Lutein Oil

Free Lutein in an Oil-Based Format for Softgels, Liquid Products & Lipid-Phase Formulations

Lutein Oil is derived from marigold and is composed of free lutein in an oil-based carrier system. It comes in varying concentrations (5%, 10%, 20%) and is formulated for the manufacturer who requires a lipid-compatible format for softgels, liquid nutritional products, oil-based premixes, and selected functional formulations.

The advantage of Lutein Oil Suspension is that it is available in a physical form along with the free form.

Lutein is a fat-soluble carotenoid and is thus frequently added to a formulation that contains an oil phase or a lipid phase. The provision of the ingredient in an oil-based material may make it easier for the manufacturers making the oil-filled dosage forms and liquid systems to have an ingredient as a powder to begin with.

This formulation is especially important when the formulation process is carried out in the presence of a lipid carrier. Instead of formulating a dry lutein ingredient into an oil-based system during the development process, manufacturers may assess an oil-based lutein ingredient directly in their system.

The product comes in various lutein content levels, enabling formulators to achieve the desired loading of active, dosage, carrier volume, and manufacturing conditions.

Both Lutein Oil and Lutein Ester Oil are oil-based ingredients, but they are not the same oil.

Lutein Oil is a source of free lutein, while Lutein Ester Oil is a source of lutein in esterified form. This distinction will impact formulation development of the ingredients.

If there is a particular need for a free lutein in an oil-based form, Lutein Oil would be more suitable to use. If an esterified lutein source is desired, then Lutein Ester Oil should be tested separately.

The product is not to be defined by industry; rather, its formulation environments are the ones in which an oil-based free lutein ingredient can be useful.

Oil-Filled Softgels

It can be tested in soft-gel formulations in which the lipid carrier used for the fill is compatible with Lutein Oil. The 3 choices (5%, 10% and 20%) offer flexibility in calculating the amount of lutein needed in the final fill.

Liquid Nutritional Products

It is a liquid source of free lutein which can be added to the food formulation during formulation development for liquid supplements and other food nutritional products with an oil phase.

Multi-Carotenoid Oil Blends

For manufacturers designing carotenoid combinations, it can be used to test in conjunction with other lipid-soluble ingredients. All of the above must be considered in the total mixture, including compatibility, concentration, carrier selection, and finished-product stability.

Custom Lipid Premixes

Oil-Suspended Lutein can be used as part of a variety of fat-soluble nutrient ingredients that must be mixed together before being added to oil in a filling or further processed product.

Selected Functional Food & Cosmetic Systems

The ingredient can also be tested in appropriate lipid phase products, such as fat blended foods, emulsified systems, cosmetic oils, and other lipid phase products, depending on compatibility and regulatory needs for the targeted market.

The type of assay used depends upon the dosage level of the finished product and on the carrier amount that can be formulated into the product.

5% Lutein Oil

A formulation with a lower concentration if a larger amount of carrier is ok or if it is desirable to gradually incorporate the active.

10% Lutein Oil

Moderate lutein loading option for those manufacturers who prefer to keep their product in a fat-based format.

20% Lutein Oil

A higher concentration application option for those for whom reducing the amount of carrier needed per serving/batch is critical.

The final choice should depend on the desired lutein level, fill weight, carrier system, processing parameters, and specifications of the finished product.

Formulation performance is dependent on more than just the lutein assay, as Lutein Oil is a carotenoid-rich, oil-based ingredient.

Light protection

Avoid unnecessary exposure to strong light for storage, handling, and processing.

Oxygen management

Reduce the amount of time equipment is exposed to air during manufacturing and packaging.

Temperature control

Avoid unnecessary high temperatures, especially for longer periods of processing or storage.

Carrier compatibility

Test for compatibility before scale-up with selected oil, excipients, antioxidants, and other active ingredients.

Mixing conditions

Determine mixing and homogenization conditions suitable for the final formulation rather than using a standard processing process.

Finished-product stability

Assess stability in the full formulation since the performance of carotenoids is influenced by the environment (surrounding matrix, packaging, processing, and storage).

What is Lutein Oil?

Lutein Oil is an oil-based ingredient that is extracted from marigold flowers (Tagetes erecta L.) as free lutein. It is mainly intended for formulation systems in liquid and lipid phases.

What is the difference between Lutein Oil and Lutein Ester Oil?

Lutein Oil has free lutein, while Lutein Ester Oil has esterified lutein. The two ingredients are thus in different active forms, and their choice should be based on the formulation goal.

What concentrations are available?

Kingsci provides Lutein Oil in concentrations of 5%, 10%, and 20% lutein (HPLC), which are the recommended concentrations.

Is Lutein Oil suitable for softgels?

Yes. It can be used in oil-based softgel systems with its oil-based format, but it is important to note that the carrier and fill formulation are compatible with each other.

Can Lutein Oil replace Lutein Powder?

Not universally. Lutein Oil is recommended for oil- and liquid-based systems, whereas dry Lutein Powder is used in most tablets, hard capsules, dry blends, sachets, and powder-based systems.

What should manufacturers consider when selecting a grade?

Target dose of lutein, assay, carrier volume, finished product format, processing conditions, and stability profile.

Can I request a sample?

Yes. Kingsci can provide B2B manufacturers with a sample, specification, COA, and technical data for evaluation of formulations.
