Optiphen Plus Preservative (60 ml / 2 fl oz) - Cosmetic Grade Broad-Spectrum Protection for Serums Lotions Creams Shampoos & DIY Formulations

This is a really good preservative it helped keep my skincare products good and helped it spoiling for a long time. It's been a few months and the product still seems to be doing well so I would definitely recommend this was really easy to use. Just don't exceed one percent usage.

I ordered this Optiphen plus because I make my own handmade lotion. I typically pay $6.99 per ounce from a trusted source outside of Amazon that I’ve ordered through for years. This 2 ounce bottle on sale for eight dollars and some change is a great deal. The price point is fair even at full price at $10.99. The look of the product falls in line with the look of products I’ve ordered from trusted vendors. I haven’t actually used this product yet, but the only true test is to add it to my lotion and see if the lotion holds up for an entire year. I didn’t wanna wait that long to make this review but should it not work out I will update my review.

I’ve been using Optiphen Plus Preservative in my DIY skincare and haircare projects, and I’m loving it! It’s been super helpful for making my own lotions, sugar scrubs, and even serums. I usually stick to small batches since I tend to use them up quickly, but I love that this preservative keeps everything fresh. It’s so easy to use—just 0.5% of the recipe, and it blends right in. It gives me peace of mind knowing my homemade products are safer and will last without the need for parabens.I’ve never had an issue with the products going bad. It’s a great option if you’re looking for a natural preservative that’s both effective and simple to use. Definitely recommend if you’re into DIY skincare!

Hard to review this product. It came on time and it came intact. sealed well and not leaking. Glad to have it!

This product is super useful if you like to mix up your own lotions, creams, serums, etc. To my understanding it is only to be used in topically applied products, so I am not using it in things like saline nasal spray or vitamin C serum used for microneedling. I would love it if the company would provide more information on when to use this product vs. the Germall product as I am unclear on which one should be used when, but I'm happy with this product!

This is an excellent preservative to use in do it yourself skincare and haircare formulas. It's a great alternative to using parabens as preservatives. Optiphen Plus contains phenoxyethanol, caprylyl glycol, and sorbic acid. I use it to preserve my formulations which have a pH below 6.0 at a concentration of 0.5%. My formulas which have used Optiphen Plus have continued to smell fresh until I have used them up.

Good preservative for my handmade skin care products.

I love optiphen plus for my lotions and liquid soap! It’s an amazing preservative and it lasts a long time! Excellent product!
