It’s often called ‘synthetic lanolin’ or ‘vegan lanolin’ Great ingredient. It’s sold by alexmo https://www.alexmo-cosmetics.de/Softlanae-649-veganer-Lanolin-Ersatz

Have you checked iodine value of these oils? I recall pomegranate is very high. Tocopherol obviously helps but it can only do so much.
-
i am not an expert on preservatives. the safest way is to use ready blend. phenonip for example.

polyquaternium-10 inci includes a variety of different products. some are more cationic than others, so there is no simple answer.
-
and methylparaben alone isn’t broadspectrum
-
In this case, it’s a crucial part of emulsification system. Do not cut it as it will compromise emulsion stability. TEA-stearate emulsions are always above 7. Probably it’s 8-8.5 but that’s typical for this emulsifier.
-
combination of ingredients is fine, probably something is wrong with %
-
Sorry if it’s considered off-topic, but does anyone know why ethoxydiglycol is restricted to rather small amounts in EU? I only found some papers mentioning kidney toxicity but no details. I am using it at 30% in CE ferulic serum (got inspiration from L’Oreal’s patent for personal use), and it’s ehoxydiglycol that makes it feel ‘right’.

@klangridge, polyquaternium 10 can be very different. some are more cationic, some are less.
-
@Abdullah, polyquatermium 10 can increase viscosity slightly. But it depends on what else is in the formula
-
Amodimethicone might impact viscosity. I think sticking to pq10 is safer.
-
The problem is, it’s almost impossible to tell. Polyquaternium 10 is like carbomer or xanthan gum: comes with different properties but INCI is the same. As per my anecdotal experience polyquat-10 tends to impact viscosity less.
-
Sepinov EMT10 will thicken at 4. Sepimax Zen at 3 (I want to say 2.7 but my ph meter isn’t the most accurate).
-
Polysorbate 80. Cheap and very easy to find. Also tingles eyes less than cithrol 10 gtis. Make sure you use high polarity oils and waxes, or it will separate.
-
i haven’t worked with azelaic acid, but I highly doubt it’s niacinamide. Are you using solvents?
-
To add to previos comments,Tetrahexyldecyl ascorbate is oil soluble and will perform better in oil based product. Although it is more stable tha LAA it still oxidises in presence of water.
-
Thank you for the answer
I reduced ph of a conditioner (with behemtrimonium chloride) with citric acid without visible issues before, but since I don’t run my formulas through stability tests I can’t know for sure. -
@chemicalmatt may I please ask you to explain (or point me in a right direction for further reading), what’s the deal with cationics and citric acid? I noticed that many commercial conditioners contain lactic acid instead of citric and I never understood why.
-
@Graillotion, they probably just threw some hydrogenated vegetable oil in it.
-
W/O are tricky and emulsifiers should be paired. Emullium Illustro is a good option. Can stabilise relatively high oil phase and it’s already a blend.
-
Panthenol and extracts are waste.
-
This question has no answer. A shampoo made of what? If you are trying ti dilute ready product with water it’s a bad idea for multiple reasons.
-
Hydrogenated polyisobutene would work anywhere where squalane does. I use it as an affordable squala replacement. Also it’s non polar, which means better stability, and versatility.
-
It’s extremely tricky. You would need emulsion to be stable and zinc oxide must be coated and you need additional ingredients that help with dispercing pigments (polyhydroxystearic acid, disteardimonium hectorite etc). Depending on the coating, pigment goes to either water or oil phase. The question is, what benefit are you expecting from zinc oxide?
-
what do you want it to do?
