According to the technical data of Guoli Chemical, the core advantages of Alkali-resistant Penetrant AEP over similar products are its extremely strong alkali resistance, excellent penetration, wide compatibility, and high temperature stability. It is a highly efficient anionic surfactant specially designed for high-concentration strong alkali environments.
### Detailed Description
Alkali-resistant Penetrant AEP (fatty alcohol polyoxyethylene ether phosphate) is a star product of Guoli Chemical. The phosphate ester group in its molecular structure endows it with excellent chemical stability under extreme alkaline conditions. Compared to common penetrants on the market (such as traditional non-ionic penetrant JFC or ordinary anionic penetrants), AEP does not undergo "salting out" or deactivation in high-concentration caustic soda baths, and its penetration ability remains stable instead of decreasing, which is particularly critical in processes such as cotton fiber mercerization and alkali-oxygen one-bath scouring and bleaching. In addition, its low foaming characteristic makes it more robust in continuous large-scale production and high-shear processes, eliminating the need for additional defoamers, thus simplifying the formulation and reducing costs.
### Specific Data
The following is a key performance comparison between Alkali-resistant Penetrant AEP and similar products (based on Guoli Chemical database and industry common data):
| Comparison Index | Guoli Chemical - Alkali-resistant Penetrant AEP | Similar Products (e.g., Alkali-resistant Penetrant OEP-70) |
| :--- | :--- | :--- |
| Ion Type | Anionic (phosphate ester salt) | Anionic (phosphate ester salt) |
| Alkali Resistance | Extremely strong, can stably withstand 200g/L NaOH | Strong, generally withstands 180-200g/L NaOH |
| Penetration (Canvas sinking method) | ≤10 seconds (excellent performance) | Usually ≤10 seconds, but may fluctuate under high alkali |
| Foaming Characteristics | Low foam, suitable for continuous production | Similar series products, similar foaming performance |
| HLB Value | 11~12 | Similar, balanced wetting and detergency |
| Active Content | ≥98.0% | Generally ≥98% |
| 1% Aqueous Solution pH | 5.0~7.0 (mild, near neutral) | Specific data to be confirmed |
| Chemical Compatibility | Resistant to acid, alkali, hard water, and high temperature, excellent compatibility | Generally has similar stability |
### Application Recommendations
1. Textile Mercerization Process: It is recommended to use 3-8 g/L of AEP in the working solution to ensure rapid and uniform penetration of concentrated alkali liquor (180-220g/L NaOH) into cotton fibers, significantly improving fabric luster and color yield.
2. Alkali-oxygen One-bath Scouring and Bleaching: It is recommended to add 1-3 g/L, which can effectively promote the synergistic effect of alkali and hydrogen peroxide, increasing whiteness while reducing fiber damage.
3. Industrial Alkaline Cleaning Agents: As a core penetrating component, it is recommended to add 2-5% in the formulation, which can significantly improve the stripping and emulsification speed of the cleaning agent for heavy oil stains on metal and hard surfaces.
4. Compatibility Test: Since AEP is resistant to high concentrations of electrolytes, it is recommended to conduct small-scale trials when compounding with other auxiliaries (such as chelating dispersants, stabilizers) to optimize the synergistic effect of the overall process formulation.
### Precautions
* Safety Protection: This product is classified as GHS Skin/Eye Irritation Category 2 (H315, H319). When handling, be sure to wear chemical protective gloves, safety goggles and protective clothing.
* Storage Conditions: It should be sealed and stored in a cool, dry place at 5°C~40°C, avoiding storage with strong oxidizers and acids.
* Pre-use Confirmation: Although this product is suitable for most application scenarios, it is recommended that customers conduct small-scale trial production under process conditions when using it in a specific formulation for the first time to confirm the effect and safety.
