High Basicity Aluminum Chlorohydrate (ACH) with High Al2O3 Content from China Suppliers and Factory
Core Features
●
High degree of polymerization: The basicity is higher than that of ordinary polyaluminum chloride (PAC), second only to aluminum hydroxide.
●
Higher pH value: The aqueous solution is weakly acidic (pH 4-5), less acidic than ordinary polyaluminum. As hot areas usually have more acidic water, the treatment effect of ACH is better. Chlorinated aluminum hydroxide is more suitable for the markets in Southeast Asia and the Americas.
●
Broad-spectrum applicability: It can effectively coagulate within the pH range of 5-9.5, reducing the dependence of water treatment on pH value.
●
High-efficiency flocculation: Through electrochemical, adsorption, precipitation and other processes, it rapidly removes suspended solids, heavy metal ions (such as iron, cadmium, lead, mercury), organic matter and radioactive pollutants.
●
Low dosage: The unit treatment effect is 30% better than that of ordinary polyaluminum chloride, reducing the dosage of chemicals and the amount of sludge generated.

Industrial wastewater treatment: Used for decolorization of printing and dyeing wastewater, oil removal from papermaking wastewater, heavy metal removal from electroplating wastewater, etc.
●
Sludge reduction: Reduces sludge production by over 50%, lowering treatment costs.
2 Daily Chemicals and Personal Care
●
Antiperspirants and deodorants: Reduce sweat secretion by blocking sweat glands, inhibit bacterial growth, and are widely used in products such as roll-ons and sprays.
●
Cosmetic raw materials: Used in oil-control skin care products to regulate skin oil secretion.
3 Industrial Applications
●
Precision casting: Used as a mold coagulant and flame retardant.
●
Paper industry: Improve paper strength, whiteness, and smoothness, and reduce fiber loss.
●
Rubber and Tanning: As a crosslinking agent and dimensional stabilizer.
●
Petroleum and Chemical Industry: Used for oil well profile control, drilling fluid additives, etc.
4 Other Areas
●
Medicine: Ingredients of topical medications for treating hyperhidrosis.
●
Graphite products: Enhance fire resistance and physical and chemical properties.
Packaging and Storage
●
Liquid form (optional): 200L plastic drum / 1000L IBC tote / liquid bag.
●
Storage Conditions: Store in a cool, dry place away from direct sunlight; the liquid has a shelf life of 1 year (when sealed) and does not hydrolyze over a long period of time.
Frequently Asked Questions
Q
What is Aluminum Chlorohydrate (ACH) and how does it differ from ordinary Polyaluminum Chloride (PAC)?
Aluminum Chlorohydrate (ACH) is a high-basicity aluminum salt with a basicity higher than ordinary PAC, second only to aluminum hydroxide. Its aqueous solution is weakly acidic (pH 4–5), making it less corrosive and more effective in treating acidic water sources commonly found in tropical regions such as Southeast Asia and the Americas.
Q
What pH range is ACH effective for water treatment?
ACH can effectively coagulate and flocculate within a broad pH range of 5 to 9.5, significantly reducing the dependence of water treatment processes on strict pH control compared to conventional coagulants.
Q
How does ACH help reduce sludge and chemical dosage in water treatment?
Due to its high-efficiency flocculation mechanism — combining electrochemical, adsorption, and precipitation processes — ACH achieves a unit treatment effect approximately 30% better than ordinary PAC. This means less chemical is needed per treatment cycle, and sludge production is reduced by over 50%, significantly lowering overall treatment costs.
Q
Is ACH safe to use in antiperspirant and personal care products?
Yes. ACH is widely used as an active ingredient in antiperspirants and deodorants. It works by temporarily blocking sweat glands to reduce perspiration and inhibit bacterial growth. It is also used in oil-control cosmetic formulations to regulate skin oil secretion, and is a well-established ingredient in personal care industry applications.
Q
What are the available packaging options and how should ACH be stored?
ACH in liquid form is available in 200L plastic drums, 1000L IBC totes, or flexible liquid bags for bulk shipment. It should be stored in a cool, dry location away from direct sunlight. When properly sealed, the liquid product has a shelf life of 1 year and remains stable without hydrolysis over extended storage periods.
Q
What industries can benefit from using Aluminum Chlorohydrate (ACH)?
ACH has broad industrial applicability. Beyond water treatment (drinking water and industrial wastewater), it is used in the paper industry to improve strength and whiteness, in precision casting as a mold coagulant, in rubber and leather tanning as a crosslinking agent, in petroleum and chemical industries for drilling fluid additives, in medicine as a topical treatment for hyperhidrosis, and in graphite products to enhance fire resistance.
