Specification
Sodium methylparaben , its cas register number is 5026-62-0. It also can be called p-Hydroxybenzoic acid methyl ester sodium salt ; Sodium (p-carboxyphenoxy)-methyl ester ; 4-Hydroxybenzoic acid methyl ester sodium salt ; Methyl 4-hydroxybenzoate sodium salt ; Methyl p-hydroxybenzoate sodium salt ; Methylparaben sodium ; Sodium 4-(methoxycarbonyl)phenoxide ; Sodium 4-carbomethoxyphenolate ; Sodium p-methoxycarbonylphenoxide ; and Sodium methyl p-hydroxybenzoate . It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon. While, it's inhaled: Remove from exposure and move to fresh air immediately. Give artificial respiration while not breathing. When breathing is difficult, give oxygen. And as soon as to get medical aid. Then you have the ingesting of the product: Wash mouth out with water, and get medical aid immediately. Notes to physician: Treat supportively and symptomatically.
In addition, Sodium methylparaben (CAS NO.5026-62-0) absorbs moisture or water from the air. It is not compatible with strong oxidizing agents, and you must not take it with incompatible materials, dust generation. It should be exposured to moist air or water. And also prevent it to broken down into hazardous decomposition products: carbon monoxide, carbon dioxide.
