Perhaps at that percentage of acids, they hadn’t had any complains regarding irritation. Normally an anti-irritation ingredient is added to reduce the irritation or perhaps the redness, to provide some soothing to the skin. For my own acids even if it’s a low percentage version, i’d normally add one.

MemberNovember 3, 2020 at 2:59 pm in reply to: Basic advice needed about my recipe + adding ingredients during “the cool down phase,” please . . .You can check the formulation guidelines, personally I prefer to add vitamin c types during the cool down. Some derivatives can withstand short periods of heating but there’s not much point in heating them really.
-
I believe they actually used the suggested co-emulsifier stated on the PDF. I couldn’t find it. So didn’t continue with it further at that time.
-
Unfortunately I’ve not looked too much into the co-emsulsifiers yet to give you an accurate answer.
-
Sodium chloride or other salts should stabilize it if you intend not to use a co-emulsifier. They should have the salts included in some of the sample formulas.
-
It looks fine. I think you will still need to use the salt as a stabilizer or a co-emulsifier. It won’t be stable by itself unfortunately.
-
What ingredients do you intend to use with it? Or perhaps you can look into duping the cicaplast. I’ve been intending to do that but it’s not my priority at the moment.
-
Yup, no xanthan. I tested with Sepinov EMT 10 & Sepimax Zen. You should be able to thicken with the oil based thickeners normally, so just that the water based ones won’t be compatible. You can refer to products like the LRP Cicaplast Baume B5, or to the sample formulations in the PDFs. Remember to download in case i move it.

MemberNovember 3, 2020 at 6:39 am in reply to: Basic advice needed about my recipe + adding ingredients during “the cool down phase,” please . . .Reconfigured as below:
Phase A
7% almond oil
7% olive oil unsaponifiables
3% cetyl alcohol
1% sorbitan stearatePhase B
64.5% water
5% glycerin
0.3% xanthan gum
3% niacinamide
0.2% sodium phytatePhase C
1% green tea extract
4% tetrahexyldecyl ascorbate
3% acetyl glucosamine
1% Euxyl K903Would recommend using a green tea liquid extract instead of the powder. If you prefer the powder, you might want to make it into a liquid and ensure that it’s not grainy. Yes, slurry the glycerin & xanthan.
If you are concerned about the almond oil, perhaps don’t heat & hold. If you prefer to heat & hold, perhaps you can add it before emulsification.

I have saved some of the PDFs and linked via my dropbox as below. You can download it for reference:

Generally it’s an W/O emulsifier, somehow i find that the skin feel is slightly draggy. You won’t be able to use a water based thickener with it.
-
The Korean formulators like to do it this way but it’s mainly the Astragalus that is the water since it’s likely a Astragalus water but they had called / registered it as an extract.
Perhaps in terms of “essence” wise, it’s normally a water product that has a high percentage of an extract or filtrate, though normally filtrate like ferments. An “essence” can be used in the toner / essence step in the Korean multi step routine.
-
If my guess of your “PEG 6 CAPRYLIC CAPRIC TRIGLICERID” is the same as what i think it is, then based on my experience, it dried my skin slightly. I’ve not tried the others you have mentioned.

MemberOctober 22, 2020 at 12:42 am in reply to: Looking to enhance the mold protection of Euxyl PE 9010 at 6.0 pH.From the results on ulprospector there are some blends, but i didn’t manage to find any when googling, so i’ll probably buy the Phenethyl alcohol separately.
I’ve tested with the Phenylpropanol (and) Ethylhexylglycerin from Making Cosmetics, the fragance wise i’m fine with it but if when using plant oils, you won’t be able to smell it anymore. Not sure if Phenethyl alcohol will be the overwhelmed by plant oils. Also Phenylpropanol make my skin tingle, not sure if Phenethyl alcohol would. I’m hoping not. If not i would have to stick to PE 9010 and perhaps use a booster.

MemberOctober 21, 2020 at 8:35 am in reply to: Looking to enhance the mold protection of Euxyl PE 9010 at 6.0 pH.How about Phenylpropanol or Phenetyl Alcohol? Though both has a rose fragrance to it. I believe Phenylpropanol is lighter in terms of fragrance based on the comments here:

I’d say it depends on the type of ingredient you are intending to aid the penetration. You might be able to find a test online. For example, for Ethyl Ascorbic Acid, Glycerin is only second to Propylene Glycol. It depends if you want to have the additional benefits of glycols or diols in your formulation as well.

