Regardless of the actual percentages, it is quite clear that a lot of what we apply on our skin ends up in our bodies. So it makes good sense for us to pay attention to the ingredients that are in our skin care products. Choosing natural and organic ingredients immediately cuts out a lot of preservatives, synthetic fragrances and color compounds that are suspect to be harmful to us. You can be assured that with a certified natural or organic product, extra effort has been taken in the interest of health and cost-saving short cuts avoided.
Synthetic color or FD&C colors are mostly derived from coal tar. Many have been banned from food by the FDA for various reasons: carcinogenicity, allergy inducing, general toxicity, etc - A number caused illnesses in children. A few of these colors have now been banned from cosmetic use. For instance, the FDA has already banned the new use of Red No.3, a carcinogen that may interfere with nerve transmission in the brain and cause genetic damage.
Synthetic colors, if listed on a product, will appear as FD&C or D&C followed by a number, ie. FD&C Red No. 6. Given the various health risks associated with many synthetic colors, if a personal care product uses it, it's suggested that you don't use it.
Tsi-La Organics use only 100% natural and organic colors and are completely free of FD&C colors.
