摘　　要：目的:旨在探讨金属无机盐离子对油包水(W/O)乳化体系稳定性和保湿效果的影响,为开发稳定性优良且保湿效果显著的W/O型护肤品提供理论支持。方法:首先将氯化钠(NaCl)、硫酸镁(MgSO_(4))、氯化钙(CaCl_(2))和氯化钾(KCl)分别添加到W/O乳液的基础配方中进行筛选,并评估其对乳液外观、黏度和稳定性的影响。再研究不同质量分数(0.1%至0.5%)对乳液稳定性、即时保湿效果、持久保湿效果和经表皮水分散失(TEWL)的影响。结果:NaCl的添加显著提升了W/O乳液的稳定性,尤其是在耐热性、耐寒性和离心实验中表现出卓越的性能。进一步研究表明,添加0.3%NaCl的W/O乳液在保湿效果上最为出色。结论:金属无机盐离子对W/O乳化体系的稳定性和保湿效果具有显著影响。添加0.3%NaCl可以制备出稳定性优良且保湿效果显著的W/O型护肤品。Objective:This study aims to explore the influence of metal inorganic salt ions on the stability and moisturizing effect of water-in-oil(W/O)emulsion systems,providing theoretical support for the development of W/O type skin care products with excellent stability and significant moisturizing effects.Methods:Firstly,sodium chloride(NaCl),magnesium sulfate(MgSO_(4)),calcium chloride(CaCl_(2)),and potassium chloride(KCl)were respectively added to the basic formula of W/O emulsion for screening,and their effects on the appearance,viscosity,and stability of the emulsion were evaluated.Then,the effects of different concentrations(0.1%to 0.5%)on the stability of the emulsion,immediate moisturizing effect,long lasting moisturizing effect,and transepidermal water loss(TEWL)were studied.Results:The study found that the addition of NaCl significantly improved the stability of the W/O emulsion,especially showing outstanding performance in heat resistance,cold resistance,and centrifugation experiments.Further research indicated that the W/O emulsion with 0.3%NaCl addition had the most excellent moisturizing effect.Conclusion:Metal inorganic salt ions have a significant impact on the stability and moisturizing effect of W/O emulsion systems.Adding 0.3%NaCl can prepare W/O type skin care products with excellent stability and significant moisturizing effects.
