Glycerol and hydrophilic substances were the main components of early human lubricating oil, 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.
At present, human lubricating oil can be divided into four types, including water-soluble, silicone, petroleum and oily. When purchasing, we should adhere to the principle of "simple ingredients, colorless and tasteless, giving priority to water-soluble and silicone".
Extended data:
The body lubricant shows its greatest effect during masturbation. A small drop of lubricant can turn an ordinary "manual work" into a lubricating and arousing experience. At the same time, it can also be used to eliminate the discomfort of first-time sex or long-time sex. Couples can also use it when having sex in the bath, because lubricant can eliminate the dryness caused by water.
Sex products are still secretive in China, which makes many people don't understand this kind of products, and often they just want to take one in the shop and leave, while more people are embarrassed to go and find their own solutions. For example, some people use vaseline and baby oil as lubricants in sex, which is actually very unsafe and scientific. Only using special human body lubricant can get the best effect, and there are no side effects such as residue.
