  • I think they just paint different parts of the picture and we need to take all of them into account. However, as Perry mentioned, if someone doesn't have an issue with SLS, why bother looking elsewhere? If the surfactant is "too effective" wouldn't …
  • And this is directly from the manufacturer:
  • Well, there are some studies available too that link SLS with more irritation. I thought it was you who mentioned on Beauty Brains that SLS has a smaller molecule size and might more readily penetrate and therefore stay deposed in hair follicles, no…
  • OrganicPap said: Thank you for getting back to me! Yes I am selling it everywhere and the product sits in Amazon warehouse? Once the product hardens/freezes I can get it to liquid form again. I tried running it under hot water. What else do you s…
  • It is their face oil, where marketing page says: KEY INGREDIENTS Formulated with a blend of six ultra rich, luxurious oils: Evening Primrose Oil, Jojoba Oil, Macadamia Nut Oil, Argan Oil, Safflower Oil and Japanese Yuzu Oil for a delicate fragran…
  • Are you selling to the Northern states? If packages are left in front of the door, they most likely freeze. You can do a freeze/thaw test to see how the oil behaves in these conditions.
  • I was under the impression that fatty acids do matter for the healthy sebum composition. Luxury brands just add palmitic acid and linoleic acid directly in their creams, omitting vegetable oils as their source. I am not there yet to be able to purch…
  • Thank you! I haven't seen any claims regarding volatility, just the spreadability and film-forming properties. I agree stability against oxidation is a huge benefit too. However, these are my issues from a formulator's perspective. In order to justi…
  • @ngarayeva001 if you read in Russian here is more information: http://vitazone.ru/forum/showthread.php?t=2413 Based on what I have read so far in order for surfactant to form stable micelles in o/w emulsions it needs at least 15% of oil phase conte…
  • @Doreen they explained the mechanism of polyunsaturated oils oxidization pretty accurately. The article is long, I didn’t evaluate every statement in it. I was hoping it provided enough context for dtdang to continue his exploration on the subject o…
  • ngarayeva001 said: Well, not science just my experience: grape seed oil and rosehip oil both mostly polyunsaturated with high iodine value. Both go rancid in months and reduce stability of the emulsion. Not personal experience but an observatio…
  • @Dtdang I didn’t validate the quality of the article, tbh. Just searched for a quick reference to give you more details. I did learn about oxodization of polyunsaturated oils from cosmetic chemists working with at large manufacturers and then strugg…
  • @Dtdang here is a detailed article for instance: https://www.alifeadjacent.com/skin-aging-causes/
  • Thanks everyone! I am just amused companies like this aren't reported to FDA, let alone sell thousands of products on Amazon. I wonder if their "Made in USA" statement is also a lie...
  • @Belassi do you refer to the non proper INCI naming of the ingredients or overall unrealistic percentages and combination of ingredients?
  • I am questioning sunflower oil. You really don't want to use polyunsaturated oils in a lotion for a day wear that might oxidize and damage lipids in the skin.
  • I noticed that some ingredients on makingcosmetics are marked as made in china. Does anyone know if MC is doing their own quality assessment prior to re-packaging or is the customer on its own if the product is not pure enough?
  • Pubmed is usually a great resource. Here is an example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2921764/
