  • I used to make several formulation with Sodium Cocoyl Isethionate as anionic surfactant, I didn't get it sticky in any of them.  They may have other ingredients in the formula which may cause stickiness.  https://www.ulprospector.com/documents/11758…
  • Hello I'm a Cosmetic Chemist for more than fifteen years.  Currently, I'm available for new opportunities.  My e-mail:  OMELNOOR1@YAHOO.COM
  • For the sticky feeling, you may try adding Dicaprylyl Ether (1.5 - 2.5%) and Glyceryl Oleate (0.1 - 0.5%) after adding Plantacare 2000 up.  I didn't notice Anionic Surfactant in your formula ingredients.  You have Plantacare 2000 up (Non Ionic Surfa…
  • As a Thickener, you may add Carageenan (Viscarin) in 1.5 - 2.5 % (in the water phase) or Cellulose gum in 0.5 - 1% (in the water phase) or Magnesium Aluminum Silicate (Veegum D) in 1-1.5% (in the water phase)
  • If you feel it's excessively foaming, it may be because of the high % of surfactants and the low % of water.  Some Manufacturers used to do that if they are using significantly Low Active surfactants.  For example using a certain brand of Sodium Lau…
  • If you, still, feel drying, there are several moisturizing agents in the Raw Material Market.  If you prefer Natural Moisturizer, you may use sodium PCA, Hyaluronic Acid, or Squalene.  This is if you like to stay away from the moisturizing Oil Blend…
  • To make it watery and liquidy, you may need to raise up the Water % up to 90% - 95%.  In this way, you can compensate the extra water you add in the formula. You may replace Beeswax by Cetearyl Alcohol which acts as emollient and thickener.  You may…
  • If you can provide the INCI Names with the full names of your ingredients, that could be helpful.  If you mean Carbopol by CapB, I observed, in your formula, that you are using 12% CapB.  I used to make shampoo and shower gels using 0.25 - 0.3% Carb…
  • I tried cetyl alcohol and cetearyl alcohol together in one formula, I never got any problem.  The formula stayed smooth and homogenous for 3 years.  Not grainy.  No separation either.  In that formula, I didn't add any thickener (no Carbopol, no xan…
  • I passed by a formula ending with pH 5.0 - 5.5 (still in the Rec.Range).  I like the ingredients but it, still, has 10% alcohol.  I don't think it hurts if it comes with more than 75% water or it could be decreased to 5% may be. https://www.ulprosp…

  • Regarding my post on March 19, for OTC which includes API, they should be Pharmaceuticals, therefore, I refer to the FDA Stability Studies for Pharmaceuticals: https://www.fda.gov/downloads/drugs/guidances/ucm073369.pdf But, it's non - binding rec…
  • If you want to use SCI with Chembetaine, try to avoid using them in the same %, you may use them in the ratio (not the %): SCI:CHEMBETAINE  1:5 which means you may use 4% SCI to 20% Chembetaine. https://www.ulprospector.com/documents/1175870.pdf?bs…
  • This is one of the formulas I passed by which contains even Stearate (not directly stearic acid).  The formulator in this formula has to heat the Stearate (Oil Phase) up to 80C   https://www.ulprospector.com/documents/1138916.pdf?bs=1254&b=2034…
  • Yes, I noticed the rebound effect of cetearyl alcohol
  • You can use the homogenizer, if the emulsion is still thin at room temp (at the end of the emulsification).  If you can leave it overnight, it may thicken up over night based on the concentration of the the emulsifying agents (including Stearic Acid…
  • Sorry, you may use 20 min, for mixing on High Shear (Not Homogenization) with water phase, etc..till the end of the post (Re: JOJO91343 AT 10:38pm)
  • For Stearic Acid, you may use 20 min. for homogenization with the water phase, as long as the temp dose not drop.  When you can cool the emulsion, it should be very fast (preferably bu ice) in the lab.  You may switch to medium - low homgenization w…
  • I think the combination tanelise used in March 22 is fine.  If you like to use Stearic Acid, you need to have really good heating system and when you add the oil phase (with stearic acid) to the water phase you need to keep the temp. in the same emu…
  • The most frequently used Natural Preservatives I passed by are the three you already mentioned, in addition to Sodium Benzoate, Ethylhexylglycerin, Zemea Propanediol, Ethyl Lauroyl Arginate, and some others.  If you are formulating for EU Standards,…
  • For Stability Studies, the min. submission for the Long Term should be 1 year and for retesting, it can extend up to 3 years.  Also, for refrigeration and freezer, it can extend up to 1 year.  If you can make the freezing down to -25C, it can be bet…
  • You can still do both techniques whether to neutralize before adding anything or to neutralize after adding the surfactants.  I did both techniques in the same formula and I didn't have any problem.  For shampoo, I, always, do high shear in the hydr…
  • Doreen.  That's a good question.  It's the nature of my mind. In the year 2013, I didn't know the best way of dissolving Salicylic Acid in water phase and/or oil phase without separation in the long run passing all the Temp. and Humidity Conditions …
  • There are different solubilizers for Salicylic Acid even for only water based formulas. The key factor is whether it will dissolve completely or it will separate after some hours. After dissolving it, you may leave it stagnant for some hours. If it …
  • For Salicylic Acid Separation, try to monitor Stability Results: If the product is OTC or if it has API like Salicylic Acid, you may run Stability Studies .  Usually The Stability Studies are Long Term (3 years in case of OTC - 25C),  Accelerated (3…

  • If you like to try Sodium Cocoyl Isethionate, here is the formula I'm referring to : Page 6 in the link https://www.ulprospector.com/documents/1424771.pdf?bs=581&b=211769&st=1&sl=59477158&crit=a2V5d29yZDpbc29kaXVtIGNvY295bCBpc2V0aGlv…
  • Regarding the Preservatives, you may also try Zemea Propanediol https://www.ulprospector.com/en/na/PersonalCare/Detail/2624/79261/Zemea-Propanediol
  • I like the first technique: "In one formula the Carbopol is added to water and then neutralised before any thing else is added" because the anionic (SLES) and Amphoteric Surfactants (CAPB: Cocamidopropyl Betaine, if my guess is right) are mostly wat…
