Swiftcraftymonkey has a booklet on syndet bars. You can purchase it for 20 Canadian dollars. Totally worth it in my opinion. However I don’t think that syndet is what you need for sensitive scalp. They are rather concentrated. Also you mentioned you would like to make it without preservatives. Do you know which preservatives cause sensitivity in your case? My point is, maybe you just need a well formulated mild shampoo preserved by parabens instead of ‘natural’ fluff?

You need powdered surfactants such as SLSa, SCI (about 70%) waxy emulsifier (say BTMS), you can use stearic acid to make it harder (but it will be draggy). And you absolutely need sodium lactate. It makes bars harder.
-
Responding to the question: yes. Details?
-
@Belassi in da hous!!! I always appreciated your humour but this is the best of all. I am stealing this picture.
-
This is also wrong labelling because in the US (and EU) one is not supposed to list the brand name of the emulsifier but its INCI.
This makes me think that the LOI is not compliant with regulations and not correct. A moisturiser made with the ingredients listed is not going to have a nice texture (stearic, NF…). They used aloe juice instead of water, and no chelators, antioxidants and preservatives. If this LOI is true, this product has a shelf life of two weeks. -
- W/O is not for beginners.
- O/W mix togeher and apply high shear. Temperature depends on materials and there is no one size fits all rule. -
MAP isn’t easy to work with. It also reduces viscosity of polymers. I think you should change an emulsifier.
-
I see water and oil and don’t see emulsifiers. Or I missed something? Also 40% of butlene glycol?

This is an endless topic on the pros side. First of all silicones are quite wide range of ingredients. High cps dimethicone reduces TEWL, volatile silicones in duo-phased make-up remover act as functional ingredients (they dissolve makeup), some crosslinked silicones can be used straight on face as primers and enhace texture of the product in general, silicones reduce soaping caused by surfactants, silicones in hair care products add shine. The bottom line - silicones are amazing.
Cons - chemophobia…

@ShellyJ, I don’t have experience with color cosmetics, but I ordered from this a couple of times, and noticed this recently. Translate the page. I hope it’s what you are looking for:
-
You need cationic ingredients. Replace emulsifiers to BTMS 50 and add polyquat 7 or 10.
-
I don’t know what to say here… I have experience with over 100 ingredients (oils and esters excuded) and already experimenting with water in oil which isn’t for beginners but I don’t think I am experienced enough to mess with AHAs. It’s not a good idea to encourage someone to make 10% toners at home. Products with concentration over 30% can only be used at dermatologist’s office.
-
I am sure they sell the same model in the US. Don’t buy 220w devices. They don’t work in the US properly.
-
Post a formula…..
-
This one made me cringe: https://www.theguardian.com/commentisfree/2019/jan/08/carcinogens-cosmetics-brexit-britain-eu-makeup
Leaving means losing stringent EU rules on hazardous chemicals in makeup in favour of opaque US-style self-regulation.
I don’t even know where to start but I wish it was possible to sue both the author and the newspaper for such misinformation. -
@Perry it would be nice, but I am (and many others) gratefull chemistcorner exists even without such extras. Belassi’s humor is priceless though.
-
@enzinhoo, what is it exactly that you asking? A free formula or formulator’s advice? Whatever it is, you are not going to get it with such requests.
-
We need ‘like’ button for @Belassi’s comments
-
Swiftcaftymonkey’s formulas (when done exactly as instructed) always work for me. My problems start when I start playing with surfactants
Are you using exactly the same formula as she provides in the ezine? -
Moreover, the formula above minus decyl glucoside will have pH below 7. Fantastic product!
-
@Belassi, this is a beauty of syndet bars - they are very “forgiving”. You can combine cationics and anionics together and it works. The main issue is how to make them harden. Sodium Lactate is the deal breaker.
-
sci 30% - ok
slsa 28% - 35%
capb 10% - 22%
decyl 5% - you don’t need it
btms 3% - ok
cetyl 5% - you don’t need it
stearic - it makes shampoo draggy. you don’t need it
Emulsifying wax nf 7% - You don’t need it
panthenol 1% - ok
Aloe extract 1% -ok
fragrance 1% - ok
essential oil 1.5% - too much
preservative .5% - are you sure it’s enough? what preservative?Add:
- Sodium lactate 3% (must add, it makes bar harder)
- Poliquat 10 - 2% (good to have but optional)Try to have 70% of dry ingredients (approx)
-
@Belassi, sorry just to confirm that I get it right, I thought most of cyclomethicone in the market is a mixture of d4, d5 and d6. If d4 and d5 are going to be banned, does it mean that what is commonly called cyclomethicone will be banned all together?
-
Hydrosol is a bug food. It doesn’t add any benefits but the smell.
There is much more to it than “combine the water soluble ingredients in the water phase, oil soluble in the oil phase and then an emulsifier and force put them together into an emulsion”. My advice, go to makingcosmetics and look at the types of emulsifiers. And then research each type.
