You have just received your therapeutic ointment: MyoRub+ Advanced, OrthoRub Pro Advanced, Physiogesic Pain Relief Cream, Physiomenthol or any other product from our range, and you notice that the texture is not uniform: one portion seems more liquid, another more dense, or the ingredients appear to have separated slightly. Don't worry: this is a natural phenomenon, well-known, and easily reversible.
What's really happening
Therapeutic ointments and creams are emulsions or mixtures composed of several types of ingredients: fatty bases (oils, waxes, emollients), active agents (menthol, camphor, essential oils like marjoram or lavender), and sometimes aqueous components. Not all these ingredients have the same temperature sensitivity.
In hot weather, whether during transport, in a delivery truck in summer, or during a prolonged stay in a mailbox or a vehicle parked in the sun, the most heat-sensitive components (often fats and waxes) can start to soften or even partially melt, more quickly than other ingredients. The result: a temporary separation, sometimes visible as oilier, softer, or more fluid areas on the surface or in the container.
This is a simple physico-chemical principle: heat reduces the viscosity of the fatty phases faster than that of other components, creating an apparent imbalance in texture.
What this does NOT mean
The solution: manual stirring is enough
The remedy is simple and quick:
The therapeutic and active properties of the product are not affected. The active ingredients remain present in unchanged quantities; only their distribution in the ointment may appear less uniform when the product has been exposed to excessive heat.
How to prevent the phenomenon
Some good practices to limit this type of inconvenience:
- Avoid leaving your products in a mailbox or a vehicle exposed to the sun for long periods in summer.
- Bring in your deliveries as soon as possible, especially on hot days.
- Store your ointments in a cool, dry place, away from direct light and heat sources.
In summary
An ointment that appears heterogeneous after delivery in hot weather is not a defective product; it is a natural and reversible reaction of the ingredients to temperature. A simple manual stirring is enough to restore its original texture, without any impact on its effectiveness or safety of use.
