Problems solved by technology

However, the above-mentioned conventional lubricants have a problem of poor feeling during use and after use.
That is, when in use, due to the adhesion of the film formed by the evaporation of the solvent, the irritation to the mucous membrane or the skin brings discomfort to the user, and there is a problem that it is difficult to wash with water after use.

Embodiment 1

[0024] A 3% (mass ratio) aqueous solution of sodium polyacrylate with Pv=38,000 has a viscosity of 10,100 cps / 36° C. and a pH of 9. If the pH of the aqueous solution is adjusted to 5.5 by polyacrylic acid, the viscosity will reach 10,050cps / 36°C. In this way, a low solid content lubricant exhibiting lubricity suitable for human body can be produced. The lubricant of this embodiment is diluted with doubled water when used. Viscosity reaches 10,100cps / 25°C.

[0025] This solution is a mucous membrane protective agent with good viscosity and lubricity.

Embodiment 2

[0027] Sodium polyacrylate of Pv=38,000 was dissolved in a mixed solvent of water:ethylene glycol=95:5 mass ratio at a concentration (mass ratio) of 5%. The resulting solution had a viscosity of 7,450 cps / 36°C. As a polymeric acid, if the pH of the above solution is adjusted to 5.5 by using a copolymer powder of triallylether (triallylether) of 99.7 parts by mass of acrylic acid and 0.3 parts by mass of glucose, the viscosity will reach 7,600 cps / 36°C. And be modulated into the same excellent lubricant as embodiment 1.

Abstract

The invention relates to a lubricant, aiming at providing the lubricant which is used for protecting mucosa such as rectum, oral cavity and the like, in particular to cavitary internal mucosa, and simultaneously causes the lubrication to become good. The lubricant is a solution comprising polyacrylate sodium and is prepared by the step that the polyacrylate sodium with more than 10000 average degree of polymerization of viscosity is dissolved by water or water solubility. The water or water-solubility solvent and the polyacrylate sodium have the following mass ratio relationship: the water or water-solubility solvent is 91-99 mass percent, the polyacrylate sodium is 9-1 mass percent, the viscosity of the solution is 3000-30000cps in 36 DEG C, and the pH value of the solution is adjusted to range from 3.5-10.5 by adding polymer acid. When in use, the product does not bring displeasure caused by membrane feel and incitation, and can be easily cleaned with water after being used, thereby the lubricant has good use feeling.

Description

technical field [0001] The present invention relates to a lubricant, more specifically, a lubricant for protecting mucous membranes such as rectum and oral cavity, especially mucous membranes in cavities, and at the same time making lubrication better. Background technique [0002] In the past, during massage or sexual intercourse between men and women, it was used to protect the mucous membranes of various parts and at the same time make the lubrication better. of lubricants. However, the aforementioned conventional lubricants have a problem of poor feeling during use and after use. That is, during use, the adherence of the film formed by the evaporation of the solvent, the irritation to the mucous membrane or the skin gives the user discomfort, and there is a problem that it is difficult to wash with water after use. [0003] The present invention aims at solving the problems in the prior art. Its purpose is to provide a lubricant that feels good during use and after us...
