I used this ingredient in a facial serum and noticed a significant improvement in shelf life. The product stayed fresh for over two months without any signs of spoilage. It works well with other natural ingredients.

Good preservative for water-based lotions. I mixed it with aloe and vitamin E and the blend stayed stable even after a month in a humid environment.

Used in a daily cleanser formulation. The texture remained smooth and the product didn’t develop mold or odor after several weeks of storage.

Works as expected, but I found it slightly less effective in very low pH environments. May need to adjust formulation for optimal results.
