Lutein 5% CWS Powder for Water-Based Formulations
Lutein 5% CWS Powder is a water-dispersible lutein extract from marigold. It is formulated from Tagetes erecta flowers and comes in microencapsulated powdered form, offering formulators an alternative to traditional oil-soluble lutein in various water-based applications such as instant beverages, powdered formulations, liquid nutritionals, and more.
The CWS format will disperse more easily in water, unlike regular lutein powders where lutein is not water-soluble. This provides an advantage for making any formulations in which uniform dispersion in the product is a critical processing factor.
The greatest benefit to manufacturers is its formulating delivery method: a standardized lutein ingredient in a dry, easy-to-handle powder, ideal for water-based product development. Technical documentation and samples are available for evaluation of product formulations, and Kingsci supplies bulk CWS lutein for supplement, beverage, food, and nutrition manufacturers.

Why Choose a CWS Format?
1. Improved Cold-Water Dispersion
May be formulated in aqueous systems, as it disperses more readily in cold, water-based systems, facilitating the incorporation of lutein into aqueous formulations.
2. Formulation-Friendly Powder
Supplied as a dry powder that is easy to weigh, blend, and pre-mix, and can be processed downstream.
3. Suitable for Water-Based Products
A convenient powder for instant beverages, functional drinks, liquid foods, and other water-based products.
4. More Flexible Formulation Development
An alternative to traditional Lutein Powder for formulators when the formulation calls for better dispersion in water.
5. Standardized 5% Specification
A defined assay level allows for easier dosage calculations, premix preparation, and formulation consistency.
6. Convenient for Processing
Available in bulk with technical documentation and samples for lab testing, pilot production, and commercial formulation.

Formulation Considerations
1. Dispersion Method
This Lutein Powder is specifically formulated to disperse in cold-water systems. Good agitation and mixing time can result in a more balanced distribution within the formulation.
2. Water Temperature
The wetting and dispersion properties of powder may be affected by water temperature. When using for instant beverages and drink powders, manufacturers should consider the ingredients at the actual reconstitution temperature at which the finished product will be served.
3. Mixing Order
Dispersion may vary under different conditions depending on the order in which ingredients are added as a CWS. Adding compatible dry ingredients or carefully introducing them into the liquid phase before processing can be used to limit localized aggregation during processing.
4. pH & Ionic Strength
The formulation pH and ionic strength may affect the stability and dispersion of the delivery system. Compatibility should thus be evaluated under the final conditions of pH and ingredient composition of the intended product.
5. Ingredient Compatibility
Other functional ingredients such as minerals, proteins, acids, flavors, and sweeteners can interact with the CWS system. The pilot scale can be used when preparing complex beverage and/or nutrition formulations.
6. Processing Conditions
The physical properties of the product may change due to high shear mixing, homogenization, heating, etc. during processing. The processing conditions should be optimized as per the final dosage form.
7. Final Product Evaluation
The performance should be checked not only by a water dispersion test in the laboratory, but also in the final formulation. Kingsci is able to supply samples and technical documents for formulation trials and product evaluation.
FAQ
What does CWS mean in Lutein 5% CWS Powder?
Cold Water Soluble/Dispersible (CWS) indicates how the powder is intended to work in cold water-based formulations. The CWS format does not alter the nature of lutein itself, as it remains water-insoluble; rather, it enhances the dispersibility of the lutein in an aqueous system.
Is Lutein 5% CWS Powder suitable for beverages?
Yes. The formulation is especially designed to be used in applications where lutein has to be added to water-based systems such as instant beverage powders and selected functional beverage formulations.
What is the difference between CWS lutein and regular lutein powder?
Lutein powder is a natural hydrophobic product and is not completely soluble in water. CWS lutein is formulated in a special way for water-based systems to enhance dispersion.
Can Lutein 5% CWS Powder be used in instant drink powders?
Yes. It is possible to use it for instant drink powders where the finished product is rehydrated with water.
Does CWS lutein completely dissolve in water?
The use of CWS does not imply that lutein is being dissolved at the molecular level. The product is designed to be more effective in cold water systems. The actual dispersion performance is dependent on the formulation and processing conditions.
Can you provide samples?
Yes. Kingsci is able to supply samples for formulation evaluation. When requesting a sample, customers may provide their proposed product format, dosage, and application.
