Crackling ”Foam” Recipe
Hello. I recently was presented with a product in the form of ”crackling foam”. I can’t find the product online, because it has not officially launched yet, and may never will. I want to see if I can make a product like this, but the science of how it works, eludes me. I found similar products, of which only one I could find the ingredients list, and it’s this one:
BUTANE, AQUA (WATER), ALCOHOL DENAT., ISOBUTANE, PROPANE, GLYCERIN, BIS-PEG-18 METHYL ETHER DIMETHYL SILANE, MENTHYL LACTATE, HYDROXYETHYLCELLULOSE, PARFUM (FRAGRANCE), PPG-26-BUTETH-26, SACCHARIDE ISOMERATE, PEG-40 HYDROGENATED CASTOR OIL, CHAMOMILLA RECUTITA (MATRICARIA) FLOWER WATER, ALOE BARBADENSIS LEAF JUICE, POLYQUATERNIUM-4, PROPYLENE GLYCOL, CITRIC ACID, SODIUM CITRATE, ORYZA SATIVA (RICE) BRAN OIL, SCLEROTIUM GUM, ORYZA SATIVA (RICE) EXTRACT, PHENOXYETHANOL, ETHYLHEXYLGLYCERIN
I can’t for the life of me figure out what makes it ”crackle”.
Of the ingredients listed, I have never worked with PPG-26-BUTETH-26 and BIS-PEG-18 METHYL ETHER DIMETHYL SILANE, but from what I understand, none of them has any properties similar to that. And I don’t even know if this is indeed a similar product as I have not used it. It claims that upon contact with the skin, the bubbles crack, so I am thinking maybe in this formula the butane/isobutane mixture gets trapped in the foam and this is what produces the crackling.What I had my hands on, was a product that didn’t really foam (like shampoo), was more like a gel/silicone type, upon contact with the skin made just a small amount of crackling and bubbling, but when rubbed, produced an intense crackling effect. I don’t think it had some kind of microbeads inside that produced that crackling effect.
So I am buffled. Any help will be appreciated.
The main idea is to make a product in the form of a gelling foam, that heavily crackles upon rubbing.
If it turns out that a butane/isobutane/propellant mixture is to be used, I would also appreciate points on how to incorporate them in the recipe, as I have no idea how to work with them.
