3.1. Utrzymanie prawidłowego stanu skóry (ID 2748)
Five references were cited to substantiate the claimed effect. The first reference is related to an observational study investigating the effect of different nutrients on skin ageing. Amongst other the effect of linoleic acid was studied, but no direct reference was made to an effect of Carthamus tinctorius L.. Two references were animal studies, one rat study examined the effect of essential fatty acids on maintaining the epidermal water permeability barrier and the other investigated the effect of adding zinc and/or linoleic acid to a complete and balanced diet on the skin and haircoat condition of adult dogs. The forth reference was a review on essential fatty acids and the skin and the fifth reference was a periodical on skin care.
Even though safflower oil contains linoleic acid, the references provided do not address the relationship between the consumption of safflower oil from seeds of Carthamus tinctorius L. under the proposed conditions of use.
The Panel notes that the references cited did not provide any scientific data that could be used to substantiate the claimed effect. The Panel concludes that a cause and effect relationship has not been established between the consumption of Carthamus tinctorius L. and maintenance of normal skin.
