Kao Develops Novel Deodorizing Technology
TOKYO (Nikkei)--Kao Corp. (4452) says it has developed a way to neutralize bad odors when they reach the nose, and that it plans to introduce the technology in nursing- and skin-care products in about five years.
Olfactory receptors located in the mucous surface of the nose are capable of detecting about 10,000 different odors. Kao says it has pinpointed a molecule that impairs the functions of the receptors that detect hexanoic acid, which gives body odor its characteristic aroma.
According to the company, test subjects exposed to a mixture of hexanoic acid and the molecule said the odor was more than 80% weaker than that produced by hexanoic acid alone.
Kao says the molecule is already being used as a fragrance ingredient in soaps and poses no health risks.
