Resources by Unilever

This Unilever Laboratory Experiment, published in 1966, demonstrates that mineral oil and water form an oil-in-water emulsion when sodium oleate is the emulsifier, and a water-in-oil emulsion when calcium oleate is the emulsifier. Water-soluble and oil-soluble dyes are used to distinguish the two types of emulsion...

N-terminal Analysis of a Dipeptide

This Unilever Laboratory Experiment, published in 1967, describes a procedure based on the use of 1 -fluoro 2,4 dinitrophenylation (FDNB) as developed by Sanger during his studies on the structure of the protein hormone insulin. In the experiment, two dipeptides are used which contain the same two amino acids but...

This Unilever Laboratory Experiment describes the preparation of soap from a mixture of cooking oil and dripping. The leaflet was first published in 1964 and so lacks modern safety guidance. The procedure is authentic; it is designed to produce a convincing sample of soap. This means that it could be the basis of...

The method of preparation of a sulphonate paste described in this Unilever Laboratory Experiment is basically the same as that used by Unilever in the large-scale production of soapless detergents at the time of publication in 1964. The required reactants included an alkylbenzene hydrocarbon supplied by the...
