1. Basic Information
- CAS Number: 32612-48-9
- Chemical Formula: RO(CH2CH2O)nSO3NH4 (where R=C12 alkyl group, n=2−3 ethylene oxide units)
- Synonyms: Ammonium lauryl ether sulfate; Laureth ammonium sulfate; Dodecyl polyglycol ether sulfate ammonium salt
2. Appearance and Properties
Typically a translucent gel-like paste or pale yellow liquid.
3. Physical and Chemical Properties
- Active Matter Content: Generally 68–72% (the core indicator for measuring product effectiveness).
- pH Value: 5.5–7.0 (for 2% aqueous solution at 25°C), presenting a weakly acidic to neutral range that is compatible with human skin pH.
- Solubility: Easily soluble in water; forms a stable, uniform solution without stratification or precipitation.
- Other Properties:
- Flash point: 110°C (ensures safety during storage and transportation).
- Functional performance: Possesses excellent wetting, detergency, foaming, and emulsifying capabilities.
- Biodegradability: Highly biodegradable, meeting environmental protection requirements for surfactants.
4. Applications
Primarily used in liquid cleaning and cosmetic products, with core functions focused on foaming and cleansing:
- Personal Care Products: Key raw material for shampoos, body washes, facial cleansers, and hand soaps. It produces rich, fine foam, delivers strong dirt-removing power, and has moderate degreasing ability—avoiding over-drying of hair or skin. Additionally, it enhances hair combability and leaves a comfortable, non-tight feeling on the skin after use.
5. Packaging Forms
Available in multiple specifications to meet different usage scenarios:
- Small-scale (sample/R&D use): 1kg plastic bottles.
- Medium-scale (small-batch production): 25kg plastic buckets (with airtight lids to prevent contamination).
- Large-scale (industrial mass production): 200kg heavy-duty plastic drums (suitable for palletized transportation and bulk storage).
6. Safety
- Risk Level: Relatively low safety risk, rated 1–3 (on a common 1–5 safety risk scale, where 1 is the lowest).
- Acne-Causing Risk: None, making it suitable for formulations targeting acne-prone skin.
- Irritation: Compared to Ammonium Lauryl Sulfate (ALS, a non-ethoxylated counterpart), ALES has significantly lower skin and eye irritation due to the introduction of ethylene oxide chains—making it more compatible with sensitive skin and gentle personal care products.
