Question 4

Does the alkali-resistant penetrant AEP meet environmental requirements? Can a test report be provided?

Accepted Answer

The alkali-resistant penetrant AEP belongs to the common chemical environmental classification level, with a clear aquatic ecotoxicity label (H402). It is not a "green and pollution-free" type of environmental product, but its environmental risk is controllable. Through proper wastewater disposal, it can meet general industrial environmental compliance requirements. Detailed Explanation The alkali-resistant penetrant AEP (CAS No.: 68439-39-4), in terms of environmental compliance, is classified as Hazardous to the aquatic environment - Acute hazard category 3 according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and the Safety Data Sheet (SDS). Its hazard statement includes H402 (Harmful to aquatic life), meaning that if the product is discharged directly into water bodies without treatment, it may cause harm to aquatic ecosystems. However, it should be noted that this classification is very common among industrial surctants, and it does not mean the product is banned or highly toxic. The key lies in proper wastewater treatment after use. From a regulatory compliance perspective, as a phosphate ester anionic surctant, the alkali-resistant penetrant AEP contains phosphorus in its molecular structure. The product itself may produce toxic or irritating fumes such as carbon monoxide and carbon dioxide during high-temperature or combustion decomposition, but it is not flammable or explosive and is not classified as dangerous goods. To determine whether it meets specific environmental standards (such as OEKO-TEX, ZDHC, Bluesign, etc. for the textile industry), the actual end-use and the customer's specific certification requirements must be considered. Regarding the test report, Guoli Chemical provides a routine Certificate of Analysis (COA) for the alkali-resistant penetrant AEP, covering key technical indicators such as active content (≥98.0%), pH value (1% aqueous solution 5.0~7.0), acid value (150~180 mgKOH/g), and free phosphoric acid (≤5.0%). However, for specific third-party environmental test reports, such as biodegradability testing (OECD 301 series), SGS hazardous substance screening reports, or RoHS/REACH compliance declarations, there are no ready-to-download electronic documents in the company database. Please contact the Guoli Chemical sales and technical team to obtain them separately based on purchase requirements.

Question 8

How to use alkali-resistant penetrant AEP? What is the recommended dosage?

