Problems solved by technology

One is to use carbon dioxide gas as a raw material and store it in a viscous substance under pressure, for example: Japanese Patent Laid-Open No. 2002-255831, but this external skin preparation containing carbon dioxide is not only complicated in preparation method, Moreover, the prepared skin external preparations need to be stored in a strict airtight manner to avoid the volatilization of carbon dioxide.
The other is a composition containing carbonates and acids. Before use, carbonates and acids are mixed, and the carbonates and acids react to generate carbon dioxide to prepare skin external preparations. The most widely used ones are carbonates. The composition of water-soluble mixture and acid particles, but the carbonate-soluble mixture in this composition has strong alkalinity, and the acid particles have strong acidity, which will cause the instability of other ingredients in the composition, so that there are complex ingredients restricted question

Embodiment 1

[0024] Mix 0.25 grams of sodium alginate and 1.00 grams of 1,3-butanediol evenly, add 3.70 grams of carbonic acid aqueous solution, mix, bubbles are formed, the viscosity of the mixture gradually increases, and a transparent sticky substance is formed. Apply this sticky substance to the left hand On the inner side of the forearm, there was a strong cold / irritating sensation, and the skin became visibly red within 5 minutes. After 30 minutes, scrape the gunk off with a small pad and wash the skin with water.

Embodiment 2

[0026] Mix 0.15 grams of sodium carboxymethyl cellulose and 1.00 grams of 1,3-butanediol evenly, add 3.95 grams of carbonic acid aqueous solution, mix, bubbles are formed, the viscosity of the mixture gradually increases, and a transparent sticky substance is formed. Applied on the inner side of the left forearm, there was a strong cooling / irritating sensation, and the skin became visibly red within 5 minutes. After 30 minutes, scrape the gunk off with a small pad and wash the skin with water.

Embodiment 3

[0028] Mix 0.12 grams of cotinus cotinus seeds, 1.20 grams of 1,3 butanediol, add 3.30 grams of carbonic acid aqueous solution, mix, bubbles are formed, the viscosity of the mixture gradually increases, and a transparent sticky substance is formed. Apply this sticky substance to the left hand On the inner side of the forearm, there was a strong cold / irritating sensation, and the skin became visibly red within 5 minutes. After 30 minutes, scrape the gunk off with a small pad and wash the skin with water.

Abstract

The invention discloses a carbon dioxide-containing external composition for skin and a preparation method of the carbon dioxide-containing external composition for skin. The composition contains a component A and a component B, wherein the component A is carbon dioxide aqueous solution obtained by dissolving carbon dioxide in water to reach a saturated state, and the component B is a mixture composed of a thickener and a dispersant. When the component A and the component B are mixed, the viscosity of the mixture is rapidly increased to generate a sticky object, and thus carbon dioxide is stored in the sticky object. The obtained sticky object can be used for external application for the skin, and has the beautifying and treatment effects of carbon dioxide. The use method of the composition can be the direct mixed use of the component A and the component B, or the component B can be uniformly coated on a water-absorbent supporter and used by contacting with the component A.

Description

technical field [0001] The invention relates to an external skin composition containing carbon dioxide and a preparation method thereof, which have cosmetic, skin care and therapeutic effects. Background technique [0002] Water containing carbon dioxide has been known for a long time to improve blood circulation, and carbonated hot springs were developed from this. Later, we developed technologies related to carbon dioxide-containing skin / hair cleansers, sprays, and film-based skin external preparations by utilizing this function of carbon dioxide. Among them, external preparations containing carbon dioxide are the most widely used carbon dioxide external preparations because they have a strong percutaneous absorption of carbon dioxide and have a significant skin improvement function. [0003] There are known two types of membrane-type skin external preparations containing carbon dioxide. One is to use carbon dioxide gas as a raw material and store it in a viscous substan...
