Material compatibility: Hydrochloric acid can aggressively attack many metals, cementitious materials, natural stone and certain coatings. A thickener does not make HCl safe for these surfaces. Metal descaling requires a separately validated corrosion inhibitor system.
It is used as viscosity builder in acid cleaning and the dosage suggested for building viscosity is 2 to 2.4% depending upon the acid content.

Estimated surfactant active matter: Approximately 26%, assuming the alcohol ethoxylate is 100% active.
Function of Each Ingredient
Cetrimonium Chloride (CTAC)
A cationic surfactant that can participate in viscosity development in selected acidic surfactant systems. Its performance depends on the formulation and counterion environment.
Lauryl Dimethyl Amine Oxide
A surfactant that becomes predominantly protonated under strongly acidic conditions. It may contribute to wetting and viscosity development when paired with compatible surfactants.
C12–15 Alcohol Ethoxylate
Provides additional wetting and helps improve the distribution of cleaning solution across contaminated surfaces.
Propylene Glycol
Acts as a coupling solvent and formulation aid.
Demineralized Water
Serves as the carrier for the liquid concentrate.
Manufacturing Procedure – 100 KG
-
Charge approximately 15 kg of demineralized water into a clean, compatible mixing vessel.
-
Start slow to moderate agitation.
-
Add propylene glycol and mix until uniform.
-
Slowly add CTAC 30% while maintaining agitation.
-
Add lauryl dimethyl amine oxide gradually.
-
Add the alcohol ethoxylate and continue mixing until homogeneous.
-
Add the remaining demineralized water to achieve a total batch weight of 100 kg.
-
Mix until uniform and allow entrained air to dissipate.
-
Check appearance, viscosity, specific gravity and phase stability.
-
Package in compatible, labelled containers.
Processing temperature: Preferably 20–35°C, subject to raw-material handling requirements.
Do not add concentrated hydrochloric acid during the manufacture of this thickener concentrate. Acid compatibility should be evaluated separately using controlled laboratory trials.

The formulation contains approximately 10% active HCl by weight before considering impurities and assay variations.
Important: This is a composition for controlled laboratory development, not a validated production recipe. The proposed surfactant system may not achieve the desired gel viscosity at this acid concentration.
Acid Mixing Safety
Hydrochloric acid is corrosive and can release irritating hydrogen chloride vapours.
Manufacturing requires acid-compatible equipment, local exhaust ventilation, appropriate PPE and trained personnel. Always add acid slowly to water under controlled conditions; never add water to concentrated acid.
Do not mix hydrochloric acid cleaners with sodium hypochlorite, bleach or other oxidizing cleaning products because toxic chlorine gas may be released.
RXSOL Technical Product Bulletin
Acid Thickener for Hydrochloric Acid Cleaning Formulations
Working Principle
RXSOL Acid Thickener is designed to modify the rheological behaviour of acid-based cleaning solutions.
Selected cationic and protonated amphoteric surfactants can form organized aggregates in acidic media. Under suitable conditions, these structures can increase viscosity and improve surface cling.
However, strong acid concentration, chloride ion concentration and surfactant ratio strongly influence aggregate formation. The result may range from a low-viscosity liquid to a viscous solution or an unstable separated system.
Consequently, the viscosity of the final acid cleaner must be demonstrated experimentally rather than inferred from the thickener composition alone.
