Illipe Butter

Overview

Illipe butter (also sometimes called Borneo tallow) comes from the nuts of the Shorea stenoptera tree, native to the rainforests of Borneo and Southeast Asia. The fat is extracted from the large, oily seeds that drop from the tree during fruiting season — traditionally collected from the forest floor by indigenous communities.

The refined butter is pale yellow to white, firm at room temperature, with a mild nutty scent that disappears in formulation. Its melting point (34-38 C) is nearly identical to cocoa butter, but the crystal structure is slightly different — illipe butter sets to a smoother, less brittle solid and is less prone to the grainy crystallization (bloom) that plagues cocoa butter.

The fatty acid profile tells the story: roughly 45% stearic acid, 35% oleic acid, and 15% palmitic acid. This high stearic + oleic combination means firm structure plus good skin absorption — it melts readily on contact with skin and absorbs without leaving a waxy residue. For DIY formulators, illipe is the “better-behaved cocoa butter” — similar hardness, easier to work with, less finicky about tempering.

What it does in a formula

Illipe butter functions as:

1. Structural hardener — provides bar firmness in lip balms, lotion bars, and solid products. Similar firmness to cocoa butter but with less brittleness.
2. Emollient barrier former — melts at body temperature and forms a smooth, protective film. The high oleic acid content means it absorbs well rather than sitting on the surface.
3. Cocoa butter substitute (CBS) — the food industry uses illipe as a CBS in chocolate, and the same logic applies to cosmetics. Anywhere cocoa butter goes, illipe can follow — with less tempering headache and no chocolate scent.

The smoothness of illipe’s crystal structure makes it particularly good for lip products where a silky, non-grainy texture is essential.

How to use

• In lip balms: 20-50%. Gives firm structure with a smooth, creamy melt. Less prone to graininess than cocoa butter.
• In body balms and bars: 25-60%. Combines well with shea butter (softness) and a liquid oil (slip).
• In lotions and creams: 5-15% in the oil phase for body, barrier repair, and a slight thickening effect.
• In hair products: 5-20% in deep conditioner bars or hair butter blends. Smooths the cuticle without heavy buildup.
• Melting: Gentle heat, 40-45 C. Like all high-stearic butters, avoid overheating to reduce crystallization issues.
• Blending with cocoa butter: A 50/50 blend of illipe and cocoa butter gives cocoa butter’s firmness with much better bloom resistance.
• Solo use: Can be used at 100% as a simple body bar or lip balm — just melt and pour.

Best for / Worst for

Best for: lip balms, lotion bars, body balms, hair butters, cocoa butter replacement, solid perfume bases, products where graininess is unacceptable, tropical-climate-stable formulas.

Worst for: lightweight facial moisturizers (too heavy), whipped products at high percentages (can feel draggy), very cold climates where the bar needs to stay soft enough to apply (consider softer butters), products requiring a completely liquid oil phase.

Common pitfalls

Assuming identical behaviour to cocoa butter. While similar, illipe is slightly softer and has a slightly lower melting point. If a recipe relies on cocoa butter’s specific snap-and-melt (like in chocolate-style lip products), you may need to add 5-10% more illipe or blend with a harder wax.

Overheating. Heating above 60 C for extended periods can cause odd crystallization on cooling. Melt gently and cool steadily.

Sourcing confusion. “Illipe butter” sometimes refers to Madhuca latifolia (Indian mahua butter) in older references. For cosmetics, look for the INCI Shorea Stenoptera Seed Butter — that’s the Borneo illipe.

Using in hot-climate balms without adjustment. Illipe melts at ~35-37 C. In tropical climates, products stored in purses or cars may soften. Add a small amount of beeswax or candelilla wax (2-5%) for heat stability if needed.

Substitutes

• Cocoa butter — firmer, more brittle, stronger scent, more prone to bloom.
• Sal butter — very similar profile, slightly harder.
• Kokum butter — harder, drier feel, higher melting point.
• Mango butter — softer, more spreadable, less structural.
• Shea butter — much softer, creamy rather than firm, different role in formulas.
