Does toothpaste relieve itching

Toothpaste is a common and frequently used daily necessity in people's daily lives. In fact, in addition to cleaning teeth, toothpaste has many other wonderful uses. For example, when your skin is itchy after being bitten by a mosquito, applying appropriate toothpaste will have a good anti-itching effect. This anti-itching effect of toothpaste is mainly related to its ingredients, such as mint, which is an ingredient that can make the skin feel cool.

1Why can toothpaste relieve itching?

Toothpaste can relieve itching. This is because after being bitten by a mosquito, the mosquito leaves formic acid in the human body, causing itching and redness. Toothpaste contains calcium carbonate or calcium bicarbonate powder, which is alkaline and can neutralize formic acid, so toothpaste can effectively relieve itching. Secondly, the mint ingredient in toothpaste can cool the itchy area and inhibit the sensation of nerve endings, thereby achieving the purpose of relieving itching.

2 Analysis of the ingredients of toothpaste

The production of toothpaste mainly includes four categories: abrasives, detergent foaming agents, moisturizers and thickeners. The calcium carbonate and light calcium carbonate mentioned above are abrasives and have a cleaning effect; the most commonly used foaming agent is 120,000-grade sodium sulfate or sodium dodecylbenzene iodate; commonly used moisturizers include glycerin, sorbitol, etc., which can prevent toothpaste from hardening; and the commonly used thickener is carboxymethyl cellulose, which can increase the overall viscosity of the toothpaste and prevent breakage or separation.
