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%)

Beeswax: Classic choice, creates protective barrier, slightly tacky
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
Castor Oil: Essential for high gloss and adhesion to lips

Example Formulas

Classic Beeswax Lip Balm

Beeswax 25%, Shea Butter 25%, Sweet Almond Oil 40%, Castor Oil 10%

Vegan Mango Gloss Stick

Candelilla Wax 18%, Mango Butter 20%, Jojoba Oil 47%, Castor Oil 15%

Hard Summer-Proof Balm

Beeswax 20%, Carnauba Wax 3%, Cocoa Butter 25%, Fractionated Coconut Oil 52%

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

Pro Tip: Avoiding "The Sinkhole" — As lip balm cools, it contracts, often creating a hole or dip in the center of the tube. To prevent this, pour at the lowest possible temperature that still flows (around 145°F / 63°C). You can also do a "top-off" pour: fill the tubes 95% full, let them set for 5 minutes, then fill the remaining 5% to create a smooth, domed top.

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.
