Actually I see their site is back up again - however in a completely different form, and makes no unwarranted claims now. Fair enough.

For those interested, the Advertising Standards Authority has upheld my complaint against Lavylites:
“For products that would be classed as medicinal, either by function or presentation, marketers must hold a Marketing Authorisation (MA) from the Medicines and Healthcare products Regulatory Agency (MHRA) before advertising that product in the UK. However, it seemed that the advertiser had no such licence and making such medicinal claims for an unauthorised product are contrary to Code rule 12.11 and constitutes a clear breach of the Code.”
However, the Web site is down “for maintenance” and as a result the ASA isn’t taking any action unless they put it back up again. -
Aha one of my competitors I see. Cold Process Soap and those climate conditions are opposites. Especially, high humidity causes the soap to sweat. We keep ours under refrigeration.

If it gells it will likely be a tan colour and not as desired.

I recently was advised to add half the milk for making the lye solution, then mix the rest of the milk directly to the oils.
Sounds like a bad idea. The high concentration of the NaOH will probably oxidise the milk. And the rest of the milk won’t mix with the oils without blending any more than the water will.
Others prefer to add the rest after trace so that half of milk’s fat won’t react with the NaOH.
Also doesn’t sound great. The reaction is only just beginning; it’s nonsense to assume “half won’t react”.
Goats milk soap is nice to use but making it is not easy. I suggest you freeze the milk into cubes then use a kitchen blender to turn it rapidly into slush. Mix this with the NaOH and keep the mixing vessel in a water bath to absorb excess heat. Take care to keep the batter cool, try not to let it go through gell. Of course the cure period will be longer as a result. -
Ah yes. I made a daily moisturiser / sunscreen product last week at the seminar. It has ZnO of some pre dispersed form, two other UV absorbers, and a lot of advanced silicones.

Well what is the alumina for, do you think?
-
I’ll ask my Kao supplier for that. Thanks.
-
Wow that is interesting. I will check which version I am using. Thanks.

I generally use a 1KW hotplate with temperature control, and a 4Kg stainless steel bowl, with frequent stirring, if I am melting things like glyceryl stearate and cetyl alcohol and shea butter and so on.

Well, I really had in mind Pyrex beakers. If you heat in the microwave you can only heat water based or mixed phases, not lipids alone.
-
I’d guess that it might be the phenoxyethanol, because it seems much less likely that the hexylene glycol would be the issue; HG is noted as being less irritating than PG. Highly unlikely to be the sorbate or CG. If I were you I would test this directly by diluting the preservative to 0.5% and doing a patch test. I assume you have no essential oils in there.
-
Cold process soap needs no preservative. Its shelf life is dependent on the oils used; if you use stable oils then there should be no problem.
Are you certain the preservative and not another ingredient is the cause of your issue? -
Pyrex.
-
I think you need to define your terms of reference. Carbopol “organic” eh… ?
-
Triclosan is an ingredient of serious environmental concern, I urge you not to use it.
-
It sounds as if you have got bentonite clay in there, in which case I would expect pH drift to the alkaline side.
-
@chemist77 It’s called the “back acid” technique, a peculiarity with Aqua SF1. If that’s what he’s using.
-
So what advice did you find to recommend sodium salycilate as an anti acne additive? Why would you believe it has the same effect as salycilic acid?
-
Yes, Ashish. It’s not a linear relationship, I noticed that I have to carefully adjust each batch by hand, a little too much takes it to something more like plastic flow.
-
Yes, there is a known risk of that happening. I have read up on this in depth. I have obtained a good quantity of wigs and tresses of natural hair. The user should be advised in large print to test on a small section of hair, first.
My initial tests show that I need to recalculate the strength.
Thanks for your comment! -
Funnily enough I just came back from a seminar given by Univar and Corbion Purac was represented. They make a very pure version of lactic acid with hardly any odour. Besides lactic acid and sodium lactate they also have potassium lactate, calcium lactate, zinc lactate, sodium lactate + sodium gluconate, and ammonium lactate. And I have no idea what all those might be used for.
-
Yes, the above ^^^.

Maybe the good bacteria are supposed to eat bad bacteria. (Laughing)

Take it out of the water.
