What do StriVectin Neck Cream and wood sealant have in common?
The Cosmetic Database, put together by the Environmental Working Group, doesn't like disodium distyrylbiphenyl disulfonate one bit. It associates it with developmental/reproductive toxicity, organ system toxicity and irritation. Animal studies in the 1970s showed "sense organ effects" at low doses. However, I couldn't find anything more recent to corroborate this.
It turns up a lot in soaps and laundry detergent. Unilever describes it as an 'optical brightener', something that absorbs light to make it look whiter (optical brighteners have replaced 'blue' in washing powder to achieve that whiter-whites effect). It is also in Amatokin Eye Cream, which is made by the same group of companies as StriVectin.
