Petroleum (Petrolatum)

Derived from petroleum. Can be found in personal care products as a moisturizing agent. Possible carcinogen due to polycyclic aromatic hydrocarbons (PAHs) contamination.


Ingredient derived from benzene and propylene. It can affect the nervous system, lungs, and kidneys.


Used as a preservative in cosmetic products and also as a stabilizer in perfumes and soaps. Linked to allergic reactions and affected nervous system function in infants. May contain ethylene oxide residue which is a known carcinogen.

Safflower Oil

Highly processed industrial oil made from the seeds of a safflower plant. High in omega 6 fatty acids, which can be inflammatory.


Silicone-based compounds that are generally used for their softening, smoothing, and moistening action. Associated with reproductive issues, endocrine distruption, and cancer.

Sodium Benzoate

Preservative used in processed foods and beverages to extend shelf life. May form benzene when combines with certain additives. May increase risk of inflammation, oxidative stress, obesity, ADHD, and allergies.

May also be used in non-edible products where it is not considered toxic unless individual has specific skin sensitivity to sodium benzoate.

Sodium Lauryl Sulfate (SLS)

A surfactant used to help create foam in products. Can cause skin and lung irritation. Can be contaminated with 1,4 Dioxane, a known carcinogen.

Sodium Nitrite

Used as a preservative in processed meats. Linked to cancer risk.

Soybean Oil

Industrial seed oil and GMO crop made from soybeans. Can increase cholesterol levels and contains a high amount of both polyunsaturated fats (PUFAs) and omega-6 fatty acids.

Sunflower Oil

Industrial seed oil made from sunflower seeds. Highly refined and processed. Very high in Omega-6 linoleic acid.

*High Oleic Sunflower Oil is radically different from sunflower oil having at least 80% Oleic acid versus Linoleic acid.


Preservative used to maintain food color, shelf-life and prevent the growth of fungi or bacteria. Can cause sensitivites, headaches, dermatitis, and asthmatic reactions.

Synthetic Dyes

An umbrella term to describe synthetic color additives used as a dye. Includes Red 40, Blue 1, Green 3, Blue 2, Red 3, and Yellow 6. Derived from petroleum or crude oil. Have been linked to many health conditions from hyperactivity to allergic reactions to cancer.

Nail polish is an exception with synthetic dyes and it is recommended to limit use when possible.



A naturally occurring mineral substance used in a variety of cosmetic and personal care products from baby powders to eye shadows. Can be contaminated with asbestos and asbestos fibers, a mineral substance linked to cancer. May cause severe respiratory distress and adversely affect the female reproductive system.


Additive and preservative that may increase the risk for tumors and may be a neurotoxin.

Tetreasodium EDTA

Helps to keep a products texture, color, and odor consistent. It is made from formaldehyde and may be an eye irritant.

Titanium Dioxide

Whitening agent used in products. May be a carcinogen and can disrupt the gut.


Toxic chemical used in in nail products and hair dyes. Exposure can result headaches, dizziness, cracked skin, reproductive damage and respiratory complications.

Trans Fats

Artificial fats associated with heart disease and inflammation.


An antimicrobial agent commonly used in many soaps and detergents. There is evidence that triclosan is an endocrine disruptor and impacts thyroid function and thyroid homeostasis. Can accumulate in fatty tissues.

Triethanolamine (TEA)

Functions as a surfactant or pH adjuster in cosmetics and personal care products. Can form nitrosamines which are carcinogenic. Known to be toxic to the skin, the immune system, and the respiratory tract.




A common synthetic artificial flavoring with potential health concerns.

Vegetable Oil

Usually a mixture of oils. Highly processed and refined and high in Omega-6. Linked to inflammation and heart disease.
