(STUDY) Dry shampoos contaminated with benzene, a known carcinogen

The following is an excerpt from MedPage Today.

Dry shampoo has joined the growing list of cosmetic and hygiene products that contain benzene, a known human carcinogen, according to an analysis from the independent laboratory Valisure.

Of 148 batches of dry shampoo spray from 34 different companies, 70% contained quantifiable levels of benzene.

Some products contained up to 170 times the FDA-imposed benzene limit of 2 parts per million (ppm), Valisure found.

For example, Not Your Mother’s dry shampoo had a benzene concentration of up to 340 ppm. Other brands whose products contained benzene levels above the FDA limit included Paul Mitchell, Sun Bum, Batiste, Sebastian, and Redken, among others.

Valisure filed a citizen petition with the FDA Monday, requesting a recall of contaminated dry shampoo products. They also asked the agency to redefine and clarify benzene limits in cosmetics and other regulated products, noting that their findings represent the highest and most broadly detected levels of benzene that it has found in a consumer product to date.

“The detection of high levels of benzene in dry shampoos should be cause for significant concern since these products are likely used indoors, where benzene may linger and be inhaled for prolonged periods of time,” David Light, CEO of Valisure, said in a press release.

Benzene, which is used primarily as a solvent in chemical and pharmaceutical industries, is known to cause leukemia or other blood disorders in humans. Trace levels of the carcinogen can be found in cigarette smoke, gasoline, glues, adhesives, cleaning products, and paint strippers. It is also a contaminant in the petroleum industry, the press release noted.

Valisure has previously detected unlawful levels of benzene in hand sanitizerssunscreens, and spray deodorants.

The high presence of the cancer-causing agent in these hygiene and cosmetic products is evidence that further industry and regulatory action is needed, Light said.

The FDA has alerted drug manufacturers to benzene contamination in recent months, clarifying that they should appropriately test their products for levels above 2 ppm.

  1. This Article and the effects on Benzene and Cell’s ? And past research gave me a Ureaka physics and engineering idea on a New kind of Medical device scanner.. Right out of a science fiction movie that can be made real life ? You big tech companies involved in users Data collection hiding in back of my devices like Microsoft team live in Windows 11 and Hp-Hewlit packard laptop, Don’t Tell em what’s on my computer. in Data Laundering ? Some people in life likr to figure out crossword puzzles others like me like to figure out the real un-explained in life ! From the inner mind to the outer limits …

  2. Free info to help farmers in better New chemical’s for pesticide’s feedback your welcome to use ? United Farmers need all the help they can get in cutting costs in inflation for You and I in producing better food and crop’s as well as Better alternatives in helping the farm ground so keeping this in Mind for us all your welcome to this idea in physics and engineering from the Hoosier State ? Instead of using Pfas pesticides, use more safer Natural oils to do the same job. ‘What you want to do is use a New Heated pressure sprayer to convert natural liquid oil’s into spray Gas Fog Molecules to spray crops. This Converts oil’s into a Better safer Fog gas treatment molecules to crops. All Natural and better for Farm grounds here in America bringing a much better alternative of the ways of the past ? And oil liquids in the conversion’s Fog molecules processes last longer… New U.S. Farm report better idea’s into the 22 century Lean Manufacturing Smarty pant’s dance ? “Ha ! ha! ha!
