Optiphen Preservative (1 Oz / 30 mL) Optiphen Natural Preservative for Cosmetics Water Soluble Paraben Free Broad Spectrum Preservative for Lotion Making

This was great to use for my DIY projects. I used it to make at home lotion this winter and even though the size was smaller than I wanted it was great for what I needed it for. 1 fl oz bottle. Directions were clear on how to use also.

Smaller than anticipated but a little goes a long way. I've been testing it in different products for both body & hair care, and it does do what it's supposed to.

The only thing about this item I thought it was a big bottle, but it’s a really tiny small bottle. The picture make it look like it is big, but it’s not.

Works great in lotion

This is a bit smaller than I thought it would be. I'll soon use it in my sugar scrub

Very good preservative for soaps, creams and serums

Have not used yet but looks es stayed

A+ use this when making homemade cosmetics
