7 Ingredients to Ban From Your Bathroom

  • 2 of 3

Sodium Lauryl/Laureth Sulfate (SLS) is a synthetic detergent and foaming agent connected to skin and eye irritation. It’s also linked to the byproduct 1-4 dioxane, a suspected carcinogenic contaminant produced by the ethoxylation process, used to make some ingredients less harsh. (Sodium lauryl sulfate is converted to sodium laureth sulfate, for example.) Ethoxylation is one reason why so many “gentler” products — those with a natural slant or made especially for kids — have turned up surprisingly high levels of toxins.

According to researchers at the Organic Consumers Association, who conducted tests for 1-4 dioxane on hundreds of products from 16 major brands in 2008, only 23 products were found to be free of 1-4 dioxane contamination. Many companies have quit using ethoxylated ingredients like sodium lauryl sulfate to avoid 1-4 dioxane contamination as well as allergic reactions, and the standard for the Whole Foods Premium Body Care Seal doesn’t allow it. Look for “-eth” at the end of other ingredient names to detect this process.

Synthetic fragrances can contain as many as 200 ingredients that manufacturers are not required to disclose. A common allergen, “fragrance” on an ingredient label is a reliable indicator that the product contains phthalates, unless it’s clearly indicated that the fragrance contains no synthetics. Higher-potency fragrances are the likeliest suspects for high concentrations of phthalates. Sophie Uliano, natural-beauty expert and author of Gorgeously Green: 8 Simple Steps to an Earth-Friendly Life (HarperCollins, 2008), points out that “fragrance-free” or “unscented” products aren’t always a dependable alternative, since manufacturers sometimes use masking fragrances in place of identifiable scents. Look for products that explicitly say “no synthetic fragrances” or “natural essential oil fragrance only,” or try to buy from companies that have signed the Compact for Safe Cosmetics.

Diethanolamine (DEA) and Triethanolamine (TEA) are emulsifiers and foaming agents typically found in shampoo and body wash. They can produce allergic reaction as well as, ironically enough, hair and skin dryness. They belong to the category of “nitrosamines” that Uliano cautions against, which studies have shown can be carcinogenic.

Diazolidinyl and Imidazolidinyl Urea are frequently used synthetic preservatives that can cause contact dermatitis and are suspected formaldehyde releasers. They appear in sunscreen, lotion, shampoo — the same places you’ll find parabens.

60% of what you put on your skin is absorbed into it, so be careful what you put on it.
