That’s exactly what I wrote, I don’t like to buy color cosmetics online (unless I know the number I need).
That’s why I wished her brand would be available in the shops here, as I would really like to try it! -

I wish that the make up shops Douglas and Ici Paris here would start to sell it too. I don’t like to buy color cosmetics online (unless I know exactly the numbers I need). I would like to try it! -
In answer to the pm’s I received about i.a. the accessories (not the raw ingredients): these (and the empty tubes + boxes) I have bought from AliExpress.
(The raw ingredients come from different (DIY) suppliers, Ronaflair Flawless is sold by Alexmo Cosmetics, Germany).

@Sponge
Thank you very much for your help!
The Mg stearate mostly for slip. The pigment phase of 33,3% is 50/50 pigments/C12-15 Alkyl Benzoate (as wetting agent/dispersion vehicle). So it’s about 16% pigments. Is that still high to begin with? I had hoped I could raise it quite some more! 😉I didn’t have any problems with this pigment level luckily!
Do you think I should change something?@ngarayeva001
Thanks :kissing_heart: -

Ok thanks! -
Particles from a spray bottle are much bigger and heavier than those from an aerosol, so are less likely to linger in the air, thus less likely to be inhaled/ingested. I think this is the reason that only aerosols are mentioned in the USA/Japan warning.
I agree it’s very confusing that your supplier states that it can’t be used in sprays either. You could ask Ashland (manufacturer of Liquid Germall Plus) about this to be 100% certain?Liquid Germall Plus does indeed contain a formaldehyde releaser (the diazolidinyl urea). It’s safe to use as recommended though. Any substance can be toxic (even pure water), it’s all dose/concentration dependent. The amount of formaldehyde that will be released is low enough to be classified as safe for preservative usage in recommended preservative concentrations.
Remember that the formentioned warnings do not count for the formaldehyde releaser in the Germall, only for the IPBC.Good luck with your projects!

Thanks a lot for your information! I’ll do some experiments. -
@BeardlyGentlemen
Ok, confusion solved.I think it’s best if you post the compete formula of the pomade. It’s very hard to say anything without knowing more details.

Thanks so much for all the information!
Glad that the lotion fail happened, now I’ve learnt a bit more! -
@Dynamin
Coincidentally I’ve just arrived at this chapter in a cosmetic handbook that I’m reading. I can try to copy the chapter if you like? (It also mentions vitamins and Minoxidil btw) -

So the temperature of around 38C has increased the rate of the hydrolysis reaction?
That must be the reason why I’ve never had this happen before with both allantoin and NaOH in a formula, I always alter the pH at the very end of the process, at room temperature.Much obliged! :+1: :blush:

Thanks for your answer and explanation!One more question if you don’t mind:
What if I add the allantoin (in solution) later on in the cool down and I need to adjust the pH just a bit more?

Thanks for your reply.
Do you think that 0.5% allantoin is a lot? I’ve never had 0.5% allantoin recrystallize over time even without betaine? What would you say is a ‘normal’ amount?
It’s so weird that I use allantoin all the time in the heated water phase and neutralize with a NaOH solution (in the end of the process). I will be more cautious next time! -

I am planning to do a few experiments and that is indeed one of them!
Thanks for thinking along with me! :+1: -
pH of a lipstick? Or do you mean a water containing lipbalm (with a creamy consistence)?
A waterfree product has no pH, so there’s no pH to measure. -
@”Dr Catherine Pratt”
“…and really I am talking to the chemists that get loads of free jobs”
Then why do you send me of all members a private message? I’m surprised to see that you’ve actually even read one of my threads, the few ingredients that I use in my tiny 150 gram batches. If you’ve read those a bit better, you could’ve known that I’m not a chemist, but a ‘simple’ homecrafter.
And apparently not worthy of the space on this forum.
Ever heard of a chemist using a stick blender? Or a chemist saving money to get challenge tests done on a few formulas?About Chemist Corner. It’s indisputable that Perry has done and is doing a magnificent job with this CC forum and everything else, the courses, the CC website, The Beauty Brains website. I have nothing but the utmost respect for him. But what I donate is really none of your business. Neither am I interested in the donations you make.

