Introduction
Beta-Carotene Oil Suspension (CAS: 7235-40-7) is a reddish-brown, viscous liquid containing micronized Beta-Carotene crystals dispersed in a vegetable oil carrier (Sunflower, Corn, or Olive Oil).
As a potent Pro-Vitamin A and natural antioxidant, it is a staple ingredient in the nutraceutical industry. Our 30% Oil Suspension is specifically engineered to solve the common issues of sedimentation and oxidation. The beta-carotene particles are milled to <5 microns, ensuring a smooth suspension that provides uniform color and precise dosage for softgel manufacturing and oil-based food applications (e.g., margarine, sauces).

Functions
1.Pro-Vitamin A Activity (Vision & Immunity)
Beta-Carotene is safely converted into Vitamin A (Retinol) by the body only as needed. It supports low-light vision, healthy mucous membranes, and robust immune function without the toxicity risk associated with preformed Vitamin A.
2.Potent Antioxidant Defense
It acts as a powerful singlet oxygen quencher, protecting cells from oxidative stress and UV-induced damage. This makes it a popular ingredient in "Suncare from Within" supplements.
3.Natural Coloration
Provides a vibrant yellow-to-orange hue to oil-based products. Unlike artificial dyes (like Yellow No. 5), it offers a clean-label coloring solution that consumers trust.
Applications
1.Softgel Capsules (Main Application)
• Format: Single ingredient or Multivitamin Softgels.
• Why: Our 30% OS flows smoothly through encapsulation dies, ensuring accurate fill weights and consistent active content per capsule.
2.Oil-Based Foods
• Products: Margarine, Butter, Salad Dressings, Popcorn Oil.
• Benefit: Provides standard "buttery" color and Vitamin A fortification.
3.Cosmetic Oils
• Products: Body Oils, Tanning Oils.
• Benefit: Adds a golden glow to the skin and provides antioxidant protection.
Flow Chart
Micronization Technology for Suspension Stability
1.Crystal Preparation: Beta-Carotene crystals (Synthesis or Fermentation from Blakeslea trispora).
2.Milling: Wet grinding (Ball mill) to reduce particle size to <5 μm.
3.Dispersion: Homogenizing the micronized crystals into the Oil Carrier (Sunflower/Corn Oil).
4.Stabilization: Addition of Antioxidants (dl-alpha-Tocopherol) to protect the double bonds.
5.Heat Treatment: Controlled heating to ensure crystal stability.
6.Deaeration: Removing air bubbles to prevent oxidation.
7.Filtration: Removing any coarse particles.
8.QC Testing: HPLC Assay & Peroxide Value.
9.Packaging: Nitrogen-flushed Aluminum or PE Drums.

Method of Analysis of Lactoferrin
Spectrophotometry & HPLC
• Spectrophotometry (UV-Vis): Used for routine color intensity checks.
• HPLC: The definitive method for quantifying Beta-Carotene content and separating it from other carotenoid isomers (Alpha-carotene) or degradation products.
Reference Chromatogram of Lactoferrin Reference Substance
(Visual Placeholder: HPLC Chromatogram)
The chromatogram displays a dominant peak for all-trans-Beta-Carotene, confirming the high potency and low levels of cis-isomers, which ensures maximum bioavailability.
Stability and Safety
Stability Studies
• Challenge: Beta-Carotene is extremely sensitive to light and oxygen.
• Our Solution: Our suspension is stabilized with Tocopherols and packed under Nitrogen.
• Shelf Life: 24 months when stored in original unopened containers at <25°C.
• Note: Once opened, use immediately or blanket with nitrogen before resealing.
Safety & Handling (MSDS Summary)
• Classification: Non-hazardous.
• Handling: Product stains heavily! Wear protective clothing and gloves. Spills are difficult to clean; use vegetable oil to solubilize, then detergent.
• Storage: Store in a cool, dry place. Protect from sunshine.

FAQ
What is the difference between Natural and Synthetic Beta-Carotene?
• Synthetic: Chemically identical to nature, cost-effective, high purity. Best for standard supplements. • Natural: Fermented from Blakeslea trispora or extracted from Dunaliella salina. Preferred for "Clean Label" or "Natural Source" claims. We supply both.
Does the oil suspension separate over time?
Minor sedimentation may occur over long storage periods. This is normal. We recommend stirring or shaking the drum before use to ensure homogeneity.
How much Beta-Carotene equals 1 IU of Vitamin A?
Generally, 0.6mcg(μg) Beta-Carotene = 1 IU Vitamin A activity. (Calculation varies slightly by regulation: FDA vs. EFSA).
