Unicharm's Chinese website announced two Lifree care pads for odour management on July 9, 2026. One contains jasmine fragrance oil. The other adds activated carbon to the absorbent surface, which the company describes as physically adsorbing ammonia and indole, substances associated with unpleasant odours. The launch presents these as two approaches to addressing odour during care and pad changes.
A footnote states that both products have deodorising effects on ammonia and indole. It identifies 中轻纸品检验认证有限公司, a paper-products inspection and certification company, as the source of the testing data and specifies that the results apply only to the samples submitted for testing.
