Natrasorb Bath, Lisa asked: Can Natrasorb bath be used in face moisturizers for oily skin to absorb sebum? Is Natrasorb Bath the same as Tapioca Starch Polymethylsilsesquioxane?
The answer to the last question is no, it isn't the same as tapioca starch polymethylsilsequioxane. The INCI for Natrasorb Bath is Tapioca starch. It's been modified to hold a ton of oils in products like bath bombs or salts. I use it at up to 3% in my dry shampoo to hold fragrance oils and absorb sebum.
Can you use it in a facial moisturizer for oily skin? Sure, I guess. I've never tried it, but encourage you to give it a shot in a small batch and let us know what you think!
As a note, the INCI for Dry Flo TS is Tapioca Starch (and) Polymethylsilsesquioxane. That would be nice in a facial moisturizer. I have been making my dry shampoo with this ingredient to absorb sebum. (I'll be posting about this soon. There are just so many things to write about and so little time!)
In this same post, Carole asked: Is Natrasorb Bath a natural and safe product?
I'll answer the safe part this way: I use or have used every ingredient I mention on the blog on me and everyone I love. I would never suggest anything to you that I thought was unsafe. I do research on each and every ingredient on this blog to ensure we're using them at the suggested usage rate and within safe guidelines. I realize that I'm asking you to trust me on this one in a way, but I do include studies and links to other resources when I can so you can do your own work.
There really is no definition for natural, but I consider anything that had to be modified to get to be the way it is isn't really natural. So I consider something like olive oil natural, but I don't consider something like Honeyquat natural as it had to be modified to be positively charged. I don't consider Natrasorb Bath natural as it had to be modified to hold oils. But that's just my opinion. Others may have other definitions. This doesn't mean it isn't a good product, it's just that I don't personally think of it as natural.
How do I research my ingredients and make decisions about what to use?
Where do I get reputable information?
