pure soap
Hi I have been reading about making insectisides using pure soap. What is
pure soap sold as, i.e. trade name? Or will Dove soap do? Thanks Ron |

pure soap
Ron, all you need to do is collect any remnants of old toilet soap tablets
from the bathroom, put them in a large pot or jam jar, add hot water, stir and wait until the soap has turned gloopy. Dilute with more hot water and use the resulting liquid as a spray. Dove soap would be fine as would any other toilet soap. This soap spray works a treat with zapping whitefly. They don't like it on them!

Ysgrifennodd "ron" mewn neges r.co.uk... Hi I have been reading about making insectisides using pure soap. What is pure soap sold as, i.e. trade name? Or will Dove soap do? Thanks Ron Pure soap flakes are available from Tesco's under the name Granny's Original. I can't get them anywhere else. I use em to wash my waterproofs in, works a treat and is a lot cheaper than the expensive stuff you buy in outdoor shops (which is almost identical, only liquid in form and many times more expensive.)

T Dave R Most washing up liquid - including supermarket budget brands - is around 95% soap. There is nothing magical about soap which is merely a compound of glycerine, and fatty acids derived from sources such as tallow, grease, fish oils, and vegetable oils. All unscented washing up liquids are equally effective when used as shampoo*, bubble bath, insecticide, bicycle cleaner, engine degreaser, and hand cleaner, as are branded products often costing ten times as much, if not more. * In the late 60's/early 70's, civilisation as we know it was almost rocked to its foundations by Jilly Cooper's admission in the Sunday Times that she only ever washed her hair in Teepol - ICI liquid soap. Cue - "and it shows". michael adams ... |

Its active ingredient is sodium laureth sulphate, which is very different from sodium stearate and similar true soaps. I have no idea what the chemical distinction between a detergent and a soap is, but sodium stearate is pretty simple (C18H35NaO2 according to Wikipedia). For comparison, sodium laureth sulphate is CH3(CH2)10CH2(OCH2CH2)nOSO3Na, and the presence of both sulphur and nitrogen in the same organic molecule is a well-known warning flag. That is why sodium laureth sulphate is (a) more effective, (b) riskier for delcate fabrics and finished and (c) more likely to provoke reactions than sodium stearate. Regards, Nick Maclaren. |

Must admit that's a bit better than Mike's comments-but only just. Some of the cheaper washing up and Laundry liquids have an increasing amount of sodium fatty acids in them. It's one way of getting rid of the fat no one wants to eat anymore. What's this thing about nitrogen and sulphur being a well know warning flag? Come to think of it where is the Nitrogen in Sodium lauryl sulphate? It does not contain any does it? Perhaps dissolved Nitrogen in the tap water:-) |

And the reason has nothing to do with surplus fat that people don't want to eat. | What's this thing about nitrogen and sulphur being a well know warning flag? Check it out - it is. The point is that sulphur-containing proteins are often/usually very bioactive, and a hydrocarbon that contains nitrogen is very like a protein. | Come to think of it where is the Nitrogen in Sodium lauryl sulphate?

It's one way of getting rid of the fat no one wants to eat anymore. You use fat to dissolve fat; soap has been made from lard for millenia; you mix it with caustic soda and that makes it very hydrophobic at one end which dissolves fat very well and hydrophilic at the other (the sodium end) where it will dissolve in water., You end up with somethng that dissolves the grease but will wash away.

Fair enough, I'll settle for that. quote Sodium lauryl sulphate (SLS) is an anionic surfactant (detergent) which is included as a foaming agent (to clean and make bubbles) in a huge variety of commonly used products. These include shampoos, ^^^^^^^^^ soaps, face and body washes, toothpaste, washing up & laundry detergents and also industrial cleansing chemicals such as engine degreasers. ^^^^^^^^^^^^^^^^^ There are many derivatives of SLS that can be found in commercial preparations, including sodium laureth sulphate, sodium laureth-3 sulphate, and DEA or TEA sodium lauryl sulphate. Although these derivatives may vary slightly in mildness, the general action and effects are essentially similar. http://greenpeople.co.uk/Organics_Features_SLS.htm quote No mention of bubble bath, or use as an insecticide or bicycle cleaner there, but then aphids probably aren't to fussy in any case.

You may need to increase the amount if you are using scuffer/pleb brand stuff (17p/bottle). :-) |
