Versatile preservative BL is a water soluble natural (Ecocert, Cosmos and Natrue certified) and palm oil free preservative. It is very effective against Gram+ and Gram - bacteria and moderately effective against yeast and mould. In water based products such as tonics, micellar water, cleansing foams and gels it is effective as a stand-alone preservative but in emulsions it needs a preservative booster or co-preservative which is effective against yeast and mould .
We've added Versatile preservative BL to our product portfolio because it tolerated lower pH better than preservative 1388 eco. Please be aware that because of the sodium benzoate in this preservative blend, you would not be able to claim your product as "preservative-free" . Apart from that, benzoic acid and sodium benzoate concentration is subjected to limitations in the EU and in most parts of the word. If your other ingredients are preserved with sodium benzoate, the total (sum) concentration of all sodium benzoate or benzoic acid should be calculated in order to comply with the regional legislations.
Versatile preservative BL increases the pH. Make sure your product has a pH of minimum 5 as you add Versatile preservative BL. Measure the pH again and adjust it between 4,5-5,5 by using lactic acid or citric acid.
Application dosage: 1,5-2,5%
max. allowed dosage in the EU: 5,0%
