本文揭示了具有可生物降解织物柔软活性剂和添加螯合剂的透明或半透明织物柔软组合物。可生物降解织物柔软活性剂优选具有以下公式:
其中,每个R取代基是氢或短链C1-C6,优选是C1-C3烷基或羟基烷基,例如,甲基(最优选),乙基,丙基,羟乙基等,苯甲基或其混合物;每个m为2或3;每个n为1至约4,优选为2;每个Y为—O—(O)C—,—(R)N—(O)C—,—C(O)—N(R)—或—C(O)—O—,优选为—O—(O)C—;当Y为—O—(O)C—或—(R)N—(O)—时,每个R1中碳的总数加一为C6-C22,优选为C12-22,更优选为C14-C20,但不超过一个R1或YR1总和小于约12,然后另一个R1或YR1总和至少约为16,每个R1为长链C5-C21(或C6-C22),优选为C9-C19(或C9-C20),最优选为C11-C17(或C12-C18),直链、支链、不饱和或多不饱和烷基,R1的父脂肪酸的平均碘值约为20至约140。螯合剂优选为二氨基三乙酸五钠盐。该组合物在Hunter Color分析的透射模式下具有出色的清晰度,其百分之雾度小于90%,优选小于50%。
