Optiphen | Cosmetic Grade | DIY Skincare & Beauty Formulations | 4.05FlOz / 120ml

Does the job, no complaints, currently using in home made sugar body scrubs.

I’ve tried skipping preservatives in my homemade stuff before and let’s just say... I learned real quick that water + time = weird smells and slime. So now I don’t mess around. I use this in anything I make that involves water, like my whipped lotions and little soap experiments, and it’s been doing what it’s supposed to do without giving me a hard time. I usually measure it out with a syringe since I’m always trying to eyeball things and this makes it a lot less chaotic. So far, everything’s stayed fresh and nothing’s gone funky on me. It plays nice in my recipes, and I don’t notice any weird smells or textures. It came in a good-sized bottle too, which matters when I’m making stuff in batches. I use around 1% depending on what I’m mixing up and it stretches pretty far. Definitely makes the whole process feel more reliable.

Does a good job for what I use it for which is rice water hair strengthener that I do homemade you don’t need much either so the bottle goes along way

this is what was recommended for making Conditioner Bars,

This is my absolute favorite preservative to use for my liquid soaps and lotions! It’s easy to use and effective with keeping my products well preserved. My lotions and soaps leave my hands and body feeling well moisturized . This is an excellent product, well worth the money!
