Top Fraction, PC enriched
The top part, becomes our PC enriched product which is high in active phospholipids like PC, and PI. This specific fraction has stronger emulsifying and dispersing properties, especially in water-based systems.

Discover the Science Behind Fractionated Lecithin
Learn how fractionated lecithin improves formulations in food, cosmetics, and nutraceuticals.
The Process
What Is Fractionated Lecithin?
Fractionated lecithin is a phospholipid profile modified form with standard natural lecithin as start material this can be based on Sunflower, Soybean or Rapeseed as origin. Standard lecithin is a mix of phospholipids, triglycerides, glycolipids, and other minor compounds. It works well as a natural emulsifier. In our fractionation process separates lecithin into two parts:
At SD Guthrie International Specialty Ingredients, we produce quality fractionated lecithin. We separate this into top (PC enriched) and PE-rich (PC depleted) Fractions. Both have specific roles in formulations, such as improved performance, clarity, and stability.
PE-rich Fraction
The other more PE-rich fraction part, contains less polar phospholipids, tends to be more oil soluble and better usable in high fat applications.
Why It Helps
General Benefits of Using Fractionated Lecithin
- Enhanced emulsion stability
- Improved mouthfeel in food and beverages
- Increased dispersibility in powders
- Boosted bioavailability in nutraceuticals
- Clean label options with non-GMO sunflower lecithin

Composition
Key Differences Between Top and Concentrated Fraction
| Phospholipid Type | PE and PI Concentrated Fraction (%) | Top Fraction (PC enriched) (%) |
|---|---|---|
| Phosphatidylcholine (PC) | 2 - 10% | 20 - 35% |
| Phosphatidylethanolamine (PE) | < 5% | 15 - 25% |
| Phosphatidylinositol (PI) | < 3% | 10 - 20% |
- Top Fraction (PC enriched): Light in color, oil-like, and low in odor. Used in cosmetic oils, softgels, and premium lipid systems.
- PE and PI Concentrated Fraction: Emulsifier-rich and functionally active. Ideal for beverages, supplements, and dispersions.
Behaviour
How Do These Fractions Behave Differently?
PE and PI Concentrated Fraction
The PE and PI Concentrated Fraction contains more lipophilic (oil-loving) substances. This means it blends seamlessly into fats and oils without introducing cloudiness or instability. It behaves more like a neutral lipid than a functional emulsifier. This makes it perfect for:
- Creating clear oil-based solutions. For example, in a cosmetic face oil, the top fraction dissolves 100% into the base oils without cloudiness. This gives the product a crystal-clear appearance.
- Reducing unwanted flavor or odor interference. For instance, in a nutritional oil blend, the top fraction contributes minimal taste and smell. This preserves the product's clean sensory profile.
- Enhancing lipid texture without over-thickening. For example, in a softgel capsule, the top fraction improves the smoothness. Also, it helps the consistency of the fill material without increasing viscosity.
- Offering subtle functional effects: it modifies texture and miscibility. But it doesn't drive emulsification or hydration on its own. For instance, in a body oil, it helps mix different oils together smoothly without using an emulsifier. So the final product still feels and looks like a pure oil without any creaminess or thickness.
Top Fraction (PC enriched)
The Top Fraction (PC enriched) is highly amphiphilic (both water- and oil-attracted). Which gives it powerful emulsifying and dispersing properties. It behaves like an active agent in systems where stabilization, hydration, or bioavailability is needed. It tends to:
- Bind water and oil phases effectively. For instance, in a dairy-free creamer, this fraction ensures that the oil and water stay blended. This prevents separation and delivers a fluid, uniform product every time.
- Improve suspension of particles in liquids. An example is the use in a powdered beverage mix. The lecithin helps keep cocoa or protein particles evenly distributed in the drink. This prevents them from settling at the bottom.
- Deliver phospholipid-related health or performance benefits. For instance, in a dietary supplement, lecithin provides phosphatidylcholine. This supports brain and liver health. So, it's a functional ingredient with physiological benefits beyond formulation.
- Produce a stronger functional effect: it plays a more active role by helping to mix ingredients. This keeps the mix stable and shapes how the final product feels and performs. For example, in a ready-to-drink protein shake, the lecithin helps prevent sedimentation. But also it keeps the protein evenly distributed. This gives the drink a smoother, creamier texture throughout its shelf life.

Pricing
Why Is the Top Fraction More Expensive?
- Low Yield: Only 15-30% of crude lecithin becomes top fraction. That means you need a lot of raw material to produce a small amount of usable product.
- High Purity Requirements: The top fraction must be light in color, low in odor, and chemically stable. Especially for sensitive applications like cosmetics or nutraceuticals. Achieving this level of refinement adds cost.
- Complex Processing: Fractionation isn't simple. It involves:
- Solvent extraction
- Careful phase separation
- Additional quality checks and thoroughly analytical testing during production
- Solvent recovery and drying under vacuum. Each step adds time, equipment use, and energy.
- Specialized Demand: The top fraction is used in high-end or niche formulations. Performance and appearance play a valuable role. It's a specialty product, not a commodity, and that’s reflected in the price. Ideal for oil-based systems like cosmetic serums, nutritional oils, or flavor carriers. In these products, cloudiness or odor is often a problem.
