Cream Formulation Issues: Strong Smell from LipidSoft F and Silver Nano Preservation

Based on the information provided by the staff, the strong, rancid-like smell you are noticing in your cream is likely the natural characteristic scent of LipidSoft F (Ethyl Linoleate). This does not necessarily indicate that the ingredient is spoiled. The staff suggested two methods to mitigate this smell: 1. Adding fragrance to mask the scent. 2. Using a scent masking agent like Citromask. Regarding preservation, the staff confirmed that silver nano can function as a preservative if it is fully dispersed in the formula. Please ensure thorough mixing for it to be effective.
