Answer
Subject: Mold Growth in Homemade Cream
Hello! Regarding the mold growth in your homemade cream after two weeks, this is a common issue in cosmetic formulations and is usually due to microbial contamination.
The most frequent reasons for mold or bacterial growth in homemade cosmetics are:
- Insufficient or Ineffective Preservative: The cream either lacks a preservative entirely, or the type and amount used are not sufficient to protect the product from microbial growth over time. Different preservatives work against different types of microbes (bacteria, yeast, mold) and are effective within specific pH ranges.
- Contamination During Preparation: Microorganisms can be introduced during the making process from unsterilized equipment, containers, raw materials, or even from the air or your hands. Good manufacturing practices and hygiene are crucial.
- Water Content: Formulations containing water are particularly susceptible to microbial growth, as water is essential for most microorganisms to thrive.
As 'cosmeceutical7' mentioned, if the formulation is correct and proper hygiene is followed, storing the cream at room temperature should generally not be a problem.
To help pinpoint the exact cause in your case, it would be very helpful if you could provide more details about your formulation, including:
- The full list of ingredients and their percentages or ratios.
- The specific preservative you used and its usage rate.
- The steps you followed during the preparation process.
Providing these details will allow for a more accurate assessment of what might have gone wrong.
