Acid Thickener Rx is a nonionic surfactant designed to build viscosity in acid media. Acid Thickener Rx surfactant may be used alone in hydrochloric acid, or in combination with sodium chloride (salt) when used with other acids (such as phosphoric, sulfuric, hydrofluoric, citric, oxalic, etc.) Varying the use level of Acid Thickener surfactant (and salt) will vary the viscosity build. Acid Thickener Rx is a versitle, broad spectrum non phenolic biocide & Fungicide for leather, paper, paint, textile,wood and water treatment , free from penta - chlorophenate.
Product Name: RXSOL Acid Thickener Product Category: Acid-Compatible Surfactant Thickener Chemical Nature: Cationic / Non-Ionic Surfactant Blend Application: Hydrochloric Acid Toilet Cleaner, Acidic Descaling Gel, Sanitary Cleaner and Industrial Acid Cleaning Formulations Product Code: To be assigned Physical Form: Liquid Concentrate
RXSOL Acid Thickener is a specialty surfactant-based viscosity modifier developed for manufacturing hydrochloric acid-based toilet cleaners, bathroom descalers and industrial acid cleaning gels.
The product is designed to increase the viscosity of compatible acidic cleaning formulations, improving adhesion to vertical surfaces and extending the contact time between the cleaning solution and mineral deposits.
Unlike conventional detergent thickeners, which may lose viscosity or become unstable in strongly acidic solutions, RXSOL Acid Thickener is intended for use in hydrochloric acid formulations after appropriate compatibility and stability testing.
The thickened acidic formulation helps improve the removal of calcium carbonate deposits, lime scale, rust stains and mineral contamination from compatible acid-resistant surfaces.
It is an ethoxylate for preparing high viscosity acid solutions and thus is commonly known as acid thickener. It is most predominantly used in preparing liquid toilet cleaner based on hydrochloric acid.

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.
Q1. Can RXSOL Acid Thickener be used in 33% hydrochloric acid?
Compatibility at 33% HCl has not been established. This proposed formulation is intended for evaluation in lower-acid formulations, initially around 5–15% HCl.
Q2. Can normal detergent thickener be used for HCl toilet cleaner?
Most conventional detergent thickeners are not designed for strong acidic conditions and may lose viscosity or separate.
Q3. Can this thickener be used for industrial descaling?
It may be evaluated for localized acid descaling gels, but corrosion inhibitor compatibility and equipment metallurgy must be assessed separately.
Q4. Is the formulation transparent?
A clear appearance is possible, but cannot be guaranteed without formulation and stability testing.
Q5. What is the recommended dosage?
An initial screening range of 1–5% is proposed. The optimum dose must be determined by viscosity and stability testing.
For a commercial RXSOL acid thickener, the most important objective is to achieve repeatable viscosity development at the customer's actual HCl concentration.
I recommend conducting a pilot evaluation at three acid concentrations—5%, 10% and 15%—and measuring viscosity, phase stability and surface cling before finalizing the TDS.
A CTAC/amine oxide blend is only one possible approach. A purpose-designed acid thickener based on suitable long-chain amine or quaternary ammonium surfactant chemistry may perform better, but must be selected using supplier compatibility data and actual laboratory testing.
One important question: Do you want the RXSOL Acid Thickener to work mainly with 10–12% HCl toilet cleaner, or with 20–33% HCl industrial descaling acid? The required surfactant chemistry and achievable viscosity can differ substantially.
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.
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.
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.

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.
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 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.