I believe they are edible, if they are food grade. Not sure what you are comparing?

I don’t think i’ve seen you mentioned about the split sales though, haha.

MemberOctober 16, 2020 at 12:16 am in reply to: Help me interpret my cream results from a consumer perspective.It depends on the demographic you are marketing to.
If you are marketing to the Koreans, they are fine with the slightly glossy or so called “dewy” look that is normally achieved with makeup.
For the rest, they might be more concerned about the “absorption”, as the look of the product on the skin might be part of the aspect of said “absorption”. Some people might also regard the “dewy” look as greasy.
I’d say the only way is to ask the demographic, for example via reddit for their preference in the “finish” of the product.

Have you tried 3:2 for 202:68 + 0.6% to 0.8% Aristoflex?
Just thinking how it should go at at the moment. It’s the combo i’d try.

MemberOctober 8, 2020 at 12:53 am in reply to: Critique my niacinamide moisturizer? BTMS, Floraesters, Cholesterol..You will need to confirm the xanthan is compatible with the BTMS, though i’m not sure about the DuraQuench if it will be, if not you can try replacing it with a non-ionic liquid crystal emulsifier.
What is the require or restriction for acneic skin anyway? Just curious.

MemberOctober 8, 2020 at 12:41 am in reply to: Floraesters K-20W - experiences? Worth it or just add more glycerin?@Pattsi there are some covered by this pdf here as i found it when searching for info on triglycerol
http://www.scientificspectator.com/documents/personal%20care%20spectator/Glycerol%20a%20Moisturizer.pdfFor the PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin or Wilbride S-753, it’s more of a premium version of Glycerin with a less tacky skin feel, though it seems to boost the humectancy if in a higher humidity environment. It seems to have some additional interesting properties like inhibiting the absorption of lipid ingredients.
http://www.nof.co.jp/cosmeticlounge/english/material/pdf/wilbride_s-753d_(leaflet).pdfHaven’t tried the others so can’t comment too much on those.
I think a mix of Gylcerin, Wilbride-s753 & Diglycerin would be a good experiment.

Hope there will be a Diglycerin thread, perhaps you guys can order, repack and sell it

MemberOctober 6, 2020 at 9:08 am in reply to: Floraesters K-20W - experiences? Worth it or just add more glycerin?Thanks for the confirmation @helenhelen. I’ve ordered 100ml from China since it’s seems there’s only 1 repacker there. They do have triglycerol but based on the one of the paper i read recently, Glycerin has a better healing rate, followed by Diglycerin, though i can’t find much info on Triglycerol itself to determine how well it performs.

MemberOctober 6, 2020 at 12:40 am in reply to: Floraesters K-20W - experiences? Worth it or just add more glycerin?I’ve noted my experience on the other thread already (ISIS vs DuraQuench).
I find K-20W very interesting since i’ve tested at 0.5% in a toner format, 2% to 3.5% in a gel cream format.With my original gel cream formulation, at 1.5% Glycerin, my pillow case would stick to my face due to the tackiness, and i can still feel the Glycerin in the morning.
With the K-20W, at 2% with 1.5% Glycerin, skin feel wise, it seems to alter the tackiness significantly. Touching my face, at about 30 mins after application, it’s as though i had not applied anything, but my formulation is still working as my dry patch went away as i tested it for at least 5 days. When i used 3% K-20W with 3% Glycerin, the skin feel is the same. I’ll probably try loading it with 5% Glycerin next.
My skin is prone to breaking out but so far it’s significantly effective for my dry skin, no breakouts so far.
In terms of sheen, here’s the photo i took. I had applied a gel cream with 3% K-20W on the right side half, as you can see there’s no sheen. There’s a blurred reflection of the ceiling lights on the table, so you will be able to judge for reference.
I’ve not yet tried 5% Glycerin with it yet, so perhaps i’ll try it with @Graillotion 2% recommendation soon. Though i’d like to also test out different combinations with the Diglycerin that @helenhelen mentioned. I think there are a few humectants that i can purchase, i would like to test out further.
The diagram is from the NOF Macbiobride series, quite a few manufacturers has this 4 ingredients, so i’m supposing the Diglycerin would perform similarly to MP-10P based on description. I can’t find the MP-10P, so i’ll have to try the Diglycerin to find out.
