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
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-polymerization aluminum-based 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 corrosive and more effective in acidic water environments such as those found in Southeast Asia and the Americas. ACH also delivers approximately 30% better unit treatment performance compared to standard PAC, requiring lower dosages and generating less sludge.
Q
What pH range is ACH effective in for water treatment?
ACH can effectively coagulate and flocculate contaminants within a broad pH range of 5 to 9.5. This broad-spectrum applicability significantly reduces the need for pH adjustment during water treatment processes, simplifying operations and lowering overall treatment costs.
Q
What types of contaminants can ACH remove from water?
ACH is highly effective at removing a wide range of contaminants through electrochemical, adsorption, and precipitation processes. These include suspended solids, turbidity, TOC (total organic carbon), iron, fluoride, and heavy metal ions such as cadmium, lead, and mercury. It is also effective against organic matter and radioactive pollutants, making it suitable for both drinking water purification and industrial wastewater treatment.
Q
Is Aluminum Chlorohydrate safe for use in 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 sweat secretion and inhibiting bacterial growth. It is also used in cosmetic raw materials, particularly in oil-control skin care products to regulate skin oil secretion. ACH is also an ingredient in topical medications for treating hyperhidrosis (excessive sweating).
Q
What are the available packaging options for ACH liquid?
ACH liquid is available in multiple packaging formats to suit different logistics and usage needs: 200L plastic drums, 1000L IBC totes, and flexible container liquid bags. These options allow for convenient handling, bulk shipping, and storage flexibility for both small-scale and large-scale industrial customers.
Q
What are the recommended storage conditions for ACH liquid?
ACH liquid should be stored in a cool, dry place away from direct sunlight and heat sources. When properly sealed, the liquid product has a shelf life of 1 year and does not undergo hydrolysis over a long period of time. Proper storage ensures the product maintains its chemical stability and treatment effectiveness throughout its shelf life.
