Acetone is a common solvent for use in laboratories because of its low cost and volatility, and as it does not form an azeotrope with water. For artistic purposes, when applied on the reverse of a laser print/ photocopy placed face-down on another surface and burnished firmly, the toner of the image gets transferred to the destination surface.
Sodium lauryl sulfate
Sodium lauryl sulfate is a surfactant, which means a molecule that has ampiphilic properties. This means the sulfate head group (shown by the pink shading in the diagram below) is hydrophilic and water soluble, while the 12-carbon-long chain is hydrophobic and water insoluble. It is an anionic surfactant as defined by the sulfate head group ...

As acetone was added to a ratio of acetone to water of 0.5:1 (v/v), the solubility value would be lowered to 20.9 ± 2.3 mg/mL. Almost no SS solid can be dissolved in the 1:1 (v/v) solution at 25 °C. It reveals that acetone …
Comparative study of saponin for surfactant properties and …
It showed that 0.6% crude saponins possessed moderate ing ability. The surface active properties of saponin were also compared with the synthetic surfactants such as sodium lauryl sulfate (SLS) and Tween 80. Surface tension of 0.6% solution of saponin, SLS and Tween 80 was determined as 37.39 mN/m, 26.15 mN/m and 37.18 mN /m …
Shampoo Science: A Review of the Physiochemical Processes …
[53, 81] The most common of the anionic surfactants are those containing sulfate groups such as sodium lauryl sulfate (SLS) or sodium lauryl ether sulfate (SLES) (Table 1). For the latter, the addition of ethoxylate groups helps to increase the surfactant skin mildness providing some mitigation for the irritation caused by sulfates.

Solubilization of drugs using sodium lauryl sulfate: Experimental data
Highlights. Micellar solubilization is a method for increasing drugs solubility. Sodium lauryl sulfate (SLS) is one of the common surfactants in pharmaceutical sciences. Solubility of various drugs was studied at two concentrations of SLS. The most of drugs showed an increase in solubility above the critical micelle concentration (CMC).
