Balm Recipe Formulations

Rose approached me several weeks ago regarding a balm she wished to create.

The intended recipient was suffering from an irritation affecting the hands and forearms. Various treatments had been attempted without success, and Rose had begun investigating botanical alternatives.

I agreed to assist, primarily because the project was interesting.

The objective appeared straightforward enough: A balm should remain solid while stored, yet soften readily when applied to the skin. Achieving both characteristics simultaneously requires a careful balance of ingredients. I began by examining the melting points of the proposed materials:

Coconut Oil: 78°F

Castor Oil: 14°F

Sweet Almond Oil: 14°F

Cocoa Butter: 93°F

Beeswax: 144°F

While reviewing these figures, I developed a hypothesis.

If each ingredient contributes to the final product according to both its proportion and its individual melting point, it should be possible to estimate the melting point of an entire formulation before ever producing it. At least in theory.

Six experimental formulations were prepared.

Each varied the percentages of beeswax, cocoa butter, and liquid oils while maintaining the same overall ingredient selection.

NA-##	CCNT %	CAST %	SWAO %	CCBTTER %	BWAX %	Predicted MP (F)
AP-01	55	7.5	7.5	20	10	84
BA-01	60	8.5	8.5	15	8	80
LB-01	50	6.5	6.5	25	12	89
AP-02	57	7.5	7.5	18	10	83
BA-02	58	8	8	17	9	89
LB-02	52	6.5	6.5	22	13	81

The calculated melting point of each formulation was recorded prior to production. The actual behavior of each balm was then evaluated through practical testing.

Prior to testing, I predicted that two formulations would melt at approximately 80°F, two at approximately 84°F, and two at approximately 90°F. The highest-temperature formulations appeared particularly promising, as they suggested a potential application as a solid lotion bar.

The results were less dramatic than anticipated.

All six formulations successfully achieved the primary objective. Each remained firm at room temperature while readily softening when applied to the skin. From Rose's perspective, this constituted a complete success.

From my perspective, the findings were considerably more complicated.

While all six formulations functioned adequately as hand balms, none possessed the durability required for more demanding applications. I would not confidently recommend any of them to an outdoor worker with severely chapped hands, nor would I trust them to survive prolonged storage in a purse or a hot vehicle. The discrepancy suggests that my predictive model, while directionally useful, does not fully capture the behavior of the finished product. Future testing will likely require formulations with substantially higher predicted melting points.

This introduces a new challenge.

Increasing durability generally requires increasing the proportion of structurally rigid ingredients such as beeswax. However, every increase in wax content necessarily reduces the proportion of beneficial oils that can be incorporated into the final product.

At what point does a balm become durable enough to survive summer heat while still retaining the properties that make it worth applying in the first place?

Rose's problem appears to have been solved. Unfortunately, the experiment has created several new ones.

Further testing will be required.
