摘要:
Alkyl glycosides are used to greatly increase the microbicidal activity of biguanide compounds, such as chlorhexidine salts. The alkyl glycoside/biguanide agents have a particular utility in teeth cleaning preparations due to their improved microbicidal activity against gram-positive bacteria.
摘要:
Detergents on the basis of anionic and nonionic surfactants contain as laundering power-enhancing additives an aliphatic amine compound which is selected such that its pK.sub.b value is at least equal to 14, minus the initial pH value of a 1% aqueous solution of the detergent containing the amine compound. Laundering power-enhancing amine compounds selected according to the rule mentioned are certain ether amines, amidoamines, glucamine derivatives or morpholine derivatives.

摘要:
This invention is directed to a process for the production of extracts from spices in two stages by extraction with a non-toxic gas as solvent, the improvement which comprises in a first stage extracting from the spices essential oils functioning as aroma components by contacting the spices with liquid solvent, at a pressure in the supercritical range and a temperature in the subcritical range, separating the solvent from the spice, evaporating the solvent and separating essential oils, and in a second stage extracting from the spices the portions acting as flavor carriers by contacting the spices from the first stage with gaseous solvent, at a pressure and a temperature both in the supercritical range, separating the gaseous solvent from the spice, reducing the pressure and temperature, and separating the flavor carriers from the gaseous solvent.
