant taste or odor when mixed with other cosmetic materials.

The amount of gellan gum to be added to cosmetics or its raw materials is as follows:
Since the power differs depending on the type of cosmetics, it cannot be displayed in a -i manner. So, as a specific example, if we take toothpaste, we can expect sufficient effects with about 0.05% (by weight, same hereinafter).

〔Effect of the invention〕

As one means of detecting the characteristics of cosmetics containing gellan gum, the characteristics of gellan gum and conventional thickening agents will be compared below.

Experimental Example The viscosity (unit: cp) of a 0.5% aqueous solution at 20°C was measured using a rotational viscometer (however, this system contained calcium lactate α
(including 1%).

Experimental example ff #5% hot sodium chloride, 0.5% locust bean gum,
Aqueous solutions of 0.5% guar gum and 0.5% gellan gum were heated and dissolved at 90°C, and further heated to 90°C and 160°C.
The mixture was heated at 120°C for 30 minutes, then cooled to 20°C, and the viscosity (cp) at the same temperature was measured using a rotational viscometer.

Experimental example■ Add 0.01% menthol to a 0.5% solution of each gum substance, store this in a thermostat at 40'C for one week, and perform a sensory test to compare the odor immediately after adding menthol. The remaining rate of the men l--/l/ was examined.

However, sample α was added to three types of water systems: tap water, pH 3 and pH 10.
After adding 5% and stirring at 90°C for 30 minutes, the mixture was cooled to 20°C and the viscosity was measured. 4% common salt was added after stirring at 90°C for 30 minutes.

Example 1 Lotion Ethylua/Recor Ni After dissolving polyoxyethylene cetyl ether, fragrance, and sorbic acid, 90% of a homogeneous mixture of gellan gum, water, and glycerin was added and mixed to obtain a lotion.

This product was allowed to stand at a temperature of 20''C for 6 months, but there was no deterioration in quality, the viscosity was extremely stable, and no off-taste or odor was produced.

Example 2 Gellan gum was dissolved in a liquid blusher, and a mixture of other raw materials dissolved and dispersed therein was added to make it homogeneous and emulsified to obtain a liquid blusher.

When this product was used on the human body, it had excellent adhesion and spreadability to the skin, and there was no discoloration.

Example 3 Add and disperse gellan gum to vinyl pack water, then add polyvinyl alcohol, and after cooling, add polyoxyethylene cetyl ether.
A solution of 1 fragrance and ethyl alcohol-μ was added and mixed uniformly to obtain a bag.

This material did not change in quality even after being left at 60°C for six months.

Example 4 Gellan gum, glycerin, sodium saccharin, sodium lauroy-sarcosine sodium laurisulfate were dispersed and mixed in toothpaste water, and the above solution was added to calcium carbonate to defoam to obtain toothpaste.

This product spread well in the oral cavity, had excellent flavor retention ability, and did not adversely affect the effects of other flavor components.

Example 5 Conditioning Dissolve gellan gum containing Shantu A in water and add fragrance and methylparaben. Heat this to 90°C. Next B
Mix each formulation and heat and stir at 80°C until dissolved. The product obtained by mixing the A and B formulations, cooling them to 35°C, and filling them was able to give smooth and soft hair.

Example 6 Dissolve dandruff and shampoo gellan gum in water and homogenize (150#/-)
Then, while degassing, the remaining formulation was added to obtain an anti-dandruff shampoo.

This shampoo was affected by the suspended dispersibility of the surfactant and zinc pyridione.

Example 7 Sunscreen cosmetics Liquid paraffin, olive oil, and coconut oil were mixed, gellan gum was added thereto, and the mixture was heated and dissolved (approximately s O'C). Other ingredients were added and cooled while stirring well. This product was an oil-based gel-type sunscreen cosmetic.

Example s Vanishing cream fat I (stearic acid, stearyl alcohol, and (stearyl butyl alcohol ester lv)) were all mixed together, heated and dissolved, and kept at 70°C.Separately, water, gellan gum, propylene glycol, and alkali were mixed. , 70°
The mixture was heated to C and added to the previously prepared fats and oils and mixed.

Next, the mixture was uniformly emulsified using a homomixer and cooled to 30°C-1''. This product had good emulsifying properties and moisturizing properties.
