2. Core Product Advantages
Superior Anti-hardwater & Calcium Soap Dispersion
Performs stably in high-hardness water without foam collapse, far better anti-hardwater capacity than LAS and AES. Prevents dirt redeposition effectively during washingAslan.
Rich, Stable & Dense Foam
Fast foaming, long-lasting creamy lather; excellent detergency against sebum, oil and daily stains, great for high-foam cleaning formulas.
Mild & Low Irritation
Less irritating to skin and eyes than SLES & LAS, suitable for baby care and sensitive skin cleansing products, leaving non-dry skin feeling after rinse-off.
Excellent Compatibility
Perfectly compatible with anionic, nonionic, amphoteric surfactants (AES, LABSA, CAB-35, APG etc.), creates obvious synergistic cleaning effect to reduce total formula dosageYeser Chem....
Eco-friendly & Fully Biodegradable
High biodegradation rate, phosphorus-free, meets EU REACH and global environmental detergent standardsAslan.
Wide pH Adaptability
Stable within pH 6~12; not recommended for long-term use under strong acidic environment (pH＜4, easy hydrolysis).
3. Detailed Application Fields
Household Cleaning & Daily Washing
