Description

A colorful speckle composition in laundry detergent powders and tablets is diverse. The speckles feature exceptional dissolution behavior and flow properties and should leave no residue or cause adverse effects, such as staining, on the laundry. 

The overall composition usually comprises a major proportion of white or neutral particles and a minor proportion of colorful speckles. However, it’s not uncommon to have a compound featuring a significant proportion of colorful particles as the base, mixed with a small amount of a contrasting hue. 

Apart from purely aesthetic purposes, colorful speckles can serve some practical functions, too. Including visually contrasting particles can be a clue to the consumer, indicating the presence of some specific ingredient, such as bleach.

If used solely as a visual enhancer, the colorful speckles composition is commonly present in an amount of 1% – 3%.

The colorful speckles are especially suitable for incorporation in detergent compounds which contain sodium chloride.

Stability/Shelf life

Stable under regular conditions and recommended storage. 

Storage: Tightly closed original package, in a cool, dry, well-ventilated area, away from weight press and sunlight. 

Manufacturing

The speckle composition can be prepared by various methods for treating the sodium chloride with the colorant, by any suitable mixing equipment. It’s advisable to use the mixer with stainless steel interior surface to neutralize sodium chloride’s corrosive properties. 

During a procedure, the sodium chloride is dosed into a machine, together with the colorant and the opaque white pigment, followed by a binder. A minor proportion of the silica is preferred, but not a necessary component, added with the sodium chloride. Flow aid is commonly added last. Thorough mixing ensures homogeneity, and finally, the composition dries.

Industry use

The colorful speckles are principally used to improve the visual effect of detergent powder. As an ingredient, it can be added to a previously prepared detergent mix directly, in 1%-3% of the final compound. 

Consumer use

Colorful speckles are a common ingredient in household products, such as detergents, various cosmetic products, toothpaste, and soaps. 

Solubility

Soluble in water.

Common synonyms

Sodium chloride

Sodium sulfate

Anhydrous color speckles

Sodium carbonate color speckles

FAQ

Q1: What colors are available?

A: Many different colors are available including red, green, blue, orange, pink and others…

Q2: Can different colors be mixed together?

A: Yes, they can be mixed together. Normally, the speckles of different colors will be packaged separately. However, according to requirement of the clients, we can mix them together. 

Q3: When buying colorful speckles, are there any factors that I must pay attention to?

A: Yes, as mentioned above, you should pay attention to the granularity, the rate of dissolution and the color of the speckles. The “color” here is more than just the diversity of colors. The important thing is that good colorful speckles will not dye the clothes during washing.
