@Perry but I guess the spicy pizza can be a good cleanser for intestines

[Chemist77]

@Robert why yesterday only I was on this forum where someone raised a query and the other one commented that the guy is trying to extract free info, strange people with stranger thinking.

[Chemist77]

Well then start formulating and I wish you have a good one on that

[Chemist77]

I am not sure how you gonna formulate it, for a silicone serum we use generally upto 10% to build the viscosity alongwith DC 1501, but  this is more on hair care side. From this you can take a leaf and formulate accordingly, if you want to just have it in formula then keep it to max 3% coz more of it can create tack. To reduce drag try to optimize between cyclomethicone and DC 200 1000cs

[Chemist77]

Thats a good decision indeed, though u can melt 3-5% petrolatum in any light ester oil, I dont  think your skin would need anything else whole winter. 

[Chemist77]

oh ok this is what you have. Re the first one I guess he has used high viscosity Dimethicone (there are many grades ranging from water thin to almost jelly) with cyclomethicone, you can reduce the tack and drag of high viscosity dimethicone by optimizing the ratio and still have a viscous consistency. Rest of the things we all know are for namesake, and if you see so many oils then many of them are carriers for the those namesake actives probably. 

In the second one he has used DC 1501 (Xiameter now) and rest of the oils are to stretch the ing list otherwise the main ingredient is DC 1501. It is a gum dispersion of dimethiconol in cyclomethicone and itself carries some viscosity. 

Hope it helps. 

[Chemist77]

If you thicken your serum it would give you drag and tack on the skin, better to keep it thin and easy to apply. Won’t be a bad thing either, if it is for your ownself.

The gellants from Ajinomoto might work perfect for you but they are a costly affair and have to be used in sync. It would be around 100 euro a kg for each of them.

[Chemist77]

Or try Sucragel grades, that might work too. 

[Chemist77]

I have seen few like linkedin and others but trust me I am yet to hit on a more user friendly and responsive forum than this. 

[Chemist77]

Try versagels or there are 2 more gellants from Ajinomoto namely EB 21 & GP 1. The ones from Ajinomoto are costly but eonderful but I guess in your case you csn use versagels too. Or the cheapest one is Aerosil grades, only dispersion is a bit tricky.

[Chemist77]

Dear Perry,

I have been to other forums too but I feel even novices like us too can feel comfortable among the learned bunch. They talk in a language which is understood by all and sundry and the good thing is that yet the technicalities are never skipped. 

Great job, keep it up.

 

[Chemist77]

It works within a pH range of 3.5 to 10.

[Chemist77]

think upto 5 it should be ok, below that you would have to use with carbopol aqua sf 1, still read literature for all 3 for the best choice.

[Chemist77]

very good link Vijay

[Chemist77]

I have some from Sina Ekato, but choose wisely.

[Chemist77]

Try using PEG 150 Distearate, it builds up good viscosity. Then there is Arlypon TT as well, a popular choice these days.

[Chemist77]

@Kitty I am sure Duncan can give you some valuable inputs on this one. 

[Chemist77]

Just a dimer of Glycerol, more viscous (so maybe less thickener needed), mild humectant and enhances fragrance stability and longevity (but not a hard core on this one). 

Likewise there is a very famous cousin of MPG (mono propylene glycol) called DPG (dipropylene glycol) which is one of the main carrier solvents of a major chunk of fragrances. . 

[Chemist77]

@pma if you are not looking at viscosity which is one of the most important parameters for us then life is a bit easier on development part

[Chemist77]

I use Na Cocoamphoacetate with few other things like lauramine oxide and a polymer thickener, have nice foaming, clarity and good afterfeel.

[Chemist77]

Nice one there.

[Chemist77]

I don’t understand, no matter how much the aeration is, if it is a single phase (aqueous) product, I am sure the aeration should go away. But without knowing the full formula ingredients it is very difficult to suggest. 

[Chemist77]

Then heat separately and add, think that would be the best way for you. 

You can add PEG-150 DS in hot water too but the stirrer should be on and the material should go directly into vortex to avoid clumping or sticking to the wall.
