Avoid These Potentially Harmful Ingredients: Artificial Colorants




While waiting for the completion of the remaking of my website, http://naturalhomemadesoap.net, where I will be sharing healthy natural products for your skin, hair and home, I decided to write a series of articles discussing what ingredients you may want to avoid when shopping for soap and cosmetics.  According to EWG.org, “companies are free to use almost any ingredient they choose in personal care products, with no proof of safety required.”  Safety testing is voluntary and controlled by the manufacturer of the products.  Personal care and household cleaning products expose the consumer to many chemicals that pose significant health risks through skin absorption, inhalation and ingestion.  Today my focus is on the potential harm of artificial colorants, whether in your food or on your skin.

What are artificial colorants?

Artificial colorants include both dyes and lakes and may be derived from petroleum, acetone or coal tar.  Dyes will dissolve in water but not in oil; whereas, lakes dissolve in oil but not in water and are often used in lipsticks, soaps and shampoos.  Petroleum is derived from petrochemicals and coal tar.  Coal tar is a by-product of the distillation of bituminous coal.  Petroleum clogs the pores, preventing the skin from being able to breathe and increasing the risk of acne break out; and coal tar is a known carcinogenic in large quantities.  Only 50% of the components of coal tar have been identified.  Some of its by-products are benzene, creosote, kerosine, naphtha, paraffin, and tuluene.  According to Leila McGehee Tucker, NC, CNC, "It takes up to 25 synthetic chemicals to create one artificial dye.  If a product is purple, it could potentially have 50 or more chemicals just in the color.” 1   To make matters worse, synthetic dyes become contaminated during the manufacturing process with other impurities like lead, arsenic or other heavy metals that are known to be carcinogenic or toxic to the nervous system.

Why are artificial colorants used?

If artificial colorants are known to be harmful, why do manufacturers use them in producing personal care products and cosmetics.  Synthetic dyes are less expensive than natural colorants.  Artificial colors tend to be more vibrant and uniform than colors made from natural sources.

Known affects of certain artificial colorants in food? 2, 3

BLUE 1, or Brilliant Blue FCF, is commonly used in beverages, candy and baked goods.  It has been shown to pose a small cancer risk.  It might affect neurons and occasionally causes allergic reactions.

BLUE 2 is commonly used in pet food, beverages, and candy.  Animal studies have shown inconclusive evidence of Blue 2 causing cancer in male rats.

GREEN 3, or Fast Green FCF, is used in candy, beverages, tinned green peas and other vegetables, sauces, and jellies.  Green 3 has been shown to possibly cause bladder and testes tumors in male rats.  It is poorly absorbed in the intestines.

RED 3 had been used in candy, maraschino cherries and baked goods until it was banned in 1983.  It causes sensitivity to light and learning difficulties.  It can increase thyroid hormone levels and lead to hyperthyroidism.  It was shown to cause thyroid cancer in rats and has since been replaced with Red 40.

RED 40 is used in soda pop, candy, gelatin desserts, pastries, pet food, and sausage.  This is the most widely used food dye.  Red 40 can cause allergy-like reactions and may cause hyperactivity in children.  It is mostly found in junk foods.

YELLOW 5, the second-most-widely used coloring, is used in gelatin dessert, candy, pet food, and baked goods.  It can cause allergic reactions, particularly in people who are sensitive to aspirin, and triggers hyperactivity in some children.  It may be contaminated with such cancer-causing substances as benzidine and 4-aminobiphenyl (or chemicals that the body converts to those substances).

YELLOW 6, or Sunset Yellow FCF, is used in beverages, candy, and baked goods.  This is the third-most-widely used dye.  Animal tests indicate that it causes tumors of the adrenal gland and kidney.  It may be contaminated with small amounts of several known carcinogens, such as 4-aminobiphenyl and benzidine (or chemicals that the body converts to those substances).  Yellow 6 may also cause occasional, but sometimes severe, allergic reactions.

Are the artificial colorants in personal care products harmful?

The ingredients in lotions and masks, which are left on the skin, can be absorbed into the body and have the potential to cause more harm.  While most manufacturers of the mass-produced personal care products believe that the artificial colorants in their products are used in such small amounts that they pose no threat, they are not taking into consideration that the average person uses several personal care products everyday.  Not enough studies have been done to provide conclusive evidence of the cumulative effects of long-term daily topical use of synthetic colors.

How do I know if a product has artificial colors in it?

Check the list of ingredients on the label.  Look for words like “colorant,” “blue lake,” or any of the “lakes,” a color followed by a number, “D&C,” or “FD&C.”

How can I avoid artificial colors?

·      Read the label.  Do not buy the product if it lists in its ingredients any of the above dyes, or uses such words as “colorant,” “lakes,” a color name followed by a number, “D&C,” or “FD&C.”
·      Shop for natural and organic products with ingredients you can pronounce.
·      Look for products without added color.
·      Look for products colored with natural dyes made from plants and herbs, such as turmeric or blueberries, and clays.
