摘要
通过分别对1,2-己二醇和对羟基苯乙酮的防腐功效评价,提出了1,2-己二醇和对羟基苯乙酮的新型复配防腐方案。研究了该复配方案在水剂、O/W乳液、凝胶、膏霜等剂型配方中,不同复配比例对细菌和真菌的抑制效果。实验结果表明:当复配物中1,2-己二醇和对羟基苯乙酮的质量分数均为0.5%,或当1,2-己二醇的质量分数为0.8%、对羟基苯乙酮的质量分数为0.4%时,对不同剂型中的细菌和真菌都具有非常出色的抑制效果。
Through the separate antimicrobial efficacy evaluation of 1,2 - hexanediol and p - hydroxyacetophenone, a new synergistic blend of 1,2 - hexanediol and p - hydroxyacetophenone was proposed. Inhibiting effect for bacteria and fungi of the blend system with separate blending ratios in various cosmetic formulations, including lotions, O/W emulsions, gels and creams et al. were examined. Results showed that when mass fraction of both 1,2 - hexanediol and p - hydroxyacetophenone are 0. 5% , or mass fraction of 1,2 - hexanediol and p - hydroxyacetophenone is 0. 8% and 0. 4% respectively, excellent inhibiting effect for bacteria and fungi in all above- mentioned cosmetic products can be obtained.
