Oil-free analysis is a statement that people who have oily skin should pay attention when buying cosmetic products. In particular, consumers who do not want a feeling of oiliness in the skin tend to buy such products.
Vegetable oils are the leading oils used in cosmetics. First of all, it is necessary to prove that these oils are not in the product by looking at vegetable oils. For this, it is necessary to examine the fatty acid composition or spectral analysis of the oils.
But for oil-free it just isn't enough. Because non-plant oils (silicone oil, mineral oil, etc.) are often used in cosmetic products and these products do not contain fatty acid. Therefore, in addition to vegetable oils, this type of non-vegetable oils should also be analyzed.
Oil-free analysis can be performed in Saniter laboratory.
