Issue with Rotten Smell and Gas in Formulation

Regarding the rotten smell and gas buildup in your formulation, the staff's explanation is correct. This issue is likely caused by the interaction and fermentation of Aveenoat™ (ID 1398), Hydro Protein (ID 231), and Lemon Peel Bioferment (ID 218).

These ingredients, particularly plant-derived proteins and ferments, can be prone to microbial growth and fermentation, especially when combined.

You mentioned using nano silver Pure™ (ID 857) at 1% as a preservative. While nano silver does possess antimicrobial properties, it might not be sufficiently broad-spectrum or potent enough on its own to prevent the fermentation caused by this specific combination of ingredients, which essentially provide a food source for microbes.

The smell and gas are clear indicators of microbial spoilage, and unfortunately, the product is likely not usable.

To avoid this issue in the future, we recommend following the staff's advice: choose only one ingredient from the group of Aveenoat, Hydro Protein, or Lemon Peel Bioferment for your formulation. Additionally, consider incorporating a broad-spectrum preservative system suitable for your formulation type, even when using ingredients with some antimicrobial properties, to ensure stability and prevent microbial contamination.
