漂流在化妆品界的技术要塞
Drifting in the technical fortress of cosmetic industry

　　在我们所知范围内凹凸棒的应用广泛用于农业、医学、食品、环保等部门领域。当然，也没想到在化妆品里它也存在于此，那么大家就疑问了，在化妆品里它是起着怎样的技术要点呢？

　　首先，大家要知道的一点则是我国是世界凹凸棒石主要资源国和生产国之一，主要产于苏、皖及甘肃三省，在工业和其它多种行业上具有特种用途。那么，化妆品在利用凹凸石黏土时是具有一些改性的，步骤为以下几大特性：

　　将凹凸棒石原矿破碎成2～5厘米小颗粒，自然晾干或者人工加热脱水至恒重，再将得到的干燥颗粒配置成质量分数为5～20%的泥浆搅拌，超声分散，过1200目筛分离，取滤液浓缩，得到含水量为50~75%的浆料。其中，搅拌时间为20~60min；超声分散时间为15～45min。

　　鸡蛋清添加其浆料中，于2～10℃下搅拌15～40min，通入氨气使含有凹凸棒石的泡沫上浮，鸡蛋清添加量为浆料质量的5～20%．收集所得的上浮泡沫，加入柠檬酸消泡，离心，洗涤，得到纯化的凹凸棒石；柠檬酸的添加量为浆料质量的1~10%；将纯化的凹凸棒石和d-葡萄糖醛酸（dga）于水中混合均匀，于60~100℃下回流15～30h。离心，洗涤，干燥，即得改性凹凸棒石，纯化的凹凸棒石与其质量比为1:0.1～1:1。

　　在化妆品界里凹凸棒起的研究效应就是这么多啦，当然，在我们日常中所知的药膏、药丸的悬浮剂粘结剂、化妆品的底料、缓释放香剂、蚊香粘结填充剂、附着剂都是有凹凸棒材质的存在，希望大家在应用时可对其做更多的知识面的了解认知，有助于更好的实践。

　　As far as we know, attapulgite is widely used in agriculture, medicine, food, environmental protection and other sectors. Of course, I didn't expect that it also existed in cosmetics, so we asked, what technical points does it play in cosmetics?
　　It is well known that attapulgite is one of the three major industries in China and the world. Then, the cosmetics have some modification when using attapulgite clay, and the steps are as follows:
　　The raw attapulgite ore is crushed into 2-5cm small particles, which are dried in the air or dehydrated manually to constant weight. Then the dried particles are prepared into slurry with mass fraction of 5-20%, stirred, ultrasonic dispersed, separated through 1200 mesh sieve, and concentrated with filtrate to obtain slurry with water content of 50-75%. The stirring time was 20 ~ 60 min and ultrasonic dispersion time was 15 ~ 45 min.
　　Egg white was added to the slurry, stirring at 15 40min for 2~10 to 15, and then adding ammonia to float the foam containing attapulgite. The egg white was added to the 5 20%. floating size of the slurry, and then the citric acid was defoaming, centrifugated and washed to obtain the purified attapulgite. The amount of citric acid was 1~10% of the pulp quality, and the purified attapulgite and glucose were purified. The mixture of DGA in water was uniform and refluxed at 60 ~ 100 ℃ for 15 ~ 30 h. The modified attapulgite was obtained by centrifugation, washing and drying. The ratio of purified attapulgite to its mass was 1:0.1 ~ 1:1.
　　There are so many research effects of attapulgite in the field of cosmetics. Of course, the paste, suspending agent, cosmetic base, slow-release incense releasing agent, mosquito repellent incense adhesive filler and adhesive agent all have attapulgite materials. I hope you can have more knowledge about it when applying, which is helpful to better practice.
