Aluminum Chlorohydrate
1. Basic Product Information
Product Name: Aluminum Chlorohydrate
CAS Number: 1327-41-9
Molecular Formula: Al2(OH)5Cl
Molecular Weight: 210.48
Synonyms: Aluminum hydroxychloride, ACH, Basic aluminum chloride
Product Category: Cosmetic antiperspirant raw material, water treatment flocculant, industrial inorganic coagulant, personal care additive
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White or pale yellow crystalline powder / transparent viscous aqueous solution
- Odor: Slight mild acidic odor
- Solubility: Freely soluble in water and methanol; insoluble in ethanol, oil solvents and aliphatic hydrocarbons
- Melting Point: Decomposes upon heating without fixed melting point
- Density (20°C solid): 1.33–1.38 g/cm3
- Hygroscopicity: Strongly hygroscopic under high humidity environment
- Aqueous Stability: Stable under weak acidic and neutral aqueous conditions; precipitates aluminum hydroxide flocculent under strong alkaline environment
Chemical Characteristics
- Molecular Structure: Polynuclear hydroxy aluminum chloride inorganic polymer, basic aluminum chloride structure with hydroxyl bridging groups
- Core Functional Mechanism: High-efficiency cationic flocculant; coagulates suspended impurities in wastewater for purification; widely used in antiperspirants to block sweat gland pores by hydrolyzing into aluminum hydroxide precipitates on skin surface
- Photostability: Stable under normal sealed storage, no obvious light-induced degradation
- Thermal Stability: Stable below 80°C; heating above 120°C releases hydrogen chloride gas and decomposes into aluminum oxide
- Chemical Compatibility: Compatible with water-based cosmetic surfactants and inorganic water treatment reagents; incompatible with strong alkaline substances, phosphate and sulfate high-concentration solutions
3. Main Application Fields
- Core Application: Cosmetic Antiperspirant Raw Material
Main active ingredient for antiperspirant spray, roll-on deodorant and body care products to reduce perspiration secretion - Municipal & Industrial Water Treatment Flocculant
Coagulant for tap water purification, printing and dyeing wastewater, domestic sewage and industrial wastewater sedimentation treatment - Paper Making Auxiliary
Retention aid and sizing stabilizer in papermaking process to improve fiber retention rate - Textile Dyeing Auxiliary
Mordant for cotton and blended fabric dyeing to enhance color fastness - Cosmetic Preservative Auxiliary
Stabilizing additive in body care formulations to adjust system ion balance
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Inorganic Chemicals / Cosmetic & Water Treatment Additives
Reason: Polyhydroxy aluminum inorganic flocculant widely used in daily care and environmental protection water treatment industries
2) English Product Group Dropdown Options
Recommended Selection: Basic Inorganic Chemicals
Do NOT classify as pharmaceutical raw materials; it is industrial and daily chemical inorganic additive
3. Standard Foreign Trade Packaging Specification
1kg PE sealed plastic bottle for lab test samples; 25kg double PE lined plastic drum / woven bag for bulk industrial orders
