Glycerin or glycerol, the pure chemical form of glycerin, is used in many soaps, skin creams and shampoos. However, some people can actually be allergic to glycerin and suffer a number of adverse reactions when exposed to it.
People with allergies to glycerin may have problems avoiding the chemical because of its pervasive use in consumer products. Though some control of the substance can be maintained in a home environment, people who suffer glycerin allergies on a job may need to seek other employment if they cannot handle their environment.
In addition to soaps, skin creams and shampoos, people with glycerin allergies may have sensitivities to other household items that contain the chemical, including toothpaste, shaving cream, perfume, cologne, metals, leather and some medications.
A person with glycerin allergies can suffer from skin conditions such as dermatitis, which can cause redness, itching and burning. More severe reactions include dizziness, nausea, swelling of the tongue or face, diarrhea and shortness of breath.
People with glycerin allergies may suffer from multiple chemical sensitivities. This condition often affects people with weakened immune systems or those who have been overexposed to glycerin and other chemicals.
People suffering from glycerin allergies should substitute certain hypoallergenic products for their commercial soaps and shampoos. It is best to be referred to an allergist to get tested and receive proper treatment.
