ACRYLATES: Allergen or Not An Allergen?

Allergen Acrylates Named 2012’s Contact Allergen of the Year by the American Contact Dermatitis Society, acrylates are interesting because, a little like clay and ceramics, they are strong irritants and allergens when wet (or in their powder or paste form) but tend to be fine when hardened. Polymerization is the process that causes acrylates to […]
PROPOLIS/BEESWAX: Allergen or Not An Allergen?

Not An Allergen … yet Basil There are some case studies of reactions to basil oil, and it is not currently listed in published lists of top common allergens. However, this heavenly herb is, along with mint and lavender, part of the Labiatae (Lamiaceae) family of top contact allergens. We therefore suggest to use it […]
STAINLESS STEEL WATER BOTTLE: Allergen or Not An Allergen?

Not An Allergen … maybe Stainless Steel Water Bottle Nickel has been the number one contact allergen for years, was the 2008 Allergen of the Year of the American Contact Dermatitis Society, and is everywhere.

COLORED TABLETS, PILLS, CAPSULES: Allergen or Not An Allergen?

Allergen Colored Tablets, Pills Capsules Many dyes and some colorants are on published lists of top contact allergens.
