Optiphen Plus - Optiphen + Water Soluble and Gentle Preservative 2 Oz - Our Formula of Optiphen with Sorbic Acid - Enough Preservative for About 12 Pound of Solution

This works well in my DIY household products. I have used it before and it just what I need. It arrives quickly and in good shape.

Major ingredient in my hair care.

Honestly i just read what it’s for and bought it. I’m in my DIY era. Works fine

I’ve ordered this product multiple times. Works great. I use this to make homemade body wash. It has helped to keep the nasties and germs away. I’ve tried other products but this one seems to work best for my body Wash.

This is good as preservative for my homemade beauty products to extend life. Only complaint is its small.

Now that I add a bit of this to my homemade hair gel, it keeps much better. It lasts a few weeks without getting that rancid smell. Would probably last longer, but I use it up in that amount of time.

Used for my cosmetics business & love it. I would recommend to others

Hard to gage amount in small batches especially when you aren’t mathematically inclined
