76 mg/d (13 mg/kg/d for a person weighing 70 kg) with the majority (50 mg/d) derived from cosmetics and personal hygiene product exposure Notably, food preparations (eg, mayonnaise, jams, salad dressings, etc) are thought to account only for approximately 1 mg/d33 The parabens, when absorbed through the skin, are partially metabolized by carboxyl esterases in the skin, liver, and kidney34 Recently, it has been demonstrated that a portion of parabens may be retained in human body tissues without hydrolysis by tissue esterases, which has raised concern over the potential for adverse side effects35 Special regard has been given to the estrogen-like effects, which were first described by Routledge et al in 1998 and have been further substantiated by several studies36 39 Since estrogen is a major etiologic factor in the development of human breast tissue and breast cancers, Darbre et al proposed that parabens and other chemicals that are used in underarm cosmetics may have contributed to what was then, in 2003, the increasing incidence of breast cancer40 In an uncontrolled study of 20 patients with breast tumors, parabens were found in 90% of the

Parabens
The para-hydroxybenzoic acids (parabens) are a family of five alkyl esters that differ in para-position chemical composition substitutions on the benzene ring (methyl paraben, ethyl paraben, propyl paraben, butyl paraben, and benzyl paraben) These chemical substitutions impart on each paraben ester a different solubility and antimicrobial activity spectrum Frequently, manufacturers take advantage of this and use the parabens in conjunction with each other to enhance antimicrobial efficacy33 In the United States, the average total paraben exposure per individual is estimated to be approximately

tissues suggests the need for prospective longitudinal studies37 With regard to topical adverse effects from cosmetic preparations, the parabens have caused both irritant and allergic type contact dermatitis45 48 For example, paraben allergy has been described in association with facial cosmetics, ultrasound gels, topical steroid creams, and food additives49 52 A recent meta-analysis by Krob et al revealed that despite widespread use of this preservative class, the overall prevalence and relevance of paraben allergy was remarkably low (05%), when compared to other preservative chemicals53 IODOPROPYNYL BUTYL CARBAMATE In 1996, iodopropynyl butyl carbamate (IPBC) was approved for use in the United States by the Cosmetic Ingredient Review at an allowable level of up to 01% in topical formulations3 Testing for this allergen began in Denmark in 1996 and in the United States in 1998, with current data suggesting that the sensitization potential is relatively low when compared to the other preservative allergens54 (See 37 for further discussion of preservatives) OTHER ALLERGENS IN SKIN, HAIR, AND NAIL CARE PRODUCTS (TABLES 18-5 TO 18-8) Skin reactions have been described with hair care products as well as hair
