Extending Soap Shelf Life with Preservatives

To make soap last longer and prevent microbial growth, it's essential to incorporate preservatives into your formulation. Preservatives help protect the product from contamination by bacteria, yeast, and mold, ensuring its safety and extending its shelf life.

Here are some of our recommended preservatives that can be used in soap formulations:

• PE 1090 Preservative: This is a broad-spectrum preservative that is paraben-free and formaldehyde-free. It is highly versatile, effective across a wide pH range of 3-12, and can withstand high temperatures, making it suitable for various cosmetic products, including soap.
• Mild Preserved Eco™ (Preservative-Free): While not classified as a preservative by the FDA, this gentle ingredient effectively inhibits microbial growth. It is suitable for cosmetic formulas with a pH range of 4-9 and helps retain moisture in the skin.
• Thyme Care™ (natural preservative): A natural preservative extracted from Thyme and Bois De Rose, effective in inhibiting bacterial growth. It works well in formulas with a pH range of 2-10. Please note it has a natural thyme scent.

When formulating, it's crucial to perform a challenge test to ensure the effectiveness and suitability of the chosen preservative for your specific soap formula before mass production and distribution.
