\nSources of formaldehyde<\/strong><\/td>\n<\/tr>\n\n\n\n- Fabrics treated with formaldehyde resins and in which some free formaldehyde remains. Formaldehyde resins provide the unique qualities of the following fabrics:\n
\n- Permanent ironing<\/li>\n
- Non-stick, anti-static, anti-wrinkle and anti-shrink finishes<\/li>\n
- Chlorine resistant finishes.<\/li>\n
- Stiffness in light nylon fabrics<\/li>\n
- Waterproof finishes<\/li>\n
- Sweat-proof finishes<\/li>\n
- Moth and mildew proof finishes<\/li>\n
- Suede and suede<\/li>\n<\/ul>\n<\/li>\n
- Cosmetics and toiletries, such as nail polishes and hardeners, antiperspirants, makeup, bubble bath, bath oils, shampoos, creams, mouthwashes and deodorants. In many cases, formaldehyde is used as a preservative.<\/li>\n
- Household cleaners, disinfectants and rinse aids<\/li>\n
- Paper products: formaldehyde is used to improve water resistance, grease resistance, shrinkage resistance and other characteristics of paper<\/li>\n
- Building Materials: Urea-formaldehyde glue or adhesive is used on pressed wood products, such as particleboard, plywood, and MDF<\/li>\n
- Medications including wart remedies, anhydrotics, medicated creams, orthopedic<\/span> plaster and disinfectant for root canal preparation<\/li>\n
- Paints, primers and mold release agents.<\/li>\n
- Embalming fluid and as a preservative for laboratory samples.<\/li>\n
- Formaldehyde is released in smoke from burning wood, coal, charcoal, cigarettes, natural gas and kerosene.<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
<\/span>What are the reactions to formaldehyde?<\/span><\/h2>\nReactions to formaldehyde depend on the type of exposure that has occurred. Formaldehyde is not only a sensitizer but also a potent primary<\/span> irritating<\/span>. Exposure to formaldehyde gas can cause burning sensations in the eyes, nose and throat, rashes, chest tightness and wheezing, fatigue and headaches. These symptoms may be the result of a primary irritant effect or an allergy. sensitization<\/span> to formaldehyde<\/p>\nFrequent or prolonged exposure may cause hypersensitivity<\/span>, leading to the development of allergic contact dermatitis<\/span>. Formaldehyde was declared contact Allergens<\/span> of the year 2015 by the American Contact Dermatitis Society (ACDS).<\/span><\/p>\nAllergy<\/span> Formaldehyde can occur through skin products that contain formaldehyde or with clothing made from fabrics that contain formaldehyde. Dermatitis caused by clothing tends to affect the parts of the body where there is the most friction between the skin and the fabric, for example, \u201ctrouser dermatitis\u201d usually appears on the inner thighs. gluteus<\/span> folds and back of the knees. Sweating can also be a factor that causes allergic dermatitis such as sweat or tallow<\/span> appears to leach free formaldehyde from formaldehyde resins. Formaldehyde-sensitive people are not necessarily hypersensitive to formaldehyde resins. Clothing dermatitis is reported to affect women more than men.<\/p>\nIn very sensitive people, contact with small amounts of formaldehyde, or being in a room where a bottle of formaldehyde may have been previously opened, leaving residual gases, can cause dermatitis.<\/p>\n\n\n \n  \n<\/div>\n Patch tests<\/p>\n<\/p><\/div>\n<\/section>\n <\/div>\n \n \n \n \n<\/div><\/div><\/div><\/div>\n <\/span>Am I allergic to formaldehyde?<\/span><\/h2>\nFormaldehyde allergy is diagnosed based on clinical history and by performing patch<\/span> tests<\/p>\nFormalin patch test (40% solution<\/span> of gaseous formaldehyde) is carried out using an aqueous solution of formalin at 2%. Some researchers have stated that the 75% of positive patch tests have no clinical significance and only the 20% of these may be related to real cases of formaldehyde dermatitis.<\/p>\nThe diagnosis of clothing dermatitis due to free formaldehyde can only be confirmed if the following standard criteria are met. In some cases, clothing dermatitis may not be a problem, even if the suspected fabric tests positive for free formaldehyde and an individual has a positive patch test reaction to formalin 2%.<\/p>\n \n\n\nDermatitis in formaldehyde clothing: criteria to meet<\/strong><\/td>\n<\/tr>\n\n\n\n- Suspicious fabric shows presence of free formaldehyde<\/li>\n
- Patient shows a positive patch test reaction to formalin 2%<\/li>\n
- Fabric impregnated with formaldehyde resin shows a positive reaction in the patch test: the tested piece of fabric must have been worn and subjected to sweat, sebum and friction<\/li>\n
- Wearing the fabric causes clinical allergic contact dermatitis.<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Product patch testing for formaldehyde resins is performed using 10% of urea formaldehyde in Vaseline, 10% of melamine formaldehyde in Vaseline, and 1% of other formaldehyde resins in Vaseline or isopropyl alcohol.<\/p>\n A product self-test for formaldehyde should be performed only with products designed to remain on the skin, such as cosmetics and lotions. Apply a small amount of the product to a small sensitive area of skin, such as the crook of your arm or neck. Examine the area every day for several days and if no reaction occurs, the product is likely suitable for use.<\/p>\n <\/span>Treatment of contact dermatitis due to exposure to formaldehyde<\/span><\/h2>\nIf you are diagnosed with a formaldehyde allergy, if possible, avoid exposure to products containing formaldehyde; otherwise, take steps to reduce potential exposure.<\/p>\n Once dermatitis appears on the skin, treatment is like any other. acute<\/span> dermatitis\/eczema<\/span>that is to say current<\/span> corticosteroids emollients<\/span>, treatment of any secondary bacterial<\/span> infection<\/span> (Staphylococcus aureus), etc.<\/p>\n<\/span>What should I do to avoid formaldehyde allergy?<\/span><\/h2>\nIt is difficult to avoid all exposure to formaldehyde because it is normally present at low levels (usually <0.03 ppm) tanto en aire interior como exterior. Para la mayor\u00eda de las personas, la exposici\u00f3n a bajo nivel (hasta 0.1 ppm) no causa ning\u00fan problema. Los m\u00e9todos para evitar o minimizar la exposici\u00f3n se describen en la tabla a continuaci\u00f3n.<\/p>\n \n\n\nMethods to avoid or minimize exposure to high levels of formaldehyde<\/strong><\/td>\n<\/tr>\n\n\n\n- Wear clothing made of 100% cotton, silk, polyester, nylon, or acrylic; These fabrics generally contain less formaldehyde and are generally well tolerated by sensitive people\n
\n- Avoid all clothing made with fabrics that have been treated with formaldehyde (see above)<\/li>\n<\/ul>\n<\/li>\n
- In general, machine wash all new clothing and bedding in hot soapy water several times before use.<\/li>\n
- Buy furniture made from pressed wood products only if the surfaces and edges are laminated or coated<\/li>\n
- Occupational exposure can be reduced by identifying potential sources of exposure (material safety data sheets should be available to employees) and taking precautions to minimize exposure by wearing appropriate protective clothing.<\/li>\n
- To reduce the formaldehyde content in the air, increase ventilation by opening doors and windows and installing exhaust fans in closed areas<\/li>\n
- Read product labels and avoid not only formaldehyde itself, but also preservatives that release formaldehyde. Some of these are known by the following names:\n
\n- Quaternium-15<\/li>\n
- 2-bromo-2nitropropane-1,3-diol<\/li>\n
- imidazolidinyl urea<\/li>\n
- diazolidinyl urea<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
