Background: Propylene glycol (PG) may cause allergic or irritant contact dermatitis. It primarily functions as a vehicle, solvent, or emulsifier in cosmetics and topical medications. Objectives: To characterize the prevalence of positive patch‐test reactions to PG and the epidemiology of affected patients. Methods: Retrospective analysis of cross‐sectional data compiled by the North American Contact Dermatitis Group (NACDG) from 1996 to 2006. Results: Of 23,359 patients, 810 (3.5%) had allergic… Expand
Patch Testing to Propylene Glycol: The Mayo Clinic Experience
TLDR
Propylene glycol is common in skin care products and is associated with both allergic and irritant patch test reactions, and increased concentrations were associated with increased reactions. Expand
Wound-Related Allergic/Irritant Contact Dermatitis
TLDR
Clinicians should be cognizant of the allergens in wound care products and the potential for sensitization, and manufacturers should be encouraged to remove common allergens from wound care Products. Expand
Common Allergens Identified Based on Patch Test Results in Patients with Suspected Contact Dermatitis of the Scalp
TLDR
Frequent sources of allergens for metals include hair clasps, pins, and brushes, while frequent sources of allergen for preservatives, fragrance mix, and balsam of Peru include shampoos, conditioners, and hair gels. Expand
Pediatric Contact Dermatitis Registry Inaugural Case Data
TLDR
This US database provides multidisciplinary information on pediatric ACD, rates of PPT, and relevant RPPT reactions, validating the high rates of pediatricACD previously reported in the literature. Expand
Intolerance to cosmetics as key to the diagnosis in a patient with allergic contact dermatitis caused by propylene glycol contained in a topical medication
TLDR
A 28-year-old woman had a 1-week history of herpes zoster on the chest, treated for the last 4 days with oral famciclovir and Zovirax® cream (GlaxoSmithkline, Madrid, Spain), and had a past history of intolerance to several cosmetic products that prevented her from using these. Expand
Wound-Related Allergic/Irritant Contact Dermatitis.

TLDR
Clinicians should be cognizant of the allergens in wounds care products and the potential for sensitization, and manufacturers should be encouraged to remove common allergens from wound care products, including topical creams, ointments, and dressings. Expand
Propylene Glycol in Contact Dermatitis: A Systematic Review
TLDR
This review serves to delve into what the authors know about PG from previous reports and studies so that providers will have a better understanding of PG contact dermatitis. Expand
Propylene glycol allergic contact dermatitis. A quick reference guide for propylene glycol-free topical corticosteroids in Saudi Arabia.
TLDR
Cutaneous reactions to PG are mostly irritant in nature, but true allergic sensitization does occur, and irritant reactions are generally more common, less vesicular, and tend to be associated more with burning sensation than pruritus as compared with allergic reactions. Expand
Men's Facial Moisturizers in the Metrosexual Era: Characteristics, Allergens, and Relevance of Men's Products in Modern Dermatology.
TLDR
Men's facial moisturizers commonly contain fragrances, emulsifiers, and glucosides but relatively few allergenic preservatives, which may reflect changes in modern PCP preservation and be important for modern dermatologists to be aware, especially in a new era of male skincare. Expand
Irritation and allergy patch test analysis of topical treatments commonly used in wound care: evaluation on normal and compromised skin.
TLDR
Patch test studies demonstrated that BTE showed the greatest irritancy potential in both normal and compromised skin whereas AHO showed the least. Expand

North American Contact Dermatitis Group Patch‐Test Results, 2003‐2004 Study Period
TLDR
Allergic contact dermatitis from nickel and budesonide may be increasing in North America, and the results again underscore the value of patch‐testing with many allergens. Expand
North American Contact Dermatitis Group Patch‐Test Results, 2001‐2002 Study Period
TLDR
The findings of patch testing from January 1, 2001, to December 31, 2002 reinforce the need for a more comprehensive group of diagnostic allergens than those found in the standard screening kits. Expand
Skin‐sensitizing and irritant properties of propylene glycol
TLDR
According to patch test data, PG seems to exhibit very low sensitization potential, and the risk for sensitization to PG on uncompromised skin seems to be very low. Expand
Propylene glycol dermatitis: re‐evaluation of an old problem
TLDR
Future studies on propylene glycol dermatitis should include repeated patch tests with serial dose dilutions, repeated open application tests/pro vocative use tests, oral challenge tests, and biopsies for a more complete evaluation of mechanisms and clinical significance. Expand
North American Contact Dermatitis Group patch test results for the detection of delayed-type hypersensitivity to topical allergens.
TLDR
The usefulness of patch testing is enhanced with the number of allergens tested, because allergens not found on the commercially available screening series in the United States frequently give relevant allergic reactions. Expand
North American Contact Dermatitis Group patch-test results, 1998 to 2000.
TLDR
The findings reinforce the need for a more comprehensive group of diagnostic allergens than is found in the T.R.E.U. TEST, which is sold in the United States. Expand
European Standard Series patch test results from a contact dermatitis clinic in Israel during the 7‐year period from 1998 to 2004
TLDR
This study is the first to provide data on the frequency of sensitization and important allergens in the aetiology of ACD in Israel and concludes that ESS is an appropriate screening system for the diagnosis of ACd in Israel. Expand

TLDR
Skin reactions due to propylene glycol are rare and should not bring the preparation into unnecessary discredit, but the possibility of propylene Glycol allergy should be recognized by dermatologists as propyleneglycol is used in local steroids and other topical preparations. Expand
Experimentally‐induced irritant contact dermatitis
TLDR
Responder rates lower than 75% had to be accepted for benzalkonium chloride and sodium hydroxide in order to prevent overly severe reactions, whilst propylene glycol proved to have only marginal irritant properties. Expand
Patch testing by additional series of allergens: results of further experiences.
TLDR
The cost of patch testing AS is not irrelevant, but it can be compensated by the advantages deriving from the increase of data concerning ACD etiology, and Cobalt chloride could be (re)introduced in the standard series. Expand
