Hello, Does anyone have any experience using ROE in LS? What were your observations? I've added it to a batch of perfectly clear soap at 0.1% of oils and it clouded the heck out of it. Would like input from people if anyone has done testing of their own. Thanks, Sapo

Does anyone titrate their soap using the total alkali test from Scientific Soapmaking to learn exactly how much acid to add in order to neutralize any potential free alkali? I've noticed that, when using citric acid, things aren't so simple. If using HCl, the test is straightforward and...

Hello, Could someone explain this to me: https://www.gracefruit.com/uploads/attachments/product/1173/ifra-butter-pancakes.pdf Under IFRA guidelines, this fragrance has 78.52% usage limit in category 4 (cologne, perfumes, body creams, lotions, ... generally "leave on" products). And yet...

Hello, Quick pointers as to why this baby cracked? 113g soda 57g citric 27g cornstarch shea butter+water+colorant+EO until moldable

Hello, Can someone point me towards books and other sources (from starter to advanced) where one might learn about bath bombs? Thx

Formulation: -coconut oil (SAP value 265 used) -olive oil (SAP value 196 used) -KOH (tested at 43.8% concentration) -distilled water 3:1 water:koh ratio This soap was formulated using the high end of the SAP value range, to be certain of complete saponification, with the realization that...

OK, so we all know how hygroscopic hydroxides are... my question is: Just how hygroscopic are they? At what point do they stop absorbing atmospheric moisture? More specifically, I make 50% solutions, will the concentration still drop over time, or is that sufficiently dillute? Thanks for...

Hello, what size batches do you people usually make, and what size batch was your maximum? Did you experience any mixing problems with size increases? I just made a 7lbs batch and the error is instantly obvious; the top of the paste tests neutral in both tongue test and total alkali test, and...

Is there a scientific way of evaluating soap efficacy? I.e. 100% olive soap versus 100% coconut soap in terms of how much oils each one can emulsify and subsequently wash off? The expected answer is that the coconut one is more efficient, but by how much? The answer, as I see it, could be...

If there are any would-be or fully fledged commercial soapers around here, I'd like to discuss equipment and production procedures. The following are my thoughts and findings, feel free to share your own or have a read! I will focus mainly on liquid soap, so there will be some similarities...

Interested primarily in liquid soaps, but also for bar soap. I imagine the answer is similar anyway.

On page 171 of Dunn's SSM: 1. Add water to 3 flasks, 50ml each. 2. Add phenolphtalein, 5-6 drops, to each flask. 3. Analytically add 10.XX KOH solution/suspect lye to each flask. 4. Add 5ppt or 500ppt (for either 5ppt or 500ppt lye) citric acid solution to the flask until the pink disappears...

Just thought I'd throw it out there, not really sure if it makes any difference or not, more of a technicallity I guess. But if Dunn is right, then we are wrong: When it comes to liquid soap, the reaction between potassium hydroxide and citric acid doesn't technically yield potassium citrate...

Notice: Don't pay too much attention to the butchering of chemistry terms and procedures I'm (probably) about to do and possibly already did with the title :mrgreen:. I'm more of an alchemist than a chemist :think:. OK, so, I've learned (so far only in theory, but soon to be tested on my...

Anyone have a recommendation for a good quality scale? Budget is always an issue, but reliability is key here (the soap will be for sale soon).

Can liberated FFAs be transparent? Or are they always white? I ask because I'm attempting to fix a failed batch (first overly superfatted, then overly KOH-ed, now attempting to neutralize with CA), and I don't have any parameters of determining when to stop adding CA, except for the visible cue...

If one was to...increase drastically the amount of water used when making paste, would the reaction between KOH and the oils still eventually take place? Paste probably wouldn't form... but still? Any guesses how long it might take? And what about if the paste is already made, and has been...

Quick question to see if my understanding of the subject is on point. If we have a 100% CO soap and a 100% EVOO soap, we tend to call the EVOO more moisturizing/conditioning, and the CO more harsh. But isn't this more a matter of...the EVOO simply being less stripping than the CO, in other...

Any idea how one would find out if the unsaponified matter of specific oils/waxes (e.g. jojoba or hemp oil) is of actual value (moisturization, conditioning, vitamins, texture, etc.) or provides no benefits? The unsaponifiable matter of this jojoba is listed at 46.4%...

I'm sorta trying to cash in on past experiences here, those things are expensive :mrgreen:. I'm wondering which EOs you guys have tried and what kind of results you got? Cloudyness, random thickness/thinness, complete dissipation of scent, rancidity, floating on top instead of emulsifying...
