抗氧化剂抑制人体皮脂油污自氧化反应研究

Study on Antioxidant's Inhibition of Human Sebum Soil from Autoxidation

服用纺织品的黄变现象与纺织品上人体皮脂组分残留物的自氧化反应密切相关。借鉴食品工程中减缓富脂食品氧化褐变的思路,选取几种在食品工程领域具有代表性的抗氧化剂(VE、VC、BHT、PG、TBHQ、BHA),研究其对于四种最易黄变的人体皮脂组分的抗氧化作用的差异性。结果表明:抗氧化剂能够抑制皮脂油污的自氧化反应,不同的抗氧化剂在不同皮脂油污组分中的抗氧化作用及自身的色变现象差别较大。抗氧化剂BHT具有显著的抗氧化能力,且自身的色变很小,适用于开发延缓服用纺织品老化黄变的新型纺织品洗护用品。

Yellowing of clothing and household textiles is closely related to the autoxidation of residual oily soil from human sebum. Several representative antioxidants （VE, VC, BHT, PG, TBHQ and BHA） used in food engineering field were selected through referring to the thought of slowing down rich-fat food oxidation and browning, and their differences in antioxidation behavior in sebum components were studied. The results show that antioxidants are able to slow down the autoxidation of sebum oil; different antioxidants have large differences in antioxygenation and color change phenomena in different sebum oil components. BHT has significant antioxidant ability and shows small color change. So, it is suitable for developing textile care products to delay aging and yellowing of household textiles.
