现代制皂法 总被引:1,自引:0,他引:1
目前,随着世界经济的发展,肥皂产量特别是香皂消费量逐年上升。为了生产更多更好的产品,获得更高的经济效益,肥皂厂家的规模越来越大,生产方法达到了一定的现代化水平,如美国现在每年的香皂产量已超过七十万吨。由于规模大、产量高,为采用最先进的生产技术创造了良好条件。1980年,利华公司在美国哈蒙德肥皂厂投资4300万美元巨资,建成一个全新的现代化香皂车间。从油脂处理、皂基制备、成型加工全部采用连续化生产,电子计算机自动控制和管理,使香皂生产达一个全新的高度。为配合我国香皂发展的需要,吸收国外先进技术,逐步更新、改造生产设备,走出我国的制皂工业现代化的新路,我们将在本讲座中从油脂预处理、皂基制备、成型加工等部分分别介绍国内外现代化制皂工艺。 相似文献

肥皂按商品形式可分为硬皂、软皂(皂膏)、液体皂三类。硬皂又分为洗衣皂、香皂、药皂等品种。根据应用情况来看,无机添加物中只有水玻璃是通用性的,几乎各种硬皂都有必要或多或少的添加之;其它无机添加物不通用,只适用于某些应用场合,亦不能同时使用。要更好地制皂添加物,就有必要了解其性状。在制皂添加物的应用问题中,人们最为关注的是应用场合、功用、用量这三方面的问题。 相似文献

Soap bacteriostats 总被引:2,自引:0,他引:2
Eric Jungermann 《Journal of the American Oil Chemists' Society》1968,45(5):345-350
The growing use of bacteriostats in soaps and the various methods for screening these com-pounds are reviewed critically.
Discussed are (1) in vitro techniques to establish antibacterial activity, substantivity tests using skin disk, fingerprint,
or radioactive tracer techniques, and microbiological availability determinations; (2) safety testing procedures; (3) in vivo
tests to determine deodorancy and degerming efficiency. Performance in clinical trials, designed to evalu-ate the contribution
of bacteriostatic soaps to the treatment of bacterially caused infections, is ex-amined. Discussed are studies on the control
of erythrasma, acne, diaper rash, and secondary cutaneous infections.
These techniques are illustrated by comparing two bacteriostatic systems, A and B, in soaps. System A contains 0.75% TCC and
0.75% hexa-chlorophene; System B contains 0.67% TBS, 0.67% TCC, and 0.67% Irgasan CF3. The data showed excellent correlation between in vitro screening techniques and actual in vivo per-formance characteristics. 相似文献

Many materials made from fats and oils derive their importance from their ability to modify the surface behavior of the liquid
in which they are dissolved. These compounds are grouped under the broad classification of surface active agents or surfactants.
Depending on their use, they are classified as detergents, wetting agents, emulsifiers, dispersing agents, etc. The oldest,
and still one of the most important surfactants, is ordinary soap; twentythree percent of all the tallow produced in the United
States goes into soap. This paper covers the present state of the art of soap technology, and the most important classes of
fat-based surfactants. 相似文献
