## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product!
*by P***R on March 12, 2026*

Excellent product! I use this product in my sugar scrubs, soaps, fruit, vegetable and botanical infusions. Highly recommend to other buyers. Thank you so very much! ❤️

### ⭐⭐⭐⭐⭐ Works well
*by A***K on January 24, 2026*

All natural preservative. Works as described. Good value

### ⭐⭐⭐⭐⭐ Reliable broad-spectrum protection for DIY skincare
*by S***S on December 29, 2025*

I’ve been using Optiphen Plus for my latest batches of water-based lotions, and it provides great peace of mind. I love that it’s paraben-free and formaldehyde-free while still offering broad-spectrum protection against bacteria, yeast, and mold. It incorporated easily into my emulsions during the cool-down phase without thinning out the texture. It’s a must-have for anyone looking for a more "natural-friendly" preservative that actually works. Highly recommend for home formulators!
