HP soap and CAPB
Has anyone else tried “improving” HP soap with synthetics? I just tried adding 5% CAPB to a batch of HP soap (mixing in at the end of the process to avoid excessive foaming during the cook.) It seems to have come out just fine so far. My aims being, to reduce irritancy and increase foam. I wonder what % would be optimum?

I did
it makes them nicerbut soap biggest problem remains: its high pH
Hot process has lower (less high) pH than cold processbut the big problem is soap chemistry
so you can’t lower it’s pH much without having it revert back to free fatty acid.IMO the best solution is skip saponification altogether
and start with fatty acids (either buying premade distilled fatty acids, or hydrolyzing oils with an acid catalyst yourself)Then neutralizing the fatty acids with Ammonium carbonate (or bicarbonate)
to get an Ammonium soap that seems to handle lower pH without decomposing.Somehow ammonium carbonate works so much better (and not as smelly) as neutralizing fatty acids with ammonia.

I cannot imagine where I’d be able to obtain ammonium carbonate unfortunately.

In a general purpose chemicals shop that sells some food grade chemicals,
as Ammonium carbonate/bicarbonate are often used in bakery. -
Saludos @Belassi ,
I tried ussing SLES, SLS, CAPB and combinations yo bost foam, and the only one cost/effective was SLES (70%) at 4% - 5%, i was making soap ussing mostly Tallow that makes almost no foam, and sles gives a good lather, besides that the foam doesnt compare with ussing coconut or palm kernel oil (wich is im ussing right now) in ratios arround 70:30-80:20.@Gunther Ammonium and sodium carbonate in my country are restricted materials and are selled under supervition of the authorities, due to it use in making Cocaine and by-products. Maybe thats could be the reason for the impossibility of belasi to find it.

That’s interesting because Ammonium carbonate/bicarbonate don’t seem to be in the chemical precursors list
at least not in Category I or II listed below

While I read that junkies use Sodium bicarbonate to make crack from cocaine
Sodium bicarbonate ain’t a controlled chemical AFAIK. -
@Gunther Cocaine base, or “crack” cocaine, is the base form of salt, which is usually made using sodium/ammonium bicarbonate and can be smoked
-
@luiscuevasii the paper mentions Sodium, not ammonium bicarbonate.
AFAIK baking soda ain’t a restricted chemical. -
@Gunther “Cocaine (powder) is dissolved in a solution of ammonia or sodium bicarbonate (baking soda) and water”, theres a lot of information for ammonium and sodium carbonates uses to make “crack”. Althought baking aoida is a lot easier to find.
In fact in my country Venezuela, neightbor of the biggest cocaine produccer (colombia), all of the Urea, and ammonium salts and compounds are highly restricted and sold only by high supervision of the govement. Thats could apply to Mexico too, wheres Belassi lives.
