LIQUID BLEACH PRODUCTION
INTRODUCTION:
Bleach is a mixture or a single compound used to remove minor stains from white fabrics, ceramics, metals and related surfaces.
RAW MATERIAL REQUIREMENTS:
• Caustic Soda – It is a wetting agent here.
• Soda Ash – It helps to soften water and also cleans materials
• Sodium Hypochlorite – It is the bleaching agent that removes stains in materials
• Water – It helps to put all the materials in solution for easy use.
EQUIPMENT / TOOLS REQUIREMENTS:
• A mixer –m Manual or motorized. It should be low speed (200-500rpm).
• Filter Unit: (Manual or automatic)
• Filling / Packaging Unit – Used to fill the bottles. (It can be done manually or otherwise).
• Storage tanks, measuring devices, etc.
• Factory Wears/protectors.
PACKAGING MATERIALS:
Bleach can be packed in ½litre, 1litre, 5litres plastic or metal jerry cans. The cans should carry well made labels with he relevant information such as brand name, maker, instruction for use, etc. smaller packs like ½litre and 1litre can in turn be packed in cartons as needed by the users.
SPACE:
A standard room size space is enough for a small beginner to take off.
PRODUCTION METHOD:
(a) FORMULATION: 10 Litres Batch 100 Litres Batch
Sodium Hypo chlorite -0.5kg 5kg
Soda Ash -0.5kg 5kg
Caustic Soda -0.2kg 2kg
Water -8.7kg 87.5litres
Perfume -50mls 500mls
TOTAL -10LITRES 100 LITRES
Note: Bleach has a life span of about 2 years only.
METHOD: Mix all the ingredients except perfume in a suitable container. Keep for about 8-12 hours. Mix again very well. Keep for another 2-3 hours or when the materials clearly separates, decant the liquid portion, add perfume and pack as bleach. Filter press can be use to filter the product after the second mixing immediately.
PRODUCTION OF WHITE DISINFECTANT:
As earlier discussed, this disinfectant is based on PHENOLS or CRESOLS. It is a very powerful disinfectant used in heavily soiled areas such as Farms, Toilets, Hospitals etc.
FORMULATION I:
The formulation given below, is widely used all over the world as it meets all pharmaceutical requirements and regulatory bodies like NAFDAC. Usual precaution are however necessary.
20 Litres Batch
Sodium Stearate - 5kg
Cresol liquid (or Phenol) - 10litres
Distilled water (or others) - 5 litres
TOTAL - 20LITRES
It may be necessary to add more water and sieve after boiling. Kg can be used as parts.
PROCESSING:
Mix the sodium stearate, the cresol and water. Boil till the mixture dissolves. You may leave the mixture to stand for about one hour before boiling to see if dissolution can occur. If it does just warm the solution almost to boiling and pack. If not boil till all dissolves or for say 30 minutes. Pack when cold. You may need to filter.
FORMULATION II:
This is the commonest formulation among small scale manufactures. It is easy to make but profit is lower due to the use of phenol (disinfectant) concentrate.
20 Litres Batch Disinfectant Germicide
White Germicide Concentrate - 5 litres
Pine Oil - 2 litres
Genapol (or empicol) - 40mls (8TSP)
White Colourant Powder (optional) - 40g (8TSP)
Water - 12 litres
Total - 20 Litres
PRODUCTION METHOD:
1. Mix the concentrate with the genepol (or empicol) and add the pine oil. Then mix to fully blend. If not fully blended i.e. not homogeneous add a little extra genepol (about 1-2TSP).
2. When fully blended, add the need water and mix.
3. Add the white colourant if the colour is not whitish enough and mix till homogeneous.
Note: (I) Manual operation may take up to 50 minutes but mixing in a low speed mixer will be about 20 minutes for a small batch of less than 200 lites.
(II) The exact quantity of concentrate will depend on the quality of the one
in use. It may be more or less. Ask the supplier.
QUANTITY PARAMETERS:
Test in an approved laboratory for quality.
Note: This product, like other disinfectants require registration with NAFDAC
