The chemical structure of the conventional Neuberg's hydrotropic salts (proto-type, sodium benzoate) consists generally of two essential parts, an anionic group and a hydrophobic aromatic ring or ring system. The anionic group is involved in bringing about high aqueous solubility, which is a prerequisite for a hydrotropic substance.
Sodium nonanoyloxybenzenesulfonate (NOBS) is an important component of laundry detergents and bleaches. It is known as a bleach activator for active oxygen sources, allowing formulas containing hydrogen peroxide releasing chemicals (specifically sodium perborate , sodium percarbonate , sodium perphosphate , sodium persulfate , and urea peroxide ...

The sulfonate ion. In organosulfur chemistry, a sulfonate is a salt, anion or ester of a sulfonic acid. Its formula is R−S(=O) 2 −O −, containing the functional group −S(=O) 2 −O −, where R is typically an organyl group, amino group or a halogen atom. Sulfonates are the conjugate bases of sulfonic acids.
Sodium benzenesulfonate is an organic compound with the formula C 6 H 5 SO 3 Na. It is white, water-soluble solid, It is produced by the neutralization benzenesulfonic acid with sodium hydroxide. It is also a common ingredient in some detergents. The compound typically crystallizes from water as the monohydrate. [1]
The physical properties of the isomers of xylene differ slightly. The melting point ranges from −47.87 °C (−54.17 °F) (m-xylene) to 13.26 °C (55.87 °F) (p-xylene)—as usual, the para isomer's melting point is much higher because it packs more readily in the crystal structure. The boiling point for each isomer is around 140 °C (284 °F).
Sodium laurylsulfate tested on Uronema parduczi, a protozoan, was found to have the lowest effect value with the 20 h-EC5 being 0.75 milligrams per litre (2.7 × 10 −8 lb/cu in). Chronic exposure tests with C 12 to C 18 with the invertebrate Ceriodaphnia dubia found the highest toxicity is with C 14 ( NOEC was 0.045 mg/L).
The structure of a sulfone Dimethyl sulfone, an example of a sulfone. In organic chemistry, a sulfone is a organosulfur compound containing a sulfonyl (R−S(=O) 2 −R’) functional group attached to two carbon atoms.
