Unicharm has a long history of production in China, and came to China in 1995, starting with "Sophie", and has established a very high reputation. In 1987, Unicharm launched adult diapers, and the Le Huyi brand was born. In the field of personal care, Le Huyi has created a precedent for a number of innovative products such as "underwear diapers", with a market share of up to 60% in Japan.

Lehuyi set up an excretory care research institute in Japan to popularize the correct use of excretory care products, and its nursing pad series also came to China in 2011. Unicharm has several factories in Shanghai, Tianjin, and Yangzhou, and adopts the strategy of local production and local sales. The product line is relatively simple, there are not many single products, and there is only one nursing pad, which is mainly light and breathable, and the absorption is slightly lower than that of European and American brands such as TEN.

Adult incontinence products are gradually being recognized and accepted by society, and nursing pads are generally used in conjunction with diapers to prevent leakage and prolong the use time. The uniform specification of 60cmx90cm nursing pad is 60cmx90cm, regardless of size, and the bed needs of mothers, menstruating women, and incontinence patients can be met, and the reference price of a single piece is 2.3 yuan.

Unlike baby diapers, price-oriented consumption dominates the adult incontinence market, and buyers generally pursue more cost-effectiveness. In terms of caring for incontinence people, Le Huyi has really done a good job, it is the star product with the largest market share in Japan, but its sales in China have not been among the top three, and it is not as good as the brand marketing of Zhongqi, Reliable, Bao Daren and other low-end products with a higher proportion of marketing.
