Summary
Personal care products containing formaldehyde may cause allergic reactions. This study re-examines formaldehyde-releasing ingredients like toluene sulfonamide formaldehyde resin and preservatives, including diazolidinyl urea and imidazolidinyl urea.
Area of Science:
- Dermatology
- Cosmetic Chemistry
- Toxicology
Background:
- Allergic contact dermatitis (ACD) is a significant concern associated with personal care products.
- Formaldehyde and formaldehyde-releasing agents are known allergens found in various consumer goods.
- Previous assessments may not fully reflect current understanding of specific formaldehyde-releasing substances.
Purpose of the Study:
- To re-evaluate personal care products implicated in formaldehyde-induced allergic contact dermatitis.
- To elucidate the chemistry of key formaldehyde-releasing ingredients.
- To review the utilization of formaldehyde in raw materials and as preservatives in cosmetics.
Main Methods:
- Chemical structure elucidation of toluene sulfonamide formaldehyde resin.
- Review of the chemical properties of diazolidinyl urea and imidazolidinyl urea.
- Analysis of formaldehyde release mechanisms from various cosmetic ingredients.
Main Results:
- Detailed chemical profiles of toluene sulfonamide formaldehyde resin, diazolidinyl urea, and imidazolidinyl urea were examined.
- Understanding of formaldehyde release from these compounds has advanced.
- Formaldehyde is incorporated into personal care products both as a raw material and via preservative systems.
Conclusions:
- Re-examination of formaldehyde-containing personal care products is warranted due to evolving chemical knowledge.
- Specific ingredients like toluene sulfonamide formaldehyde resin and formaldehyde-releasing preservatives require careful consideration in ACD assessments.
- Further research into the safe use and formulation of these ingredients is recommended.

01:16IUPAC Nomenclature of Aldehydes
Aldehydes are named based on the systematic nomenclature rules set by the IUPAC. For acyclic aldehydes, the longest carbon chain containing the aldehydic (–CHO) group is considered the parent chain. The aldehyde is named by replacing the last letter “e” in the hydrocarbon name with “al”. For instance, a simple, seven-carbon-membered acyclic aldehyde is called heptanal, derived from heptane. The carbon chain is numbered starting from the aldehydic carbon, although the aldehydic carbon’s locant...
01:32Aldehydes and Ketones with HCN: Cyanohydrin Formation Overview
Cyanohydrins are compounds that contain –CN and –OH groups on the same carbon atom. They are formed by the nucleophilic addition of the cyanide ions to the carbonyl group. Cyanide ions are highly basic and nucleophilic and can be generated from HCN under aqueous conditions. However, since HCN is a weak acid, the number of cyanide ions generated is very small. Hence, a small amount of base or KCN/NaCN is added to HCN to increase the concentration of the cyanide ions in the reaction mixture.
01:19Aldehydes and Ketones with Alcohols: Hemiacetal Formation
Similar to water, alcohols can add to the carbonyl carbon of the aldehydes and ketones. The addition of one molecule of alcohol to the carbonyl compound forms the hemiacetal or half acetal. As depicted below, in a hemiacetal, the carbon is directly linked to an OH and OR group.
01:36Types of Toxins
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

01:01Ketones with Nonenolizable Aromatic Aldehydes: Claisen–Schmidt Condensation
Benzaldehyde, like formaldehyde, lacks an α hydrogen and cannot enolize to form an enolate. Hence, the reaction of benzaldehyde with a ketone in the presence of an aqueous base forms a single crossed product. This reaction is referred to as Claisen–Schmidt condensation.
As the self-condensation of ketones is generally not favored in basic conditions, the self-condensed products do not form in the reaction between ketones and benzaldehyde. The general reaction of Claisen–Schmidt condensation is...

01:20Types of Step-Growth Polymers: Polyesters
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
