Description

Ice-cold compound liquid and preparation method thereof

Technical Field

The invention relates to the field of cleaning products, in particular to a cold compound liquid and a preparation method thereof.

Background

The cool wet tissues on the market can be roughly divided into two types: one is a method for promoting heat dissipation by adopting volatile absorber heat of alcohol for the wet tissue, the wet tissue contains alcohol and water components, only can be used for temporarily cooling and cleaning the skin, but the cold feeling is poor in durability and large in irritation to the skin; the other type is that the single cold menthol is added into the wet tissue, the cold effect and the cold persistence are enhanced by increasing the using amount of the single cold menthol, but the prepared wet tissue has a lot of menthol and corresponding solubilizer remained in the skin, so the wet tissue has poor use feeling, such as greasy product and much foam, and the excessive use of the menthol causes more damage to the skin.
