摘要:考察了油脂种类、溶解方式、储存条件及乳化剂对当前使用最广泛的防晒剂二乙氨基羟苯甲酰基苯甲酸
己酯(DHHB)的溶解度及结晶情况的影响。在肉豆蔻酸异丙酯(IPM)、辛酸/癸酸三甘油酯(318)、碳酸二乙
基己酯(DEC)、C12-15 醇苯甲酸酯(TN)、碳酸二辛酯(CC)、异壬酸异壬酯(ININ)、苯甲酸苯乙酯(226)
7 种油脂中,分子结构中含有苯环数目较多的 226 对 DHHB 的相容性最佳,超声溶解后 25 ℃下放置 28 d 时的
溶解度为 241.08 g/L;加热溶解 25 ℃放置 1~28 d 时 DHHB 在各油脂中的溶解度下降率比超声溶解溶解度下降
率降低 10%以上,其中,在 226 中的溶解度下降率降低了 35.72%;乳化剂的加入可明显减缓 DHHB 在 CC 中的
溶解度下降率,其中,加入 Span20 后溶解度下降率降低了 20.07%,加入 Span80 后溶解度下降率降低了 21.27%。

Abstract: The effects of oil type, dissolution method, storage condition and emulsifier on the solubility and
crystallization of hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (DHHB), the most widely used
sunscreen agent, were investigated. Among the 7 types of fat: isopropyl myristate (IPM), caprylic/capric
triglyceride (318), bis(2-ethylhexyl) carbonate (DEC), C12-15 alkyl benzoate (TN), carbonicacid, dioctylester
(CC), isononyl isononanoate (ININ) and phenethyl benzoate (226), 226 containing a large number of
benzene rings in its molecular structure displayed the best compatibility for DHHB, showing a solubility of
241.08 g/L when stored at 25 ℃ for 28 d after ultrasonic dissolution. When DHHB was stored at 25 ℃
for 1 d to 28 d after heated dissolution, the solubility decline rate in each oil decreased by more than 10% in
comparison to that of ultrasonic dissolution, of which the solubility decline rate in 226 was reduced by
35.72%. Moreover, the addition of emulsifier could significantly slow down the solubility decline rate of
DHHB in dioctyl carbonate (CC), and the solubility decline rate reduced by 20.07% after Span20 addition
while decreased by 21.27% with Span80 addition.
