DMDM Hydantoin DMDM Hydantoin You have shown a positive allergic reaction to DMDM hydantoin. Information about this substance is below. What is it? DMDM Hydantoin is a preservative which kills fungi, yeast & bacteria. Preservatives are a way to ensure that our cosmetics and personal care products are safe. Without preservatives, products can spoil or become contaminated with bacteria. DMDM hydantoin is found primarily in cosmetic products. How can I avoid it? Skin contact with DMDM Hydantoin is required for it to cause a rash. Discontinuation of exposure to products containing DMDM Hydantoin should result in improvement and/or resolution of your dermatitis. The most common cause of allergic contact dermatitis from DMDM Hydantoin is cosmetics preserved with this chemical. By law, all products made in the US for topical use have the in- gredients listed either on the product package or the box that contains it, so check the labeling of ingredients in your cosmetics. At work, request a material safety data sheet (MSDS) to help identify potential sources of exposure. Some individuals who are allergic to formaldehyde are also sensitive to DMDM Hydantoin, since DMDM Hydantoin releases small amounts of formaldehyde. DMDM Hydantoin sensitive individuals may need to avoid preserved with formaldehyde or formaldehyde- releasing agents, such as: • Diazolidinyl Urea • Imidazolidinyl urea (Germall) • 2-bromo-2-nitropropane-1,30diol (Bronopol) • Quaternium-15 • Tris nitromethane (Tris Nitro) Tris Nitro is an industrial biocide and is not usually found in skin, hair or cosmetic product Uses: Here is a partial list of products known to have contained DMDM Hydantoin in the past. • Adhesives • Antiarrhythmic and anticonvulsive agents • Color photography/Copying paper • Cutting oils • Floor waxes • Herbicides • Inks • Latex paints • Polymers and plastics • Pet Products • Skin Care Products/Cosmetics ° Hair care products ° Hair Colorants/“Permanents-Relaxers” ° Soaps/Cleansers/household detergents ° Shampoos/Conditioners ° Moisturizers/lotions ° Baby soaps and cleansers ° Make-ups ° Powders/Sprays ° Shaving products ° Sunscreens ©2019 Mayo Foundation for Medical Education and Research Page 1 of 2 MCS7562-157rev0819 DMDM Hydantoin (continued) • Medications, topical, prescription and over the counter such as ° Anesthetics ° Antiseptics ° Creams, Ointments, Solutions ° Foot and other powders ° Nasal decongestants ° Traditional Chinese Medications ° Wound dressings • Textile sizing agents Other names for DMDM Hydantoin: • Glydant® • Glydant Plus® (95:5 mixture of DMDM and iodo propynyl) • Dimethyloldimethyl hydantoin • 1,3 dimethylol-5,5-dimethyl hydantoin • Dantoin DMDMH • DMDMH • Mackstat DM • Nipaguard DMDMH • 1,3-Bis(hydroxymethyl)-5,5-dimethyl-4-imidazolidine-2,4-dione(+) • 2,4-imidazolidinedione, 1,3-bis(hydroxymethyl)-5,5-dimethyl- • 1,3-Bis(hydroxymethyl)-5,5-dimethyl-2,4-imidazolidinedione • 1,3-Di(hydroxymethyl)-5,5-dimethylhydantoin • Glycoserve-DMDMH • Hydantoin,1,3-bis(hydroxymethyl)-5,5-dimethyl- Potential cross-reacting/co-reacting substances: • Formaldehyde • Quaternium-15 • Imidazolidinyl urea • Diazolidinyl Urea • 2-bromo-2-nitropropane-1,3-diol (Bronopol) • Dimethylol dihydroxyethyleneurea Page 2 of 2 MCS7562-157rev0819.

Undeclared Formaldehyde Levels in Patient Consumer Products: Formaldehyde Test Kit Utility Jason E. Ham1, Paul Siegel1,*, and Howard Maibach2 1Health Effects Laboratory Division, National Institute for Occupational Safety and Health, Morgantown, WV, USA 2Department of Dermatology, School of Medicine, University of California-San Francisco, San Francisco, CA, USA Abstract Formaldehyde allergic contact dermatitis (ACD) may be due to products with free formaldehyde or formaldehyde-releasing agents, however, assessment of formaldehyde levels in such products is infrequently conducted. The present study quantifies total releasable formaldehyde from “in-use” products associated with formaldehyde ACD and tests the utility of commercially available formaldehyde spot test kits. Personal care products from 2 patients with ACD to formaldehyde were initially screened at the clinic for formaldehyde using a formaldehyde spot test kit. Formaldehyde positive products were sent to the laboratory for confirmation by gas chromatography-mass spectrometry. In addition, 4 formaldehyde spot test kits were evaluated for potential utility in a clinical setting. Nine of the 10 formaldehyde spot test kit positive products obtained from formaldehyde allergic patients had formaldehyde with total releasable formaldehyde levels ranging from 5.4 to 269.4 μg/g. Of these, only 2 shampoos tested listed a formaldehyde-releasing agent in the ingredients or product literature. Subsequently, commercially available formaldehyde spot test kits were evaluated in the laboratory for ability to identify formaldehyde in personal care products.

