"Gaunyle" is advertised as "organic phenyle" and "organic phenyl" and as a general disinfectant for floors - thus i believe the idea is that is an 'organic' alternative to Phenol, which is phenyle+OH.
Anuradha Modi from the Holy Cow Foundation [...] said she was working
on a deal to get the company that supplies housekeeping items to
government offices to use the product — which is called "Gaunyle",
with gau the Hindi word for cow.
"We have tested the product in labs and we can say that it is much
better than the phenyl that you get in the market which is so full of
chemicals," she told AFP.
the HolyCow Foundation (HCF) spells it 'Gonyle' on a graphic, and 'Phenyle' on its shop. (Aside: The HCF uses Gau-X monikers for all kinds of products won from waste products of old cows ostensibly to finance the wellbeing of said old cows, for religious reasons) - The shop acknowledges that the pine and neem are not only for smell : "Based on the antimicrobial properties of Cow Urine, Neem, and Pine oil"
The ingredients of gaunyle are listed as "Gau Ark, Pine Oil, Neem Oil,permitted organic Emulsifier, RO Water", while a manual(p.347) says:
- l litre gaumutra
- 200 g neem leaves
- l litre pine oil
- 100 g emulsifier Procedure First, boil 1 litre of gaumutra with 200 g of neem leaves till it becomes 250 ml. This solution has to be kept
for 6 hours and turns into Neem kadha. Mix 100 ml of pine oil solution
and add 875 ml of distilled water is added. Next, put 25 ml of neem
kada in it and mix well after adding emulsifier
- Pine Oil is the higher boiling fraction of turpentine; It is a bactericide, fungicide and herbicide
- Neem Oil is far more toxic than pine oil, but also offers insect repellent qualities - note that the manual specifies leaves and lets them boil down instead of distilling them, resulting basically in neem broth
- organic emulsifiers (permitted?) can be many things, it is basically just a descriptor of being able to blend oil and water. Could be anything including highly toxic or completely benign.
- RO water probably just means 'reverse osmosis' water, i.e water pressed through a semi permeable membrane, thus free of solid matter and free of many dissolved molecules, though not all.
- the Gau Ark probably denotes Gaumutra Ark, i.e. distilled cow urine; A search on Google Scholar finds that it is anti-everything-bad (fungi, bacteria, diabetes, insects, snails ...) and pro-everything-good (plant growth, health, wound healing, ...), though there is a dearth of papers comparing this to any other urine, which keeps the knowledge gain manageable. - note that the manual takes cow urine and boils it down, instead of distilling, thereby retaining all mineral content which is inadvisable for a cleaning product.
Using cow-urine with neem oil and pine oil in a floor disinfectant seems like an idea, as long as you keep the bottle away from children and pregnant women, which is good advice for cleaning agents anyways.
The manual sees 250ml of boiled down cow urine (1l CU with 200g Neem leaves, which are probably extracted, then discarded, as there is no blending step), mixed with 1kg Pine oil and 100g emulsifier, so the resulting cleaning agent (meant to be diluted in water about 1:40) is mostly Pine Oil. Pine Oil is a recognized floor cleaning and disinfecting agent.
As the claim asserts that is is better than a "chemically bad" alternative, this seems to pan out (no indication that cow urine is "chemically bad/worse/worst", which would be the only way that claim could be busted).
The claim about Gaunyle being environmentally friendly ... It's a race between 'essential oils' vs 'essentially oil', essentially.
