1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Safety of 1-Chlorooctadecane

Synthesis and properties of stearylhexylmethyl carboxyl betaine was written by Song, Hong-juan;Song, Bing-lei;Cui, Zheng-gang;Xu, Li-jun. And the article was included in Jingxi Huagong in 2015.Safety of 1-Chlorooctadecane This article mentions the following:

In order to gain insights into the effects of mol. structure on the properties of surfactants, an asym. double long-chain alkyl betaine, stearylhexylmethyl carboxyl betaine (C18+6B), was synthesized using stearic acid and hexanoic acid as starting materials and its surface activity was measured and compared with that of didodecyl Me carboxyl betaine (diC12B), a sym. double long-chain betaine with equal total carbon number The results showed that C18+6B had a surface activity similar to that of diC12B in general, but displays an aqueous solubility much better than that of diC12B. As a surfactant for surfactant-polymer flooding free of alkali, C18+6B seemed to be slightly less hydrophobic against Daqing crude oil, which solely could reduce the Daqing crude oil/connate water interfacial tension (IFT) to 10-2 mN/m magnitude and gave a saturated adsorption 30% lower than that of diC12B at Daqing sandstone/water interface at 45°C. C18+6B solely could reduce C7-C9 n-alkanes/connate water IFT to 10-3 mN/m magnitude at 45°C, and could reduce the Daqing crude oil/connate water IFT to 10-3 mN/m magnitude at 45°C by mixing with the more hydrophobic surfactant diC12B and other hydrophilic betaine surfactant, where the aqueous solubility of the formulation was greatly improved by the presence of C18+6B. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Safety of 1-Chlorooctadecane).
