General Information: Glyceryl Caprylate has an excellent efficacy against bacteria and yeast and as such makes a great preservative for skin care. It works at pH between 4.5-7 and is approved for use in the EU, US and Japan. The ingredient can be added to the water phase of an emulsion where it will melt at temperatures over 30C. It can be heated up to 80C without problem and is also compatible with surfactant solutios and alcohol based products. The excellent wetting ability of this ingredient can mean that emulsions are thinned somewhat so trials are recommended so that any adjustments can be made.
Formulation Note: The glyceryl caprylate works really well with our p Anisic Acid to give broad spectrum protection.
Caution: In some formulation types, especially leave-on balms or face masks that are occlusive in nature, this ingredient at the higher level can be quite irritating to the skin and leave it flushed red. In those formulations it is wise to stick to 0.5% or less and to check whether, at this level, the ingredient is still providing adequate preservation.
General Note: The only way to be sure that your preservative system is working in your product is to carry out micro testing. While we are happy to pass on information and make theoretical recommendations of how to get the best out of our ingredients we can make no guarantees without this testing. There are two levels of test that a microbiological lab will do - one is a micro count which gives you a 'moment in time' look at the cleanliness of your formula and may also characterise the microbes present. The second is a Preservative Efficacy Test or PET. This is highly recommended as it tests how your product performs over time when it is challenged by microbes. You are legally required to market and sell products that are safe and microbial stability is an important part of that.
Please note: This product may come with less than a 9 month shelf life. If used within the specified shelf life, it will not affect the preservative efficacy in a product.
