From what i've seen when comparing the SDS, Sepinov & Sepimax seems to have a higher biodegradability percentage. Is there a particular reason why that could be the case compared to the others? * Sepinov - 93 % - Inherent - 28 days * Sepimax - …

(Quote) Have you considered changing to another emulsifier blend that can thicken by itself? At least to me it seems relatively high in total percentage.

Normally people formulating natural / natural derived ingredients don't really come after synthetic polymers, i guess they don't really think about it other than the synthetic status? If there are people coming after the plastics, it would be the …

(Quote) You might want to look again at the tech sheet. It comes as acidic & "coiled", it "uncoils" when wetted in water and with the pH increased above pH 4.5, depending on the specific polymer. https://www.lubrizol.com/-/…

Your percentage of Acrylates/C10-30 Alkyl Acrylate is too low. You might want to state the trade name of this ingredient since there are many types, some are not meant for emulsifying. You will normally need an alkaline buffer if you use Acrylates/…

(Quote) No, it will not. You might want to test whether your solubilizer is able to solubilize all your lipid ingredients first then see how much percentage is required to make it transparent. (Quote) No one will know, so you need pH buffers if yo…

There are courses by Perry listed on the main site page, you can see if the modules fit your needs. https://chemistscorner.com/products/

1, 2 or 3 can depend if you have an emulsifier for the oil phase, and a heated process as well. As Graillotion mentioned, sometimes it doesn't matter. When Sepimax is hydrated and formed the gel, just high shear it to emulsify the oil phase, then …

I'm a minimalist, usually maximizing functionality with the streamlined ingredients. I will evaluate & scrutinize my ingredients closely to see if they can have overlapping functions to reduce the use of others if possible. What Microformulati…

You can look for a liquid emulsifier blend or non-bodying emulsifier blend. For example from Making Cosmetics, the CreamMaker® FLUID. Or Montanov L or 202 for non / low bodying solid blends.

@Paprik normally the shear tolerance is mentioned in the tech sheet for the polymers if they are fine with high shear. At least that is what i saw for Aristoflex AVC, Sepinov & Sepimax.

I don't really have a fav but i normally use Sepinov EMT 10 more often currently. On hand, i have: * Aristoflex AVC - If i need better thickening or stiffer * Aristoflex Silk - Something between AVC & Zen * Sepinov EMT 10 - If i need somethin…

I find that Glyceryl Glucoside works for my skin, besides from the ones listed above. I'm in an air conditioned room most of the day and i break out if my skin is overly dry.

I put my thickeners in an air tight container with a large bag of silica gel (I bought a large container of those).

It depends on what you determine ineffective or efficacy, and also your marketing & budget. In terms of product functionality wise, it depends on how you want to define the "wrinkle", "dry" and "aging" to be. How …

Propanediol should be less sensitizing. You can search for Propanediol on https://www.cir-safety.org/ingredients , look at table 12, page 61 of the PDF for a comparison that they reviewed.

(Quote) Seems you more or less have the ideas in your mind. You can perhaps refer to emulsifying blends' SDS that uses Cetearyl alcohol + Ceteareth-20 to combine your own ratio and then use a carbomer. Ref SDSs for blends that contains Cetearyl …
-
If you are using within recommended rates but it stills becomes "watery", it means that your preservative (blend) is destabilizing your emulsion. Try using another preservative. But as Graillotion mentioned, the other details would also …

If you have to use Tremella, then perhaps source it as the original powder form. Some manufacturers do have them in a lower and higher molecular weight. Not sure if it would be cheaper that way but at least you can save on shipping fees due to weigh…
-
Normally powder polymers don't melt, they just get dispersed. So if it's fully dispersed in your oil phase, you can go ahead with the next step. After cool down, you don't particularly need to blend again, it's perhaps better to use a low shear op…

I think most of the common strategies have been covered including the low HLB. Not much more to add on. Normally if i have to use a higher percentage of emulsifier(s), i'd just use silicones. Dimethicone or volatile, depending on purpose. If not…

I would agree that there's some error somewhere. In the previous packaging, they did print 5% Panthenol as a repair balm, as shown on the Singapore version of their site. For the US site, the emphasis is on the Dimethicone as a skin protectant. Pe…

It's on the Singapore version of their site. Not sure if they have it on their US version. (Image) https://www.laroche-posay.sg/cicaplast/cicaplast-baume-b5-for-adult-and-baby-skin

It would depend on what caused the redness, and what you mean by "healing", because sometimes the solution might be different. The percentage of Panthenol is at 5%, so the first few ingredients would very likely help in reducing redness …
-
You will need to ask the supplier for the estimated percentage of the individual ingredients in the blend. They should be able to provide you if it's not found in the SDS (if available). When you have all the percentages or estimated percentage, j…

I don't make whipped butters, but seems that the problem they have is when they make anhydrous whipped butters? I've also seen them mentioning using SOFTISAN® 378 and it would help with that. Doubt you'd have the same graininess issues in an emulsio…

You can see the one from Croda (Link here, since if i paste it, it will break up.)

You can take a look at the brochure. On the brochure, the results are tested after one week of using Isostearyl Isostearate compared to the same percentage of petrolatum. If that is the case, using both could potentially work in synergy since the me…
