Silkworm Pupa Oil Ethyl Alpha-Linolenate for Nutritional and Industrial Applications

Product Specifications

Product Overview

Silkworm Pupa Oil Ethyl Alpha-Linolenate is an oil-based ingredient derived from silkworm pupae oil through extraction and refining. It is offered as a specialized lipid raw material for manufacturers evaluating ingredients for nutritional products, personal care formulations, and selected industrial applications.

The product specification identifies an ethyl alpha-linolenate content of at least 40%. Its yellowish to yellow appearance, transparent liquid form, and defined quality indicators provide reference points for material inspection and formulation development.

For manufacturers and raw material distributors, the product can be evaluated according to composition, purity requirements, processing compatibility, and the quality standards applicable to the intended end use.

Key Product Features

1. Silkworm Pupa Oil as the Raw Material Source

The product is derived from silkworm pupa oil, providing an oil-based ingredient for further processing and formulation. Its suitability for a specific application should be determined by reviewing its verified chemical composition and technical documentation.

2. Defined Ingredient Content

The supplied internal specification sets the ethyl alpha-linolenate content at a minimum of 40%. This provides a starting point for manufacturers assessing raw material composition and establishing formulation requirements.

Buyers should confirm the analytical method and the exact identity of the measured compound with the supplier before finalizing technical specifications.

3. Clear, Transparent Oily Liquid

The finished product is described as a yellowish or yellow, clear and transparent oily liquid. Transparency is specified at 20°C, providing an additional appearance criterion for incoming quality inspection.

4. Multiple Quality Control Indicators

The internal specification includes limits for moisture and volatile substances, insoluble impurities, peroxide value, residual solvents, selected heavy metals, and microbiological indicators.

These parameters help buyers evaluate the material against their purchasing requirements. Additional tests may be necessary depending on the intended application and relevant market regulations.

5. Practical Bulk Packaging

The standard packaging format is a 25 kg plastic drum. Alternative packaging arrangements may be discussed according to customer requirements, order quantities, and transportation needs.

Technical Specifications and Quality Standards

The specifications above are based on the supplied product information. Buyers should request the latest technical data sheet, batch-specific certificate of analysis (COA), and applicable test methods to verify the current product requirements.

Potential Applications

Silkworm Pupa Oil Ethyl Alpha-Linolenate is listed for consideration in several nutritional, personal care, and industrial sectors. Its suitability depends on verified composition, formulation compatibility, safety requirements, and applicable regulations.

Nutritional Products and Functional Foods

The ingredient may be evaluated as a lipid-based raw material for nutritional formulations, functional foods, and dietary supplement development. Before use, manufacturers should verify its fatty acid profile, purity, stability, and suitability for the intended product category.

Capsules, Oral Liquids, and Protein Powders

Manufacturers developing capsules, oral liquid products, and protein powders may assess the ingredient during raw material selection. Compatibility with other ingredients, formulation stability, and the relevant quality requirements should be established through appropriate testing.

Shampoo and Conditioner Formulations

The oil-based ingredient may be considered for selected shampoo and conditioner formulations. Formulators should evaluate its compatibility with the product base, oxidation stability, sensory properties, and finished-product safety.

Coatings and Chemical Applications

The product is also listed for potential use in coatings and chemical processing. Its suitability for these applications should be assessed based on chemical composition, compatibility with other materials, and performance under the intended processing conditions.

Rubber and Other Industrial Uses

For rubber-related and other industrial applications, the material may be evaluated where its verified properties meet the requirements of the target formulation or manufacturing process.

Medical-Related Applications

Medical-related uses require additional assessment of identity, purity, safety, intended use, and applicable regulatory requirements. The inclusion of this application category does not establish medical-grade status or approval for a particular medical use.

Quality Control and Raw Material Evaluation

When sourcing specialized oil-based ingredients, manufacturers should evaluate the material using documented specifications and appropriate analytical methods.

• Composition Verification: Confirm the identity and content of ethyl alpha-linolenate through an agreed analytical method.

• Oxidation Quality: Review the peroxide value and any additional oxidation indicators required for the intended application.

• Purity Assessment: Check moisture, insoluble impurities, residual solvents, and applicable heavy metal limits.

• Microbiological Testing: Verify microbial results against the relevant product category and customer requirements.

• Batch Consistency: Request a batch-specific COA and confirm that the supplied material meets the agreed specifications.

Additional testing may be required for food, dietary supplement, cosmetic, or industrial applications. Buyers should establish acceptance criteria before placing bulk orders.

Packaging, Shelf Life, and Storage

The standard package is a 25 kg plastic drum, with alternative packaging options available upon request.

The stated shelf life is 12 months when the product remains unopened. Store it in a cool, dry place at room temperature and protect it from excessive heat.

After opening, follow the supplier's handling instructions and maintain appropriate packaging integrity to help minimize contamination and oxidation. For extended storage or international transportation, confirm suitable packaging and handling conditions with the supplier.
