α-Olefin sulfonates with linear alkenyl radicals from C 12 to C 18 are used as anionic surfactants in various areas of application due to their pronounced foam formation [clarification needed] and foam stability (even with high water hardness), excellent fat-dissolving power and oil dissolving power as well as a favorable ecological profile and low aquatic toxicity and human toxicity.
Alkyl (C14-C16) olefin sulfonate, sodium salt: Car wash, dog shampoo, emulsifier 9016-45-9: Alkylphenol ethoxylate surfactants: Engine cleaner, rubber sealant, emulsifier 1327-41-9: Aluminum chloride: Antiperspirant 73138-27-9: Amines, C12-14-tert-alkyl, ethoxylated: No record 71011-04-6: Amines, ditallow alkyl, ethoxylated: No record 68551-33-7
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 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.
Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12-C 15, C 12-C 13 and C 10-C 13, for detergent use. [1] The C n H 2n+1 chain is unbranched. They are mainly produced as intermediate in the production of surfactants, for use in detergent. Since the 1960s, LABs have emerged as the dominant precursor of ...
Straight-chain terminal alkenes, also called linear alpha olefins (LAO) or normal alpha olefins (NAO), are alkenes (olefins) having a chemical formula C n H 2n, distinguished from other alkenes with a similar molecular formula by being terminal alkenes, in which the double bond occurs at the alpha (α-, 1-or primary) position, and by having a linear (unbranched) hydrocarbon chain.
C12-C14 alcohol glycidyl ether (AGE) is an organic chemical in the glycidyl ether family. [2] It is a mixture of mainly 12 and 14 carbon chain alcohols, also called fatty alcohols that have been glycidated. It is an industrial chemical used as a surfactant but primarily for epoxy resin viscosity reduction. [3]
An example of a linear alkylbenzene sulfonate (LAS) Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways. [2] In the most common route benzene is alkylated by long chain monoalkenes (e.g. dodecene) using hydrogen fluoride as a catalyst. [9]
