AutoBlend System - Continuous Production of Liquid Detergent
Liquid detergents that contain a high content of soaps to mask the hardness of the water have conquered a substantial market share.
Liquid Detergents: Composition, Types, and Manufacturing Process
Water Hardness and Detergent Formulation Challenges
Liquid detergents often rely on high soap content to mask water hardness, unlike powders that use insoluble silicates like Zeolith A.
Surfactant Categories Used in Liquid Detergents
- LAS: Linear alkyl-benzene-sulfates (main anionic).
- FAS: Fatty alcohol-sulfates (used for sensitive fabrics and dishwashing).
- APG: Alkyl-poly-glycosides (biodegradable non-ionics).
- Esterquats: Cationics for wool care and fabric softening.
Growth in Liquid Detergent Demand
Rising energy costs have made liquid detergent production more profitable, resulting in a diverse product range for consumers.
Types of Consumer Liquid Detergents
- General purpose detergent
- For colored fabrics
- For sensitive fabrics
- For wool garments
Key Additives in Liquid Detergent Formulation
- Enzymes (protease, amylase, lipase)
- Optical brighteners
- Disinfectants and antibacterial agents
- Foam-control agents
- Color-protecting substances
- Fragrances
- Ethanol for viscosity control
Three-Step Manufacturing Process
Step 1: Initial Neutralization
Combination of aqueous caustic and sulfonic acid in a static mixer for near-complete neutralization.
Step 2: Fatty Acid Addition and Cooling
Fatty acids are mixed dynamically, triggering an exothermic reaction; a cooling loop ensures safe temperature before injecting additives.
Step 3: Final Mixing and Quality Control
Remaining formulation ingredients are added; viscosity and pH are actively monitored, and the product is cooled for filling.
