Dishwash liquid is one of the most widely used household cleaning products, used for removing grease, oil, food residues and general dirt from utensils and kitchenware. A properly balanced formulation should provide good cleaning performance, adequate foam, pleasant fragrance and suitable viscosity.
This article covers Dishwash Liquid Formulation 1 from the provided professional cleaning formulation book. The formulation is designed as a practical manufacturing formula and includes surfactants, chelating agent, neutralized LABSA, viscosity builder, preservative, perfume and colour.

Important: The quantities of caustic soda and salt may need adjustment depending on the quality of the acid slurry, SLES and the desired viscosity.
Manufacturing Process
Step 1 – Neutralization of LABSA
Take 3 kg LABSA and mix it with 8 kg water.
Separately dissolve 600 g caustic soda in 2 kg water.
Add the caustic soda solution gradually to the diluted LABSA while mixing. The formulation instructs to neutralize the acid slurry to approximately pH 7.
Always add the caustic solution carefully and control the pH rather than relying only on a fixed quantity.
Step 2 – Prepare the Main Water Phase
Take the required 70 kg water in the mixing vessel.
Add:
- Di Sodium EDTA – 600 g
- CMIT/MIT – 50 g
Mix properly until uniformly dispersed/dissolved as appropriate for the materials being used.
Step 3 – Add SLES
Add 13 kg SLES 28% slowly into the main batch.
Maintain moderate agitation to avoid unnecessarily excessive air incorporation.
Step 4 – Add CDEA
Add 1 kg CDEA and mix until the batch becomes uniform.
CDEA is included in the formulation as part of the surfactant/thickening system.
Step 5 – Add Neutralized LABSA
Now slowly add the previously neutralized LABSA solution to the main batch.
Mix thoroughly until the formulation becomes homogeneous.
Step 6 – Adjust pH
Add 500 g citric acid gradually and adjust the finished product to approximately pH 6, as specified in the formulation.
The exact amount required can vary, so pH should be checked during manufacturing.
Step 7 – Add Perfume and Colour
Add:
- Water-soluble perfume – 100 g
- Food colour – 10 g
Mix gently until the perfume and colour are uniformly distributed.
Step 8 – Adjust Viscosity with Salt
Prepare the 2.5 kg salt as appropriate for addition and add it at the end.
The source specifically recommends adding salt at the end and waiting 24 hours before judging the final viscosity.
Salt should not automatically be assumed to work better at higher concentrations; the required amount depends on the raw materials and desired consistency.
Expected Product Characteristics
The formulation is intended to produce a liquid dishwash with:
- Good cleaning action
- Foaming from the surfactant system
- Suitable viscosity after salt adjustment
- Pleasant fragrance
- Controlled pH
- Uniform appearance
The exact viscosity can vary according to the quality of SLES, LABSA and salt, so the source recommends testing a small batch first.
Role of the Main Ingredients
SLES 28%
The primary surfactant component of the formulation, contributing to cleansing and foam.
LABSA
A strong anionic surfactant that contributes significantly to detergency. It is first neutralized with caustic soda before being incorporated into the formulation.
CDEA
Used as part of the formulation’s surfactant system and contributes to foam and viscosity.
Di Sodium EDTA
Included as a chelating agent in the formulation.
Caustic Soda
Used for neutralizing LABSA. The quantity may vary depending on the acid slurry quality and actual neutralization requirement.
Citric Acid
Used for final pH adjustment.
Salt
Used for viscosity adjustment. The source specifically recommends adding it at the end and checking the viscosity after 24 hours.
CMIT/MIT
Used as the preservative system specified in this formulation.
Water-Soluble Perfume
Provides fragrance to the finished dishwash.
Colour
Provides the desired product appearance.
Important Manufacturing Tips
1. Always check pH.
Do not depend solely on the listed quantities of caustic soda or citric acid.
2. Don’t add all the salt at once.
Salt has a major effect on viscosity, and the source recommends adding it at the end and evaluating the product after 24 hours.
3. Make a small trial batch first.
Raw-material quality can change the final result considerably. The source itself recommends small-batch testing before moving to large-scale production.
4. Control mixing.
Excessive agitation can introduce unnecessary air and make it difficult to judge the final appearance and viscosity.
Conclusion
This 100 kg Dishwash Liquid Formulation 1 uses a combination of SLES, neutralized LABSA and CDEA to create the primary cleaning system, supported by EDTA, preservative, perfume, colour and salt-based viscosity adjustment. The formulation specifies approximately pH 6 for the finished product and recommends allowing 24 hours after salt addition before evaluating the final viscosity.
Note: The source recommends making small batches first because raw-material quality can affect the required quantities, particularly caustic soda and salt.
