Description

Low-viscosity easy-absorption human body lubricant and preparation method thereof Technical Field The application relates to the field of human body lubricants, in particular to a low-viscosity easy-absorption human body lubricant and a preparation method thereof. Background Human lubricants are lubricants used in human sexual activity to reduce friction between body parts or between body parts and other objects. It reduces skin damage by increasing the lubrication effect and can effectively reduce the risk of condom breakage. The main products currently on the market are mostly aqueous lubricants, the main components of which generally comprise water, humectants (such as glycerol, propylene glycol) and thickeners added to ensure the rheological properties (such as carbomers, hydroxyethyl cellulose). Although such formulations solve the basic water solubility and cleaning problems, there are still significant technical limitations in practical applications in that conventional formulations often rely on high proportions of thickening agents or macromolecular film-forming materials to increase the viscosity of the system in order to achieve the desired lubrication durability. Although the lubrication time is prolonged, the product is too sticky and difficult to wipe evenly when in use, the skin absorptivity is poor, a layer of sticky film is easy to remain on the surface after the product is dried, discomfort is caused, and the user experience is seriously affected. Disclosure of Invention In order to improve the viscosity of the human body lubricant, the application provides a low-viscosity and easy-absorption human body lubricant and a preparation method thereof.
