Under a contract from industry, researchers at the Fraunhofer Institute for Toxicology and Experimental Medicine ITEM investigated the effects of aerosols produced when using heated chemical hair products. In some cases, inhalation of the aerosols released when using heated hair products may lead to respiratory discomfort. Optimizing products before placement on the marketWorking under the industrial contract, the experts used the in vitro inhalation method to clarify the respiratory effects of heated hair treatment products. “Characterization of the aerosols released when the four hair products were applied to strands of real hair under realistic conditions revealed significant differences in aerosol formation rates and dose response.
