The required purity of trehalose for food grade is greater than 98%

The requirement for cosmetic grade is greater than 99%

If the purity is slightly higher, the cost will naturally be higher If you pay a lot, the price will naturally be much higher.

Cosmetic grade can replace food grade, but food grade cannot replace cosmetic grade.

I don’t know what your company’s requirements are. If it is used for cosmetics, it can only use cosmetic grade, because cosmetics are mostly used on the head and face. It does not cause skin irritation. If it is used in cosmetics, it will not have any impact on consumers. Caused too many adverse reaction complaints. If cosmetics are replaced by food-grade ones, it is likely that more adverse reactions or side effects will occur among consumers. The impact on people's faces is much more severe than stomachaches, so don't penny wise and pound foolish.
