Detergent AR-812 is easy to use. It is recommended to dilute and use it at a dosage of 0.5~5 g/L (or 1%~5%) according to the specific application scenario. It is a highly efficient, low-foaming, and controllable nonionic surfactant.
Detailed Description
Detergent AR-812 (CAS No.: 9036-19-5) is a highly active nonionic surfactant produced by Guoli Chemical, with an effective content ≥97%, easily soluble in water, HLB value of 13.0, cloud point of 65~70°C (1% aqueous solution), and good penetration, emulsification, and dispersion capabilities. Users can directly add it into water and stir evenly for different application scenarios. The operation is simple. The product is a colorless to light yellow transparent viscous liquid at room temperature, with good low-temperature fluidity, easy to measure and add.
The critical micelle concentration (CMC) of this product is only 0.1~0.2 g/L (25°C), surface tension 27~29 mN/m (1% aqueous solution, 25°C), penetration force ≤10 seconds (standard canvas piece), showing excellent wetting and penetration performance. The foam characteristics are medium foam with moderate stability, not prone to excessive foam problems in industrial cleaning. It has strong alkali resistance, stable in dilute alkaline solutions, and can be widely used in textile printing and dyeing, metal processing, industrial cleaning, papermaking, and other fields.

Application Recommendations
Based on Guoli Chemical's product database and common industry practice, the following are recommended dosages for each application scenario:
Textile Printing and Dyeing Field
- Pretreatment scouring (after desizing/scouring/bleaching): Recommended dosage 1.0~3.0 g/L, bath ratio 1:10~1:20, temperature 40~60°C, treatment time 20~30 minutes, can efficiently remove residual sizing and impurities.
- Soaping after dyeing and printing (to remove unfixed dyes): Recommended dosage 1.0~2.0 g/L, bath ratio 1:10~1:30, temperature 60~80°C (adjust according to dye type), treatment 15~20 minutes, effectively remove unfixed dyes and improve color fastness.
- Scouring and deoiling of synthetic fibers: Recommended dosage 2.0~4.0 g/L, temperature 50~70°C, can quickly emulsify and remove spinning oils and weaving oils.
Industrial Cleaning Field
- Degreasing and removing oil from metal parts: Recommended to prepare a 2%~5% working solution, using immersion, ultrasonic, or spray method, temperature 40~60°C (heating can significantly improve cleaning efficiency), cleaning time adjusted according to oil level, generally 5~15 minutes.
- Heavy oil removal on hard surfaces: Recommended to prepare a 3%~5% working solution, combined with brushing or high-pressure rinsing. For stubborn oil stains, the concentration can be appropriately increased to 5%~8%.
Papermaking Industry
- Washing and maintenance of paper machine felts: Recommended dosage 0.5~2.0 g/L (continuous online washing) or 2.0~5.0 g/L (batch offline washing), temperature 40~60°C, can effectively dissolve resin, stickies, and filler deposits.
Note: The above recommended dosage data are industry common experience values. The specific dosage should be determined through trials based on actual working conditions (oil level, water hardness, equipment conditions, etc.). There is no official recommended dosage value for this product in the Guoli Chemical database. It is recommended that users take the results of small-scale tests as the standard.
Precautions
- Dissolution method: Slowly add AR-812 into stirred water to avoid agglomeration caused by one-time large addition. Warm water (30~40°C) dissolves faster, but the use temperature is recommended to be controlled below the cloud point (65~70°C) to ensure the best cleaning effect.
- Water adaptability: This product is resistant to hard water and has stable performance under hard water conditions. However, if the working solution hardness is too high (>300ppm), it is recommended to use with an appropriate amount of chelating dispersant.
- Safety protection: Although this product has no skin irritation (skin irritation index <0.5), it is still recommended to wear protective gloves and goggles during operation to avoid long-term repeated contact leading to skin degreasing and drying.
- Storage conditions: Recommended storage temperature 5~40°C, away from strong oxidizers and strong acids, keep containers sealed. Turbidity or solidification may occur at low temperatures. After warming to room temperature and stirring evenly, it can be restored for use without affecting product performance.
- Environmental compliance: This product is APEO-free, with biodegradability ≥90%, meeting international environmental regulations. Cleaning wastewater should be properly treated before discharge.
