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.

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.

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 greater than 80%, second only to aluminum hydroxide. Compared to ordinary PAC, ACH has a higher degree of polymerization, a less acidic aqueous solution (pH 4.0–4.4), and a 30% better unit treatment effect, resulting in lower chemical dosage and reduced sludge generation.
Q
Why is ACH particularly suitable for water treatment in Southeast Asia and the Americas?
Hot climate regions such as Southeast Asia and the Americas typically have more acidic source water. Since ACH's aqueous solution is only weakly acidic (pH 4–5) and can effectively coagulate within a broad pH range of 5–9.5, it performs better than ordinary PAC in these regions and reduces the need for pH adjustment during water treatment.
Q
What contaminants can ACH remove in water treatment applications?
ACH can remove a wide range of contaminants through electrochemical, adsorption, and precipitation processes. These include suspended solids, turbidity, TOC (total organic carbon), heavy metal ions such as iron, cadmium, lead, and mercury, fluoride, organic matter, and radioactive pollutants. It is effective for both drinking water purification and industrial wastewater treatment.
Q
How is ACH used in personal care and cosmetic products?
ACH is widely used as the active ingredient in antiperspirants and deodorants. It works by temporarily blocking sweat gland ducts to reduce sweat secretion and inhibit bacterial growth, making it suitable for roll-on and spray formulations. It is also used in oil-control skin care products to help regulate skin oil secretion.
Q
What packaging options are available for ACH, and how should it be stored?
ACH in liquid form is available in 200L plastic drums, 1000L IBC totes, and container liquid bags to suit various shipping and usage requirements. It should be stored in a cool, dry place away from direct sunlight. When sealed properly, the liquid product has a shelf life of 1 year and does not hydrolyze over a long period of time.
Q
What industrial applications can ACH be used for beyond water treatment?
Beyond water treatment, ACH has a wide range of industrial applications. It is used as a mold coagulant and flame retardant in precision casting, as a sizing agent in the paper industry to improve strength, whiteness, and smoothness, as a crosslinking agent in rubber and tanning, and as a drilling fluid additive in the petroleum and chemical industry. It is also used in medicine as an ingredient in topical treatments for hyperhidrosis, and in graphite products to enhance fire resistance.
