Abstract
In this research, three types of surfactants were used: the first type is Sodium
Dodecyl Sulfate SDS, the second type is commercial soap, and the third type is
laboratory-prepared soap.
Three soaps with different proportions were placed in a test tube containing an
equal proportion of oil and water
The samples were divided into two phases, one containing the original water
salinity and the other containing the water salinity diluted to half.
By exposing the samples to a different temperature, a layer of microemulsion
was formed in both the soap that was prepared in the laboratory and the commercial
soap. It was found that the first type of Sodium Dodecyl Sulfate SDS sulfactan mixed
oil with water, and the microemulsion layer did not form.
