Question
What is the heat tolerance of ActiveRelease Retinal™? I need to dissolve Capryloyl Salicylic Acid (LHA) in oil first, which will involve heating the oil. How much should the oil cool down before adding ActiveRelease Retinal™?
Answer
Heat Tolerance for ActiveRelease Retinal™ and LHA
Based on the product information:
- Capryloyl Salicylic Acid (LHA): This ingredient needs to be mixed into the oil phase by heating to 70-80°C to help it melt and dissolve. It can withstand heat up to 80°C.
- Retinal-EZ™ (ActiveRelease Retinal™): This product is sensitive to heat and should be added in the last step of your formulation process, without being exposed to heat. The product description recommends storing it in the refrigerator (2-8°C) and avoiding heat and light.
Therefore, after dissolving the LHA in oil at 70-80°C, you must allow the oil mixture to cool down significantly before adding the ActiveRelease Retinal™. To ensure the stability of the Retinal, it is best to add it when the temperature has dropped to room temperature (around 25°C) or lower.
