title: Sunscreen ingredients and labelling: a survey of products available in the UK.
abstract: BACKGROUND
  In Europe, where sunscreens are classified as cosmetics, products may contain one or several of 27 permitted 'ultraviolet filters'. We were unable to find published data on the frequency of usage of individual ultraviolet (UV)-absorbing chemicals in currently available sunscreens.
  
  
  OBJECTIVE
  To record the active ingredients and labelling characteristics of sunscreens available in the UK.
  
  
  METHODS
  In 2005, two dermatologists visited seven retail outlets, which stocked a large range of sunscreens. Manufacturers were also contacted. For each product, the names of UV-protective ingredients and the labelling information, including sun protection factor (SPF), UVA protection and age group for which the product was marketed were recorded.
  
  
  RESULTS
  Data on 308 skin sunscreen products and 21 lip sunscreens were recorded. For skin products, the SPF ranged from 2 to 60. In total, 23 different UV-absorbing ingredients were found, 4 of which were found in > 25% of products. The child and baby skin sunscreens (n = 52) had a significantly higher median SPF of 40, compared with 15 for the remaining 256 adult products (P < 0.001). The number of UV-absorbing chemicals and the frequency of those commonly used did not differ substantially between child and adult products. Of skin sunscreens marketed for babies, 60% contained 2-6 UV-absorbing chemicals. Nearly half of the skin sunscreens contained at least one of nine UV-absorbing chemicals not available in patch testing formulations from commercial suppliers.
  
  
  CONCLUSIONS
  The results of this survey indicate current sunscreen content and labelling, and are a benchmark from which new developments can be tracked. More standard sunscreen labelling, particularly separate listing of active ingredients, would be helpful. It was surprising to find UV-absorbing chemicals in products sold for use on babies.
