Applications of Aluminum Chlorohydrate in Industrial Manufacturing

Aluminum chlorohydrate serves as a critical specialty raw material in multiple industrial operations, delivering reliable results across water treatment, personal care production, paper manufacturing, textile finishing, and oil & gas processes. As the direct manufacturer, we supply high-purity aluminum chlorohydrate tailored for large-scale integration by leading firms worldwide.

1. Municipal Drinking Water Purification

Municipal water authorities use aluminum chlorohydrate as a highly efficient coagulant to remove turbidity, heavy metals, and organic contaminants from raw water. Its rapid hydrolysis and lower residual aluminum compared to conventional alum minimize treatment risks in large-scale potable water plants. The flocculation process enhances sedimentation, optimizes filter loading, and aids compliance with public health regulations.

Industry compliance standards

• NSF/ANSI 60: Drinking Water Treatment Chemicals – Health Effects
• EN 883: Chemicals used for treatment of water intended for human consumption – Polyaluminum chloride and polyaluminum compounds
• US EPA Safe Drinking Water Act (SDWA) treatment chemical requirements
• Chinese Standard GB 15892-2009: Water treatment chemicals Polymeric aluminum chloride

Typical usage ratio

• Ranging from 5 to 30 mg/L, dosage varies with influent water turbidity, organic load, and local regulations. Lower dosages apply for treated surface water, higher for high-turbidity sources.

Downstream process integration

• Automatically dosed into rapid mixing tanks after raw water intake.
• Followed by flocculation, sedimentation, filtration, and disinfection stages.
• Real-time automation adjusts dosing based on online turbidity and TOC meters.

Final product types

• Municipal drinking water
• Bottled water for public distribution
• Food-grade process water

2. Antiperspirant Manufacturing in Personal Care

Cosmetic manufacturers incorporate aluminum chlorohydrate as the active ingredient in aerosol and roll-on antiperspirant deodorant products. With astringent properties and low skin irritation risk, it reduces perspiration by reacting with eccrine gland secretions, forming temporary gel plugs and tightening skin pores. Production adheres to strict GMP and product safety systems for dermal applications.

Industry compliance standards

• U.S. FDA 21 CFR 350.60: OTC Antiperspirant Drug Products Monograph
• EU Regulation (EC) No 1223/2009: Cosmetic Products Regulation
• ISO 22716: Cosmetics – GMP Guidelines
• IFRA Guidelines on dermal safety

Typical usage ratio

• Active concentration typically at 8% to 25% in finished antiperspirant formulations, depending on delivery form and market regulation; precise dosing adapted per efficacy and skin tolerance testing.

Downstream process integration

• Dissolved in deionized water or ethanol during primary batch preparation.
• Blended with emollients, propellants (for aerosols), and other actives before filling.
• QC sampling ensures active level consistency and microbiological safety.

Final product types

• Roll-on antiperspirant lotions
• Aerosol spray antiperspirants
• Antiperspirant sticks and gels
• Personal cleansing wipes

3. Paper Manufacturing: Wet-End Additive

Pulp and paper mills add aluminum chlorohydrate in the wet-end section to improve retention of fine particles, fillers, and sizing agents. It enhances flocculation, charges neutralization, and pitch control in acidic or mildly alkaline papermaking systems. Its high cationic charge density helps reduce the need for additional retention aids, increases machine runnability, and improves final sheet properties for packaging and print substrates.

Industry compliance standards

• FDA 21 CFR 176.170: Components of paper and paperboard in contact with aqueous and fatty foods
• ISO 9001: Quality management for industrial process control
• REACH registered for use in pulp and paper industries
• EN 646: Paper and board intended to come into contact with foodstuffs

Typical usage ratio

• Usually dosed at 0.01% to 0.05% by weight, depending on furnish composition, stream, and desired retention effect. Higher dosages may address critical sizing or contaminant issues.

Downstream process integration

• Pumped into mixing chests after fiber slurry preparation, before headbox entry.
• Mixed with other process additives such as rosin, synthetic retention aids, and fillers.
• Inline instrumentation monitors charge demand and solids balance to set dosing rate.

Final product types

• Food contact packaging papers
• Printing and writing papers
• Paperboard for folding cartons
• Specialty technical papers

4. Textile Wastewater Treatment in Dyeing Plants

Dyeing and finishing factories deploy aluminum chlorohydrate for primary and secondary clarification of colored and surfactant-laden wastewater. The material acts as a coagulant, promoting precipitation of suspended solids, dye molecules, and emulsified fats during physico-chemical treatment. This step enables compliance with stringent effluent discharge permits and supports in-plant water recycling systems.

Industry compliance standards

• OECD Guidelines for Testing Chemicals: Water Treatment Guidelines
• GB 4287-2012: Discharge standard of water pollutants for dyeing and finishing of textile industry (China)
• ISO 14001: Environmental Management Systems for industrial operations
• Local Environmental Protection Agency (EPA) discharge permits

Typical usage ratio

• Dosage varies from 30 to 100 mg/L, depending on influent dye load, COD level, and the need for color removal versus solids reduction. Operators adjust with jar tests for best results.

Downstream process integration

• Dosed at equalization tank or primary clarifier inlet, mixed with auxiliary coagulants if necessary.
• Followed by mechanical flocculation, sedimentation, and, if needed, secondary biological treatment stages.
• Effluent color and turbidity detectors control adjustments of input levels.

Final product types

• Treated effluent for direct discharge
• Process water for internal recycling
• Sludge for disposal or further dewatering

5. Enhanced Oil Recovery: Drilling Mud and Fracturing Fluid Additive

Oilfield service companies employ aluminum chlorohydrate as a viscosity modifier and clay stabilizer in water-based drilling muds and fracturing fluids. Its addition controls the swelling of reactive shale and improves the separation of drill cuttings. Use in high-salinity or temperature conditions provides operational advantages over traditional iron or alum-based products.

Industry compliance standards

• API Recommended Practice 13B-1: Field Testing Water-Based Drilling Fluids
• ISO 9001:2015 certified production and QA systems for oilfield additives
• REACH registration for oil & gas use
• OSHA HAZCOM compliance for worker handling

Typical usage ratio

• Common application ranges from 0.2% to 2% by weight of total fluid content; mud engineers adjust based on wellbore geology and downhole conditions.

Downstream process integration

• Mixed with other functional additives such as biocides, surfactants, and salt during on-site fluid preparation.
• Continuous dosing into circulating mud tanks throughout drilling or fracturing operations.
• Rheology and solids control units measure real-time impact.

Final product types

• Oil and gas well borehole fluids
• Produced water for reinjection or disposal
