Description

Soybean Oil, Nonsaponifiable Fraction is a specialized lipid extract derived from soybean oil, consisting of the components that do not form soaps upon alkaline hydrolysis. This CAS NO 91770-67-1 material is valued for its rich content of bioactive compounds, including sterols, tocopherols, and hydrocarbons. It serves as a critical raw material and functional ingredient for manufacturers in the nutraceutical, cosmetic, and specialty chemical industries seeking natural, lipid-based actives.

Application

• Nutraceutical & Dietary Supplements: As a source of plant sterols (phytosterols) and vitamin E (tocopherols) for cholesterol-management and antioxidant formulations.
• Cosmetics & Personal Care: Incorporated into skincare products like creams, lotions, and serums for its emollient properties and skin-barrier enhancing benefits.
• Pharmaceutical Excipients: Used in the development of topical ointments, creams, and as a carrier for lipophilic active pharmaceutical ingredients (APIs).
• Functional Food & Beverage Fortification: As a natural additive to enhance the nutritional profile of foods with plant-based sterols and tocopherols.
• Industrial Biotechnology: Acts as a substrate or additive in fermentation processes and enzymatic reactions.
• Research & Development: Serves as a standard or raw material in analytical laboratories and for developing new lipid-based products.

Quality Control

Our Soybean Oil, Nonsaponifiable Fraction is produced and controlled under a strict quality management system. Each batch is analyzed to ensure consistency and meets specifications for key markers such as sterol and tocopherol content. Certificates of Analysis (COA) detailing purity, composition, and relevant tests are provided to guarantee compliance with customer requirements and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 15-25°C (59-77°F). This material is easily oxidized; for long-term storage, filling the container headspace with an inert gas (e.g., nitrogen or argon) is recommended to maintain stability.
