Leucidal Liquid SF Max Natural Preservative Alt for Skin Care Making 16 oz | Skin Perfection, Made in USA, Vegan, Water-Soluble; for Cosmetics Lotion Soap Making Hyaluronic Acid Vitamin C Serums Creams

The only preservative I use in my skin products. Highly effective. I've bought from them 3 times so far. No problems. My products last over 18 months on the shelf. Definitely worth the price.

Good stuff

The liquid is clear and easy to measure with a dropper or syringe. It mixes smoothly into water-based recipes without changing texture or color noticeably. The 4oz bottle is a practical size for small-batch makers and comes with clear usage guidelines on the label. The product has a very mild, almost neutral scent that doesn’t overpower homemade formulations. This appears to be a straightforward natural preservative option for water-based DIY products. I’ll update after 6–8 weeks of continued testing in various recipes to report on long-term stability, consistency, and overall performance in different formulations. These seem like a useful preservative for homemade skincare enthusiasts looking for a Lactobacillus-based option in a convenient size. I’d recommend it for small-batch lotion and cosmetic makers who want a natural alternative.

Love it

I am an all natural and organic product formulator. I really like the ability of the preservative to keep my products safe from mold, bacteria and fungus. I utilize several other preservatives, this is one of my favs. I didn’t realize that the container was as small as it is for the price, but product works as described.

Smell was great and product was delivered on time.

I'm really disappointed the manufacturer doesn't include a customer service number to call and ask on measurements and percentage of liquid needed to protect (at least 4oz ?) lotion.

I like this preservative for my NON AQUEOUS products I would never use this preservative in lotion or any other water containing product because that's not what leucidal liquid is for at least not to be used alone. People using this in products that contain mostly water need to do more research before writing a bad review and further more selling a product to customers that don't have the correct preservative used in it. It is not this sellers responsibility to tell people what products to use this preservative in. I gave 4 stars because it's very expensive for the size.