All rights reserved CONTACT DERMATITIS Review Article Formaldehyde-releasers: relationship to formaldehyde contact allergy. Contact allergy to formaldehyde and inventory of formaldehyde-releasers 1 2 1 3 1 Anton C de Groot , Mari-ann Flyvholm , Gerda Lensen , Torkil Menne´ AND Pieter-Jan Coenraads 1Department of Dermatology, University Medical Center Groningen, University of Groningen, 9700 RB Groningen, The Netherlands, 2National Research Centre for the Working Environment, Lerso Parkalle´ 105, DK-2100 Copenhagen, and 3Gentofte Hospital, Dermato-Allergology Department K, Niels Andersens Vej 65, 2900 Hellerup, Denmark This is one of series of review articles on formaldehyde and formaldehyde-releasers (others: formaldehyde in cosmetics, in clothes and in metalworking fluids and miscellaneous). Thirty-five chemicals were identified as being formaldehyde-releasers. Although a further seven are listed in the literature as formaldehyde-releasers, data are inadequate to consider them as such beyond doubt. Several (nomenclature) mistakes and outdated information are discussed. Formaldehyde and formaldehyde allergy are reviewed: applications, exposure scenarios, legislation, patch testing problems, frequency of sensitization, relevance of positive patch test reactions, clinical pattern of allergic contact dermatitis from formaldehyde, prognosis, threshold for elicitation of allergic contact dermatitis, analytical tests to determine formaldehyde in products and frequency of exposure to formaldehyde and releasers. The frequency of contact allergy to formaldehyde is consistently higher in the USA (8–9%) than in Europe (2–3%). Patch testing with formaldehyde is problematic; the currently used 1% solution may result in both false-positive and false-negative (up to 40%) reactions.

  • A New Route to the Imidazole-2-Thiones from 2-Thiohydantoins IMPLICATIONS in the STUDY of ERGOTHIONEINE
    Biochem. J. (1968) 109, 209 209 Printed in Great Britain A New Route to the Imidazole-2-thiones from 2-Thiohydantoins IMPLICATIONS IN THE STUDY OF ERGOTHIONEINE BY J. E. SCOTT AND GILLIAN HENDERSON Medical Re8earch Council Rheumati8m Research Unit, Canadian Red Cro88 Ho8pital, Taplow, Maidenhead, Berk8. (Received 4 March 1968) 1. 2-Thiohydantoins are reduced by borohydrides to 4(5)-hydroxyimidazolidine- 2-thiones, which eliminate water in acid to form imidazole-2-thiones. Both steps take place in mild conditions, in high yield. A number of imidazole-2-thiones have been synthesized by this sequence of steps, with one, two or three substituents in the 1-, 3- and 4(5)-positions. 2. 4(5)-Hydroxyimidazolidine-2-thiones are am- monium pseudo-bases, giving rise to an equilibrium mixture of amino aldehyde, carbinolamine and mesomeric ammonium cationic forms. The elimination of water is suggested to be a property of the mesomeric ammonium cation. 3. The mild conditions in which imidazole-2-thiones are formed from 4(5)-hydroxy- imidazolidine-2-thiones are similar to those in which ergothioneine, a naturally occurring imidazole-2-thione of uncertain function, is normally released and measured. It is suggested that the occurrence in vivo ofa precursor to ergothioneine, in the form ofa 4(5)-hydroxyimidazolidine-2-thione, would explain many otherwise conflicting published data. Tmidazole-2-thiones are usually prepared by thiohydantoin of glucosaminic acid with sodium heating a-thiocarbamido derivatives of acetals and borohydride (Scott, 1964; Scheme 1: R = D-arabino- ketones in strong acid (the Wohl-Marckwald tetrahydroxybutyl, R' = H, R" = phenyl).
