Condoms are now a method of contraception for many men and women. Compared with intrauterine contraceptive devices, condoms are less harmful and can prevent more unwanted pregnancies. Condoms are also very effective in preventing pregnancy. When you use a condom for the first time, you will find that there is always a lot of oil on it. This is lubricant. Lubricant is not harmful to the body and is an oil that can be accepted by the human body. Today, let's popularize the knowledge of lubricants on condoms: There are many types of lubricants. Usually we classify them according to their sources into mineral lubricants, vegetable lubricants, animal lubricants and synthetic lubricants. In addition, according to their uses, they can be divided into industrial lubricants and personal lubricants. The lubricant on condoms is a synthetic human lubricant. Its main ingredient is dimethyl silicone oil, a non-petroleum-based lubricant. Generally, regular manufacturers use edible grade lubricants, which mainly serve as lubrication and are harmless to the human body. Of course, we do not recommend users to try the taste of this silicone oil, because this synthetic mineral oil itself is not easy to decompose and difficult to be absorbed by the human body, so it takes a long time to excrete after entering the human body. Lubricants have been used in human sexual life for a long time. In the early days, people used vegetable oils such as peanut oil and olive oil. However, due to the limitations of its ingredients, the effect is not ideal. It can easily stain clothes and is not easily absorbed by the body. Later, people also tried to use petroleum-based mineral oil substances such as Vaseline, baby oil, bath gel, and massage oil as lubricants. These substances are often too sticky and difficult to clean. They are likely to leave residue after use and may even block the urethra of both men and women, causing painful urination. They can also destroy the stability of condoms and cause unwanted pregnancies, all of which can cause harm to the human body. Dimethyl silicone oil is a more balanced choice for large-scale applications of lubricants. So, out of concern for these silicone oils, you may ask if there are any alternatives? The answer is of course yes. As material technology becomes increasingly advanced, a variety of lubricants are being used in the condom or sex toy industry. |
