Solid Cleanser formulation
Hello,
Below is the Ingredient list to PCA’s Dry Skin Relief Bar (in a jar).
Ingredients:
Water, Saponins, Vegetable Oil, Glycerin, Aloe leaf juice, Pumpkin Seed Extract, Pumpkin Seed Oil, Fennel Oil, Honey, Lavender Oil, Lecithin, Resourcinol, Salicylic Acid, Soybean Oil, Tocopherol.Aspect: very hard, clear, dark brown in color
Pkg: Plastic jar, a sponge is provided for lathering and application.Question:
Is this a classic glycerine soap recipe and this INCI is not complete (ie. NaOH not listed?) Or is this a very clever natural formulation? What are the ingredients that are making this bar hard?I have been trying to make a natural cleansing bar at a low pH (5) (ie. not soap) and having a very hard time finding any innovations around this.
Any thoughts, greatly appreciated!
Thanks,
AC -

Thanks @johnb for the comment. I got the INCI directly from the PCA bar packaging. Very strange, but it may explain why it looked incomplete. The pH of this bar is 6, which is hard to achieve with a typical soap formulation. Some confusing information.

The INCI listing that I gave is incorrect - although it is the same one repeated several times by different retailers.
I only cursorily looked over the list before making my post. I now see it is incorrect/incomplete - so much so that I am stumped as to what it could really be. There are some things there that are just plain wrong. For example, salicylic acid in the same product as sodium hydroxide - one will neutralise the other and render their inclusion pointless.

Good point. I’m guessing one may be from old packaging and the other from new. But regardless, it appears they are not listing this formula correctly. The mystery continues…

The saponins are a newer direction that some “natural” cleansing products are using. Years ago I used a source of these from Soap Berry Extract. My experience was that they cleansed but were difficult to get good lather or rinseability. There is some thought that they even have some preservative properties. They are not saponified, hence the lack of a strong alkali. Coincidentally here in the US the combination of Salicylic acid and Resorcinol would make it OTC. If I recall correctly the Resorcinol is only allowed in combination with Sulfur so it is even an unapproved OTC.
