BS 3762-3.6:1986

This standard BS 3762-3.6:1986 Analysis of formulated detergents is classified in these ICS categories:

• 71.100.40 Surface active agents

This Section of BS 3762 describes a method for the determination, in formulated detergents, of the matter soluble in light petroleum.

The matter soluble in light petroleum usually consists of unreacted fatty alcohols or hydrocarbons, but it may also contain added fatty matter and perfume.

Unreacted fatty matter from ingredients such as mono-glyceride sulphate or alkanolamide sulphate is not extracted with light petroleum, and ethoxylated alcohols, either added deliberately or present as unsulphated matter, are only partially extracted. These compounds can be determined, if desired, using the method described in BS 3762-3.7.

NOTE The titles of the publications referred to in this Section are listed on the inside back cover.
