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.

Application Area
(1) Water Treatment
Drinking water purification: As a flocculant, it removes impurities such as turbidity, TOC (total organic carbon), iron, fluoride, cadmium, etc.
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

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 coagulant with a basicity higher than ordinary PAC, second only to aluminum hydroxide. Its aqueous solution is weakly acidic (pH 4–5), making it less aggressive than standard PAC. ACH offers superior flocculation efficiency and is particularly effective in slightly acidic water conditions common 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. This broad-spectrum applicability significantly reduces the dependence of water treatment processes on strict pH adjustment, making it more versatile and cost-effective compared to many alternative coagulants.
Q
What types of pollutants can ACH remove during water treatment?
ACH is highly effective at removing a wide range of pollutants, including suspended solids, turbidity, total organic carbon (TOC), heavy metal ions (such as iron, cadmium, lead, and mercury), fluoride, organic matter, and radioactive pollutants. It is suitable for both drinking water purification and industrial wastewater treatment applications.
Q
How does ACH compare to ordinary PAC in terms of dosage and sludge generation?
ACH delivers approximately 30% better unit treatment efficiency compared to ordinary polyaluminum chloride. This means a lower dosage is required to achieve the same treatment result, which directly reduces chemical consumption costs. Additionally, ACH reduces sludge production by over 50%, significantly lowering sludge handling and disposal expenses.
Q
Is ACH safe for use in antiperspirants and personal care products?
Yes, ACH is widely used as an active ingredient in antiperspirant and deodorant products such as roll-ons and sprays. It works by temporarily blocking sweat glands to reduce perspiration and inhibiting bacterial growth that causes odor. It is also used in oil-control cosmetic formulations to help regulate skin sebum secretion.
Q
What are the recommended packaging options and storage conditions for ACH liquid?
ACH liquid is available in 200L plastic drums, 1000L IBC totes, and flexible liquid bags for bulk transport. It should be stored in a cool, dry location away from direct sunlight. When kept in sealed containers, the liquid form has a shelf life of 1 year and does not undergo hydrolysis over extended storage periods.
