Myoc Optiphen – 2oz (60ml) | Cosmetic Grade Preservative for DIY Skincare, Haircare, Creams & Lotions

This is a good preservative as it helps to slightly lower pH, can be used in hot concoctions also.

Making organic care products, I needed to use a preservative. This was the best I could find. Happy with it

This was one of the safest preservatives I could find for my caffeine hair serum. It mixed well into my formulation without altering texture or consistency, and being paraben free is great as I am trying to keep it healthy. It does work, as my serum hasn't gone off, I still keep it in the fridge, but it definitely lasts longer. It does only work within specific pH ranges, so checking this is important. The 60ml bottle lasts a while since only a small amount is needed per batch. It’s a good option if you want a reliable preservative for DIY projects, but proper formulation knowledge is key to using it correctly.

I have used Optiphen before and find it works well to keep my DIY formulations useable beying a few days. It’s nice to not have to keep things in the fridge and use up after a few days due to the water phase. I’m using it for homemade shampoo and face and body moisturisers and given the tiny percentage needed to be effective, this small bottle should last for AGES.

Yes, even when diluted in handwash and tap water, Myoc Optiphen still poses an environmental risk because its key ingredient, phenoxyethanol, is harmful to aquatic life and does not completely break down in wastewater treatment.

As preservatives go Optiphen is definitely a good choice but I have to be honest and say I didn't recall it being as expensive as it was for such a small bottle. It's a plus that its free from Parabens and formaldehyde and it's alos useful thats it oil soluble. A great choice for hobbyists or crafters making their own recipes.

Too small

It did the work
