  • replacement for peg-12 dimethicone

    Posted by komirra on December 19, 2016 at 7:21 pm

    Hello!

    I am trying to duplicate the amika rx triple shampoo, but i dont have peg-12 dimethicone. the closest thing i can find on the web is peg-8 dimethicone from makingcosmetic.com. is that a viable substitute? what is the difference between them?

    I also have water soluble shea butter, could that be used instead of peg-12 dimethicone sense they are both emollients?

    LOI
    water (aqua), sodium c 14-16 olefin sulfonate, cocamidopropyl betaine, glycerin, disodium cocoamphodiacetate, peg-7 glyceryl cocoate, glycol stearate, fragrance/ parfum, sodium methyl cocoyl taurate, hippophae rhamnoides (seabuckthorn) fruit oil, persea gratissima (avocado) oil, hydrolyzed keratin, hydrolyzed wheat protein, chamomilla recutita (matricaria) extract, rosmarinus officinalis (rosemary) leaf extract, lavandula angustifolia (lavender) extract, butylene glycol, polyquaternium-10, peg-12 dimethicone, polysorbate 20, peg-150 distearate, citric acid, disodium edta, methylchloroisothiazolinone, methylisothiazolinone

    The PEG-12 dimethicone is present in a very small amount. I haven’t used either of these as a water-soluble shampoo component but I would not think there is a huge difference between them. If the LOI is in correct order there seems to be a lot of PEG-7GC in there.

    I already have peg-7gc. I was thinking that the peg-12 dimethicone would add some slip to the formula, which would be benefical for thick curly hair

    Won’t be worlds apart, surely you can give it a try since it’s just a difference in ethoxylation only.

    I see that you often reccommend lamesoft PO 65 alot for hair products for dry hair and skin. would just getting the glycerl oleate by itself, which is easier for me to get have the same effect?

    I don’t see why not, in fact as far as I’m concerned it is preferable because I do not like glucosides. Try it between 0.5 - 1%
