By the way it’s not true that cosmetic ingredients aren’t regulated. If INCI says 99% triethanolamine you know for sure it’s exactly that (provided you are buying from a reliable supplier). Food supplements don’t have an equivalent of INCI, they can put whatever bulking or anticaking ingredient there and you wouldn’t know. Good suppliers provide SDS that gives a lot of important details.

Yes, betaine is very easy to work with. Dissolves in cold water. I used it but it is not my favorite humectant because there’s nothing special about it. I prefer sodium lactate, it’s more hygroscopic than glycerin (smells a bit weird though). My second favorite is butylene glycol (non tacky and a preservative booster), and third is glycerin probably. It really depends on the product I am making. I guess if I could only have one humectant it would be glycerin.

Have not tried it myself but I like this supplier. Use google chrome translate function. They ship internationally https://www.glamourcosmetics.it/gb/xylitol

https://www.glamourcosmetics.it/it/betaina-anidra-trimetilglicina
I bought from both places. I don’t think it’s anything special though. -
Are you referring to the product separating of not being long lasting when used? Hard to tell without a formula.
-
Urea will break that sodium carbomer. You need to find another gel maker. I think xanthan is the only thing that might work here (still not sure with 6%).
I also think you have too much of everything in that formula. I would get rid of proteins and quats. -
Glamourcosmetics.it. They should ship to the US.

I can’t stop getting surprised how huge is effect of marketing. I make a simple hair serum and I gave it to a friend to try. Nothing unique but I selected good materials I believe: dimethiconol in D5 (Dow’s ingredient), phenyl trimethicone, some fragrance etc. The friend wasn’t very impressed, which is fine, everyone has different taste. She sent me a link to ‘the most fantastic hair serum she had ever tried and her hair dresser raves about it too’. Product by Kerastase. I opened the LOI: Cyclopantasiloxane, dimethiconol…… I went to a drugstore to try it (because who knows, % makes difference). Very similar to mine. But mine didn’t say Kerastase.

@letsalcido there’s no like button here so have to tag you <LIKE>

It’s unpreservable and have no benefit.
-
It also deactivates some preservatives. Is there a particular reason why you use it as co-emulsifier? There might be good alternatives.
-
@Sponge, you are right, the one sold by tkb is propyl https://tkbtrading.com/products/flake-resin
-
Don’t forget to add refatenning agents, pearlisers (if need opacity) and cationic polymers too.
-
Then try to find Sodium Lauroyl Methyl Isethionate, Sodium Methyl Cocoyl Taurate (I haven’t seen oleoyl anywhere) and CAPB. For a mild shampoo, you want to keep ASM within 15% and keep amphoteric relatively high. That combination is mild yet foams okeish (you can’t have it all, unfortunately, the foam will be dense no large bubbles). I would say someone with oily scalp might not even like it because it’s too mild. I use that combo for a facewash.

@Perry shared this article some time ago in of the threads started by me https://www.dropbox.com/s/fuuig4f3p3fwxmd/heat-damage-to-hair.pdf?dl=0&fbclid=IwAR3guJlqfx4ebTqfEs_jntunWu-iT5bb71BmoZACZFHel-SNtYFRGq7qD4A
In summary, it’s not that easy to quantify damage to conclude that the product works. As per my quick research, most heat protectants on the market contain conventional ingredients such as PVP, Behentrimonium Chloride, various cationic polymers (i see polyquaternium 47 a lot but I have never tried it) and obviously silicones. If you want to avoid silicones because of customer perception I think the best way would be to see what is advertised in Personal Care Magazine. https://www.personalcaremagazine.com/story/20118/a-natural-solution-for-healthier-hair
https://www.personalcaremagazine.com/story/19990/a-natural-solution-for-healthier-hairNo guarantee that those materials would work, because those are articles by suppliers (and they are definitely not independent) but good enough for a story.

No you can’t replace it by any of the listed ingredients. It’s a film former with water resisting properties. It can potentially be replaced by trimethylsiloxysilicate, although they often come in a blend. Both are sold by tkb trading, makingcosmetics and glamourcosmetics.it. If you decide to get pure ingredients you would also need a proper solvent (cyclopenhasiloxane would work).
-
Absolutely agree. It’s not that hard to master O/W moisturizer but a surfactant products are tricky.
@Belassi, I have occasional failures and I use them as floor washing liquid. Provided that I never run out the failures happen more often than I would want. -
It’s probably shear issue. How do you emulsify it?
-
Decyl Glucoside is far away from mild. Look into Iselux or Iselux Ultra Mild if you can find it.

There are polymers with some heat protectant claims (by suppliers), which I doubt you are going to find on the DIY market.
-
@chemicalmatt, I might guess you were not interested in skin lightening products. This scale is mentioned a lot in a context of which ingredient is better for different types. Like alpha arbutin is claimed to be more effective for types I-III and kojic acid for IV and above (if I remember correctly). Also referred when it comes to sunscreens.
-
Some varieties of polyquaternium-10 create gum-like viscosity (they vary a lot btw, always test). But there’s something I find a bit surprising in this shampoo, amphoteric goes first and SCI is high up. It’s rarely used at a high % in liquid products.
-
Silly question maybe but why wouldn’t you use a stick blender? I know there’s a stigma about using stick blenders among chemists but they are cheap, can deal with high viscosities and do the job. You absolutely need an overhead stirrer in my opinion (especially if you make w/o) but stick blender is a budget friendly option when you need high shear. There are versions that are >15,000 rpm

@amitvedakar, that blend isn’t bad but it’s white. If the transparency of the product is important, you might want to consider other blends.
