Broad spectrum compatibility

Perfectly compatible with anionic, nonionic, and amphoteric surfactants

Strong cleaning power

Quickly emulsify grease and suspend dirt, with a cleaning efficiency 15-20% better than similar products

Low impurities, high purity

Reduce formula odor and delamination risk, ensure transparent appearance of end products, and reduce irritation

Concentrated laundry detergent

Core Value: Adding 8-10% can replace 18-20% of conventional SLES by 30%, reducing the cost of raw materials by 35% per ton

Application Details: Suitable for “cold water instant” formula, compatible with proteases and cellulases, without affecting activity

Data Highlights: After 20 times dilution, the decontamination power is still 15% better than the national standard, and the stability of foam reaches 90%

Concentrated tableware cleaner

Core Value: High activity substances enhance the emulsifying power of oil stains, with an addition amount of 6-8% to adapt to heavy oil pollution concentration formulas

Application Details: It is recommended to mix with coconut oil diethanolamide (ratio: 10:1) to improve the durability of foam

Data Highlight: The removal rate of heavy oil stains (animal fats) in the kitchen has reached 98%, and it is still effective after diluting 15 times

Concentrated shampoo/shower gel

Core Value: Adding 5-7% instead of conventional 10-12%, more streamlined formula, suitable for travel/small capacity packaging

Application Details: Compound 0.5% panthenol can further reduce irritation, and pH control at 6.5-7.5 is milder

Data Highlight: Foam volume reaches 300ml/10g, 20% better than competing products of the same concentration

Mechanical Parts Cleaning Agent

Core Value: Stable in strong alkaline systems with pH 10-12, quickly emulsify cutting oil with 0.5-1% addition

Application Details: Suitable for ultrasonic cleaning, combined with EDTA (chelating agent) to enhance the protection of metal surfaces

Data Highlights: Stored in a strong alkaline environment at 80 ℃ for 30 days, with an activity retention rate of 96% and an oil emulsification rate of 0.8g/min

Textile Pre-treatment Additives

Core Value: 0.3-0.5% addition to achieve efficient wetting and reduce water consumption in dyeing and finishing processes by 30%

Application Details: In the treatment of cotton/synthetic blended fabrics, it can replace traditional alkylbenzene sulfonate and reduce the risk of fabric yellowing

Leather Degreaser

Core Value: Efficiently remove surface oil from leather in alkaline degreasing solution (pH 9-10), improving subsequent tanning effects

Application Details: It is recommended to compound with alkylphenol polyoxyethylene ether (ratio 3:1) to enhance the uniformity of degreasing

Concentrated shower gel/facial cleanser

Core Value: Adding 4-6% can achieve a regular cleaning power of 10-12%, with a more streamlined formula suitable for sensitive skin

Application Details: Compound 1-2% cocoamidopropyl betaine can further reduce irritation, with pH controlled at 5.5-6.5 close to the skin’s pH value

Concentrated Pet Bath Liquid

Core Value: High dilution ratio (1:20), suitable for large-scale cleaning of large pets, reducing the risk of licking

Application Details: mixed with 0.3% tea tree oil to enhance antibacterial effect without affecting foam

Procurement and Storage
