TRIMYRISTIN is an inactive component of RODAN AND FIELDS ENHANCEMENTS used to prevent sunburns. TRIMYRISTIN is a constituent of nutmegs.

Sorbitan monopalmitate (Span 40) is a nonionic emulsifier, surfactant and food additive. The product of Croda Inc. Span 40 is used in skin care, hair care and decorative cosmetics. It is also used as an effector in compositions capable of facilitating penetration across a biological barrier. Inactive ingredient of some medications it improves transdermal delivery of drugs and is a potential carrier for topical drug delivery. In PLIAGLIS cream (lidocaine and tetracaine) sorbitan monopalmitate is used as an inactive ingredient. Sorbitan monopalmitate is a fatty acid sorbitan ester, yellowish brown wax, slightly soluble in isopropanol, xylene and liquid paraffin, insoluble in water, non-toxic.

Ethyl maltol, a key food additive, and flavor enhancer is safe and is the most common sweet-associated component in electronic cigarette liquids. Ethyl maltol binds to human serum albumin (HSA) by situating within subdomain IIA (site I) of HSA.

1,2,6-Hexanetriol is used as moisturizing agent (creams), as solvent (pharmaceuticals) and as crosslinker in plastics. There was mentioned, that this compound in fluocinonide cream could cause allergic contact dermatitis.

Parabens are widely used preservatives in basic necessities such as cosmetic and pharmaceutical products. It was found, that butylparaben has estrogenic and antiandrogenic properties and is known to reduce sperm counts in rats following perinatal exposure. In addition was observed, that butylparaben exerted endocrine disrupting effects on both male and female offspring. In 2009-2010, 80 pregnant women from Ottawa Canada participated in the Plastics and Personal-Care Product Use in Pregnancy (P4) Study. Women kept a diary of products that they used 24 h prior to and during the collection. All parabens measured in maternal urine had moderate to high reproducibility. Women who used lotions in the past 24 h had significantly higher geometric mean paraben concentrations (80-110%) in their urine than women who reported no use in the past 24 h. Women who used shampoo, conditioner, and cosmetics also showed 70-80% higher butylparaben concentrations in their urine.

Butylated hydroxytoluene, commonly known as BHT, is an organic compound that is used in the food, cosmetic, and pharmaceutical industry as an antioxidant. BHT is a substituted derivative of phenol. BHT helps to prevent the formation of free radicals and oxidation. When used in food products, it delays oxidative rancidity of fats and oils, and prevents loss of activity of oil-soluble vitamins. It may be found in pharmaceutical gels, creams and liquid or gelatin capsules, tablets and other pharmaceutical dosage forms. The ability of oral BHT to lead to cancer is a controversial topic, but most food industries have replaced it with butylated hydroxyanisole (BHA). BHT was first used as an antioxidant food additive in 1954. BHT does have other commercial uses, as in animal feeds and in the manufacture of synthetic rubber and plastics, where it also acts as an antioxidant. The U.S. Food and Drug Administration has deemed that BHT is safe enough when used in limited concentrations. It currently permits its use in concentrations of about 0.01% to 0.02% in most foods. As an emulsion stabilizer in shortening, it may be used in a somewhat higher concentration, 200 parts per million.

Isopropyl Isostearate is the ester of Isopropyl Alcohol and Isostearic Acid used in beauty products as an emollient, skin conditioning agent, binder and humectant. Isopropyl Isostearate is ideal for heat sensitive personal care formulations. It enables superior odour and colour end-products. It also exhibits excellent skin feel without feel of greasiness.

GLYCERYL RICINOLEATE is a monoester of glycerin and ricinoleic acid. In cosmetic formulations Glyceryl ricinoleate can have the following functions: emulsifier/co-emulsifier, refatting agent, dispersing aid. But the primary function of Glyceryl ricinoleate is a skin protection agent. Glyceryl ricinoleate is used in nearly all skin care preparations such as creams, lotions, bath oils, shaving formulations, refatting soap and shower agents in amounts of 2 – 10%. In an epicutaneous test and after long use in cosmetic preparations, no irritations were observed.

Readily soluble in water, SnF2 is hydrolysed. At low concentration, it forms species such as SnOH+, Sn(OH)2 and Sn(OH)3−. At higher concentrations, predominantly polynuclear species are formed, including Sn2(OH)22+ and Sn3(OH)42+. Aqueous solutions readily oxidise to form insoluble precipitates of SnIV, which are ineffective as a dental prophylactic. Tin(II) fluoride, commonly referred to commercially (with tin(II) in Latin) as stannous fluoride, is a chemical compound with the formula SnF2. It is a colorless solid used as an ingredient in toothpastes that are typically more expensive than those that use sodium fluoride. Stannous fluoride has both bactericidal and bacteriostatic properties, which fight plaque and treat/prevent gingivitis. The stannous fluoride also deposits a protective mineral barrier over exposed dentinal tubules to help prevent sensitivity pain from triggers such as hot or cold liquids and foods. Stannous fluoride is used under the trade name "Fluoristan" in the original formulation of the toothpaste Crest, though it was later replaced with sodium monofluorophosphate, or "Fluoristat". It is the active ingredient in Crest Pro Health brand toothpaste. Crest Pro Health issues a warning on the tube that stannous fluoride may cause staining, which can be avoided by proper brushing, and that its particular formulation is resistant to staining. Any stannous fluoride staining that occurs due to improper brushing is not permanent. Stannous fluoride is also used in Oral-B Pro-Expert. Stannous fluoride is also readily available in over-the-counter rinses.
