RXSOL Technical Data Sheet (TDS)

RXSOL Acid Thickener – HCl Toilet Cleaner & Descaling Gel

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

Product Description

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.

Proposed Technical Specifications

The following values are preliminary development targets, not verified specifications for an existing RXSOL commercial product.

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.

Applications

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.

Dosage

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.
 

Recommended Dosage

These are screening ranges only. Actual viscosity depends on the thickener chemistry, acid strength, surfactant concentration and formulation temperature.

Key Features and Benefits

• Provides viscosity development in compatible hydrochloric acid formulations.

• Improves cling on vertical toilet bowl and sanitary surfaces.

• Helps increase contact time for removal of mineral deposits.

• Suitable for developing acidic gel cleaners.

• Can improve uniform application and reduce rapid runoff.

• Designed for liquid blending and industrial manufacturing.

• Allows adjustment of viscosity through surfactant concentration.

• May provide additional wetting performance during cleaning.

Notes

Advantage : 
 

• Imparts very good viscosity at very low dosage.
• Gives a stable product without any fear of separation later.
• The product is almost colorless and transparent. This gives a very bright and sparkling final product on addition of dye.
• Turns out to be very economical because of the low dose.
• Easy to use readily miscible with water.
• Long term viscosity stability.
• Provides 90% corrosion inhibition in HCl.
• Solubilizes easily and quickly.

 Storage and Handling :-

The Product can be stored at ambient temperatures for five years. Avoid Contact with strong oxidizing agents .Do not store above 60 Deg C over prolonged periods . Should always be homogenized before use.

RXSOL Acid Thickener Manufacturing Formulation

100 KG Pilot Batch

Formulation A – Acid-Compatible Surfactant Thickener Concentrate

This is an experimental formulation based on an acid-compatible cationic surfactant and non-ionic co-surfactant system. It is not a verified commercial RXSOL formula.

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

1. Charge approximately 15 kg of demineralized water into a clean, compatible mixing vessel.

2. Start slow to moderate agitation.

3. Add propylene glycol and mix until uniform.

4. Slowly add CTAC 30% while maintaining agitation.

5. Add lauryl dimethyl amine oxide gradually.

6. Add the alcohol ethoxylate and continue mixing until homogeneous.

7. Add the remaining demineralized water to achieve a total batch weight of 100 kg.

8. Mix until uniform and allow entrained air to dissipate.

9. Check appearance, viscosity, specific gravity and phase stability.

10. 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.

Example Application: Thickened HCl Toilet Cleaner

100 KG Development Formulation – Approximately 10% HCl

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.

Quality Control Specifications for Final Acid Cleaner

Recommended Performance Testing

Acid Compatibility: Evaluate the thickener at 5%, 10% and 15% HCl concentrations.

Viscosity: Measure using a Brookfield viscometer at 25°C with a documented spindle and speed.

Vertical Surface Cling: Apply a standardized quantity to a reference acid-resistant surface and measure runoff.

Storage Stability: Evaluate samples at ambient and elevated temperatures using suitable sealed, compatible laboratory containers.

Cleaning Efficiency: Compare calcium carbonate removal under controlled conditions against an unthickened acid cleaner.

Corrosion Compatibility: Conduct material-specific testing for any metal cleaning application.

 Frequently Asked Questions

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.

Manufacturing Recommendation

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.

Supply location

Storage and Handling

Store the thickener concentrate in clean, tightly closed HDPE or other compatible containers.

Keep away from excessive heat, direct sunlight and incompatible chemicals.

For acid-containing finished products, use only packaging validated for the specific hydrochloric acid concentration.
