Yunsha is a brand of human body lubrication.

Human body lubricant is a lubricant specially designed for human body, which is different from mechanical use and has wide applicability and high safety. A good human lubricant not only increases the lubrication effect, enhances sexual pleasure, makes sexual life more harmonious, and enhances the feelings between husband and wife; At the same time, it can reduce skin damage and reduce the erosion opportunities of harmful microorganisms such as bacteria and viruses on human body; Effectively reduce the damage of condoms and reduce the chance of accidental pregnancy.

glycerin and hydrophilic substances were the main components of the early human lubricant, and then sodium hyaluronate, ethyl cellulose, carbomer and other components were added after improvement. After improvement, the viscosity was reduced, the pH value was balanced, so that it was as similar as possible to human body fluids, and the incidence of allergic symptoms was reduced.

With the development of science and the enhancement of people's awareness of natural environmental protection, the water-soluble human body lubricant popular in the 2th century has gradually faded out of the industry abroad, for example, it has become more popular in Europe and Oceania, and has been replaced by a more environmentally-friendly pure natural human body lubricant extracted from corn, beets, roses and other plants (without any chemical components except preservatives) or a water-fat human body lubricant with a longer lubrication time.

Extended information

Types of human body lubricants:

Water-based lubricants

are made of water and fibers, which are most acceptable on the body surface. It is easy to lose its effect after drying, but it will recover after supplementing water. Therefore, it is often used as a sexual lubricant.

Oils

are made of mineral oil, which, unlike water-based, will not react with body fluids, so the effect is lasting. The lubrication effect is poor. This kind of lubricant has a long-lasting effect and is difficult to clean. Often used for medical purposes. Oil-based lubricants will weaken the effectiveness of condoms, and lubricants attached to the body surface will easily increase bacterial infection.

siliceous

mixture of silicon and oil. Easy to react with substances containing silicon, such as silica gel.
