SCI isn’t readily dissolvable in water. That’s why no one used it as primary surfactant in a conventional shampoo. What would bother me the most with such creative concept is how to preserve it. What the final ph is going to be with all that bath bomb combo?
-
It’s not necessarily 70, it’s the melting temperature of the material with the highest melting point. Behentrimonium Chloride is 90+. I would not rely on the source you provided above.

It is better to use combined methods for sulfate-free shampoos. For example, adding CDEA, Polyquat 10 (it has gum properties) and Crothix Liquid. For easier cases, Crothix alone would be sufficient. Crothix is liquid and is easy to work with

Without chemicals? That’s super easy!

It is light, but you need 3-5% for a lip gloss, which means that even if you make just 30gr scale with two decimals will register it. It doesn’t work with polar oils btw. Or shall I say, the one I have (covasilic 15) doesn’t thicken polar oils.

@Beryl01, for the very same reason a class of products such as eye creams exists: because companies want consumers to buy more. There is no difference between lotions and creams but viscosity. Low viscosity = lotion, high viscosity = cream. I know liquid water-based products that are called “lotions” and runny emulsions that are called creams. None of it is neither defined nor accepted commonly. You can use one product all over your body.

By the way, getting back to the preservatives, although I think Sodium Benzoate+Potassium Sorbate is a bad solution, as the pH might shift, PE9010 alone will not be enough. My bad, I said above it is. There are plenty of broad-spectrum preservatives that are sold by repackagers.
Perry is co-running course with Swiftcraftymonkey and Makingskincare. Makingskincare has plenty of good information including this article on preservatives which could be useful.

I know that betaine slightly helps in dissolving Salicylic Acid (still a nightmare to dissolve). I haven’t read anywhere if it helps to dissolve allantoin but it is worth trying.
-
Lotions are damaging? Why?
-
Have you send an email from ‘gmail’ or from business email? If the first it might be the reason. Also you need to specify that you are planning to buy in bulk, otherwise they might not take you seriously.
-
If you are making it for yourself, remove claim materials that are bug food and PE9010 alone is enough. Too much betaine, too much allantoin, it’s solubility in water is 0.5% anyway. Keep in mind gluconolactone is sticky on its own, don’t add more sticky materials.

There is also this blend https://cosmetics.specialchem.com/product/i-gfnselco-specped-lash-ld
there is some evidence although not very strong -
https://www.glamourcosmetics.it/gb/hectorite-gel they have international delivery. pretty good for colour cosmetics. I use it in foundations.

I really like this site https://incidecoder.com/
Please ignore their comments on how good or bad is the ingredient. I am sure they mean well but unfortunately, it’s not as simple as calling an ingredient “goody” or “icky”. Other than that they often provide great easy to understand descriptions (and sometimes even brand names of the INCI). They also show in which commercial products ingredient is found which I believe is very helpful in analysing how it’s used. -
I think PEG-7 Glyceryl Cocoate is a better re-fattening agent than Glyceryl Oleate but that’s my preference.
-
That’s not how it’s done. Post an entire formula with %, explain what function you are looking for and ask what can you use to replace Seteareth 21.

Never rely on google for scientific research. Whatever ingredient you are going to search the first three links would read “10 toxic ingredients that you should avoid in skincare”. Those links would take you to questionable resources, such as guardian, to nonsensical articles written by dilettantes with no scientific background whatsoever (but who probably would have other “important” credentials such as being a feminist campaigner) who would be throwing wrongly spelt INCIs at you and calling perfectly safe ingredients “dirty” whatever it means in their delusional mind. The skincare market is highly regulated. PEGs are safe. Silicones are not only safe but environmentally friendly (with minor caveats), mineral oil and petrolatum are great skin ingredients as long as they are properly refined (just check if those are ok for cosmetic use). Parabens are safe too. Do you know what isn’t safe? “Natural-wonderful-healing-soothing” essential oils.

If you paid for this formula you should demand a refund. Here is what is wrong with this formula:
1) Hair products do not need oils. All the oils you see in commercial products are added at a min amount for label appeal. Cut oils to 0.5% or even less. As long as you have a drop there you can say it on the label.
2) Too much of vitamin E. You don’t need more than 0.2%
3) 0.25% of cetrimonium chloride isn’t enough to emulsify 8.5% of oil. Keep it for conditioning and add a non-ionic emulsifier. Ceteareth-20 will do (GMS+PEG-100 Stearate is another option). How much depends on the amount of oil and Cetearyl alcohol you are going to keep.
4) In a properly emulsified product, 4% of Cetearyl alcohol won’t stay liquid. Cut it to 2% if you want to maintain low viscosity (try 1%, 1.5% and 2% and see what works for you).
5) Sodium benzoate alone is not enough to preserve this product. It’s not a broad spectrum and it requires low pH.
6) They should not suggest a precise amount of citric acid. Citric acid is qs to pH of XYZ. In this case, your pH should be not higher than 5 because of your preservative but I think you should replace it with something reasonable. At least Euxyl PE 9010. -
I noticed that polysorbates can lead to a decrease of viscosity when added to shampoo. The caveat is that I only observed that in sulfate-free shampoos.
-
If it’s cold process I start making shampoo from premixing fragrance in olefin sulfonate. I noticed it’s much better in solubilising EOs than any other surfactant I work with. Better than SLES. Depending on type of EO, product might even stay clear.

Good quality french high altitude lavender is so different from bulgarian that it’s hard to believe they have anything in common.

You can create W/O emulsion with water phase less than 15% and O/W emulsion with an oil phase more than 85%. It has nothing to do with the amount of oil and water. You chose the type of emulsion based on the product. Majority of foundations and some sunscreens are formulated as W/O. Some high-end face moisturisers also formulated as high internal phase W/O. W/O are hydrophobic, so when you want to get this quality, you chose W/O. I haven’t seen hair products formulated as W/O, my attempt to create one wasn’t particularly successful. The pomade above is O/W.

Are oils dispersed physically within the gel network here?

Probably it adds a little bit of a slip but I am not sure you can mix it with xanthan or Zen..
