Marigold Extract is a botanical ingredient obtained from marigold flowers, commonly identified as Calendula officinalis L. Also known as pot marigold or calendula, this plant belongs to the Asteraceae family, traditionally also referred to as Compositae. The flowers contain a range of naturally occurring botanical constituents, including flavonoids, carotenoids, triterpenoids, and other plant compounds.
Marigold Extract is available in different forms, including powdered flower extracts and liquid extracts prepared using different extraction methods and carriers. These products may differ in appearance, solubility, concentration, marker compounds, and intended application. Buyers should therefore confirm the exact product grade before using a specification or assay value in product documentation.
The botanical name of marigold used for this product is Calendula officinalis L. The flower is a commonly declared plant part for Calendula flower extract. However, the term “Marigold Extract” can be used broadly in commercial catalogues, so the plant part should be verified against the technical data sheet and certificate of analysis.
The extraction process affects the final composition of the material. A water-based extract may differ from a hydroalcoholic extract, while liquid preparations may contain carriers such as glycerin or glycols. Powdered extracts may also contain a processing carrier, depending on the manufacturing method. These differences can affect the finished product's colour, solubility, concentration, and analytical results.
The physical characteristics of Marigold Extract depend on the grade supplied. Powdered material may range from yellowish or reddish-yellow to brown, while certain liquid preparations may be light yellow or amber. These descriptions are examples from commercial product documentation, not universal acceptance limits.
The product specification should state the actual appearance, odour, moisture content, particle size, solubility, and other relevant parameters for the selected grade. If the extract is standardized, the marker compound and assay method should also be declared. Lutein, flavonoids, and other botanical constituents may be used as analytical markers in particular products, but their percentages should not be assumed to apply to every Marigold Extract.
Marigold Extract is used as a botanical ingredient in suitable personal-care, cosmetic, and other formulation applications, depending on its grade and regulatory status.
Potential application categories include:
The suitability of an extract depends on the extraction method, carrier ingredients, quality documentation, formulation requirements, and applicable regulations. A cosmetic-grade liquid extract should not automatically be treated as interchangeable with a powdered botanical extract intended for a different application.
Quality assessment should start with confirmation of the botanical name, plant part, extraction method, and batch identity. The certificate of analysis should identify the tests performed, the applicable limits, and the actual results for the supplied batch.
Depending on the grade, relevant quality parameters may include identification, loss on drying, ash, particle size, marker-compound assay, heavy metals, microbial limits, pesticide residues, and residual solvents. For liquid extracts, carrier composition, pH, density, and preservation details may also be relevant.
A standardization claim should always specify the marker compound, minimum or target content, and analytical method. For example, a commercial product described as standardized to lutein should have documentation confirming the declared lutein content and the test method used. A general flower extract should not be described as containing a particular lutein or flavonoid percentage without evidence for that grade.
When selecting Marigold Extract for a formulation, buyers should review the following information:
For product and formulation enquiries, buyers should request the available grade information, current technical data sheet, certificate of analysis, and packaging details from Swapnroop. These documents help confirm whether the product meets the intended technical and regulatory requirements.
Product descriptions should accurately represent the grade available. Numerical specifications, standardization percentages, certifications, and claims about suitability for a particular application should be included only when supported by the appropriate documentation.
Marigold Extract is a botanical ingredient commonly obtained from the flowers of Calendula officinalis L. Its composition and physical characteristics depend on the extraction process and product grade.
The botanical name commonly used for pot marigold is Calendula officinalis L.
CAS 84776-23-8 is listed for Calendula officinalis flower extract. Confirm that this identifier matches the exact ingredient and grade being documented.
Yes. Commercial documentation describes both powdered extracts and liquid preparations. They can differ in concentration, carriers, solubility, and intended use.
No. Lutein standardization applies only to specific grades with supporting analytical documentation. Do not apply a standardized assay percentage to an unspecified extract.
Depending on the grade, check botanical identification, appearance, loss on drying, ash, marker assay, heavy metals, microbial limits, residual solvents, and other applicable quality parameters.
Follow the storage conditions stated in the current technical data sheet or product label. Storage requirements may differ between powder and liquid preparations.
Buyers should request the current technical data sheet and batch-specific certificate of analysis to confirm the product's identity, grade, assay, and quality limits.
