Although sunscreens are widely used by an increasing number of people, they rarely cause adverse reactions such as allergic and photoallergic contact dermatitis. Benzophenone and octocrylene are the sun filters that most commonly cause allergic reactions, however other filters may sometimes play a role as sensitizers. We report a case of an allergic contact dermatitis to tinosorb M®, an organic compound with physical and chemical sun filter features. It contains methylene bis-benzotriazolyl-tetramethylbutylphenol (its active component), water, propylen glycol, xanthan gum and decyl glucoside. This latter is a surfactant that is added to stabilize the compound. Commonly well-tolerated, tinosorb M® has been recently described as sensitizer. It may cause allergic and photoallergic contact dermatitis caused by the filter itself or by decyl glucoside. Due to such sensitizing proprieties, and to the cross-reactivity of decyl glucoside with other glucosides present in several cosmetics, recently a new kind of tinosorb M glucosyde-free has been introduced to the market.

Abstract

Although sunscreens are widely used by an increasing number of people, they rarely cause adverse reactions such as allergic and photoallergic contact dermatitis. Benzophenone and octocrylene are the sun filters that most commonly cause allergic reactions, however other filters may sometimes play a role as sensitizers. We report a case of an allergic contact dermatitis to tinosorb M®, an organic compound with physical and chemical sun filter features. It contains methylene bis-benzotriazolyl-tetramethylbutylphenol (its active component), water, propylen glycol, xanthan gum and decyl glucoside. This latter is a surfactant that is added to stabilize the compound. Commonly well-tolerated, tinosorb M® has been recently described as sensitizer. It may cause allergic and photoallergic contact dermatitis caused by the filter itself or by decyl glucoside. Due to such sensitizing proprieties, and to the cross-reactivity of decyl glucoside with other glucosides present in several cosmetics, recently a new kind of tinosorb M glucosyde-free has been introduced to the market.
