毒理性
硫酸盐月桂醇钠(SMS)的安全性由化妆品成分审查(CIR)专家小组进行了评估。SMS被用作32种化妆品中的表面活性剂和清洁剂,浓度高达50.0%。讨论了SMS的毒理学特性。含有7% SMS的未稀释洗发水在白兔身上引起了轻到中度的眼睛刺激。当洗发水稀释到含有1.4% SMS时,只观察到最小的眼睛刺激。由于没有可用的SMS毒理学数据,因此审查了与SMS化学结构相似的物质——硫酸盐月桂醇钠(SLS)的安全评估数据。SLS在口服给药实验动物时,仅表现出轻微的急性、亚慢性和慢性毒性。SLS在1.3%至15.0%的浓度下引起轻度眼睛刺激,在17.5%至30.0%的浓度下引起中到重度眼睛刺激。30%和60%的SLS会引起严重皮肤刺激。在兔子上测试时,SLS在5.0%至5.6%的浓度下没有引起皮肤刺激,在6.0%至10.0%的浓度下引起最小刺激,在25.0%的浓度下引起严重刺激。SLS在豚鼠中是一种致敏剂。SLS在实验动物中没有诱导生殖毒性和致癌性。专家小组根据SMS和SLS的数据得出结论,SMS作为目前使用的化妆品成分是安全的。
The safety of sodium myreth sulfate (SMS) was assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. ... SMS has been used as a surfactant and cleansing agent in 32 cosmetic products at concentrations up to 50.0%. The toxicological properties of SMS were discussed. An undiluted shampoo containing 7% SMS was a mild to moderate eye irritant in albino rabbits. When the shampoo was diluted so that it contained 1.4% SMS, only minimal eye irritation was observed. Because there were no toxicological data on SMS available, data from a safety assessment of sodium laureth sulfate (SLS), a chemically similar compound, were reviewed. SLS has shown only slight, acute, subchronic, and chronic toxicity when administered orally to experimental animals. SLS caused mild eye irritation at concentrations of 1.3 to 15.0%, and moderate to severe eye irritation at 17.5 to 30.0%. SLS at 30 and 60% caused severe skin irritation. In rabbits, SLS caused no skin irritation when tested at concentrations of 5.0 to 5.6%, minimal irritation at 6.0 to 10.0%, and severe irritation when tested at 25.0%. SLS was a sensitizing agent in guinea pigs. SLS did not induce reproductive toxicity or carcinogenicity in experimental animals. The Expert Panel concluded that on the basis of the data for SMS and SLS, SMS is safe as a cosmetic ingredient as presently used.
