Aluminum Chlorohydrate as Coagulant for Removal of Total Organic Carbon and Pharmaceuticals

Kuc, Joanna, et al. Molecules, 2022, 27(17), 5740.

Chemical coagulation is one of the methods used to remove organic contaminants, such as pharmaceuticals, from water. Aluminum chlorohydrate (ACH) has many advantages as an inorganic coagulant, such as wide application and low cost. In addition to being used to coagulate river water and textile wastewater, aluminum chlorohydrate has also been explored for coagulation to remove erythromycin (ERY), fluoxetine (FLX), amoxicillin (AMO), colistin (COL), ethinyl estradiol (EE), and diclofenac (DIC).
The coagulation effect of aluminum chlorohydrate
· The use of aluminum chloride hydrate in drug coagulation significantly reduced the concentration of total organic carbon (TOC), ERY, FLX, AMO, COL, EE, and DIC by 88.7%, 36.4%, 24.7%, 29.0%, 25.5%, 35.4%, and 30.4% respectively, in ideal conditions for coagulation of contaminated surface water.
· Furthermore, the turbidity, color, TSS, Total N, and N-NH4 were decreased by 96.2%, more than 98.0%, 97.8%, 70.0%, 88.7%, and 37.5% respectively.

Effects of Aluminum Chlorohydrate on Estrogen Signaling in Breast Cancer Cells

Gorgogietas, Vyron A., et al. Journal of molecular biochemistry, 2018, 7(1), 1-3.

Aluminum chlorohydrate (ACH) is an active antiperspirant widely used in cosmetics and is often applied to the underarms, which exposes the area close to the human breast to high and sustained exposure to aluminum. The mechanism of action of aluminum chlorohydrate as a metallic estrogen and its potential impact in the development of estrogen receptor-associated breast cancer were investigated.
Interference mechanism of aluminum chlorohydrate
· Aluminum chlorohydrate induces a significant increase in estrogen receptor protein levels by interfering with estrogen receptor gene expression or estrogen receptor protein stability.
· Influence estrogen receptor-mediated gene expression, including p53, cyclin D1, and c-fos genes, through direct or indirect estrogen receptor DNA binding.
· Aluminum chlorohydrate may affect the physiology and function of mitochondria by inducing the perinuclear localization of estrogen receptors, thereby providing necessary energy production and supply of precursor molecules to cancer cells.

Aluminum Chloride Hydroxide Used to Prepare Low-Cost Alumina Nanofibers

Milanović, Predrag, et al. Ceramics International, 2013, 39(2), 2131-2134.

Aluminum chloride hydroxide/polyvinyl alcohol/water precursors were used to prepare nanoalumina fibers using electrospinning technology. The fibers can be used as reinforcement materials for various high-performance composite materials.
Preparation procedures of alumina nanofibers
· Alumina nanofibers were prepared by first preparing a 10% mass aqueous solution of polymer, to which aluminum chloride hydroxide was added in a 5:1 mass ratio. The solution was then stirred for 1 hour at 30°C until air bubbles disappeared after 24 hours. The solution was then used within 2-3 days of preparation.
· The solution was loaded into a 20 ml plastic syringe with a 0.8 mm needle orifice, and fed into an Electrospinner CH-01 apparatus at a mass flow rate of 1 ml/h. A high-voltage supply capable of producing 30 kV was applied, with voltage varying from 20 kV to 28 kV and mass flow from 0.5 to 3 ml/h.
· The stable process was achieved at 28 kV and 0.5 ml/h flow rate. The electrospinning process was conducted in air at an ambient temperature of 21°C and relative humidity of 40-60%. A fixed distance of 15 cm between the needle and collector was maintained, with aluminum foil and filter paper used for fiber collection. The collected fibers were then heat treated at 1100°C for 1 hour in air to obtain alumina nanofibers.

Comparison of the Effectiveness of Aluminum Chlorohydrate as a Chemical Flocculant in Wastewater Treatment

Khaya Pearlman Shabangu, et al. Water, 2022, 14(16), 2495.

This work evaluated the effectiveness of two chemical flocculants including aluminum chlorohydrate and polyamine in removing the content of bulk inert pollutants such as particulate chemical oxygen demand (COD) and turbidity in wastewater treatment.
Evaluation methods and results
· The goal of this research was to evaluate the effectiveness of using alum-chlorohydrate (1%) compared to polyamine (1%) chemical coagulants in a lab-scale flocculator or jar test method for treating brewery wastewater. The objective was to achieve zero liquid effluent discharge by removing turbidity and particulate COD (inert or non-biodegradable COD). Specifically, the study aimed to analyze the impact of combining aluminium chlorohydrate 1% with polyamine 1% to create PAC.
· The findings indicated that utilizing various dosages of polyamine along with 50% aluminium chlorohydrate as combined coagulants led to enhanced removal efficiencies of particulate chemical oxygen demand, color, and turbidity. When using the combination treatment of polyamine-aluminium chlorohydrate (PAC), a turbidity removal efficiency of 90.50% and particulate chemical oxygen demand removal of 59.36% were achieved. This was compared to using polyamine alone, which resulted in a particulate chemical oxygen demand removal of 50% and turbidity removal of 75%. Similarly, the use of aluminium chlorohydrate alone showed removal efficiencies of 37% for particulate chemical oxygen demand and 54% for turbidity.

What is aluminum chlorohydrate?

Aluminum chlorohydrate is a solid substance that is commonly used in personal cleanliness products such as antiperspirants and deodorants.

How does aluminum chlorohydrate function as an antiperspirant agent?

Aluminum chlorohydrate temporarily blocks sweat glands, reducing perspiration and odor. It forms a gel-like plug in the sweat ducts, preventing sweat from reaching the skin's surface.

What is the chemical formula of aluminum chlorohydrate?

The chemical formula of aluminum chlorohydrate is Al2ClH9O7.

Why is aluminum chlorohydrate used in cosmetics?

Aluminum chlorohydrate is used in cosmetics, particularly antiperspirants and deodorants, to reduce the production of perspiration, eliminate unpleasant odor, and protect against the formation of odors on the skin.

Has the safety of aluminum chlorohydrate been reviewed by regulatory bodies?

Yes, the Food and Drug Administration has reviewed the safety of aluminum chlorohydrate complexes and approved their use in over-the-counter (OTC) antiperspirant drug products.

Can aluminum chlorohydrate be used in cosmetics and personal care products marketed in Europe?

Yes, under the general provisions of the cosmetics regulation of the European Union, aluminum chlorohydrate complexes may be used in cosmetics and personal care products.

What are some other uses of aluminum chlorohydrate?

Apart from its use in cosmetics, aluminum chlorohydrate is also used as a flocculant in water purification.

Is aluminum chlorohydrate safe for use in cosmetics and skincare products?

Aluminum chlorohydrate is considered safe for use in cosmetics and skincare products. However, individual sensitivities or allergies may occur, so patch testing is recommended, and users should discontinue use if any adverse reactions are experienced.
