Hello, Note: food grade pure mag. hydroxide is used, I ate/zap tested some, no sensation, zap or taste at all. I am attaching pictures of magnesium hydroxide+babassu deodorant in an aluminum container. It appears to react with and dissolve the aluminum over time (2-3 days after 'bottling')...

Hello. Any insights or experiences on the differences between Magnesium hydroxide, oxide, chloride, citrate, sulfate for deodorant purposes? Are they interchangable? Thanks

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

You're wrong. None of the Bronner's soaps contain a preservative. You picked the only product they have that does not use EOs for scent (therefore the only possible one that could have hidden Naticide) and claimed that Natural Almond Fragrance=Naticide, when it is likelier* (natural)...

Does the buffering effect mean that more citric acid is required to neutralize the free KOH in ACTUALLITY (rephrased question: does the buffer material/solution "eat" some of the acid? Thus requiring more overall?) or does that simply mean that the test and indicator itself are less reliable due...

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...

I know this is an old thread; but I am curious as to where you (IrishLass) found EU usage rate recommendations for specific essential oils in Essential Oil Safety? The EU gives no such guidelines, merely mandates that usage rates over 0,01 % (soap) be declared on the label. Nor can I find any...

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

Just to be clear: I was adding citric acid, not KOH, to the first (high end of SAP value used) formula, thinking it might have something to do with excess KOH. The floaty layer is present in both 100% potassium olivate as well as in the 100% potassium cocoate in pretty much the exact same form...

In contrast, here is a soap formulated with reverse logic in mind, using the LOW end of the SAP value for each oil (thus assuring that there is zero possibility of a lye excess). All ingredients/batches identical. You can clearly see unsaponified FFA/oils being suspended within the soap at the...

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...

Good idea with the weighing. Certainly a more elegant indicator than measuring the concentration over and over, which is what I would've done :headbanging:. On it. Thanks all!

True, forgot about CO2 - This would effectively neutralize the lye over time, regardless of moisture presence. Very tighly sealed container - this is the part that boggles me.

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...

Attempting to join, sounds good and informative. So far not accepted.

Thanks for that info. One would expect they'd use some high powered high RPM mixers to "substitute" for the increasted liquidity (slowed saponification). But the mixer seems quite slow. Also; I wonder if the contents are heated.

Thanks Deanna and Zany for the comment on cold process/only initial heating LS with using just water. One more question - after how much time do you experience full saponification when using only water and no heat? And ditto on the "do test batches of various essential oils". Some tests may...

To the CPLS makers: do any of you use water, or are you all glycerin users?
