Cleansing Water Sedimentation and Turbidity Issues

Question

Hello, I'm experiencing a problem with a cleansing water formulation I mixed. After leaving it for about a month, sedimentation occurred, and when shaken, the water turned cloudy. I'm unsure what might be causing this. I have attached the formula file. Thank you in advance.

Answer

Hello,

I understand the issue you're experiencing. It's common for cleansing water products to develop sediment and turn cloudy when stored for a long time.

Since I cannot access the formula file you attached, it's difficult to pinpoint the exact cause. However, here are some common reasons that might lead to sedimentation and cloudiness in cleansing water formulations:

  • Microbial Contamination: This is one of the most frequent causes. Sedimentation, cloudiness, or changes in odor often result from the growth of bacteria, mold, or yeast. This can happen due to contamination during manufacturing or if the preservative system used is insufficient or doesn't cover a broad spectrum of microbes.
  • Ingredient Incompatibility: Some ingredients in the formula might react with each other over time, leading to separation, precipitation, or cloudiness.
  • Insufficient or Ineffective Preservation: If the preservative concentration is too low or the chosen preservative is not suitable for the formula and its pH, it may not effectively inhibit microbial growth.
  • Improper Storage Conditions: Storing the product in areas with high or low temperatures, or frequent temperature fluctuations, can affect the formula's stability.
  • Use of Non-Cosmetic Grade Ingredients or Water: Impure water or ingredients containing contaminants can lead to instability or sedimentation.
  • Ingredient Degradation or Oxidation: Some ingredients may degrade or oxidize when exposed to air or light, causing physical changes like color, odor, or cloudiness.
  • Precipitation of Ingredients: If certain ingredients have limited solubility in the formula, they might crystallize or precipitate out over time.
  • pH Changes: Changes in the product's pH can affect the solubility of some ingredients or the efficacy of the preservative.

Initial Recommendations:

  1. Review the Formula: Consider if any ingredients might be incompatible or have a history of causing issues in other formulas.
  2. Check the Preservative System: Verify the type, concentration, and effective pH range of the preservative to ensure it's suitable for your formula.
  3. Manufacturing Process: Ensure that the manufacturing process is clean and hygienic, including the containers used.
  4. Ingredient Quality: Confirm that cosmetic-grade ingredients and purified water were used in the production.

If possible, conducting microbiological testing on the product can help confirm if the issue is due to microbial contamination.

I hope this information is helpful. Providing more details about the formula might allow for a more precise analysis of the cause.
