The culprit is excessive organic solvents. Aromatics are neither drinks nor contact with the skin. How can they be harmful to health? The main components of perfume include perfume and organic solvent, and perfume can be divided into three types: natural extraction, semi-synthesis and chemical synthesis. Organic solvent is an indispensable substance to help perfume volatilize into the air. The harm of fragrance to health comes from toxic or excessive organic solvents. A research report from Bristol University in Edinburgh, UK further pointed out that if pregnant women often come into contact with deodorizing products or aromatic products containing excessive organic solvents, the chances of babies born to these pregnant women suffering from diarrhea will be higher than that of ordinary babies. Pregnant women should be especially careful not to touch toxic organic solvents.
