Hola,

Analizando microbiológicamente una fórmula anhidra con 96% de manteca de karité y 4% de partículas exfoliantes de piedra de almendra, se obtiene un resultado estimado de 70 UFC / g (este es el recuento de cultivos de bacterias aerobias mesófilas UFC / g de bacterias ( UNE EN ISO 21149.2017). Se realiza un segundo análisis y se obtienen 140 UFC / g (el valor del conteo está dentro del límite establecido por el laboratorio (1000 UFC), ¿sería aconsejable realizar un tercer análisis o podría considerarse liberar el lote?

Gracias por sus respuestas.

Hello,

Microbiologically analyzing an anhydrous formula with 96% shea butter and 4% exfoliating almond stone particles, an estimated result of 70 CFU / g is obtained (this is the count of cultures of aerobic mesophilic CFU / g bacteria ( UNE EN ISO 21149.2017) A second analysis is performed and 140 CFU / g are obtained (the count value is within the limit established by the laboratory (1000 CFU), would it be advisable to carry out a third analysis or could it be considered to release the batch?

Thank you for your answers.

Puede permitir si quiere, pero en futuro incluya un preservativo aun la es anhidra. La probaria de nuevo porque usted resultados estan aumentando (lo parece).

e.j Symdiol 68 (1,2 Hexandiol y Caprylyl Glycol)

You can allow if you want, but in the future include a condom even if it is anhydrous. I would try it again because you results are increasing (it seems).

@EVchem preservative in spanish is “conservador”, preservativo is a condom.

@Econatural realizaron pruebas de estabilidad y de desafío en este producto? Y cuanto tiempo hubo entre los dos conteos microbiológicos? // Did you do stability and challenge testing on this product? How long passed between both microbial enumeration tests were performed?

Thanks for the @evchem answer and the advice to include preservative in future batches. I think it is a good idea to repeat the analytics one more time to see the evolution.

Thanks for the reply @letsalcido. The time that has passed between the two results obtained is 15 days.

Can it be expected that even being an anhydrous product, it will develop microbial contamination to exceed the established limit of 1000 CFUs?

Would it be acceptable to use Sharomix as a preservative in future batches?

@EVchem, It would be Sharomix 705 (Benzoic Acid, Sorbic Acid, Dehydroacetic Acid, Benzyl alcohol)
