Regarding white petrolatum used for wound care
Vaseline (vaseline) is also called petrolatum. There are yellow petrolatum and white petrolatum depending on the color, and white petrolatum is said to have higher purity. White petrolatum is defined in the Japanese Pharmacopoeia as "purified by decolorizing a mixture of hydrocarbons obtained from petroleum." Used as a base for pharmaceuticals such as ointments and cosmetics such as cosmetic creams. It is also used as a lubricant and skin moisturizing protective agent.
Vaseline used for wound care should be white petrolatum with fewer impurities.
