Hello,
I am Helen and I live in Canada. I have a very specific skin sensitivity and the care products that seemed to be working for me were always on the expensive side so one day I decided that I would try to formulate and make them myself. My background is in Biomedical Engineering but my chemistry knowledge is very dusted as I have migrated to technical sciences over time and of course I had no formulating experience at all. I was glad to be able to post a few questions on this forum three years ago and with the kind advice I got I was sent on a path that has developed to a passion since then. I have learned so much and I keep learning from all the wonderful people who unselfishly share their wealth of knowledge and experience. Thank you all and thank you Perry for creating and running this site !

Thank you so much !

Thank you very much for this list !
I would like to use Methyl Gluceth-10 in my formulation. It is supposed to be water soluble but on the supplier’s site they say “Add it to the oil phase.” I am confused
. Where would you add it ? -
Thank you I will try that too !
-
Thank you Belassi - so it is for environmental concerns, not any controversy over usage in cosmetic products. I will be producing about a cup of the moisturizer per month so hopefully not many fish will die

Oh I was just making fun. I know there is much more. I am already looking at the site you recommended. I did not know about it, it is great !
Talking about bug food …..don’t we all eventually become worm food anyway.
I use the hydrosol for the smell only, I know it is scented water basically but it gives a fragrance to the product. I will eventually try to add fragrance - it is added to the completed product right ? -
Granted. But I am only creating this for myself in tiny batches and even if I buy the most expensive ingredients, the 100ml of product that lasts me a month would cost a fraction of the market price. But I like truth in science so de-mystification is definitely no disappointment
The first thing I made myself was the HMW HA gel serum using Neroli hydrosol in place of part of the distilled water which gave it a nice scent and I was so happy with the ease of making this that I decided to learn more and say goodbye to Sephora like places… I bought a couple of those air-tight containers and it makes me smile when I know that the most expensive part of something I make and enjoy is - the container ! I only have the lab precise scales, a few beakers, a thermometer and a dedicated stick blender, ph test strips and a zest to learn. I share a batch with a friend so that it is spent soon and we do not need to keep it for long.
But now I needed advice for how to work with the silicons so I came here.
Thank you again !
From what I understand - the very simplified principle for creams is : you 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. And they you work on how thick they should be and other properties you want ..etc..And you can do it with heat or without correct? For the silicons it is without the heat right?
I must sound like a kindergarten child to you …

Seems Sucrose Stearate is not easy to get by in Canada though….
-
Thank you I will try that too !

Thank you ngarayeva , thank you so much! You are awesome ! I will post the result . If this works I will be one happy camper. And yes, I know the “ actives” are in most cases just for the advertising …, it is the hydration of the skin by HA that actually counts. Thank you also for the explanation of the missing link.
I will keep learning - the book on Silicones that Microformulation sent the link for is beautifully written and even pwople like me who have forgotten a lot of the chemistry can enjoy reading.
Thank you Belassi for your respose, I understand now. Why is D5 restricted in Europe?
-
Thank you !
Being an expert in a different field makes me humble enough to realize my incompetency in others . I read the entry on Silicones posted on the blog of this site by Perry Romanovski as a start and will certainly keep reading and look at the Shinetsu info.
I am trying to formulate this just for my own use so the question of what benefits do the silicones bring to the table has been already answered - I love the consistency of products that contain them.
I believe a genetic disposition makes my epidermis somehow “impermeable” for a multitude of ingredients and if I use any facial product containg oils, I can literally wipe the entire layer off my face hours after application. Silicone based products work for me. So I would like to make my own ones if it is possible.
Thank you again for your support ! -
The benchmark product is the Water Drench Hyaluronic Cloud Cream Peter Thomas Roth, but I would be happy with just a similar consistency. My idea was to try to somehow join together the HA , which I have as a powder and the Cyclomethicone which is in liquid form and then add the Dimethicone which is a paste . But then I thought that maybe if I make the water based HA gel (serum) with all water soluble ingredients (which I have made before and was happy with it, and yes the apple essence is fragranced water) and pretend that that is the water phase and then somehow take the silicones and emulsify it all together with the “water phase” that I might get the extremely light hydrating moisturizer that I so like. But this might be because I have minimal experience and need to educate myself. I am sorry to even bother you - reading trough the discussions I realize now that this is a professional forum and assumes one knows the basics. I do have science background but I am not a chemist.
If I post the question like this : How do you combine Hyaluronic Acid powder and slilicone base ? Can you then please give me some advice ? Thank you so much ! -
Thank you and sorry I should have said that at the beginning. I am trying to make a facial moisturizer with very light texture, with no oils, that absorbs well and has superb moisturizing properties ( hence the HA) . It is just for myself - I have tried some like that that are commercially available but the price is what I do not like. So in essence I am trying to make a small batch of a similar gel moisturizer myself. I am really not experienced and have just a very superficial knowledge but I am very keen to learn and any advice would be appreciated.
Thanks again -
I googled some more and came across Decyl Glucoside - woul dthat maybe work ? If so how much and when could I try to add ?
Thank you for any advice.
