毒理性
识别和使用:2-萘磺酸钠(SNS)是一种化妆品成分。人体研究:SNS对人类皮肤的刺激性较弱。1%的SNS在人体受试者中不是致敏剂。动物研究:在眼刺激试验中,三只接触SNS的兔子中有一只显示出不可逆的眼部损伤。在兔皮肤上进行测试时,未稀释的SNS是轻微刺激物,但2%和20%的稀释液不刺激。SNS未能在豚鼠中诱导迟发型接触超敏反应。使用Salmonella typhimurium菌株TA 98、TA 100、TA 1535、TA 1537和TA 1538进行的Ames试验中,SNS结果为阴性。
IDENTIFICATION AND USE: Sodium 2-naphthalenesulfonate (SNS) is a cosmetic ingredient. HUMAN STUDIES: The skin irritation potential of SNS on human skin was weak. 1% SNS was not a dermal sensitizing agent in human subjects. ANIMAL STUDIES: In the eye irritation test, one out of three rabbits exposed to SNS showed irreversible ocular damage. When tested on rabbit skin, SNS was mild irritant when applied undiluted, but the 2% and 20% dilutions were not irritating. SNS did not induce delayed contact hypersensitivity in guinea pigs. SNS was negative in an Ames assay using Salmonella typhimurium strains TA 98, TA 100, TA 1535, TA 1537, and TA 1538.
