Preservatives for Homemade Powder Cosmetics

Yes, it is necessary to use a preservative in homemade cosmetic powder products. Even in powder form, products can come into contact with moisture from the environment or during use, creating an environment where microorganisms can grow. Preservatives help prevent the growth of bacteria, fungi, and yeast, ensuring the product remains safe and stable.

For powder products, a preservative that is also in powder form is generally recommended for ease of mixing.

A suitable option is NaturePreserve™ Ultra (Gluconolactone & Sodium Benzoate).

• It is a natural, broad-spectrum preservative.
• It is effective against bacteria, fungi, and yeast.
• It is a white powder, making it suitable for powder or dry formulations.
• It works in a pH range of 3-6.
• The recommended usage rate is 0.75-2.0%.

Another related preservative is NaturePreserve™ LB2, but this is a liquid form and may be less convenient for purely powder applications compared to the powder form of NaturePreserve™ Ultra.
