This is the conversation we have across the counter several times a week. It is worth writing down properly, including the parts that are not encouraging.

What it costs to start

At the smallest honest scale, one product, trial quantities, a drum, a paddle and a scale, you are looking at somewhere between eight and fifteen thousand shillings to make your first sellable batch of liquid soap, including packaging. That figure surprises people in both directions. It is lower than most expect for materials and higher than most expect once jerry cans, caps and labels are counted.

To run properly, two or three products, 25 kg pack sizes, a few hundred litres a month, printed labels, budget somewhere between eighty and two hundred thousand shillings in working capital, most of it tied up in stock and packaging rather than equipment.

Permits and standards

If you are selling to shops, institutions or anywhere with a procurement process, you need a KEBS permit for the product category, and the applicable standard depends on what you are making. Start the process early: sample testing takes time, and a failed sample means reformulating and resubmitting. County business permits and, for anything at scale, NEMA compliance on effluent also apply. The KEBS site is the authority on which standard applies; we can tell you what a laboratory will typically look for.

Realistic margins

Gross margin on well-made liquid soap and dishwashing liquid sold in your own packaging is healthy, frequently 40 to 60 per cent. What erodes it is transport, breakage, credit given to shops that pay late, and the discounting that starts the moment a competitor opens down the road. Bleach margins are thin because of weight. Softener and handwash margins are the best, because customers pay for scent and feel.

The three reasons small producers close

Inconsistency. Batch to batch variation loses customers faster than price. Weigh, do not estimate. Write down what you did.

Underpricing. New producers price against the cheapest thing on the shelf, forget packaging and transport, and discover after four months that they have been working for nothing.

Credit. Supplying shops on credit to win the account, then carrying two months of unpaid stock. Cash or M-Pesa on delivery until a relationship is proven.

What actually works

Pick one product and get it genuinely good before adding a second. Sell locally first, where you can deliver on a boda and collect the money yourself. Get the label right, in this market a professional label and an induction seal are worth more than another percent of active. And keep a notebook: batch date, quantities, what the customer said. That notebook becomes your quality system when you apply for a permit.

A multipurpose cleaner is the easiest second product to add to a soap line, because most of the materials are already in your store. The interesting version is the concentrate.

Surface safety

A strongly alkaline cleaner will dull polished terrazzo, mark aluminium and strip floor polish. Most Kenyan offices and homes have terrazzo, tile or vinyl, so a mildly alkaline product around pH 9 to 10 covers nearly everything safely. Save the aggressive alkaline degreaser for kitchens and workshops, and sell it as a separate product with its own label.

Why butyl glycol earns its place

Water and surfactant will wet a greasy floor but not dissolve the film. Butyl glycol does, which is the difference between a floor that looks clean when wet and one that looks clean when dry. It is not expensive at the levels used.

The concentrate argument

Sell a cleaning contractor a 20 litre drum of ready-to-use cleaner and you have sold them 19 litres of water and a delivery charge. Sell the same drum at four times strength and they make 80 litres on site for the same freight. They save money, you sell a higher-value drum, and everyone stops paying to move water around Nairobi.

The one thing you must supply with it is a dosing measure. Without one, cleaners will pour by eye, use it at four times the rate, and conclude the product is expensive.

Scented floor cleaner as a retail line

In the retail market, fragrance sells this product almost entirely. Lemon and pine dominate, lavender does well in higher-income estates. Keep the colour consistent batch to batch, customers notice a shade change and read it as a change in the product.

Powder is a different business from liquids. You need dry storage, a way to tumble or blend evenly, and the discipline to pack the same day. Get those right and it is a high-volume product with a long shelf life.

What the ingredients actually do

Soda ash provides alkalinity, which is most of the cleaning in a powder. Sodium sulphate is a filler and flow aid, every commercial powder has a lot of it, and there is no shame in that as long as your active level is honest. STPP or zeolite deals with hard water. CMC stops the dirt you lifted from settling back on the cloth. Optical brightener makes whites look whiter under daylight without actually removing anything.

Moisture is the whole game

Soda ash is hygroscopic, it pulls water out of the air and turns your free-flowing powder into a brick. Store bags off the floor on pallets, keep the blending area covered, and pack finished powder the day you make it. If your product cakes in the shop, you will not get a second order.

Are enzymes worth it?

For a budget powder sold on price, no. For anything positioning itself above the cheapest shelf, yes, protease and amylase do visible work on food and body-soil stains that no amount of soda ash achieves. They are the most expensive component per kilo, so add them last, at ambient temperature, and never store the finished powder anywhere hot.

