摘要：保湿剂从平衡的角度来看既要让皮肤保持水分保持油脂，又有NMF来保持皮肤的吸水性和保湿性；芦荟具有保湿性早已有报道。芦荟所具有的保湿性与其成分密切相关；芦荟中含有的芦荟多糖具有保湿性；在防晒剂中，二氧化钛和氧化锌是良好的紫外线反射剂，但它们的亮白特性限制了其使用功能。纳米氧化锌能够有地效屏蔽UVA，所以近年来在防晒化妆品中其得到广泛的应用。纳米氧化锌、二氧化钛无机粒子的悬浮分散液；掌握护肤乳液的制备方法，研制出护肤霜并根据试剂用量不同找到最合适的配方以及成分的作用，并测定在不同温度下护肤霜的稳定性。以及制备空白护肤霜，之后与分别添加纳米氧化锌的护肤霜与绿色护肤霜进行对比实验。此配方膏体细腻，使用肤感较好，保湿效果显著，不油腻，易吸收，膏体呈乳白色，pH=6-7；经过多组实验，得出加入纳米氧化ZnO粉末0.4 g，反应温度85 ℃，反应时间1.5 h是样品最佳效果。 29870

Development of green moisturizing skin care products
Abstract: From the perspective of balance of moisturizing agent should keep the skin moisture and grease, NMF to keep the skin moisture absorption and moisture retention; Aloe Vera has already reported. Moisturizing aloe is closely related to its components; aloe polysaccharide in aloe contains moisturizing; in sunscreen, titanium dioxide and Zinc Oxide ultraviolet reflecting agent good, but their white properties limit its use function. Nano Zinc Oxide can effectively shield the UVA, so in recent years in sunscreen cosmetics have been used widely. Zinc Oxide suspended nano inorganic particles, titanium dioxide dispersion; grasp the preparation method of skin lotion, skin cream and developed according to different dosage of reagents to find the most suitable formulations and ingredients, and determine the stability of skin cream at different temperatures. And the preparation of blank cream, after comparison and respectively adding nano Zinc Oxide cream and green skin cream. The formula of fine paste, use the skin feeling good, moisturizing effect, not greasy, easy to absorb, paste the milky white, pH=6-7; after many experiments, the oxidation of ZnO nano powder 0.4g, reaction temperature is 85 DEG C, the reaction time is 1.5h the best effect of sample.
