These two products sell together and must never be used together. An acidic toilet cleaner poured into a bowl that has just had bleach in it releases chlorine gas, and it happens in Kenyan homes and hotels every year.
Acidic toilet bowl cleaner
The working part is hydrochloric acid at around 5 per cent in the finished product, thickened so it clings to the bowl rather than running straight into the water. Some producers use sulphamic acid instead, which is milder to handle and less aggressive on plumbing, at a somewhat higher material cost. For a first product, sulphamic is the safer choice.
Handling acid
Always acid into water. Always outdoors or with real ventilation. Always an HDPE container, never metal. Gloves and splash goggles, and running water within reach. This is not a product to make casually in a kitchen.
Pine disinfectant
Pine gel and pine disinfectant are enormous sellers in Kenya, largely on smell. That is worth understanding: much of what is sold as disinfectant is scented cleaner with little real biocidal action. If you want a product institutions will accept, include a proper active such as benzalkonium chloride and be able to state the concentration.
Getting a stable emulsion
Pine oil does not dissolve in water. It needs an emulsifier and steady stirring into warm water. Rush it and the batch separates into an oily layer within a day. Add the pine oil to the water in a thin stream, not all at once.
Concentrate versus ready to use
For cleaning contractors and institutions, sell the concentrate. A 20 litre drum of disinfectant concentrate makes several hundred litres at the site, and you are not paying to truck water around Nairobi. Supply a marked dosing bottle with it, otherwise it will be used at four times the rate.
The label
Both products need clear hazard wording, and the toilet cleaner needs the bleach warning in a size somebody will actually read. This is not only a safety matter, a serious incident traced to an unlabelled product will end a small business.
Materials used in this guide
Do you provide Safety Data Sheets?
Yes, for every chemical line, in the standard sixteen-section format, and before you buy rather than after. Message the product name and we will send the PDF the same day.
Can I get a certificate of analysis?
Yes, on request, for the specific batch supplied. Institutional buyers and anyone submitting to KEBS usually needs one.
What must never be mixed?
Bleach with any acidic cleaner, which releases chlorine gas. That single mistake causes more injuries in Kenyan cleaning work than anything else. Keep hypochlorite away from hydrochloric acid, sulphamic descalers and acidic toilet cleaners.
How should caustic soda be handled?
Add the flakes slowly to cold water while stirring, never the other way round and never in a sealed or glass container. The solution heats sharply. Gloves and splash goggles, not spectacles.
How do I store chemicals safely?
Off the floor, out of the sun, ventilated and lockable. Acids apart from alkalis, and both apart from hypochlorite. Peroxide and hypochlorite lose strength in heat, so avoid a metal store under an iron roof.
Do I need a KEBS permit to sell what I make?
If you are selling a finished cleaning product commercially, yes, and the applicable standard depends on the product. Start the process early. We can tell you which standard usually applies, though we are not a certification body.
