Embodiment 1

[0032] Example 1: 20% urea cream

[0033] 20% urea, 10% liquid paraffin, 5% stearic acid, 2% cetearyl alcohol, 3.5% vaseline, 15% glycerin, 0.4% triethanolamine, 0.18% sodium lauryl sulfate, paraben Add 0.08% ester, appropriate amount of essence, and pure water to 100% ratio, put oil phase materials: liquid paraffin, stearic acid, cetearyl alcohol, vaseline, ethyl paraben in a container, and heat to 75-80°C, stir until completely melted, add vitamin E, stir well and keep at 80°C; add water phase materials: sodium lauryl sulfate, urea, triethanolamine into purified water, stir well until the materials are completely dissolved, then add Glycerin, stir well and heat to 80°C. Under continuous stirring, the oil phase was slowly added to the water phase, and then homogenized at 2000 rpm for 5 minutes. Stop heating, add essence when the paste is cooled to 50°C, stir well, and discharge at 40°C. Filling and packaging after aging for 24 hours is a composition provided by the present...

Abstract

The invention discloses application of urea in prevention and/or treatment of a skin injury caused by electro-welding radiation. In conjunction with experimental data and human body using effect data, the invention finds out that an external preparation prepared from an active ingredient namely the urea and common accessories or auxiliary ingredients has a function of preventing and treating the skin injury caused by the electro-welding radiation, particularly has a remarkable effect of alleviating skin burning tingling and erythema desquamation caused by the electro-welding radiation, does not have toxic and side effects after a long time, and has a great application prospect.

Description

technical field [0001] The present invention relates to a new application of urea, especially the application in preventing and / or treating skin damage caused by electric welding radiation. Background technique [0002] Electric welding, also known as arc welding, is a process in which the arc heat effect generated by welding equipment promotes the partial heating and melting of the cross-section of the metal to be welded to a liquid state, and combines the originally separated metals into a firm non-detachable joint. In this process, the temperature of the object can reach 2000-20000°C, which will produce high-intensity ultraviolet, infrared and visible light (infrared and ultraviolet radiation can be generated when the surface temperature of the object reaches above 1200°C). [0003] The investigation found that the radiation produced by electric welding can cause serious damage to the skin of the face and hands of the workers. Among them, the main ones that are harmful t...
