Product Overview
Laundry in-wash fragrance beads function as scent-booster delivery systems engineered for bulk private label and retail packaging. Formulated using extruded water-soluble polymer matrices (such as modified starch or PVA derivatives), these beads encapsulate high concentrations of fragrance oils and fixatives. The carrier matrix dissolves completely in standard wash temperatures, releasing sustained aroma compounds that bind to fabric fibers during the main wash cycle.

Key Features
Controlled Scent Release:
Micro-encapsulated fragrance technology ensures aroma retention through the wash cycle and up to 12 weeks of dry storage freshness.
01
Complete Dissolution:
Engineered to dissolve fully in wash water temperatures ranging from 20°C to 90°C without leaving waxy residues or clogging dispensing drawers.
02
High Fragrance Load:
Formulated to carry up to 15% pure fragrance oil and fixatives without compromising pellet structural integrity.
03
Fabric Compatibility:
PH-neutral formulation prevents fiber degradation across cotton, synthetic blends, and delicate textiles.
04
Flowability:
Anti-caking surface treatment ensures smooth, consistent feeding in high-speed rotary packaging and dispensing equipment.
05
Standard Starch-Based Beads: Biodegradable, cost-effective carrier matrix optimized for mass-market retail detergent brands.
PVA-Coated Sustained Release Beads: Higher durability matrix providing extended fragrance longevity for premium and specialty linen care lines.
Custom Fragrance Profiles: Tailored aroma formulations aligned with international safety standards, spanning floral, woody, citrus, and hypoallergenic scent categories.
Color Customization: Single-tone, multi-color speckled, or pearlized pigment finishes matched to specific brand identity requirements.
Suitable Fibres & Applications
Natural Fibres:
Cotton, linen, wool, and silk (safe for standard and delicate wash cycles).
Synthetic & Blends:
Polyester, nylon, spandex, and poly-cotton blends (prevents static-induced scent stripping).
End-Use Sectors:
Consumer retail pods/bottles, commercial hospitality laundering (hotels, spas), healthcare linen refreshing, and fitness apparel care.
Application & Process Considerations
Dosage Parameters: Recommended dosage ranges from 15g to 30g per standard 5kg load, adjustable based on water hardness and desired scent intensity.
Addition Method: Added directly into the washing machine drum prior to loading laundry; incompatible with liquid fabric softener dispenser drawers.
Storage Requirements: Store in sealed, moisture-proof containers at temperatures below 30°C and relative humidity under 60% to prevent premature pellet softening or clumping.
Production Process: Granulation, core extrusion, fragrance vacuum-infusion, cooling stabilization, and anti-caking surface coating.
Equipment: Twin-screw extruders, continuous spray-coating drums, and automated optical sorting systems to eliminate deformed pellets.
Testing Protocols:
• Moisture balance analysis via Karl Fischer titration.
• Dissolution speed testing in standard stirred-beaker apparatus at 20°C.
• Gas Chromatography-Mass Spectrometry (GC-MS) for volatile fragrance compound profiling.
• Bulk density and crushing strength verification.
Compliance Verification: Facility management systems aligned with recognized quality assurance frameworks, safety data validation, and restricted substance compliance documentation.
Packaging & Supply
Bulk Packaging:
25kg fiber drums with double-layer PE liners or 500kg FIBC bulk bags equipped with moisture barriers.
Private Label Support:
Custom bulk manufacturing, container loading optimization, and export documentation handling.
Production & Sampling Lead Times:
Standard prototype sampling and lab dip formulations complete within 7 to 10 days; mass production runs ship within 15 to 25 days following formulation and fragrance sign-off.
Technical Documentation Resources:
Downloadable Technical Data Sheets (TDS), Safety Data Sheets (SDS), and parameter comparison matrices are accessible via direct inquiry to accelerate procurement vetting.
