Bioken® does not use harsh chemical agents like sulfates that cause skin irritation or damage hair, skin or other cells. Instead, only luxurious and extra gentle cleaners are used. These natural cleansers are derived from coconut and palm oils and are delicate enough not to strip the hair and scalp of essential oils. 

In addition to the absence of sulfates or synthetic fragrances or dyes, all Bioken® products are free of harmful chemicals that may increase the risk of cancer such as paraben and DEA. Bioken® also does not use sodium or alcohol in any product, as they can tend to cause hair to dry out.  All Bioken® products are also 100% vegan and are not tested on animals. 

With a perfected blend of botanicals and their delightful aroma, Bioken® brings a luxurious and sensual quality to every hair care experience. The result is healthy, youthful, silky hair with incredible shine.

BIOKEN® DOES NOT USE Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES)

These are very cheap surfactants, detergents, and emulsifiers that produce a lot of foam. In the cleaning industry, the same ingredient is used in garage floor cleaners, engine degreasers, and car wash soaps because of its corrosion ability. The molecular size of this chemical is small, causing it to be absorbed easily through the skin pores. It is also used in clinical testing as a skin irritant, to test the effectiveness of healing agents. The reason why we do not feel the irritation on our scalp or body is because it is diluted with water while in use, and usually quickly washed away. In bubble baths, this ingredient is classified as a drug because it eats away skin protection and causes rashes and infection to occur. Research studies on these ingredients have shown links to: hair follicle damage, skin damage, irritation of the skin and eyes, organ toxicity, developmental/reproductive toxicity, and endocrine disruption. 

A report published by the Danish Institute of Public Health, a single 24 hour exposure of SLS to human skin damages skin protein and causes prolonged disruption of “the skin barrier integrity of the skin,” to allow the penetration of carcinogens such as nickel and chromate. Thus, skin absorption of the multiple carcinogenic ingredients commonly found in mainstream industry cosmetics and toiletry products, including shampoos, could be greatly increased by SLS type detergents.  

Bioken® products are made with Sodium Lauryl Sulfoacetate

It is known to be gentle and safe to the skin. It is a natural ingredient which is plant derived from coconut and palm oils. It effectively removes surface oil, dirt, and bacteria while still being delicate on your scalp or skin. The molecular size for Sodium Lauryl Sulfoacetate is larger than the size of your pores, thus it will not penetrate the skin. As it is mild, the natural essential oils are not dried out from your scalp or skin. Another added benefit of this ingredient is that it is considered hydrophilic, meaning “attracted to water”. This allows it to be easily dissolved in water without leaving any residue. In addition, Sodium Lauryl Sulfoacetate is environmentally friendly as it is bio-degradable, being able to naturally break down. 

BIOKEN® DOES NOT USE Diethanolamine (DEA)

DEA is widely used in cosmetic products as an emulsifier, foaming and thickening agent. According to a 1995 study funded by the National Institute of Environmental Health Sciences, DEA has low acute toxicity but significant cumulative toxicity. This is because it cannot be easily excreted from the body, but instead it builds up in the fatty tissues of the liver, brain, kidneys, and spleen with repeated oral and skin exposure. Dr. Samuel Epstein, M.D., Professor of Environmental Science at the University of Illinois School of Public Health, states that “DEA is readily absorbed through the skin and accumulates in organs, such as the brain, where it induces chronic toxic effect.” 

The presence of DEA in products while sitting on the shelf can react with other ingredients to form Nitrosamines which are a known powerful carcinogen. Nitrosodiethanolamine NDEA then lingers, and builds up in fatty tissue liver, brain, kidneys, and spleen causing tissue and nerve damage. Since 1976, workers exposed to NDEA in metal working fluids, at levels similar to those in cosmetics, have been warned of cancer risks and steps taken to protect them. In 1979, the Federal Drug Administration (FDA) ordered the cosmetics industry to eliminate NDEA in their products, but 12 years later in 1991; the FDA tested 29 random cosmetic products and found that 27 out of the 29 were contaminated with NDEA. The FDA has no authority to require cosmetics be tested for safety before they are sold. 

The European governments and industries started to phase out the use of DEA since the 1980’s, but in the US, there are no rules and regulations on the use of DEA, therefore, numerous companies continue to use this harmful ingredient. Ingredients containing DEA, MEA, TEA are of the same category.


Paraben is a low cost preservative chemical used in cosmetic products. It protects against micro-organisms for a long period of time and keeps bacteria from growing. There are numerous types of Parabens, but methyl, propyl, and butylparaben are the most common found in beauty products. Parabens have been known to interfere with the functioning of the endocrine system (a system of glands, each of which secretes a type of hormone directly into the bloodstream to regulate the body), cause premature aging, and mimicking estrogen (may increase the speed of breast cancer development) by accumulating in the fatty tissues of the liver and kidneys. 

The US Environmental Protection Agency (EPA) in their report “Pharmaceuticals and Personal Care Products in the Environment: Agents of Subtle Change?” reported that “the chemical preservatives called parabens – methyl, propyl, butyl, and ethyl displayed estrogenic activity in several tests.” The chemicals in your body mimic that of your own hormones and can disrupt your endocrine system such as hypothalamus, ovaries, thyroid and more by getting absorbed through your skin or by getting into our drinking water. The EPA also stated that “continual introduction of these parabens into sewage treatment systems and directly to recreational waters from the skin leads to the question of risk to aquatic organisms.” In fact, scientists in Europe found endocrine-disrupting body care chemicals in the bodies of fish that humans are eating, and in human breast milk. 

“It is a known medical fact that estrogen stimulates breast cancer” and that “anything absorbed through the skin may be as high as 10 times the concentration of an oral dose. Think about how Nicotine and Birth Control hormone patches work – the chemicals are absorbed through the skin.” Dr. Elizabeth Smith, M.D. 

Researchers from the Kyoto Prefectural University of Medicine in Japan found that the methyl type of parabens increased UVB-mediated DNA, thus causing premature aging because the skin cells die at a more rapid rate than normal. 

Parabens may speed up the development of certain breast cancers. It acts like estrogen in your body, which may increase the risk of women developing estrogen-positive breast cancer. According to English researchers, they tested 20 breast cancer tumor samples and 18 out of 20 showed high concentrations of Parabens. The European Journal of Cancer Prevention reported that “Frequency and earlier onset of antiperspirant/deodorant usage with underarm shaving were associated with an earlier age of breast cancer diagnosis.” The parabens, along with other chemicals in the product may be to blame for this. 

A study published last year (2010) by researchers from the Centers for Disease Control found methylparaben in 99% of the urine samples tested, and informed that adolescent and adult woman showed significantly higher levels of methylparaben and propylparaben than other groups. The researchers stated the differences “probably reflect the use of personal care products containing these compounds.” In 2010, Denmark announced that it would draft legislation to ban butylparaben and propylparaben from products intended for use on children age 3 and younger. 

Bioken® uses an alternative preservative in the safest and mildest form

Methylchloroisothiazolinone is a preservative with antibacterial and antifungal properties. The Internatinoal Agency for Research on Cancer (IARC) does not list this ingredient as a known, probable, or possible human carcinogen. Another preservative Bioken® uses is Methylisothiazolinone, which is approved by the Cosmetic, Toiletry, and Fragrance Association (CFTA), US Environmental Protection Agency (EPA) by Japan, and by the European Commission for use in cosmetics.
