The mechanism of action of silicone oil to kill lice eggs
Recently, in the field of lice prevention and control, the method of silicone oil to kill lice eggs has become more and more popular. Silicone oil, as well as chemical substances, has a special mechanism for killing lice eggs.

First, silicone oil has strong wettability. Lice eggs are attached to the hair and are fixed according to the sticky force. Silicone oil touches it and quickly covers the surface of the egg. With its wettability, it enters the small gap between lice eggs and hair, reducing the stickiness between eggs and hair. Egg stickiness is weak, and it is easy to fall off from the hair. When it is in natural activities or grooming, it loses its survival base. This is one way.

Second, silicone oil forms a closed membrane. Silicone oil covers lice eggs and forms a continuous closed membrane on the surface of the egg. The hatching of lice eggs requires gas exchange and a moderate wet environment. This closed membrane blocks gas from entering the egg, causing the egg to be hypoxic, and improper moisture control, disrupting the physiological process in the egg, and the embryo development is difficult, making it difficult to hatch young lice. This is the second way.

Furthermore, silicone oil disturbs the surface tension of lice eggs. The surface of lice eggs has a specific surface tension to maintain their morphological and structural stability. Silicone oil is added to it to change the surface tension and break the physical balance of the egg surface. The structure of the egg surface is broken, the contents are infiltrated or dehydrated, the environment in the egg is damaged, and the embryo of young lice is inhibited, and it cannot be incubated. This is the third way.

In summary, silicone oil has obvious efficacy in killing lice eggs by wetting and reducing viscosity, sealing air and moisture, and disturbing surface tension. Its method is different from traditional chemical agents, and there is no risk of chemical residues and drug resistance. It is a good method for the prevention and control of lice infestation. It has promising application prospects in the field of health care.
