Laundry Detergent

Product Overview

Industrial-grade liquid detergent engineered with a bio-active peptide matrix for high-capacity tunnel washers and commercial front-load extractors. Formulated for institutional linen processors, commercial laundries, and uniform rental operations. Supplied in bulk containers (200L drums and 1000L IBC totes) for B2B contract manufacturing, private-label distribution, and institutional supply chains.

Peptide Formula & Key Ingredients

Active Peptide Complex:

Engineered short-chain polypeptides targeting specific proteinaceous soils (blood, sebum, food residues) at molecular cleavage sites.

Surfactant Matrix:

Multi-blend system combining alcohol ethoxylates (non-ionic, 15% to 20% active) and linear alkylbenzene sulfonate (anionic, 10% to 15% active) for targeted grease emulsification.

Enzyme Blend:

Stabilized protease, amylase, and cellulase complexes functioning synergistically with the peptide matrix.

Chelating Agents:

Sodium gluconate and MGDA to bind calcium and magnesium ions in hard water, preventing mineral ash redeposition on textiles.

Anti-Redeposition Agents:

Carboxymethyl cellulose (CMC) to suspend removed particulate soils in the wash liquor.

Functional Benefits

Low-Temperature Activity: Operates effectively at 30°C to 40°C, reducing steam and natural gas heating consumption in commercial boiler systems by 25%.

Fiber Protection: Preserves cotton and polyester-cotton blend tensile strength, extending institutional linen lifespan by up to 30 wash cycles compared to high-alkaline powders.

Enzyme-Peptide Synergy: Accelerates stain hydrolysis without requiring aggressive chlorine bleach, minimizing chemical degradation of fibers.

Controlled Foaming: Low-foam surfactant architecture prevents pump cavitation and pressure drops in high-agglomeration industrial tunnel washers.

Texture & Product Format

Homogeneous, free-flowing liquid concentrate designed for automated chemical dosing systems in commercial laundries. Miscible in cold and warm water without phase separation or gel formation in feed lines. Viscosity optimized to prevent residue buildup in peristaltic pump tubing and injection nozzles.

Applications

Hospitality Linens:

Hotel bed sheets, toweling, and tablecloths requiring high whiteness retention and minimal fiber fraying.

Healthcare Textiles:

Patient garments and surgical drapes processed under low-temperature thermal disinfection regimes.

Industrial Workwear:

Mechanics' coveralls, oil-field uniforms, and food-processing aprons contaminated with heavy mineral oils and animal fats.

Formulation & Customization

Viscosity Tuning: Adjustable from 200 mPa·s to 1200 mPa·s to match specific peristaltic or venturi dosing equipment.

Enzyme Profiling: Additions of lipase for heavy fat loads or mannanase for cosmetic/food stains upon request.

Fragrance Profiles: Unscented (industrial standard) or custom encapsulation scents meeting occupational safety and fragrance concentration limits.

Concentration Ratios: Available in 2X, 3X, and 5X industrial concentrates to reduce freight volume for overseas shipments.

Manufacturing & Quality Control

roduction Facility:

PBatch-controlled stainless steel (316L) mixing vessels equipped with high-shear rotor-stator homogenizers to ensure uniform peptide dispersion.

Filtration:

100-mesh inline filtration prior to filling to eliminate particulate contaminants.

Batch Testing Protocols:

Every production batch undergoes refractive index, pH, active matter titration, and microbial limit testing prior to release.

Traceability:

Laser-etched lot numbers on containers linking to raw material certificates of analysis and retained sample logs for 24 months.

Packaging Options

200L HDPE Drums: Heavy-duty blow-molded polyethylene, UN-rated for maritime and land transit.

1000L Intermediate Bulk Containers (IBC Totes): UV-stabilized HDPE tanks with integrated bottom discharge valves and tamper-evident seals.

Private Label Options: Custom silkscreen printing or weather-resistant adhesive labeling with buyer logo, multilingual hazard warnings, and customized dilution instructions.

FAQ

Q: What is the recommended dosing concentration for standard commercial tunnel washers?

A: The baseline dosing rate is 3 to 5 grams of liquid concentrate per kilogram of dry laundry, depending on water hardness and soil levels. Site-specific titration curves are provided upon onboarding.

Q: Does the peptide formulation require a separate chlorine bleach step? No.

A: The peptide-enzyme complex breaks down protein matrices directly. For sanitization, compatible hydrogen peroxide or peracetic acid boosters can be injected in the bleach compartment without denaturing the active peptides.

Q: What is the shelf life of the liquid concentrate under warehouse conditions?

A: Storage life is 12 months when kept in sealed containers between 5°C and 35°C out of direct sunlight. Active enzyme retention remains above 90% at 12 months under these conditions.

Q: Are the raw material ingredients compliant with major chemical regulations?

A: Yes. All surfactant and active ingredient inputs are fully registered under applicable regional chemical management frameworks, and the formulation conforms to standard biological detergent biodegradability requirements.

Q: Can the viscosity be adjusted for older, low-pressure chemical injection pumps?

A: Yes. We modify the rheology modifier percentage during batching to lower the viscosity to 250 mPa·s, ensuring smooth flow through gravity-fed or low-pressure diaphragm dosing lines.

Q: What documentation is supplied with initial sample shipments?

A: Each sample order includes a Certificate of Analysis, Safety Data Sheet compliant with hazard communication standards, and technical data sheets detailing active matter and enzyme activity assays.