Hand wash versus machine

Most Kenyan laundry is still done by hand, so foam matters more than it does in Europe. A low-foam machine formulation will be rejected by hand washers who read foam as strength. If you are selling into both markets, make two versions rather than compromising.

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.

Handwash is the product institutions buy in volume, schools, hospitals, hotels, offices, and it is the one where cutting corners shows up fastest, because people use it many times a day on their hands.

The pH question

Healthy skin sits at about pH 5.5. A handwash at pH 8 or 9 strips the skin barrier and, with repeated use, leaves hands dry and cracked. Bringing your batch down to 5.5 to 6 with citric acid costs almost nothing and is the single most important thing you can do for the product. It is also the first thing a hospital procurement officer will ask about.

Formulation for 20 litres

Making shower gel from the same base

Increase the glycerine to about 400 g, lift the CAPB slightly, choose a richer fragrance and add a pearlising agent if you want the opaque look. The rest is identical. Being able to run two products off one base is what makes this worth setting up.

Antibacterial claims

Be careful here. Adding a biocide and printing the word antibacterial on the label brings you into regulated territory, and institutional buyers will ask for substantiation. If you want to make the claim, talk to us about which active is appropriate and what testing you will need first.

Packaging for institutions

Schools and hospitals mostly want 5 litre refill cans for wall dispensers, not retail bottles. That is cheaper for them and cheaper for you. Offer both, and price the 5 litre so that switching to it is obviously the sensible choice.

Fabric softener is one of the better products a small Kenyan producer can make. Material cost per litre is moderate, the perceived value is high because of the scent, and repeat purchase is strong.

What makes softener different

Unlike detergents, softener works from a cationic (positively charged) material that deposits onto fabric. That has two consequences. It must never be mixed with your detergent line in the same equipment without a proper wash between, because cationic and anionic materials neutralise each other. And it needs an acidic pH to stay stable, which is the opposite of everything else on your shelf.

Formulation for 20 litres

The mistakes that cost batches

Cold water. The base will not emulsify properly and the batch separates within days into a watery layer and a creamy one.

Fragrance added hot. Above about 35 degrees you lose the top notes to evaporation. Wait for it to cool.

Alkaline pH. Softener drifting above pH 6 will thicken oddly and then break.

Shared equipment. Traces of your dishwashing liquid in the drum will curdle a softener batch. Wash properly or keep a dedicated drum.

Fragrance is the product

Customers cannot see softness, so they judge on smell, in the bottle, in the wash, and on the clothes an hour later. Buy a fragrance with reasonable substantivity rather than the cheapest one that smells strong in the bottle. It is worth paying more here than anywhere else in the formulation.

Costing

Materials come to roughly two and a half to three thousand shillings for 20 litres depending on how heavily you load the fragrance. That is comfortably below what softener sells for in 500 ml and 1 litre packs, which is why it is worth the extra care in the mixing.

Bleach is the easiest cleaning product to make and the easiest to make badly. There is no real formulation, it is dilution, stabilisation and packaging, but each of those three has a trap in it.

Start with real strength material

Sodium hypochlorite is sold at 12 to 14 per cent available chlorine, and it loses strength from the day it is made. Heat accelerates it dramatically. Material that has sat in a hot store for two months may be well below its label, so buy from somewhere with turnover and check the strength rather than trusting the drum.

Dilution

For household bleach at roughly 3.5 per cent, one part of 14 per cent hypochlorite to three parts water gets you close. For a 3 per cent product, one part to four. Always add hypochlorite to water, never water to hypochlorite, and never in a metal container.

Why your bleach goes weak

Three reasons, in order of frequency: it was stored in the sun or under an iron roof; the pH drifted down, because hypochlorite is only stable when alkaline; or it was made with hard water, and the metal ions in it catalyse decomposition. A small amount of caustic soda fixes the second, soft water fixes the third, and a shaded store fixes the first.

The packaging trap

Bleach generates gas as it decomposes. In a sealed bottle with a plain cap, pressure builds and eventually the bottle bulges or the cap fires off when a customer opens it. Use vented caps, or at minimum leave proper headspace and warn on the label. Never pack bleach into recycled soda bottles.

Safety, without the lecture

Bleach with any acid produces chlorine gas. This is the most common serious chemical injury in Kenyan cleaning work, and it usually happens when someone pours bleach into a toilet that has just had an acidic cleaner in it. Print the warning on your label. It costs nothing and it protects your brand as well as your customer.

Costing

Hypochlorite is cheap and water is cheaper, so the material cost per litre is very low. The problem is that bleach is heavy, low value and expensive to move, so the margin lives or dies on how far it travels. It works best sold locally in volume, or as a companion product alongside higher-margin lines.

