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 coloring: embedding organic dyes or inorganic chromophores in the particle matrix

Physical coloration: Surface plasmon resonance at the nanoscale (such as gold nanoparticles appearing red)

Structural color: Selective reflection of specific wavelength light by periodic microstructures

Unique advantages: excellent dispersion, strong stability, and the ability to integrate multiple functions.

Colored Particles Core Performance Advantage

Accurate and controllable color adjustment

Accurate color control can be achieved by adjusting synthesis parameters such as reaction temperature, reactant ratio.

Excellent dispersion stability

Surface modification of specific functional groups to disperse particles in water/organic solvents with a shelf life of>6 months.

Broad spectrum chemical stability

Inorganic based particles can withstand a pH range of 2-12 and high temperatures exceeding 800 ℃; Polymer based particles have excellent solvent resistance.

Customized function integration

Support surface functionalization modification (such as coupling antibodies for targeting and drug loading for integrated diagnosis and treatment) to meet personalized needs.

Dispersion method

Nano level ultrasonic treatment is recommended (300W, 5-10 minutes); Micron level magnetic stirring (500rpm, 30 minutes)

Storage conditions

Metal based particles should avoid contact with thiols; Fluorescent particles need to be stored away from light; High temperature storage test data.

Safety protection

Wear nitrile gloves and goggles during operation; Organic dispersion systems need to be operated in a fume hood

Waste disposal

Treat according to chemical solid waste, provide local environmental standards link

Red particles

Have good heat resistance and stability, and are not easily faded during the production and storage of laundry detergent. Can be combined with sterilization function, easy to mix evenly with laundry detergent particles.

Blue particles

Made from high-quality raw materials with pure color, they can give laundry detergent a fresh visual experience and represent powerful stain removal function. Easy to dissolve and leave no residue during the washing process.

Green particles

comply with environmental standards, symbolizing color protection, gentleness and other characteristics. Adding them to laundry detergent can give people a natural and safe feeling. Disperse evenly without affecting the effectiveness of the laundry detergent.

Purple particles

With a unique color, they can serve as a symbol of high-end laundry detergent and represent special care functions. Good stability, able to maintain color for a long time.

Enhance appearance appeal

Various colored particles such as orange, red, blue, green, purple, etc. can be added to laundry detergent in different proportions to create a colorful and beautiful product appearance, increase the visual impact of the product, and attract consumers to purchase.

Intuitive display function

Different Colored Speckles can be associated with specific functions, such as blue particles representing strong stain removal, green particles representing color protection, red particles representing sterilization, etc., allowing consumers to quickly understand product functions from the appearance.

Creating differentiated products

By using unique Colored Speckles formulas and color combinations, laundry detergent products can be distinguished from competitors in terms of appearance and functionality, forming unique product selling points and enhancing market competitiveness.

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.

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.
