Hello fans of GFSE and those who are involved in the production and distribution of GFSE.
This post has been written because of the latest comment to the article Ban Citricidal and Grapefruit Seed Extract:, the comment is copied at the end of this post.
Here is information to a pdf file on the toxicology of Benzethonium chloride from Material Safety Data Sheet Benzethonium Chloride MSDS from Science Lab.
“Section 11: Toxicological Information
Routes of entry: inhalation, ingestion
Toxicity to animals: Acute oral toxicity (LD50): 3.38 mg/kg [Mouse]
Chronic Effects on Humans: Causes damage to the following organs: mucous membranes
Other Toxic effect on Humans: Hazardous in case of skin contact (irritant). of ingestion. of inhalation.
Special Remarks on Toxicity to animals: Not available
Special Remarks on Chronic Effects on Humans: May affect genetic material (mutagenic). May cause cancer based on animal test data
Special Remarks on other Toxic Effects on Humans:
Acute Potential Health Effects:
Skin: Causes skin irritation. It may be absorbed by the skin.
Eyes: Causes eye irritation. Inhalation: May cause respiratory tract irritation. Ingestion: Harmful if swallowed. May cause gastrointestinal tract irritation with vomiting, and diarrhea.
May affect behaviour (CNS, depression, excitement, convulsions, seizures, coma). respiration (respiratory depression). blood. urinary system (hematuria). metabolism (weight loss).
Chronic Potential Health Effects: Prolonged or repeated ingestion or skin contact may affect metabolism, the endocrine system (thymus) and cardivascular system. Prolonged or repeated skin contact may cause dermatitis.”
Here is information to a pdf file by J. Agric. Food Chem 2001 Indentification of Benzethonium Chloride in Commercial Grapefruit Seed Extracts by Gary Takeoka, Lan Dao, Rosalind Y Wong, Robert Lundin and Noreen Mahoney (Western Regional Research Center, Agricultural Research Service, U.S. Department of Agriculture, 800 Buchanan Street, Albany, California 94710 ) on the content of Grapefruit Seed extract and I copy the conclusion drawn after extensive and specific laboratory tests.
“Commercial grapefruit seed extracts (GSE) were extracted with chloroform. The solvent was evaporated, and the resulting solid was subsequently analyzed by high-performance liquid chromatography, electrospray ionization mass spectrometry, nuclear magnetic resonance (NMR) spectroscopy, and elemental analysis (by proton-induced X-ray emission [PIXE] analysis). The main constituent was identified as benzethonium chloride, a synthetic antimicrobial agent commonly used in cosmetics and other topical applications. This compound comprised 8.03% (n ) 2) of the liquid GSE sample. Higher amounts of benzethonium chloride were found in powder GSE samples.”
I am not the only one who will not use or touch Citricidal or Grapefruit Seed extract. Some of the comments to the article Ban Citricidal and Grapefruit Seed extract may be trying to discredit me and my blog, but the information about the toxicity of Citricidal and Grapefruit Seed extract is there for all to see.
Here is the latest comment left by a reader of the article Ban citricidal and grapefruit seed extract (18th July 2012):
“I am happy to say that I have received a very thorough response from the producers of Unifect-GSE™ who have assured me that they have fully inspected the manufacturers processing and have also provided me with articles. I am confident that in this instance you are wrong. For anyone else reading this I would suggest that you complete further research before believing this blog.
All the best.”
Reader, I suggest you send me copies of those articles and the names of those who have written them and their science, because the evidence from independent testings is irrefutable. You have made me wonder if you are involved in the production and distribution of GFSE hence your two recent Good Cop, Bad Cop comments.
Unifect.GSE is a trade mark, here are their companies:
Unifect who offer effective ingredients (their words not mine) and their partner site:
Natural Actives Which is about, apparently, Natural Actives and the person who started it: “Natural Actives is a magazine style site – a showcase for naturally effective ingredients from around the world.”