Accepted Answer

The specific usage and dosage of alkali-resistant penetrant AEP should be determined through experiments based on the application field and process conditions. The general recommended dosage range is 0.5%~2.0% of the total working fluid volume. Detailed Description Alkali-resistant penetrant AEP (tty alcohol polyoxyethylene ether phosphate) is an anionic surctant that is easily soluble in water. In practical use, it can be directly mixed uniformly with cold or warm water and then added to the working fluid system. With its excellent chemical stability, this product is especially suitable for high-concentration alkali bath environments. It can maintain excellent penetration and wetting properties even under conditions of up to 200g/L sodium hydroxide, which is not achievable by most ordinary penetrants. To ensure its full efficacy, it is recommended to pre-mix AEP with a measured amount of water into a uniform liquid, and then slowly add it to the main working fluid under stirring. When preparing alkaline working fluids, the usual dosing sequence is: first add auxiliaries like AEP to water, mix thoroughly, and then add solid caustic soda. This takes advantage of AEP's dispersibility and avoids direct contact with high-concentration alkali liquor, which could cause local performance issues due to heat generation. In processes requiring long standing times like cold pad-batch, its low-foaming property and sustained penetration ability ensure uniform coverage and deep wetting of the treatment liquid on the bric. The optimal dosage is comprehensively influenced by ctors such as the substrate being treated (cotton, blends, leather, metal), bath ratio, alkali concentration, temperature, and treatment time. The database does not provide a fixed absolute dosage. Therefore, we strongly recommend conducting small-scale trials based on your specific process conditions before use to balance cost and treatment effect and determine the most economical dosage for your production flow. Technical Parameters The following are key physicochemical indicators of alkali-resistant penetrant AEP for reference in formulation design (Data source: Guoli Chemical Product Database): ItemParameter AppearanceColorless to light yellow transparent liquid Active Content≥98.0% Ionic TypeAnionic pH (1% Aqueous Solution)5.0~7.0 HLB Value11~12 Penetrating Power (Standard Canvas Sinking Method)≤10 seconds Alkali Resistance StabilityCan withstand 200g/L NaOH Foaming PropertyLow foam Surce Tension (1% Aqueous Solution)30~35 mN/m Note: The database currently does not have fixed recommended dosage parameters for specific application scenarios. The actual dosage should be determined by user trials. Application Suggestions Based on the application fields recorded in the Guoli Chemical Database, we provide the following reference dosage ranges and process suggestions for your testing and verification: Textile Dyeing and Finishing Field One-bath scouring and bleaching of cotton bric with alkali and peroxide: Recommended test dosage is 0.5%~1.5% of the working fluid. Adding AEP to the bath containing caustic soda and hydrogen peroxide can significantly improve whiteness and capillary effect. Cold pad-batch pretreatment: Recommended test dosage is 0.5%~2.0% of the working fluid. Its excellent low-temperature and long-time penetrability ensures that the bric is fully and uniformly impregnated with the treatment liquid during storage. Desizing and mercerizing processes: Recommended test dosage is 0.5~3.0g/L. Adding to the concentrated caustic soda bath in mercerizing promotes rapid penetration of alkali into the fiber interior, improving mercerizing uniformity and luster. Other Industrial Fields Leather soaking and degreasing: Recommended test dosage is 0.3%~1.0% of the raw hide weight. When used together with alkaline auxiliaries like soda ash, it accelerates the softening of dry hides and the emulsification and removal of natural ts. Paper pulping and penetration: Recommended test dosage is 0.5%~1.5% of the absolute dry raw material. Adding to the cooking liquor helps alkali liquor quickly wet the interior of wood chips or grass raw materials, improving pulp yield. Alkaline cleaning of metals and hard surces: Recommended test addition is 2.0%~5.0% in the concentrated cleaning agent formulation. It effectively enhances the cleaning liquid's ability to penetrate and strip heavy oil and dirt from metal surces. The above ranges are general estimates based on product characteristics, not fixed standards. The final dosage must be determined through systematic experiments based on your specific raw materials, equipment, and water quality conditions.

Question 10

What are the physicochemical technical parameters of alkali-resistant penetrant AEP?

Accepted Answer

Alkali-resistant penetrant AEP is an excellent anionic surctant that maintains high efficiency in wetting and penetration even under strong alkaline conditions of 200g/L NaOH, with an HLB value of approximately 11~12, and its overall performance r exceeds conventional penetrants. Detailed Description Alkali-resistant penetrant AEP (tty alcohol polyoxyethylene ether phosphate ester) appears as a colorless to light yellow transparent liquid with a molecular weight of 700~900. This product is easily soluble in water at room temperature, with a density between 1.05~1.10 g/cm³ and a kinematic viscosity of approximately 200~500 mPa·s. It is an anionic surctant with high surce activity; the surce tension of a 1% aqueous solution is 30~35 mN/m, and the critical micelle concentration (CMC) is only 0.01~0.05 g/L, meaning it can effectively reduce the surce tension of the system at very low dosage. In terms of chemical stability, AEP performs exceptionally well. It can withstand up to 200g/L sodium hydroxide solution, does not decompose or produce oil slick under high-temperature boiling conditions, and can also tolerate certain concentrations of acidic environments and high-hardness water. Its low-foaming characteristic means it does not cause operational issues due to foam accumulation in various industrial cleaning and circulating systems. The total active substance content of AEP is ≥98.0%, moisture content ≤1.0%, and free phosphoric acid content is controlled at ≤5.0%, ensuring product purity and safety in use.

The actual dosage should be determined through compatibility tests based on the alkali concentration of the working solution, treatment temperature, and substrate conditions to achieve optimal process effectiveness and economy. Precautions During operation, wear chemical protective gloves, protective clothing, and safety goggles to avoid direct skin contact. If contact occurs, rinse immediately with plenty of water and soap. Store in a cool, dry place at 5°C~40°C, keep the container tightly sealed, and avoid storing together with strong acids and strong oxidizers. The product is of low-foaming type, but when mixed with large amounts of high-foaming additives, the foam characteristics of the system may change; compatibility evaluation should be conducted during formulation design.
