Colored Speckles are specialized functional particles designed to provide visual enhancement and brand distinction in a wide range of industrial products. High-quality speckles are characterized by their exceptional color fastness, stability against migration, and consistency in appearance—key factors that drive consumer preference and product performance in competitive markets.

COLORED SPECKLES

Our Colored Speckles are precision-engineered particles produced through advanced synthesis and coating technologies. Available in controlled micron or nanometer scales (typically 10nm–10μm), they exhibit intense color strength, uniform shape and size distribution, and robust chemical and physical stability. These properties ensure reliable dispersion behavior, batch-to-batch reproducibility, and compatibility with diverse formulation environments.

CORE FEATURES

Chemical Coloration: Color is introduced through detergent-grade colorants embedded in a carrier salt matrix, giving each speckle a stable and uniform color.

Controlled Particle Size: Speckles are produced within a controlled particle size range to match detergent base powder and support uniform dry blending.

Free-Flowing and Low Moisture: The product remains free-flowing with low moisture content, reducing caking and supporting stable storage and dosing.

Batch-to-Batch Consistency: Each lot is routinely tested for bulk density, particle size, pH, loss on drying, and dissolution time, with COA available for every shipment.

Colored Speckles Core Performance Advantage

Consistent Particle Size for Uniform Blending

Particle size is controlled within a narrow distribution to match detergent base powder, reducing segregation during mixing and keeping the speckles evenly distributed in the final product.

Free-Flowing with No Agglomeration

The speckles are designed to remain free-flowing under normal storage and transport conditions, with no caking or agglomeration, supporting stable feeding and dosing on detergent production lines.

Detergent-Compatible pH and Low Moisture

The product is formulated within a pH range suitable for detergent systems and with low loss on drying, helping maintain stability when combined with surfactants, builders, and optical brighteners.

Fast Dissolution and Batch-to-Batch Consistency

The speckles dissolve readily under washing conditions, and each batch is routinely tested for bulk density, particle size, pH, moisture, and dissolution time, with COA available for every lot.

Mixing Method

Colored speckles are designed for dry blending with detergent base powder. Add at the required ratio and mix uniformly; no ultrasonic treatment or solvent dispersion is required.

Storage Conditions

Store in a dry, ventilated area away from moisture and strong oxidizing agents. Keep packaging sealed after opening to prevent caking and color migration.

Safety Protection

Wear a dust mask, gloves, and goggles during handling to avoid dust inhalation and eye contact. Maintain adequate ventilation in the blending area.

Waste Disposal

Dispose of unused speckles and packaging according to local industrial solid waste regulations. Safety data sheets are available upon request.

Colour	Colour Card Title	Core Features
Red	Red Speckles — High-Contrast Visual	Strong visual contrast in white or blue powder; supports the perception of effective cleaning; free-flowing, no agglomeration, fast dissolution
Blue	Green Speckles — Eco / Natural Positioning	Suited to eco/natural positioning; differentiates green-concept detergent formulations; free-flowing, controlled particle size, fast dissolution
Green	Blue Speckles — Whitening-Boost Visual	Visual whitening direction; complements optical brighteners and helps neutralize yellowing; classic blue-on-white contrast; free-flowing, fast dissolution
Violet	Violet Speckles — Color-Balancing / Premium	Color-balancing and premium visual direction; alternative to standard blue or green aesthetics; free-flowing, controlled particle size, fast dissolution

Red Speckles

Red Speckles are heat-stable and resistant to fading during detergent production and storage. They can be used in formulations containing antibacterial agents, and mix evenly with detergent base powder without segregation.

Blue Speckles

Blue Speckles provide a clean, bright visual contrast in white detergent powder and visually reinforce the perception of powerful stain removal. They dissolve readily in wash liquor and disperse evenly in the detergent matrix.

Green Speckles

Green Speckles are suitable for eco-positioned detergent formulations and are associated with color-care and gentle-wash claims. They disperse evenly in the detergent matrix without interfering with detergent performance.

Violet Speckles

Violet Speckles provide a distinctive visual cue for premium or specialty-care detergent lines. They are color-stable during storage and disperse evenly in detergent base powder.

Enhanced Visual Appeal

Deep red, deep green, deep blue, and violet speckles can be added at different ratios to create a colorful product appearance, increase shelf visual impact, and attract consumer attention.

Color-Coded Product Communication

Brands can use different speckle colors as visual cues linked to specific care messages—such as stain removal, color care, or freshness—helping consumers understand product positioning at a glance.

Differentiated Product Positioning

Custom color combinations and speckle specifications help detergent brands stand out on shelf and build a recognizable product identity that is distinct from competitors.

FAQ

Will the color of Colored Speckles fade during the storage of laundry detergent?

Can’t. Our Colored Speckles are made of special coloring agents that are resistant to light and temperature. After rigorous stability testing, they can maintain their color for more than 24 months under the normal storage conditions of laundry detergent (temperature -5 ℃~40 ℃, avoid direct sunlight) without fading or discoloration, ensuring long-term stability of the product appearance.
Why our speckles won’t bleed or fade – check the facts

Do Colored Speckles contain harmful ingredients that affect the safety of laundry detergent?

Completely safe. All particles are made of food grade/daily chemical grade raw materials that comply with the GB/T 13171-2021 laundry detergent standard, and do not contain harmful substances such as heavy metals and fluorescent whitening agents. They have been tested by authoritative institutions such as SGS and CTI and are compatible with laundry detergent ingredients, without affecting their safety of use.

Are the speckles compatible with all detergent bases?

Our speckles are designed for excellent compatibility with standard detergent formulations, including those with high carbonate or sulfate levels. We recommend testing compatibility for any novel base formulations, and our technical team can provide support for this.

Are the speckles biodegradable and environmentally safe?

The environmental profile depends on the specific formulation. Many speckles use sodium sulfate, a naturally occurring salt, as a primary carrier. We offer solutions with biodegradable binders and coatings. Please contact us for detailed information on the environmental compatibility of our specific speckle products.

Will the speckles stain my fabrics or the washing machine?

No, when formulated correctly. Our speckles use high-stability dyes and pigments that are fully encapsulated. They are designed to dissolve completely in water, preventing any staining or dye transfer to fabrics or washing machine components.

What are the recommended storage conditions?

Store masterbatch in a cool, dry place away from direct sunlight and moisture. Proper storage ensures optimal performance and shelf life.
