JAPAN: The Japanese Ministry of Health, Labour and Welfare (MHLW), Pharmaceutical Affairs Bureau approved methylisothiazolinone, the key ingredient in Rohm and Haas Company’s Neolone preservative. The MHLW has added methylisothiazolinone to the positive list of preservatives approved for use in leave-on and rinse-off cosmetic products at a maximum dosage of 100ppm. According to company executives, this decision recognizes the complete data package submitted by Rohm and Haas in support of Neolone and enables Neolone and its family of products to be used in cosmetic products produced in Japan or destined for the Japanese market.
The company also announced that the European Union voted to adopt the opinion of the European Commission’s Scientific Committee on Cosmetic Products that the proposed use of methylisothiazolinone as a preservative at a maximum concentration of .01% (100ppm) in the finished cosmetic product does not pose a risk to the health of the consumer. Neolone has now been independently approved for leave-on and rinse-off applications in the U.S., Japan and Europe.
