🧪 Washing Auxiliary Powders and Liquids for Oil and Blood Stains – Production, Formulation and Properties
Overview:
Washing Auxiliary Powders and Liquids for Oil and Blood Stains are high-performance pre-treatment and additive formulations designed to remove tough organic and protein-based stains such as grease, oil, blood, food residues, and sweat.
These auxiliaries enhance the cleaning power of standard detergents, acting as stain-dissolving boosters that work effectively even at low washing temperatures.
They are available in both powder and liquid forms, each optimized for specific usage:
-
Powders: For soaking and additive use in main washing cycles.
-
Liquids: For direct spot-cleaning or dosing in automatic washing machines.
These products combine enzymatic, surfactant, and solvent-based systems to deliver deep stain removal without damaging fabrics or altering color tones.
Production and Formulation:
The Washing Auxiliary Manufacturing Process varies slightly between powder and liquid types, but both focus on achieving high soil removal efficiency, enzyme stability, and controlled foaming.
Powder Formulations
Powder auxiliaries are generally produced by dry blending and granulation.
Key components include:
-
Surfactants: LAS, AOS, SLS, or nonionics – remove greasy and oily stains.
-
Enzymes: Protease, amylase, lipase – degrade protein- and starch-based stains.
-
Builders: Sodium carbonate, zeolite – enhance alkalinity and cleaning efficiency.
-
Oxygen Bleach (optional): Sodium percarbonate – assists in oxidation of organic residues.
-
Anti-Redeposition Polymers: CMC – prevent soil redeposition on fabrics.
-
Perfume and Optical Brighteners: For freshness and fabric brightness.
Production Steps:
-
Dry Mixing: All dry ingredients are homogenized.
-
Agglomeration (optional): Improves flowability and dust control.
-
Screening: Ensures consistent particle size.
-
Packaging: Packed in moisture-proof containers to preserve enzyme activity.
Liquid Formulations
Liquid auxiliaries are designed for direct application or machine dosing systems and typically include solvent and surfactant mixtures with enzyme stabilization.
Key components include:
-
Nonionic Surfactants: Fatty alcohol ethoxylates, alkyl polyglucosides – dissolve oils and greases.
-
Enzymes: Protease and lipase – target protein and fat-based stains.
-
Solvents: Butyl diglycol, propylene glycol – assist in stain softening and emulsification.
-
Chelating Agents: Sodium gluconate, EDTA – enhance cleaning in hard water.
-
pH Regulators: Maintain mild alkalinity for fabric safety.
-
Fragrance and Preservatives: Improve consumer appeal and stability.
Production Steps:
-
Blending: Surfactants and solvents are mixed until homogeneous.
-
Enzyme Addition: Added at low temperature (below 40°C).
-
Stabilization: Adjusted with chelators and preservatives.
-
Filling: Bottled in opaque containers to protect enzyme integrity.
Properties:
-
Physical Form: Powder or liquid (clear or opaque).
-
Active Components: Enzymes, surfactants, builders, solvents.
-
Foam Level: Controlled low foam, suitable for machine washing.
-
pH (1% solution): 8.5–10.
-
Solubility: Excellent in water.
-
Stain Removal Efficiency: High for grease, oil, blood, and food residues.
-

-
Compatibility: Works with all laundry detergents.
-
Shelf Life: 12–18 months (powders); 9–12 months (liquids).
Advantages of Washing Auxiliary Powders and Liquids:
-
Deep cleaning for tough organic and greasy stains.
-
Compatible with enzyme-based detergents.
-
Safe for both white and colored fabrics.
-
Low-foam and machine-safe formulations.
-
Improves overall washing performance and brightness.
-
Supports eco-friendly, phosphate-free cleaning chemistry.
Summary:
Washing Auxiliary Powders and Liquids for Oil and Blood Stains are essential components of modern laundry systems, combining biochemical enzyme action and chemical surfactant technology for superior stain removal.
They bridge the gap between detergents and professional pre-treatment agents, delivering powerful results without harsh chemicals.
These formulations are the backbone of premium, performance-driven laundry care, offering consumers and industrial users effective, fabric-safe, and sustainable stain-removal solutions.
