Melting point decision tree
Choose the right wax–butter–oil ratios based on firmness, climate, and sensory goals.
START HERE: What texture do you want?
1. Do you want a soft, scoopable product?
(salve, soft balm, night balm)
→ YES → Go to Section A
→ NO → Continue
2. Do you want a medium‑firm balm?
(lip balm, solid perfume, protective balm)
→ YES → Go to Section B
→ NO → Continue
3. Do you want a solid bar?
(lotion bar, massage bar, travel bar)
→ YES → Go to Section C
→ NO → Continue
4. Do you want a whipped butter?
(fluffy, airy, melts on contact)
→ YES → Go to Section D
→ NO → End (choose closest category)
SECTION A — Soft, Scoopable Products
Target: Low melting point, creamy, semi‑solid
Ideal Butters:
- Shea
- Mango
- Cupuaçu
Ideal Oils:
- Sunflower
- Jojoba
- Rosehip
Wax Ratio:
- 0–5% wax (optional)
If too soft:
→ Add 2–5% beeswax or switch to mango butter
If too firm:
→ Add more liquid oil
If grainy:
→ Cool rapidly (fridge) or blend in mango butter
SECTION B — Medium‑Firm Balms
Target: Holds shape but melts on contact
Ideal Butters:
- Shea
- Mango
- Cocoa (for firmness)
Ideal Oils:
- Jojoba
- Sunflower
- Coconut (firms formula)
Wax Ratio:
- 10–20% wax
If too soft:
→ Increase wax by 5% or add cocoa butter
If too hard:
→ Add more liquid oil or replace cocoa with mango
If melting in warm climates:
→ Add 2–5% carnauba or candelilla wax
SECTION C — Solid Bars (High Melting Point)
Target: Firm, portable, heat‑resistant
Ideal Butters:
- Cocoa
- Kokum
- Mango (secondary)
Ideal Oils:
- Jojoba
- Coconut
- Olive (sparingly)
Wax Ratio:
- 20–33% wax
If bar is too soft:
→ Add more cocoa/kokum or increase wax
If bar is too brittle:
→ Add shea or jojoba to soften
If bar melts in summer:
→ Add carnauba (1–3%) for heat stability
SECTION D — Whipped Butters
Target: Fluffy, airy, melts instantly
Ideal Butters:
- Shea
- Mango
- Cupuaçu
Ideal Oils:
- Sunflower
- Jojoba
- Rosehip
Wax Ratio:
- 0% wax (avoid wax — it ruins the whip)
If too melty:
→ Add mango butter or a tiny amount of cocoa butter (5–10%)
If too heavy:
→ Increase sunflower or rosehip oil
If grainy:
→ Melt fully → cool quickly → whip at semi‑solid stage
Melting Point Logic (Quick Reference)
| Ingredient | Melting Point | Effect on Formula |
|---|---|---|
| Cocoa Butter | High | Firms, stabilizes, adds structure |
| Kokum Butter | Very high | Creates solid bars, prevents melting |
| Shea Butter | Medium | Soft, creamy, prone to graininess |
| Mango Butter | Medium‑low | Light, silky, prevents graininess |
| Cupuaçu Butter | Medium‑low | Hydrating, cushiony, softens blends |
| Beeswax | High | Firms, stabilizes, adds occlusion |
| Candelilla/Carnauba | Very high | Heat‑proofs formulas |
🧪 Troubleshooting via Melting Point
Product melts in warm weather
→ Add cocoa/kokum butter
→ Increase wax
→ Add carnauba (1–3%)
Product is too hard
→ Reduce wax
→ Add shea or liquid oil
Product is too soft
→ Add cocoa/kokum
→ Increase wax by 5–10%
Product feels greasy
→ Add mango butter
→ Reduce high‑oleic oils (olive, avocado)
Product is grainy
→ Rapid cooling
→ Add mango butter
→ Avoid slow cooling of shea
Ratio‑adjustment
How to adjust wax–butter–oil ratios for texture, climate, and sensory goals.
1. Core Ratio Matrix (Base Starting Points)
| Product Type | Wax % | Butter % | Oil % | Texture Target |
|---|---|---|---|---|
| Soft Salve | 0–5% | 20–40% | 55–80% | Scoopable, semi‑solid |
| Medium Balm | 10–20% | 20–40% | 40–60% | Holds shape, melts on contact |
| Firm Balm | 20–25% | 20–30% | 45–55% | Lip balm / solid perfume |
| Lotion Bar | 25–33% | 25–33% | 33–50% | Solid, portable |
| Whipped Butter | 0% | 60–80% | 20–40% | Fluffy, airy, melt‑on‑skin |
2. Ratio Adjustment Matrix (What to Change When…)
A. If the product is TOO SOFT
| Adjustment | How Much | Why It Works |
|---|---|---|
| Increase wax | +5–10% | Raises melting point + firmness |
| Add cocoa or kokum butter | +5–15% | High‑melting butters add structure |
| Reduce liquid oil | –5–15% | Less fluidity = more solidity |
B. If the product is TOO HARD
| Adjustment | How Much | Why It Works |
|---|---|---|
| Reduce wax | –5–10% | Softens texture immediately |
| Add shea or mango butter | +10–20% | Soft, creamy butters loosen structure |
| Add liquid oil | +5–15% | Increases spreadability |
C. If the product MELTS in warm weather
| Adjustment | How Much | Why It Works |
|---|---|---|
| Add carnauba/candelilla wax | +1–3% | Very high melting point |
| Add cocoa or kokum butter | +10–20% | Heat‑stable butters |
| Reduce shea/cupuaçu | –10–20% | Lower melting point butters soften too easily |
D. If the product feels TOO GREASY
| Adjustment | How Much | Why It Works |
|---|---|---|
| Add mango butter | +10–20% | Light, dry‑touch butter |
| Reduce olive/avocado oil | –10–20% | High‑oleic oils = heavy feel |
| Increase wax slightly | +2–5% | Adds structure + reduces slip |
E. If the product feels TOO WAXY or DRAGGY
| Adjustment | How Much | Why It Works |
|---|---|---|
| Reduce wax | –5–10% | Less drag |
| Add liquid oil | +5–15% | Improves glide |
| Add cupuaçu or mango butter | +10–20% | Adds slip + cushion |
F. If the product is GRAINY
| Adjustment | How Much | Why It Works |
|---|---|---|
| Add mango butter | +10–20% | Prevents crystallization |
| Rapid‑cool the batch | n/a | Stops shea from forming crystals |
| Reduce shea butter | –10–20% | Shea is prone to graininess |
3. Ratio Logic by Ingredient Type

| Cocoa | Hard, stable | Bars + firm balms |
| Kokum | Very firm | High‑structure bars |
| Cupuaçu | Hydrating, cushiony | Luxurious, soft textures |
Oils
| Oil | Effect | Use When |
|---|---|---|
