>Formula combination: LABSA+AES is a classic combination of liquid detergents; AES foam, mild, hard water resistance is better than LABSA. 
Core Advantages 
1. foam is rich, delicate, and has strong decontamination and emulsification power 
Excellent foaming ability, foam is durable and stable; Has good emulsification and peeling ability against oil and dust, suitable for products such as tableware, bathing, laundry detergent, etc. 
2. Outstanding resistance to hard water 
Good resistance to calcium and magnesium ions, less attenuation of foam and washing effect in hard water environment, superior to LAS/LABSA. 
3. Less stimulating 
Compared to K12, AES has less skin irritation and is suitable for personal care products such as shampoo, shower gel, and hand sanitizer. 
4. Excellent compatibility 
It can be compounded with anionic, nonionic, and amphoteric surfactants (6501, betaine), with flexible formula adjustment and easy thickening. 
5. Good biodegradability 
Easy to biodegrade, environmentally friendly, meeting the environmental requirements of daily chemical and industrial cleaning. 
Main applications 
1. Daily chemical cleaning and care (maximum use) 
Shampoo, shower gel, hand sanitizer, dishwashing detergent, laundry detergent, car wash detergent. 
2. Industrial cleaning 
Hard surface cleaner, metal degreaser, textile refining agent, chemical fiber cleaner, with anti-static effect. 
3. Other industries 
Leather additives, papermaking de ink, oilfield foaming agents.
