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

Product Overview

Silkworm Pupa Oil Ethyl Alpha-Linolenate is an oil-based ingredient derived from silkworm pupae oil through extraction and refining processes. Identified in the supplied product specification as an omega-3 fatty acid derivative, this ingredient is intended for manufacturers seeking specialized lipid-based raw materials for nutritional, personal care, and selected industrial applications.

With a specified ethyl alpha-linolenate content of at least 40%, the product is supplied as a yellowish to yellow, clear, transparent oily liquid. Its quality specifications cover appearance, transparency, moisture and volatile substances, insoluble impurities, peroxide value, residual solvents, heavy metals, and microbiological indicators.

Available in 25 kg plastic drums, the product can also be packaged according to customer requirements. It is suitable for B2B sourcing and further evaluation by manufacturers developing formulations or processing products in relevant application sectors.

Key Product Features

1. Silkworm Pupa Oil-Derived Raw Material

The product uses silkworm pupa oil as its stated raw material source. The extraction and refining process produces an oil-based ingredient for further formulation and processing.

2. Defined Active Ingredient Content

The internal quality specification sets the ethyl alpha-linolenate content at a minimum of 40%. This provides a reference point for buyers evaluating raw material composition and formulation requirements. The analytical method and the identity of the measured compound should be confirmed with the supplier before purchase.

3. Clear Oily Liquid Appearance

The finished material is specified as a yellowish or yellow clear, transparent oily liquid, with transparency required at 20°C. These appearance requirements provide basic quality criteria for incoming material inspection.

4. Quality and Purity Specifications

The product specification includes limits for moisture and volatile substances, insoluble impurities, peroxide value, residual solvents, selected heavy metals, and microbial counts. These indicators help buyers evaluate material quality and determine whether the product meets their intended manufacturing requirements.

5. Flexible Packaging Options

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

Product Specifications

The values above are based on the supplied internal product specification. Buyers should request the current technical data sheet, certificate of analysis (COA), applicable test methods, and batch-specific documentation when evaluating the material.

Potential Applications

Silkworm Pupa Oil Ethyl Alpha-Linolenate is listed for use in several product and industrial sectors. Its suitability for each application depends on the formulation, regulatory requirements, and verified material characteristics.

Nutritional Products and Functional Foods

The ingredient may be evaluated as a lipid-based raw material for nutritional formulations, health food products, and dietary supplement development. Manufacturers should confirm its fatty acid profile, intended-use suitability, purity requirements, and applicable food or supplement regulations before incorporating it into products.

Capsules, Oral Liquids, and Protein Powders

For manufacturers developing capsules, oral liquid formulations, and protein powder products, the ingredient may be considered during raw material screening. Compatibility, dosage formulation, stability, and product-specific regulatory requirements should be assessed before use.

Shampoo and Conditioner Formulations

The oil-based material may be evaluated for selected personal care formulations, including shampoos and conditioners. Formulation compatibility, oxidation stability, sensory properties, and finished-product safety should be established through appropriate testing.

Coatings and Chemical Processing

The product is also listed for consideration in coatings and chemical industry applications. Buyers should evaluate its chemical composition, compatibility with other ingredients, and performance under the intended processing conditions.

Rubber and Other Industrial Uses

For rubber-related and other industrial applications, the material may be assessed as a candidate ingredient where its verified chemical characteristics meet the technical requirements of the formulation or manufacturing process.

Medical-Related Applications

Use in medical products requires separate assessment of material identity, purity, safety, intended use, and applicable regulatory standards. The listed application category should not be interpreted as confirmation of medical-grade status or approval for a specific medical use.

Quality Control and Material Evaluation

Reliable raw material selection requires more than appearance and a stated ingredient percentage. For procurement and formulation development, buyers should review the following quality indicators:

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

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

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

• Microbiological Quality: Verify microbial test results against the relevant product and application standards.

• Batch Consistency: Request a COA for the supplied batch and clarify the applicable internal or customer-approved specifications.

Additional testing may be required depending on whether the material is intended for food, dietary supplements, cosmetics, chemical processing, or other industrial uses.

Packaging, Shelf Life, and Storage

The standard packaging format is a 25 kg plastic drum, with alternative packaging arrangements available for discussion according to customer requirements.

The stated shelf life is 12 months when the product remains unopened. Store the material in a cool, dry place at room temperature and protect it from elevated temperatures. After opening, follow the supplier's handling instructions and maintain appropriate packaging integrity to help minimize contamination and oxidation.

For long-distance transportation or extended storage, buyers should confirm suitable packaging, sealing, and storage conditions with the supplier.
