  • In my opinion, there is not a whole lot of difference. They might feel slightly different (which most consumers won't notice) - however, some are clear while others are translucent, which is what most people will notice.
  • Unfortunately there are problems in all research-based industries, and even in academia. One thing that I noticed in your posting was the notice that academia (or at least other areas of industry) is better off than industry was this: "Cosmetic sc…
  • @perry there I think you may be right, even though there is several, there are several indications (from mildly biased sources) that it reduces the visibility wrinkles with less scaling than with retinol, so who knows? - We need more independent stu…
  • @Perry actually Bakuchiol is the name of the compound (Cas: 10309-37-2) Bakuchiol was found in and is commercially purified from Psoralea corylifolia. Bakuchi/Babchi Oil is indeed just the expressed oil from Psoralea corylifolia, which depend…
  • You have too low a concentration of surfactants. "SLS Liquid" is likely at 30% concentration (check your documentation/supplier) which would yield an approximately 3.5% concentration of actual SLS. CAPB is also likely at 30% and therefore in tot…
  • @dtdang You can thank the Esters dicaprylyl carbonate, isopropyl isostearate and the Silica in that formulation for that feeling. The many oils are (hopefully) there at a very low concentration and added only as a scent. as for your question "whic…
  • @Royalbre That is very very cheap, so cheap in fact that I would either: A) Find another one or Get the contract read through by another chemist to check for what is NOT included in that price and a lawyer to make sure it is enforcable.
  • @MarkBroussard They probably do extraction in the triglycerides too. But why would they add any triglycerides anyway I mean that in itself is likely to cause lipid pneumonia.
  • There is no reason for tocopheryl acetate to be included. It should contain Propylene Glycol, Glycerin, Nicotine and possibly flavourings (and flavouring carriers). Some news articles have quotes suggesting the use of VE Acetate being added as a th…
  • Other "Actives" from a natural source activating the TRPV1 Receptor (burning sensation from capsaicin) includes Ginger Extract/oleoresin (Gingerol, Zingerol), Pepper extract (Piperine) & Clove extract (Eugenol - allergen). If you want a heatin…
  • Contamination in an anhydrous formula is unlikely, bacteria and mold won’t grow without water.  Phenoxyethanol could be used if you want a suggestion anyway.
  • @MarkBroussard while I partially agree it is also a question of access to information. Not everyone has a smartphone for instance. Then there is the change in formulations (let’s say removal of an allergen) which means it needs to be a batch specifi…
  • For partculates (including silica and surfactants) I use 3M Aura 9312A+
  • Toxicological report on cocamidopropyl betaine (CAPB): https://www.heraproject.com/files/45-HH-E101023F-D12F-6A30-DEB0770E9BF8E4D0.pdf TLDR; allergic contact dermatitis from CAPB is caused by impurities, not CAPB itself. Irritant contact dermatitis…
  • Colormatching is pretty much a trial an error thing. But it depends on what kind of pigment you're using. as it is a concealer you could go very green and fix it with foundation afterwards. However; Colored pigment - you need a small amount. In…
  • Without knowing what they have in their "preservative" my guess would be glycols and an acid. Waiting for a month could be to  1) Improve the story or 2) allow for some of the water in the melon to be drawn out of the fruit and partially replaced by…
  • The only way to have them sterilized in the bottle with no preservatives is a perfect closure system, clean bottles and gamma radiation. And once opened, well then it's bugfood.
  • @Mallow631 Just make sure there is water in the formulation. It is a feature inherit in more or less all humectants. But at the same time, we do perspire water all the time and is not usually something that you need to consider. It was intended more…
  • @Aziz If you look at Poucher's book again, then you will notice 2 things. * The panthenol subsection is the only one without a reference (I happen to own a copy of the book and yes, every other subsection of the "Functional Ingredients" in 9.4.3 h…
  • ULprospecter will only let you register when you work at a company related to the products and services in their database - are you currently employed within the personal care industry?
  • Well, that is part of it, another thing is the "backfire effect"(https://link.springer.com/article/10.1007/s11109-010-9112-2) which essentially is the tendency to increase belief in your current incorrect understanding when shown facts disagreeing w…
  • For moisturization purposes, we usually go with both TEWL measurements in conjunction with dermal conductance measured over time. Cleansing has usually been a comparative washing with relevant coloured products as the reference.
  • Did the product get any sun-exposure? that could increase evaporation in the packaging.
  • Benzyl alcohol may be added as a preservative, if the premix you found is sold in the EU, then the benzyl alcohol may be on the ingredient list due to the content of bitter almond oil, as there is about 1-2% benzyl alcohol present in bitter almond o…
  • When you have a formulation that allows for absorption of the panthenol, then D panthenol would be better for skincare as this isomer is the one our cells convert to pantothenic acid (Vitamin B5), as the racemic (DL) mixture contains both active and…
  • @saraahsan without a formula written down no one here will be able to tell you better than "maybe".
  • ngarayeva001 said: Guys I read a review in the Advanced Cosmetic Formulators group on Facebook and it sounds like that dynamix isn’t particularly good with high viscosities. Sounds like it’s just an overpriced stick blender I mean, you’…
  • @Pharma I agree that chemical nomenclature is easier to deal with. And of course, there are exceptions (Trilaurin for instance) I was basing my question more on the INCI guidelines and other mixed compounds (completely disregarding "impurities"). …
  • @pharma You're welcome!
  • If you are going to invest in a new blender such as a Bamix for emulsions, there is also another possibility. Dynamic Mixers have a variable version with 3000-13000 RPM and a blender/homogenizer attachment they usually cost around 200€ for th…
