Enhanced skin absorption

Expand content Collapse content
Concern Reference
Sulisobenzone increased penetration of 2,4D (a pesticide) by 48% and decreased lag time by 34% of controls.Pont AR, Charron AR, Brand RM 2004. Active ingredients in sunscreens act as topical penetration enhancers for the herbicide 2,4-dichlorophenoxyacetic acid. Toxicol Appl Pharmacol 195(3): 348-354.
Penetrated into skin. Less was recovered if the vehicle was an oil/water emulsion as opposed to an aqueous solution{Couteau, 2001}

Human skin toxicant or allergen - strong evidenceJACT 2(5):79-84, 1983 confirmed 09/02 IJT 24(S1):10-18, 2005
Human skin toxicant or allergen - strong evidenceEWG Assessment of Open Scientific Literature
Benzophenone 4 (sulisobenzone) produced significantly more photoallergic contact dermatitis patch test reactions than the other UV filters that were tested over a 3 year period, and was the third most frequently sensitizer overall.Hughes TM, Stone NM 2007. Benzophenone 4: an emerging allergen in cosmetics and toiletries? Contact Dermatitis 56(3): 153-156.
2 of 82 patients examined exhibited photoallergic contact dermatitis reactions to benzophenone-4.Rodriguez E, Valbuena MC, Rey M, Porras de Quintana L 2006. Causal agents of photoallergic contact dermatitis diagnosed in the national institute of dermatology of Colombia. Photodermatol Photoimmunol Photomed 22(4): 189-192.

ABOUT THE SKIN DEEP® RATINGS

EWG provides information on personal care product ingredients from the published scientific literature, to supplement incomplete data available from companies and the government. The ratings below indicate the relative level of concern posed by exposure to the ingredients in this product - not the product itself - compared to other product formulations. The ratings reflect potential health hazards but do not account for the level of exposure or individual susceptibility, factors which determine actual health risks, if any.
