When mixed in equimolar proportions with a fatty acid, such as stearic acid or oleic acid, triethanolamine forms an anionic soap with a pH of about 8, which may be used as an emulsifying agent to produce fine-grained, stable oil-in-water emulsions. Concentrations that are typically used for emulsification are 2-4% v/v of triethanolamine and 2-5 times that of fatty acids. In the case of mineral oils, 5% v/v of triethanolamine will be needed, with an appropriate increase in the amount of fatty acid used. Preparations that contain triethanolamine soaps tend to darken on storage. However, discoloration may be reduced by avoiding exposure to light and contact with metals and metal ions.

Sodium (Na" ") and potassium (K" ) carboxylate salts of fatty acids are used as soaps. Fatty acids, the carboxylic acids derived from fats, are mixtures of unbranched carboxylic acids of 14 to 20 carbons (Chap. 19).

In addition to the fatty acids and their metal soaps, fatty acid esters and fatty alcohols are used, because they give outstanding processing improvements but without other types of action—for example, cure and activation or breakdown enhancement during the mastication of NR or IR. Pentaerythritol tetrastearate is a example of an ester-type process aid with a broad range of applications. It does not bloom or exert unwanted effects.

Sulfolane, another highly polar solvent, is used to separate aromatic hydrocarbons from aliphatic hydrocarbons [10]. The extraction process first developed by Shell Oil in 1959 and which is referred to as the Sulfolane process is used worldwide. The solvency of sulfolane for certain fatty acids and fatty acid esters is the basis for upgrading animal and vegetable fatty acids used in food products, paints, plastics, resins, and soaps. Aqueous solutions containing 30-70 wt% sulfolane are used to remove lignin from wood chips [11]. Sulfolane is used to remove acidic components like hydrogen sulfide and carbon dioxide from gas feed stocks. 

Stearic acid C17H35COOH. A solid saturated fatty acid found in many fats and oils. It is one of the fatty acids used in soap manufacture. 

Soaps, fatty acids, and perfumes are susceptible to oxidation during aging (25). The oxidation process is quite complex but typically results from the reaction of the unsaturated bonds in these components with oxygen in the air, resulting in the formation of shorter chain-length acids, aldehydes, and ketones which are extremely odoriferous. In the case of perfume components, oxidation can produce a change in product odor character and cause discoloration of the bar. To minimize the oxidation of the base soap and other minor ingredients in soap bars, both chelants and antioxidants are commonly used. 

Whether an additive acts as a lubricant or mold release agent depends on many factors, including its structure and also the type and plastic material in question. The lubricating effect and the mold release effect are often developed at the same time. Metal soaps, fatty acid esters and fatty acid amides are generally used as lubricants for relatively apolar plastics, such as polyethylenes and polypropylenes. Relatively polar plastics, such as polyesters, polycarbonates, polyamides, PVC, polystyrene and ABS, generally need both lubrieants and mold release agents. Suitable mold release agents are fatty acid amides, metal soaps, polyethylene... 

The standard spectra are run using pure compounds and include the common organic reagents. The commercial series includes dyes, stains, plasticizers, monomers, polymers, polyols, resins, rubbers, soaps, fatty acids and drying oils, solvents, surface-active agents, textile chemicals, waxes, petroleum chemicals, intermediates, and pharmaceuticals. These spectra reflect the materials as they are available commercially, and list their trade as well as chemical names. 

Consider palmitic acid, C16H32O2, a common fatty acid used in the manufacture of soap. A solution of palmitic acid is prepared by mixing 112 g of palmitic acid with 725 mL of benzene, C Hs (d = 0.879 g/mL). The density of the resulting solution is 0.902 g/mL.
