that cosmetic preservatives are highly controversial? Many products use preservatives that inhibit bacterial growth and therefore prevent infection and intern extend product shelf life. However, there are numerous reports and studies showing products with these powerful preservatives can be extremely harmful and toxic to the body. Some common preservatives in cosmetic products are:
Parabens (Propyl, Methyl, Butyl or Ethyl)
This preservative is commonly used in cosmetics because they are inexpensive and relatively effective. Their use in cosmetics is particularly troubling because of their absorption into the blood stream bypasses the gastrointestinal tract where they might be broken down. Preliminary studies show these parabens mimic female estrogen which is know to cause breast cancer in women and testicular cancer in young boys.
Imidazolidinyl and Diazolidinyl Urea
These are the most commonly used preservatives after the parabens. They are an established cause of contact dermatitis (American Academy of Dermatology) and release formaldehyde, which is toxic.
Alcohol, Isopropyl (SD-40)
This is very drying and irritating solvent and dehydrator that strips your skin’s natural mantle, making us more vulnerable to bacteria, moulds and viruses. It is made from propylene, a petroleum derivative. It may promote brown spots and premature aging of skin.
Sodium Lauryl Sulfate (SLS)
This harsh caustic detergent is used because it is cheap and sudses well. It is used as an engine degreaser and garage floor cleaner but you will also find it in shampoo, soap, facial cleaners etc. Studies have indicated that SLS enters and maintains residual levels in the heart, liver, lungs and brain from basic skin contact. This is potentially dangerous since SLS is a mutagen, capable of changing the information in the genetic material of your cell and organs. SLS can corrode hair follicles and inhibit hair growth, contributing to hair loss. (High levels of skin penetration may occur at even low use concentration).
Triethanolamine (TEA)
This is often used in the base of a product and to adjust the pH. TEA causes allergic reactions including eye problems, dryness of the hair and skin and can be toxic if absorbed into the body over time.
Propylene Glycol
This is a cheap synthetic petrochemical used as an emulsifying base in creams and lotions to make the skin look smooth but ultimately it ages the skin faster. The Material Safety Data Sheet tells you to avoid skin contact because it is a skin irritant! It can denature the skin’s protein leading to poor, saggy skin. It can be absorbed through your skin and potentially cause allergic reactions and liver and kidney damage.
Mineral Oil
This cheap petroleum-based oil clogs the skin’s pores and enlarges them leading to poor saggy skin. It decreases the ability of the skin cells to exchange nutrients and waste products. Those allergic to petroleum products may develop skin irritations.
Synthetic Colors
Synthetic colors are used in skin cream and shampoos to make them colorful. Avoid them at all costs along with hair dyes (with the exception of some henna products). They can cause allergies, skin and nerve problems. Synthetic colors are labeled as FD&C or D&C followed by a number and color. |