If you want to go further

Thickened bleach with a small amount of surfactant clings to toilet bowls and sells at a premium. Scented bleach needs a fragrance rated for hypochlorite, because most fragrance oils are destroyed by it, ask us which ones survive before you waste a batch.

Dishwashing liquid is where most small Kenyan producers make their money, because every household and every kibanda buys it weekly. The chemistry is close to liquid soap, but two changes separate a product people repurchase from one they try once.

The two changes that matter

The first is CAPB. Cocamidopropyl betaine costs more than the other surfactants but it makes the product noticeably gentler on hands. Anyone washing dishes for a restaurant or a family notices within a week, and it is the reason they come back.

The second is raising the LABSA slightly against the liquid soap recipe. Grease on Kenyan cookware, chapati oil, nyama choma fat, githeri residue, needs more detergency than a general purpose soap provides.

Formulation for 20 litres

Method

Follow the same order as liquid soap: soften, neutralise, surfactants, additives, thicken, rest. Add the CAPB after the SLES and before the CDEA. Keep the stirring slow throughout.

Getting the appearance right

Kenyan buyers associate a slightly viscous, clear green or yellow liquid with strength. A cloudy product reads as watered down even when it is not. If yours is hazy, the usual cause is hard water or fragrance added too fast without enough solubiliser, try adding the fragrance premixed into a little of the CAPB.

Costing and pricing

Materials for 20 litres run to roughly three and a half thousand shillings, about 175 shillings a litre. In 500 ml bottles with a label you are looking at a landed cost around 130 to 150 shillings a bottle depending on your packaging source. Retail in most estates sits well above that, which is why the product works.

Selling it

Refill stations do very well in Kenya, customers bring their own bottle and pay less, you save on packaging. If you go that route, keep a 20 litre jerry can with a tap and a measuring jug, and label the tank with the batch date.

This is the formulation we hand over the counter to people starting out. It makes about 20 litres, costs a little over three thousand shillings in materials at current prices, and produces a soap that stands comparison with what is on the shelf.

What you need for 20 litres

The method

1. Soften the water first

Most of Nairobi, Kiambu, Machakos and the Rift is on hard water, and borehole supply is harder still. Calcium and magnesium tie up your surfactant, which is why a recipe that foams beautifully in a video foams poorly in a Kariobangi workshop. Dissolve the EDTA or STPP in the water before anything else goes in.

2. Neutralise the LABSA properly

Dissolve the caustic soda in cold water in its own bucket, never the other way round, and let it cool, the solution gets genuinely hot. Add the LABSA to the drum, then trickle the caustic solution in while stirring. Check with pH paper and stop between 7 and 8. Too low and the product stings; too high and it will irritate skin and eat at your packaging.

3. Add the SLES slowly

SLES 70 is a thick paste. Warm it slightly if it is stiff, and stir it in gently. Whipping air into the batch at this stage is the single most common cause of a product that looks like a milkshake for two days.

4. CDEA, then the finishing materials

The CDEA gives the foam its density and adds body. After it is uniform, add preservative, then colour, then fragrance. Fragrance last, because it is the most volatile and the most expensive thing in the drum.

5. Thicken with brine, carefully

Never throw dry salt into the batch, it sits at the bottom and you overdo it. Make a brine and add it a little at a time. Viscosity climbs, peaks, then falls, and once you are past the peak there is no coming back. Stop a shade thinner than you want, because it will firm up overnight.

6. Rest it

Leave the drum covered overnight. Air comes out, the colour evens, and you can check the pH once more before packing.

What it costs

At current published prices the chemicals for a 20 litre batch come to roughly three thousand shillings, which is about 150 shillings a litre. Then add your packaging: four 5 litre jerry cans and caps, or twenty 1 litre bottles with labels. Packaging is usually a third of the total cost, and it is what new producers forget when they set a price. See the packaging page for those figures.

Where it usually goes wrong

It came out thin and will not thicken. Too much salt, or not enough CDEA. If you are past the salt peak, the fix is to blend in a fresh batch made without salt.

It separates after a week. Usually poor mixing of the CDEA, or fragrance added to a batch that was too warm.

It smells sour after a month. No preservative, or not enough. Water-based products in a warm store will grow something.

It stings hands. pH too high. Check with paper, not by eye.

Scaling up

The recipe scales linearly. At 200 litres a month you should stop buying 5 kg pails and move to 25 kg, which is where the margin improves noticeably. At a tonne, drums make sense if you have somewhere safe and cool to keep them.
