Characteristics:
1) Sterilization, antibacterial, high efficiency, broad spectrum and long-lasting.
2) Methylisothiazolinone has good miscibility with water and is easy to use.
3) Methylisothiazolinone is completely harmless to be used in recommended concentrations.
4) Methylisothiazolinone does not accumulate in the environment and is easily degraded.
5) IMethylisothiazolinone can be used with pH value range of 2-11.
6) Good compatibility with surfactants and emulsifiers in personal care products.
Application
Methylisothiazolinone Applicable in aqueous system for personal care, cosmetics, paint and emulsion, etc.
Dosage
1)In aqueous system like paint, emulsion, etc, the recommended concentration is 0.30~0.1%(w/w); In personal care products, the usage is 0.1~0.5%(w/w),depends on whether the products is easy to be contaminated by microorganism and the storage environment.
2)This product can be added in any process, but shall avoid to be added with temperature above 50ºC, it is recommended to be added with temperature below 50ºC in last procedure.
Packing and Storage
1)Sealed plastic bottle with 25kg, 200kg and 1000kg.
2)The warranty period is one year.
Special note
1) Methylisothiazolinone should avoid direct contact with the eye. Once contact, rinse immediately with plenty of water. No delay. Do not contact with the skin for a long time.
2) Methylisothiazolinone should not be contacted with reducing metals during storage, such as metal iron and aluminum, so as to avoid decomposition of products
3) Methylisothiazolinone has poor stability in the alkaline medium of pH > 9 and is not suitable for use. Compatibility of highly nucleated chemicals with this product, such as S2- and R-NH2, will result in the deterioration or even failure of this product.
