According to Guoli Chemical technical data, MOA-12 (AEO-12) exhibits outstanding comprehensive performance advantages among similar fatty alcohol polyoxyethylene ethers, mainly reflected in excellent emulsifying, wetting, and detergency three-in-one effects, as well as superior application stability and environmental safety.
In detail, as Guoli Chemical's flagship nonionic surfactant, the advantages of MOA-12 (lauryl alcohol polyoxyethylene ether-12, C12-14 alcohol + 12EO) can be summarized as follows:
1. **Strong emulsifying ability**: HLB value of approximately 14.5, which falls within the efficient range of oil/water (O/W) emulsifiers. It can significantly reduce oil/water interfacial tension, forming stable and fine emulsions, especially excelling in fields such as pesticide emulsions, cosmetic emulsification and solubilization, and metal cleaning emulsification and degreasing.
2. **Outstanding wetting and permeability**: The penetration force of a 0.1% aqueous solution is > 300 seconds (canvas settling method), with surface tension as low as 28~32 mN/m. This means it can rapidly spread and penetrate surfaces of textiles, leather, metals, etc., accelerating the efficiency of subsequent processes (such as scouring, degreasing).
3. **Reliable detergency**: It has good emulsifying dispersion and removal ability for various oil stains (mineral oils, natural fats, floating colors, etc.), demonstrating stable decontamination performance in textile soaping, household washing, and industrial hard surface cleaning.
4. **Excellent chemical and water stability**: It maintains structural stability in acidic and alkaline media, and has excellent tolerance to calcium and magnesium ions in hard water, without easily forming precipitates, ensuring stable performance under complex water quality and different process conditions (such as high-temperature scouring, alkaline degreasing).
5. **Low toxicity, safe, and environmentally friendly**: The product itself is low-toxic (rat oral LD50 > 2000 mg/kg), non-irritating to the skin, non-sensitizing, and only causes mild reversible irritation to the eyes. More importantly, it is readily biodegradable (OECD 301 method, > 60% degradation in 28 days) with low bioaccumulation potential, complying with current international environmental regulations and green chemical trends, thereby reducing ecological accumulation risks after use.
6. **Stable physical form, easy to handle**: It appears as a white to slightly yellow paste or waxy solid at room temperature, with active ingredient content ≥ 99%, low free alcohol content, not prone to stratification, facilitating precise metering and stable feeding at different temperatures.
Compared to similar products with low EO numbers (such as MOA-3, MOA-7) or high EO numbers (MOA-15, MOA-23), the EO number (12) of MOA-12 reaches a "sweet spot" in the hydrophilic-lipophilic balance, offering both good water solubility (cloud point up to 90~95°C) and strong emulsifying power for oils, along with moderate foam that is easy to rinse, meeting current industrial needs for energy and water conservation. Specific technical parameter comparisons are as follows (taking Guoli Chemical database indicators as examples):
| Key Indicator | MOA-12 (AEO-12) | Characteristics of Similar Low-EO Products | Characteristics of Similar High-EO Products |
| :--- | :--- | :--- | :--- |
| **EO Number** | 12 | Usually 3~7 | Usually 15~25 |
| **HLB Value** | 14.5 (Hydrophilic) | 8~12 (Lipophilic to moderate) | 15~17 (Strongly hydrophilic) |
| **Penetration (0.1%, canvas settling)** | > 300 seconds (Good) | General (mainly oil-soluble) | Slightly weak (thick hydration layer, slower spreading) |
| **Emulsifying Power** | Excellent (O/W emulsion) | Weak (suitable for W/O or lipophilic emulsification) | Good (but for heavy oil emulsification, may not match 12EO) |
| **Cloud Point (1% aqueous solution)** | 90~95°C | Usually < 50°C, limited low-temperature use | > 100°C, suitable for higher temperatures but may increase foam |
| **Foam Characteristics** | Moderate, easy to rinse | Low to no foam | Higher, requires more rinse water |
| **Application Focus** | General purpose scouring, cleaning, emulsification, degreasing | Mainly as water-in-oil emulsifier, synthesis of lipophilic intermediates | High-temperature dispersant, leveling agent, high cloud point cleaner |
In summary, Guoli Chemical's MOA-12 (AEO-12), with its balanced emulsifying-wetting-detergency capabilities, wide temperature range applicability, excellent hard water/acid-base resistance stability, and outstanding environmental safety features, has become the preferred choice for formulation upgrades and green transformation in multiple industries such as textiles, daily chemicals, leather, pesticides, and industrial cleaning.
