The images describing the product on Amazon don't entirely correspond to the product you receive. In the photo, the bottle looks white, but what you receive is a clear bottle with a yellowish liquid inside. In the photo, you can see a dropper for measuring. There is no dropper. The product is a simple, clear plastic bottle, without a box. I'm not suggesting that the product will be of inferior quality. I'll leave that up in the air until I've tested it on cosmetics. It will take time. However, the product is fresh, almost recently made. That is excellent. There is also a date when the product was made and when it will be its expiring date.

I make various preparations as I need them, so this paraben free preservative is just what I needed to keep my items fresh. It mixes well with essential oils and gives my lotions and creams that extra bit of protection. The price is quite reasonable.

My daughter is trying out tinkering with cosmetic products like soap, conditioner, and lotions for herself, so I got this to encourage her hobby. She doesn’t have too much experience, but from what she’s said so far, it seems to be working perfectly well for her needs. Highly recommend!

This was an important ingredient to products I was making. I am very pleased with my purchase and would recommend it.

Arrived quickly and does what it says, be careful when using this so where gloves and protective gear because it is a bit funny on your skin and doesn't wash off very well and yeah chemicals.

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,
