Storage Conditions for Silane-Coated Powders and Liquid Phytic Acid

Asked by: jwaroonsiri On: December 03, 2025 Product Type: Cosmetics

Question

I would like to inquire about the storage conditions for two types of cosmetic ingredients:

  1. Silane-Coated Powders (e.g., Triethoxycaprylylsilane coated powders such as Mica Powder, Sericite Powder, or Talc Powder).
  2. Phytic Acid (50% Liquid, Natural).

Should these ingredients be stored in the refrigerator, or can they be stored at room temperature?

Answer

Based on the general stability of these ingredients and the specific product information available:

1. Silane-Coated Powders (e.g., Triethoxycaprylylsilane Coated Mica, Sericite, or Talc)

Silane-coated powders, such as Mica Powder (20 Micron, Silane Coated), are generally very stable dry powders.

  • Storage Temperature: They can be stored at room temperature.
  • Conditions: Store in a cool, dry place, tightly sealed, and protected from moisture and direct sunlight.
  • Refrigeration: Refrigeration is not typically required and may not be beneficial, as the primary concern for powders is moisture absorption, which can be exacerbated by temperature fluctuations when removing the product from the fridge.

2. Phytic Acid (50% Liquid, Natural)

For liquid Phytic Acid, such as Phytic Acid (50% Liquid, Natural), specific storage recommendations are provided to maintain its quality and shelf life.

  • Storage Temperature: It is recommended to store in the refrigerator (a cool place).
  • Conditions: Store in a tightly closed container, protected from sunlight, air, or heat.
  • Reason: This product is a 50% solution in water and does not contain preservatives, making it more susceptible to degradation or microbial growth over time if stored at higher temperatures. Proper storage ensures the minimum shelf life of 2 years.