@Microformulation
In the end, these are NOT raw materials for a novice. If in fact any real absorption was accomplished to any area other than the uper layers of the skin, it quickly becomes a drug NOT a Cosmetic.In the end, it is highly doubtful that you will get any real absorption of the actives NOR should you.I totally agree!
(I didn’t mention the DMSO as a tip to put in cosmetic formulations, I just mentioned it as the only penetration enhancer that I personally know of.) -
Where are you based? The aerosol warning is for the IPBC in the Liquid Germall Plus and only counts for Japan and the US. Europe has other rules regarding IPBC, but I don’t read anything about aerosols or sprays, only a lower allowed concentration for deodorants/APs:
“Regulatory profile IPBC:
USA: Approved in all applications with the exception of aerosols.
Europe: For rinse-off products, a maximum of 0,02% is allowed. For leave-on products a maximum of 0,01% is allowed, except in deodorants/antiperspirants where the maximum is 0,0075%. Not allowed for use in body lotions and body creams. Not allowed for use in oral hygiene and lip care products. Not to be used in children < 3 years except in bath products/shower gels and shampoos. If used in products other than bath products, shower gels or shampoos, the following warning is required on the package: Not to be used for children under three years of age.
Japan: IPBC is approved at 0,02% in all cosmetics. Not to be used in aerosol products.
Maximum recommended use level of 0,5% Liquid Germall Plus in a finished formulation results in 0,002% IPBC concentration.“
I think that the reason behind the spray warning (whether an aerosol or not) is indeed inhalation or ingestion of IPBC, this way you’ll be exposed to a relatively higher concentration than only topically, on the skin (note the lip care/oral hygiene warning for Europe).
But as you can see, even the maximum recommended use level of 0,5% Liquid Germall Plus results in a very low dose of IPBC, even way lower than the 0,0075% deodorant max for Europe. -

MemberFebruary 17, 2019 at 10:53 am in reply to: Sensitivity electrode of refillable pH meter@S_AlAhdab
You mean that the electrode itself has dried out? I don’t know for how long, but given the fact that it didn’t measure right, it seems it’s beyond ‘repair’.At work we have the same problem, some people seem to fail to see the importance of placing the electrode back into the storage solution, so every once in a while there’s a dried out electrode that needs replacing.

Dimethylsulfoxide/DMSO is the only penetration enhancer that I know of, we use it as extravasation antidote.
Liposomal skin actives are said to penetrate deeper into the dermis. I just read an article about the quality of liposomes, those of a less quality not penetrating at all. I’ve bought Rovisome CE Plus a while ago, with vitamins C and E in liposomes. Haven’t used it yet and I don’t expect much from it, but I like to experiment.

I wouldn’t know of a way to increase gel viscosity and keep the same texture besides raising the level of carbomer, I’m afraid. Perhaps other members can be of assistance to you.
Good luck! -

MemberFebruary 17, 2019 at 10:14 am in reply to: Preservatives without Coconut and Palm (Allergy Reasons)I’m sorry to read that the phenoxy in Phenonip is coconut derived.
Maybe there’s another way around this. Do you know if all phenoxyethanol is coconut derived?
Instead of a blend, you could get the ingredients of Phenonip seperately. In the country where I live, there fortunately is one DIY supplier that sells methylparaben, propylparaben, phenoxy, benzyl alcohol etc. etc. as individual ingredients as well. Although I mostly use blends, it comes in very handy sometimes to add a single or two parabens to a tricky formula, or to lipstick.
Optiphen PO (Ashland) for example is only phenoxyethanol. Schülke has methyl- as well as propyl paraben. You can search for manufacturers on UL Prospector.I really hope that you cand find a solution to your problem. If anything comes to mind again, or if I read something, I’ll alert you.
Best of luck!
