This is a broad-spectrum preservative blend suitable for natural cosmetics and allowed under some organic certifications as a permitted input. The preservative comes in powder form and is easily dispersed into your water phase at any point during manfuacture. It is permitted for rinse off and leave on applications and with a pH range from 3-6.
In some formulations this preservative may cause a slight downward drift in pH. This is caused by the gluconolactone slowly releasing gluconic acid over time. If this pH shift is found to be an issue the pH can be buffered with our Sodium Citrate powder. We have a guide to buffering your product using sodium citrate available here.
This preservative has been found to have little effect on emulsion viscosity and is clear and has very little aroma. However, it is important to note that the ingredients water solubility changes with pH. As the pH gets lower, water solubility decreases and the preservative may precipitate out of solution. Ideal pH is 5-6.5. Formulations containing sulfates and/or glycerin may find this less of an issue as these boost preservative solubility.
Material Chemistry: Nature-identical.
Recommended Use Level: 2%
pH range: 3-6.5
Heat Tolerant: Yes but only tolerates high heat (70C plus) for a short time.
Material Incompatibilities: Nothing to report.
Microbial Action: Broad Spectrum - bacteria, yeast, mould.
We always recommend carrying out micro testing on your formulations prior to launch as micro stability is a requirement for all cosmetic products. The simplest micro testing consists of a micro count which is carried out by a micro testing laboratory who can confirm the number and type of microbes present in your formula. A cosmetic product does not need to be sterile so some microbes are acceptable but no pathogens should be present and total viable micro count should be below 1000 CFU/g for a regular cosmetic (less for babies and eye products). Preservative Efficacy Testing is recommended for commercial products that contain a water phase, especially where the packaging offers little protection against contamination. This test challenges the preservative to see how it will stand up to repeat use. There is more information about this and other micro tests on our website here: Preservative Testing.
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.
