1. Product Description
RXSOL Detergent Thickener Liquid is a specially formulated viscosity-enhancing additive developed for liquid dishwashing detergents, hand wash liquids, multipurpose cleaners and other surfactant-based cleaning products.
The product is designed to improve viscosity, consistency and formulation stability without significantly affecting cleaning performance when used at appropriate concentrations.
RXSOL Detergent Thickener helps manufacturers achieve a smooth, uniform and commercially attractive liquid detergent consistency while maintaining desirable foam characteristics.
It is particularly suitable for formulations containing SLES (Sodium Laureth Sulfate), AOS (Alpha Olefin Sulfonate), CAPB (Cocamidopropyl Betaine) and compatible non-ionic surfactants.
The product can reduce reliance on sodium chloride thickening in suitable detergent systems and offers improved formulation flexibility.

Frequently Asked Questions
Q1. Can RXSOL Thickener be used in SLES-based dishwashing liquid?
Yes. The proposed formulations are intended primarily for compatibility testing in SLES-based detergent systems.
Q2. Can it replace sodium chloride completely?
Possibly in some formulations, but not universally. Many SLES-based systems still require salt optimization.
Q3. Can it be used with AOS?
It may be suitable for AOS-containing detergents, but viscosity response can differ from SLES systems.
Q4. Does it increase cleaning performance?
The surfactant components can contribute to detergency and foaming, but the primary purpose of the product is viscosity modification.
Q5. What is the recommended starting dosage?
For laboratory development, start with approximately 2–3% and adjust based on the final detergent formulation.
Technical Recommendation for RXSOL Manufacturing
For commercial development, I would prioritize a CDEA-free, low-foam, easy-to-process liquid thickener, provided it achieves the required viscosity and cost targets. Formulation B is a starting point, not yet a validated production formula.
One important commercial distinction: the formulations above are surfactant-based viscosity boosters, not universal thickeners. Their performance depends strongly on the final detergent's surfactant system.
If your intended product is a concentrated liquid thickener that customers add at only 0.5–1% to increase dishwash viscosity substantially, a different formulation strategy using an optimized associative polymer or specialized rheology modifier may be more appropriate.
Alternative Formulation B – CDEA-Free Thickener
For manufacturers wishing to avoid Cocamide DEA, the following formulation may be evaluated.

PEG-150 Distearate is a non-ionic associative thickener commonly used in surfactant systems. However, it may require heating and controlled processing to dissolve properly.
Manufacturing note: PEG-150 Distearate may need processing around 65–75°C depending on grade and supplier recommendations. Confirm ingredient stability and the required addition sequence before manufacturing. This alternative has not been validated as a stable, pourable concentrate.

Target pH: Approximately 6.5–8.0 Target Viscosity: 2,000–5,000 mPa·s at 25°C, measured using a defined Brookfield spindle and speed.
These are development targets and must be confirmed experimentally.
Important: Salt Thickening Curve
When sodium chloride is used in a surfactant-based detergent, viscosity normally increases up to an optimum salt concentration and may then decrease if additional salt is added.
Therefore, sodium chloride should be added gradually, preferably as a premade solution, while checking viscosity after equilibration.
The correct thickener dosage and salt concentration should be determined together.

Function of Each Ingredient
1. Cocamidopropyl Betaine (CAPB)
-
Amphoteric surfactant.
-
Supports viscosity development in anionic surfactant systems.
-
Helps improve foam stability.
-
Contributes to detergent formulation compatibility.
2. Cocamide DEA (CDEA)
-
Non-ionic foam booster and viscosity enhancer.
-
Improves product body and foam stability.
-
Particularly effective in selected SLES-based detergent systems.
CDEA use requires review of applicable regulatory restrictions, impurity limits and nitrosamine-related controls. For new consumer formulations, a CDEA-free alternative may be preferable.
3. Lauramine Oxide
-
Amphoteric/non-ionic behaviour depending on pH.
-
Provides foam boosting and viscosity support.
-
Helps improve detergent performance.
4. Propylene Glycol
-
Functions as a coupling solvent.
-
Supports ingredient incorporation.
-
Can improve low-temperature handling in suitable formulations.
5. Sodium Citrate
-
Provides mild buffering.
-
Supports pH stability.
6. Demineralized Water
- Carrier and dilution medium.
Manufacturing Procedure – 100 KG
-
Charge approximately 20 kg of demineralized water into a clean stainless steel mixing vessel.
-
Start slow to moderate agitation.
-
Add sodium citrate and mix until dissolved.
-
