UV protection hair care products in the current marketplace are mainly monomeric and adopted from skin care, therefore lacking substantivity and water solubility. This article reviews the detrimental effects of each range of UV light to hair and presents experimental results showing the sun protection performance of polyamide-2 for both hair morphology and artificial hair color fading.

Design considerations for broad-spectrum UV filters include photostability, solubility, efficacy, safety, registration, patent freedom, and PPD performance. These criteria are described and then applied in the case of bis-Ethylhexyloxyphenol methoxyphenyltriazine (BEMT), a new broadspectrum sunscreen active.

Most oral care products address plaque, caries, gingivitis, etc., with wellapproved active ingredients, however, consumers are increasingly looking for a more natural and complete approach to oral care. In this study, the catechin fraction of green tea – specifically epigallocatechin gallate (EGCG), exhibited several activities in oral care while offering a natural alternative.
