Among specific topics are the wettability of solid-supported lipid layers, interfacial studies of coffee-based beverages from flavor perception to biofuels, the structure and function of hydrotropes
, and soil removal by surfactants during cleaning processes.
are a class of chemical compounds which affect an increased aqueous solubility by several folds to certain solutes which are sparingly soluble in water under normal conditions.

Key statement: Aqueous dispersions of silicone oils are prepared without the need for surfactants, solvents, hydrotropes
or emulsifiers by employing water soluble and/or water dispersible polymers providing inventive compositions which exhibit a rheological critical strain value greater than zero and less than about 0.5.
Stream 3 was from a firm manufacturing detergent alkylates, hydrotropes
, and petroleum detergent intermediates.
* Detergents, solvents and hydrotropes
for hard surface cleaning, industrial and institutional (I&I) cleaning, and vehicle care
* US Patent 8,921,295 B2; American Sterilizer Company, Mentor, OH, has patented a concentrated neutral detergent composition that is comprised of one or more nonionic surfactants, comprising a primary or a secondary alcohol ethoxylate, an alcohol alkoxylate other than said ethoxylate, an aromatic ethoxylate, a modified ethoxylate, or a block polymer of propylene oxide and ethylene oxide, or any combination thereof; one or more hydrotropes
comprising an amine oxide, or a glucoside, or both; one or more chelants; a buffer comprising one or more alcohol amines, or one or more organic acids, or any combination thereof; one or more corrosion inhibitors comprising an amine, amidazole, diazole, triazole, carboxylic acid, or any combination thereof; and water.
Optionally, it can also contain one or more of the following adjuncts selected from the group consisting of: builders, buffers, fragrances, perfumes, thickeners, dyes, colorants, pigments, foaming stabilizers, water-insoluble organic solvents, corrosion inhibitors, hydrotropes
, and mixtures thereof.
of a co-surfactant constituent selected from the group consisting of nonionic, cationic, amphoteric, zwitterionic surfactants, and mixtures thereof; one or more constituents selected from the group consisting of coloring agents, fragrances and fragrance solubilizers, viscosity modifying agents thickeners, pH adjusting agents and pH buffers, optical brighteners, opacifying agents, hydrotropes
, abrasives, and preservatives; and water.
* In the household and industrial and institutional (HII) segment, Solvay offers a broad range of products including sodium percarbonate, hydrogen peroxide, paracetic acid and sodium carbonate, as well as soil release and surface modification polymers, hydrotropes
, mild amphoteric surfactants and green non-toxic solvents.
"The Clariant Detergents & Intermediates business ideally complements our fine chemicals and custom manufacturing operations, providing also the basis for a new detergents platform together with our US hydrotropes
and batch sulfonation business of Nease Corp," said ICIG managing director Achim Riemann.
