How does the blend melting point helper estimate the melting point of a shea and cocoa butter mix?

It takes a mass-weighted average of each component's slip-point range. A 60/40 shea–cocoa mix with shea at 32–45 °C and cocoa at 31–35 °C estimates 31.6–41.0 °C. That is a first approximation and a range, not a specification.

Why can a real shea butter blend melt lower than the blend melting point helper predicts?

Mixed triglycerides are not ideal solutions. Stearic–oleic-rich fats (shea, cocoa, kokum) can form eutectic minima, so a blend may melt below both components. Shea is polymorphic and its slip point drifts with tempering and storage. Confirm the finished blend by AOCS Cc 3-25.

Which slip melting point does the blend helper use for shea butter?

The same published literature ranges as the melting-point specification page: 32–45 °C for unrefined Grade A, and an indicative 32–40 °C for refined N-RBD. For your batch, choose Custom and enter the slip point from the Certificate of Analysis.

Can I add beeswax or liquid oils to the blend melting point helper?

Yes. Beeswax, candelilla, sunflower, sweet almond, jojoba and castor are included with literature slip or pour points. The helper lowers its confidence when liquid oil exceeds 30 % or wax exceeds 10 %, because the linear model is weakest there.

How should I confirm the blend helper's estimate in the laboratory?

Make the blend, temper it as you will in production, run slip melting point by AOCS Cc 3-25 (open capillary) in duplicate, and repeat after one to two weeks of storage to catch polymorphic drift. The test-methods directory lists the method.

Stearic–oleic-rich butters can form eutectics; the real slip point may fall below the estimate.

First approximation only. Real blends deviate because of eutectic effects and polymorphism — confirm by AOCS Cc 3-25.

How the estimate works

Shares are normalised: wᵢ = %ᵢ ÷ Σ %. The tool warns if the total is not 100 and shows the normalised shares. The estimated range is MP_low = Σ wᵢ × MPᵢ,low and MP_high = Σ wᵢ × MPᵢ,high; the midpoint is reported too. The helper estimates a blend's slip melting point as the mass-weighted average of each component's slip-point range — a first approximation that ignores eutectic effects and polymorphism, which is why it reports a range and asks you to confirm by AOCS Cc 3-25.

Hardness is an indicator, not a measurement: hard share is the sum of weights for components whose lower slip point is above 30 °C. At 70 % or more the label is “firm at room temperature”; 40–70 % is “soft solid”; below 40 % is “semi-liquid at 25 °C”.

Triglyceride mixtures are not ideal solutions. Stearic–oleic-rich fats (shea, cocoa, kokum) show eutectic minima at some ratios, so a blend can melt below both components. Shea butter is polymorphic and its slip point drifts with tempering and storage. Waxes and liquid oils are chemically different (wax esters, unsaturated triglycerides) and the linear model is least reliable when they exceed roughly 30 % of the blend — the helper then marks the result low-confidence.

Single-material shea values live on the melting-point specification. The definition is in the slip melting point glossary. If the blend is for soap, use the lye calculator. Check the slip point on a shea COA with the COA interpreter.

Worked example

Sixty per cent unrefined shea (32–45 °C) plus 40 % cocoa butter (31–35 °C): MP_low = 0.6 × 32 + 0.4 × 31 = 31.6 °C; MP_high = 0.6 × 45 + 0.4 × 35 = 41.0 °C; midpoint 36.3 °C; hard share 100 % → firm. Published work on shea–cocoa blends shows softening at intermediate ratios, so the real slip point may sit below this range; run AOCS Cc 3-25 on the actual blend. See shea butter compared with cocoa butter.

Assumptions and limits

The model is linear mixing of literature ranges. Batch values vary — use the COA slip point for your shea via Custom. Slip point is not complete melt point and is not drop point. The helper does not model tempering or cooling rate, and it is not for emulsions or products with water. Waxes raise the feel of firmness more than the slip point suggests. Liquid oils above about 30 % are flagged as low confidence. There is no safety or regulatory content — this is a texture screen.

What your estimate means for a shea formulation

Indicative targets from formulation texts: a lip balm is typically built to hold shape above body-heat handling (a low end well above 40 °C); a body butter should stay firm at 25–30 °C storage but spread on skin; cocoa-butter-equivalent work needs cocoa-butter-compatible melting — see the CBE glossary. Because the model is linear, shifting mass from the lowest-melting to the highest-melting component raises the midpoint by a predictable amount; the helper prints the percentage points per degree when you enter a target.

Unrefined Grade A and refined N-RBD slip ranges differ; choose the shea you will actually buy on the Grade A product page or refined N-RBD. Always confirm with a slip-point test on the actual blend — AOCS Cc 3-25.
