Frequently Asked Questions (FAQ)

Q1: What is “Aluminum diacetate hydroxide CAS 142-03-0”?

A: It is a basic aluminum acetate salt — a white powder with the formula C₄H₇AlO₅ (Al(OH)(CH₃COO)₂) and a molecular weight of 162.08. CAS 142-03-0 is its unique registry number, which identifies the substance unambiguously worldwide. 

Q2:What are its physical and chemical properties?

A: It is White powder, essentially odorless, weakly acidic (pH approx. 4–5 as a 2% slurry). The freshly prepared hydrated form is soluble in water; the dried product is insoluble in water but soluble in inorganic acids. Decomposes upon heating or exposure to moisture; incompatible with strong oxidizing agents.

Q3: What are its main applications?

A: It is widely used in pharmaceuticals & personal care, Textile & printing, water treatment and other fields. 

Q4: How should it be stored and transported?

A: Store sealed in a cool, dry place under inert atmosphere; protect from moisture; keep away from strong oxidizing agents. It is generally shipped as non-dangerous goods.

Q5: What to do in case of spillage or contact?

Spillage: sweep up and place into a closed container; do not flush into drains or waterways.
Contact: eyes — rinse thoroughly with water;
                skin — wash with soap and water;
                inhalation — move to fresh air;
                ingestion — rinse mouth and seek medical attention.

Application 1: What are its most typical applications?

Its two classic uses are as an astringent/antiseptic in topical medicine and as a mordant in textile dyeing; it is also used in antiperspirants, phosphorus-removal water treatment and high-purity alumina production.

Application 2: What are its specific uses in the pharmaceutical and cosmetics fields?

Leveraging its astringent and antiseptic properties, it is used in antiperspirants, skin astringents, disinfectants, and ointments for treating poison ivy / poison oak dermatitis. Its mechanism of action involves releasing aluminum ions that cross-link and precipitate epidermal proteins, forming a protective layer and reducing exudation. It is also used as a component of embalming fluids.

Application 3: What role does it play in textile dyeing and printing?

It is mainly used as a mordant to help dyes fix onto fabric fibers; it can also serve as a flame retardant and waterproofing agent in textile treatment. Compared with neutral aluminum acetate, basic aluminum acetate offers better hydrolysis stability, making its mordanting effect more controllable.

Application 4: How it is used in environmental water treatment?

It is used as a coagulant/flocculant for phosphorus removal — aluminum-salt flocculation precipitates phosphate and effectively lowers its concentration in industrial and municipal wastewater.

Storage:

  • Keep sealed, dry and cool under an inert atmosphere (e.g., nitrogen); room temperature is acceptable;
  • Strictly protect from moisture — it hydrolyzes upon contact with water vapor (the dried product is insoluble in water and its properties change once moistened);
  • Keep away from strong oxidizing agents; maintain package integrity;
  • Keep away from heat sources and prolonged high-temperature exposure.

Transportation Conditions:

  • Classified as non-hazardous general chemical.
  • Use sealed, moisture-proof, damage-resistant packaging (bags or drums depending on quantity);
  • Do not ship together with strong oxidizing agents; avoid rain and high-temperature exposure;
