  • A few years ago I was paying a visit to a supplier. While we were talking I saw a pallet of egds, and remembered I had to buy a pearlizer. I asked if he had any, or if they could make a quick batch. The owner told me it was one of the longest to pro…
  • Sure, but it won't work with an anionic carbomer.  Besides, for effectiveness it's recommended to formulate a mix of surfactants. If you check prospector you will find lots of similar formulas, mainly for hand wash and surface cleaners.  It's a go…
  • Sure, but the same applies to pretty much anything. It's Lisa's rock for tigers, if the consumer wants to buy that magic he will. That's the easy consumer, but the thing is marketing is permanently focused on selling bullshit to everyone. They misle…
  • First, there is a key factor that you need to understand. This is a new virus, therefore the information we have is limited. Governments and companies have to study the virus to know more, and that won't happen for at least a year. The big companies…
  • Absolutely, that's against the definition of cosmetic products.  Although, if you search the forum you will find plenty about soaping effect. Short answer, add dimethicone.
  • Yes, they are OK. Let me put it this way, you will absorb more carcinogens by taking a deep breath in any city than the daily use of sulfates for 10 years. So why the demand you ask?. Marketing. And of course, if you have doubts rely on trusted sou…
  • Just wondering, what's "lowest speed"?.  You will get better answers if you share more about your setup and process. Without more information all I can add is to thicken it at the end.
  • Unless you give your customers a tour around the lab I agree with Pharma. Besides you risk having to upgrade lab equip more often. If you competitors do the same you risk having to spend a lot of money just because they got the X265 and you have th…
  • To avoid lawsuits and keep the claim on the label an asterisk with a clarification on the back will do the job. It became quite common after the "alcohol free" issue with deodorants with fatty alcohols years ago. But honestly, how many con…
  • Word on the street is that castro oil is great for beard growth. Comes with restrictions though...
  • You are doing it backwards. Ideally you would hire a CFD company to design a machine to make your top sales product. Then you see if you can adapt the machine to make other products.  Spending money on a machine and then figure out what can you do …
  • Wrong. There are standards for a reason.
  • If you are doing it for yourself and you already run the numbers go ahead. Now, if you are going to sell the service to 3rd parties then i'd say your project is doomed already. A silly example. You are making your batch for yourself and 2 customers …

  • Yup, that's thixotropy. What you describe is commonly used on filling machines to accelerate the process. In this case, to make the user spend more. Cute trick right?. 
  • If I had to make a bet my money would be on a combo of cheap quality materials. Although I suspect the main issue is the CDEA. Surely soy, sunflower, palm or anything but cocoamide. Those damn long chains are only holding together because Urea is wo…
  • No, you shouldn't add more, you should change fragrance/supplier. Depends on the product and storage, but at least 2 years. 
  • Well, for starters you are missing a key detail, what products will you produce and how many units. I take you will make small batches of small things like toners.  If so, that list seems OK, but for example, why do you need a centrifuge?. Will a 50…

  • What a shame there's people who will continue to work like this and practically scam customers. We should have some sort of blacklist.  This explains a little the cold war between freelance formulators and contract manufacturers (at least the serio…
  • Yes, that's normal. Hot water or a more hydrophilic co-surfactant will do the trick.  And no, it won't remain a gel since its not a gel, just the material clumping due to its partial affinity with water.
  • Nice topic. My evidence is observation. Double blind tests and consumers feedback. The most important thing I learned is pH should be balanced, although not just taking in consideration the skin, but how's applied, for how long and how often, and mo…
  • Now that I think about it my mother use to clean her cat's eyes with it. Perhaps it wasn't snake poison after all. Strange that a plant that has been consumed widely across the globe for centuries doesn't have further research, or claims in cosmetic…
  • Also it could be filth, mould, the buggers of a sick employee or a portal to other dimension. The thing is you shouldn't care. You got a bad batch from your supplier and you are holding the proof. Even if it's nothing the customers won't see it that…
  • Transportation is a lottery, but perhaps you could improve the packaging. Adding polystyrene beads or something like that it's the cheapest I can think of.
  • Very. You need to consider the worst case scenario. A truck on the road under the sun can easily heat up to 50°, even more. I'd consider tweaking the formula a bit. Far better now than after losing an account and your reputation.
  • Synergy could be another reason.
  • That budget would make sense if you were to make in-house chromatography, but I doubt that's the approach they have. It sounds nice, I'd love to have a space ship if I had tons of money to throw away, but non uniform bottles?? Come on!. As far as I …
  • Yes, EC Regulation 1223/2009
  • @theoracle there are powder fragrances.
  • So what's the purpose of the mg in the formula?.  If the remove the methoxycinnamate I guess you could also remove the Cetiol. You can replace the mix with dimethicone, but you won't get the same performance by any chance. In fact dimethicone is j…
  • @Bill_Toge that's interesting. And regarding temperature?. In my experience fatty alcohols will decrease viscosity above 35°, even using 1% or less.
