How to Make Stick Balms
Lip Balm, Solid Lotion Bars & Push-Up Tubes
Lip balm is an anhydrous (water-free) product designed to moisturize, protect, and condition the lips. Made from a blend of waxes, butters, and oils, lip balm creates a protective barrier while delivering emollient benefits to keep lips soft and hydrated.
Because lip balm contains no water, it doesn't require traditional preservatives. However, antioxidants are recommended to prevent oils from going rancid. Formulating the perfect stick requires balancing hardness for stability with a low enough melt point to glide onto the skin effortlessly.
Formula Structure
| Component | Purpose | Typical % |
|---|---|---|
| Waxes | Creates stick structure | 15-25% |
| Butters | Richness and moisture | 15-35% |
| Liquid Oils | Slip and absorption | 40-70% |
| Castor Oil | Gloss and adhesion | 5-15% |
Safety & Workspace
Ingredient Safety & Oxidation
Use only ingredients verified as lip-safe. While traditional preservatives aren't needed for anhydrous sticks, an antioxidant is critical for preventing oil rancidity. BalmMath calculates the type and amount needed for your specific oil blend — T50, T95, rosemary oleoresin (ROE), or BHT.
Sanitation: Sanitize all equipment and containers with 70% isopropyl alcohol before use. Ensure your workspace is free of dust and contaminants.

Key Ingredient Guide
Waxes (15-25%)

- Candelilla Wax: Vegan alternative, slightly harder than beeswax
- Carnauba Wax: Very hard, use at 1-3% for heat resistance
Butters (15-35%)
- Shea Butter: Moisturizing, creamy texture
- Cocoa Butter: Adds hardness and natural chocolate scent
- Mango Butter: Light, non-greasy emollient
Liquid Oils (40-70%)
- Sweet Almond Oil: Light, moisturizing base
- Jojoba Oil: Liquid wax that mimics skin's sebum

Formulate with BalmMath
Select Stick Balm Type
This ensures the hardness meter targets the firm 15-25% wax range required for tubes.Add Structuring Agents
Input your beeswax or candelilla. Watch the hardness meter climb as you add wax.Choose Emollients
Add your butters and liquid oils. Use 5-15% castor oil for the best lip adhesion.Review Hardness
Ensure the hardness meter lands in the green zone. If it's too soft, the balm will melt in a pocket.Manufacturing Steps
Melt Waxes & Hard Butters
Combine beeswax and cocoa butter in a double boiler. Heat to 180-190°F (82-88°C) until fully liquid.Add Liquid Oils
Stir in your liquid carrier oils and castor oil. The temperature will drop as you add the cooler oils.Cool to Additive Temp
Remove from heat. Wait until the mixture reaches 140-150°F (60-66°C).Add Fragrance & Antioxidant
Stir in your lip-safe flavor oil and antioxidant (BalmMath calculates the type and amount for your specific oil blend). Stir gently to avoid bubbles.Pour Quickly
Pour into tubes while the mixture is still very liquid. If it starts to set in the pot, gently reheat.Cool Completely
Allow tubes to set undisturbed at room temperature for at least 2 hours before capping.Pro Tip
Troubleshooting
| If… | Then… | Solution |
|---|---|---|
| Balm is soft/melts in pocket | Too little wax or too much oil | Increase wax to 25%; use cocoa butter |
| Gritty/grainy texture | Shea/cocoa cooled too slowly | Cool quickly in fridge after pouring |
| Shrinkage/hole in center | Poured too hot | Pour at ~145°F; perform top-off pour |
| Does not glide/drags skin | Too much wax or carnauba | Reduce wax; increase liquid oils |
| Tops are rough/bumpy | Sets too fast during pour | Use a heat gun briefly on the tops to smooth |
Lip Safety Considerations
Important: Lip products require special consideration
- Only use FDA-approved lip-safe colorants
- Use only lip-safe, flavor-grade fragrances
- Many essential oils are not safe for lip application
- Test all ingredients for lip-safe status before using
SPF Lip Balm Is an OTC Drug — Not a Cosmetic
The moment you add an SPF claim or any sun protection claim to a lip balm, it becomes an OTC drug regulated under FDA's Sunscreen Monograph (M020). This means it requires a full Drug Facts label, must use only FDA-approved active ingredients at monograph concentrations, and must be manufactured under pharmaceutical-grade GMPs. A homemade zinc oxide lip balm cannot be legally labeled or sold with an SPF claim.
