Soap-based surface cleaner with Potassium Oleate

Indicative household cleaning formula with an alkaline potassium soap base.

Save to favourites
This recipe is intended as an indicative household cleaning formula, not a cosmetic. It uses a potassium soap base with an alkaline pH, so it must not be treated as a shower gel or facial cleanser. Potassium Oleate is formulated as the main base for its liquid potassium soap profile and alkaline character. The recipe is intended for gentle household cleaning, not as a facial, body or hair product. It must be prepared in a small batch and validated before scaling up: pH, smell, colour, container compatibility, stability, separation and performance on the surfaces where it will be used.

Step by step

Prepare the equipment and protective gear 1 Room temperature

Prepare the equipment and protective gear

Clean the workspace and prepare a mixing beaker, spatula, scales, pH meter and final container. Wear gloves if handling a larger quantity or if you have sensitive skin.

Although this is a simple recipe, it uses an alkaline soap base, so it is advisable to avoid splashes and work slowly.

Weigh the water and soap base 2 Room temperature

Weigh the water and soap base

Weigh the distilled water, then add Potassium Oleate little by little. It is the main ingredient and should be mixed without vigorous whisking.

If you stir too energetically, foam will appear and make it difficult to see whether the mixture is truly uniform.

Add the glycerine 3 Room temperature

Add the glycerine

Add the glycerine and mix slowly. Its role here is to modify the feel slightly and help the formula feel less dry during handling.

Do not add fragrance, essential oils or colourants to this base formula until stability and compatibility have been validated.

Measure the pH without acidifying as for a cosmetic 4 Room temperature

Measure the pH without acidifying as for a cosmetic

Measure and record the final pH. It is expected to be alkaline because of the nature of the soap base.

Do not try to lower it to pH 5-6 as though it were a shower gel. With potassium soaps, aggressive acidification can break the formula or cause precipitation.

Package and label 5 Room temperature

Package and label

Transfer to a clean bottle that is resistant to the product. Label it with the name, date and a household-use warning.

Do not present it as a cosmetic or disinfectant. It is a proposed soap-based cleaner that must be validated on the surfaces where it will be used.

Test on a small surface Final Room temperature

Test on a small surface

Before general use, test a small amount on an inconspicuous area. Rinse if a soapy residue remains or if the surface requires it.

Avoid marble, natural stone, untested aluminium and delicate surfaces sensitive to alkaline products.

Preservation, shelf life and validation

  • Indicative use for household cleaning. It is not a disinfectant. Wear gloves if you have sensitive skin or for prolonged use.
  • Do not use on marble, natural stone, untested aluminium, delicate surfaces or materials sensitive to alkaline products. Always test on an inconspicuous area.
