前言評定香皂質量的好坏,不外乎二方面:(一)皂基質量,(二)感官質量。皂基的質量是比較容易掌握的,只要謹慎选擇油脂,有条件的厂可以进行精制漂煉,接着对煮皂过程的每个工序加强控制和小心操作,皂基質量就不难达到指标的要求。感官質量包括外观、形狀、色泽和香味,其中外观、形狀和色泽質量的工艺过程比較簡單覀冊诤嫫枇稀⒛肽ァ⒀固酢⑶锌椤⒋蛴∫约鞍b等工序,只要做到謹慎操 相似文献

Summary Hexachlorophene is determined in soap by measuring the color produced by reaction with ferric chloride in alcohol solution
with controlled conditions of time and temperature. The precision is within ±5% of the hexachlorophene content at the 1/2%
level or above. As a criterion, any soap that will give a finely dispersed barium soap and that does not form a precipitate
with ferric chloride under the conditions of the method give good results. This includes all milled bar soaps. The effect
of phenolic perfume ingredients on the result is negligible. Five per cent abietic acid in the fatty acid composition has
no effect on the result. The method is slightly modified for use with liquid potassium soaps. 相似文献

涂膜老化试验变色等级评定中的测量误差 总被引:1,自引:1,他引:0
在评定涂膜老化实验过程中的变色等级时有多种不同的测定方法。分析了目视评价和几种仪器测量方法之间的误差,指出现有测量方法标准中存在的问题,建议采用定向型(45°/0°或0°/45°)的颜色测量仪器,以ΔECMC代替ΔE*ab作为色差值的量度,从而解决涂膜变色等级评定中的不一致性问题。 相似文献

Resistance of soap to hardness of water as reflected by its ability to lather in hard water has been tried as as analytical parameter to assess the quality and hence effectiveness of the soap. The resistance of a soap to hardness of water can be considered to be the sum total effect of four factors: 1. Composition of the fat base, 2. solubility of the soap at the washing temperature, 3. polymorphism of soap crystals and 4. nature and proportions of additives in the soap. The method thus helps in assessing the quality of the soap with regard to these factors and in working out the economics of its use. 相似文献

An AutoAnalyzer method has been developed to determine free alkalinity or acidity in soap by use of a mixed cresol red-phenolphthalein indicator solution and by measurement of the color developed at 550 mµ. An internal standard or reference solution is used consisting of a soap solution which has been adjusted to represent neutrality. The method was applied for 0 to 0.10% free alkalinity, calculated as sodium hydroxide, and for 0 to 0.50% free acidity calculated as oleic acid. Attainable precision of the method (95% confidence limits) in the ranges explored was found to be ±0.0025% for free alkali and ±0.05% for free acidity. 相似文献
