Trolamine, an organic compound, is the salt formed between triethanolamine and salicylic acid. It is widely used as a topical analgesic. 10% trolamine salicylate medical products sold over-the-counter such as are creams for temporarily relief of minor aches and pains of muscles and joints associated with arthritis, simple backache, lumbago, neuralgia, strains, bruises, and sprains. The FDA approved in 1958 otic solution drops containing triethanolamine polypeptide used in the ear to break down and loosen earwax was discontinued. Trolamine can enhance skin healing by recruiting macrophages and modifying the concentrations of various immunomodulators. Trolamine (Biafine; Genmedix Ltd, France) is commonly prescribed at the beginning of radiotherapy for preventing acute radiation-induced skin toxicity in China. Biafine has been studied in radiodermatitis and Phase 2 clinical trial has been initiated in 2016 by Sun Yat-sen University to establish the efficacy of trolamine (Biafine) for the management of radiation dermatitis in patients with nasopharyngeal carcinoma receiving IMRT.

Diethanolamine (DEA) is an amino alcohol commonly used in the preparation of soaps and surfactants, agricultural chemicals and in textile processing. DEA and DEA-Derivatives are used in other products besides cosmetics and personal care products. For example, DEA and DEA-derivatives have been approved for several food-related applications, primarily food packaging.

Stearic Acid is a typical example of a fatty acid, which are essentially long hydrocarbon chains containing a carboxyl group at one end and a methyl group at the other. The chain lengths can vary from 3 (propionic acid) to 24 (lignoceric acid) but the majority of fatty acids found in hydrogenated vegetable or animal oils are around C16-C20 in length. Stearic acid is a saturated acid, since there are no double bonds between neighbouring carbon atoms. Stearic acid is found in various animal and plant fats, and is a major component of cocoa butter and shea butter. Stearic acid is a very common amino acid is used in the manufacturing of more than 3,200 skin and hair care products sold in the United States. On product labels, it is sometimes listed under other names, including Century 1240, cetylacetic acid, Emersol 120, Emersol 132, Emersol 150, Formula 300 and Glycon DP. Stearic Acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. Stearic acid is used along with castor oil for preparing softeners in textile sizing. Being inexpensively available and chemically benign, stearic acid finds many niche applications It is used in the manufacture of candles, and as a hardener in candies when mixed with simple sugar and corn syrup. It is also used to produce dietary supplements. In fireworks, stearic acid is often used to coat metal powders such as aluminum and iron. This prevents oxidation, allowing compositions to be stored for a longer period of time. Stearic acid is a common lubricant during injection molding and pressing of ceramic powders. It is also used as a mold release for foam latex that is baked in stone molds. Stearic acid is known antidiabetic and antioxidant agent.

Triethanolamine myristate is a fatty acid salt. It is used in cosmetics as emulsifier and surfactant. It may promote acne. Triethanolamine myristate was tested as gastrointestinal transit delaying agent. The investigations showed that in 4 out of 5 subjects, the gastric residence time of the pH-telemetering capsule could be prolonged and the renal elimination of riboflavin increased. The increase in renal elimination of riboflavin in the presence of triethanolamine myristate was statistically significant. In dogs, a bilayer tablet consisting of triethanolamine myristate and riboflavin resulted in an absolute bioavailability of 2-3 times greater than the bioavailability of riboflavin alone.
