  • Can I sub Cyclomethicone for Dimethicone to reduce soaping in lotion?

    Posted by Graillotion on April 26, 2020 at 2:25 am

    I am trying to wrap up a (mostly natural) lotion formula… mainly selecting the emulsifier.  So far the one in the lead is a product from Floratech, called Emulsun.  Super easy to work with (PEG free), and really holds things together well. (It also has the benefit of being one of only 3 emulsifers that will hold my mosquito lotion together…. a completely seperate project.)
    The only negative has been an increase in soaping.  I know that dimethicone has been the go to product to reduce soaping….so my question basically is:

    Since I only have cyclomethicone on the bench…is that a reasonable alternative?…. Or should I add a week to this project and order the dimethicone.

    I would prefer not to use a silicone…as a soaping reducer….so let me also ask…are there any more natural alternatives?  I have read many old posts…and have seen the following pop up…. cetyl alcohol and Isoamyl laurate.  Any thoughts on these?  (I did already have 2% inclusion of cetyl palmitate in the formula.)

    One more thought….in those old posts…I also came across a comment….about xanthan gum not being very compatible with sodium hyaluronate…..(creating a negative sensory experience).  I had never heard this before, and I include both in the formula.  Anyone else agree….or disagree with that comment?

    Hi. I would also like to ask, if cyclomethicone can be used instead of Dimethicone to reduce soaping.. also what concentrations would be advised?

    You mean D5? It depends where you are located. Its use is restricted in many countries. My thoughts are, that D5 would slowly evaporate from a leave-on due to body temp so, in a repellent, I doubt that you want the repellent partially evaporating. Or who knows, maybe D5 vapour is a mosquito repellent? You might become bigger than OFF, one day, I will be sitting in my Old People’s Making a coffee in a 500mL Pyrex beaker, and I’ll see you in the news, the man who made OFF obsolete.

    I forgot to mention: I use D5 in a skin cream. I reverse engineered an Ev&Crab product.

    I just looked up my formula for you. cyclopentasiloxane, 0.25% and dimethicone petrolatum, 0.25%. The d.p. is a Polytrap powder, one of my favourite ingredients. The D5 acts as a solvent for the Polytrap and later evaporates leaving the petrolatum/dimethicone film on the skin, it’s unbeatable for TEWL and gives great sensorials. But for a repellent, I’d leave out the d.p. and maybe use 0.3 - 1% of D5, you will have to experiment to find the optimum.

    Hi Belassi! Thank you so much for your kind reply.. yes, I believe it is D5- my apologies, I am a relative newbie.

    I’m making a light moisturiser and I have been having issues with the dreaded soaping… I have been recommended to use 2-3% Cyclomethicone (D5) in my mixture to stop this.. (in the absence of Dimethicone)
    I have also read that using a low HLB emulsifier would help (??) At the moment I am using a proprietary Glyceryl Stearate/Peg 100 mix (it comes 50/50 mixed already).. I am considering adding 2% pure glyceryl stearate to help remedy this..

    Any thoughts would be greatly appreciated!!

    HAHAAHH!! I’m not sure I will ever reach the exalted heights of making anything obsolete- but if I do, I will be sure to visit you and buy you a Nespresso machine with matching bespoke pyrex beaker!!!
