  • For what does GL acid stand for? Glycyrrhizic or glycyrrhetic acid? It could be the reason for clumping. What is Tepex? Can't be THIS product unless you're mentioning packaging materials in the LOI because it's sooo super fancy! Out of curiosit…

  • Zinc oxide may form organic zinc salts at low pH (likely, only a small fraction will react) but since a low % of for example zinc sulfate is allowed in cosmetics, it shouldn't be too much of an issue... but then again, who knows without knowing? If…

  • From what I understand, it's basically a high water content cold cream which breaks upon application. Nothing fancy there except for a lighter texture (more water and hydrophobic clay instead of wax) than traditional cold creams... BTW a water phas…

  • Zaf said: ...Water: 2 Tbsp - Purified Water 1 Tbsp - Magnesium Chloride 1 Tbsp - OptiMSM ... First: Please don't use "spoons" as a measure! For example, rough salts have a different weight than finely ground salts. Hence, if you're pos…
  • I kinda zapped that you don't have a standard emulsion but a shampoo... that might change everything. Did you try thickening with salt? Might work.
  • Gura hydroxypropyltrimonium chloride is in theory incompatible with glyceryl stearate citrate. The latter though is composed of mostly glyceryl stearate plus some % (theoretically anionic) glyceryl stearate citrate. Depending on the degree of modifi…
  • It doesn't necessarily have to be below 4 but it might help. Also, you have a stabiliser (acetanilide) and you have a chelator (citric acid). I certainly wouldn't use a stannate in a skincare product though exchanging citric for etidronic acid might…
  • What is the INCI name of your emulsifying wax? There are several different ones . If it's the one containing boric acid, then this might be the source of hydrogen peroxide decomposition. Regarding stability; how do you know that it's not stable? Do…
  • ngarayeva001 said: ...whether anything can be don to fix it. Degas in an ultrasound bath . Just received mine last week! Going to use it to degas water and try to make micro/nanoemulsions (and obviously clean my stuff). Anyway, pigment…
  • Are you saying that you're trying to mix bleach with hydrogen peroxide or that you want to make a skin bleaching solution containing hydrogen peroxide? Depending on the furnisher, hydrogen peroxide is sold with a small addition of stabiliser (usual…
  • For my hair, glucosides (in mixtures) are great and sulfates are bad (I have no problem with sulfates per se)! Just saying, there is no "good" or "bad", there simply is something for you as there is something for me and it's probably not the same be…
  • Do you mean something like THIS?
  • Cst4Ms4Tmps4 said: ... - 1% Trimethylglyine can emulsify 0.5% Salicylic Acid - Not sticky - Can reduce stickiness (of other ingredients) - Superior to all surfactants and emulsifiers - Superior to Glycerol (40% improvement in hydration as oppos…
  • Organic? Define "organic"! If you go by Swiss organic standards then there is no such ting as an organic surfactant, there is not even organic cosmetics because cosmetics aren't good for nature no matter how sustainable they have been produced. Pla…
  • There's more than one Polawax. It also depends on the composition of the oil phase of your emulsion and on the water phase too... The answer is "Yes it can be a good emulsifier" if you choose your o/w emulsion to fit the emulsifier or "No it's unli…

  • I see you did some real deep meditation and have consulted with the ghosts of Einstein, Curie and consortium . Regarding "shielding": What you show is the part about bridging . Maybe try to imagine magnets instead of electrons? Why do you …
  • vjay said: hi anybody can help @chemicalmatt already did. He proposed using a "pigment dispersion aid" (dunno if there is a proper name for this). There's a bunch of such compounds available which also tend to be well suited for sunscree…
  • IMHO most plant extracts (except oils) are purely claim ingredients in rinse out formulations (and probably in the majority of all other cosmetic products too) and I never understood why bamboo should be in a haircare product other than reminding pe…
  • Docaashu said: ... My question here to experts in chemistry is that - "Can any formulation be prepared which is slightly acidic (pH 6-7 at par with pH of skin) with good cleansing property ?" (good for skin and hairs) Yes, it can and it'…
  • It's hygroscopic, it might even clump if customers don't use the whole mask at once. You have to seal it hermetically. These biotech-peptides are usually used at much lower concentrations (probably they're just pixie dust).
  • You could but it would make bubbles because of the reaction of bicarbonate with acid. For cleaning, sodium carbonate is usually employed since it's high pH (unlike pH neutral bicarbonate). This helps removing fats and oils. If that is not needed, t…
  • Isn't there a thread already about that topic? IIRC bottom line was that it's a marketing term aka misnomer.
  • @ngarayeva001 If it stinks real bad, then it was likely thioglycolate.

  • I would say that parabens at a pH of 13 will definitely hydrolyse (= degrade). Also, vitamin E as tocopheryl acetate will hydrolyse forming tocopherol; that one becomes highly sensitive to oxygen at a pH of 13 and will work too good for too short. …
  • @crillz It's actually THAT one. Was cheaper with better customer rating... Ran it against fresh calibration solution, pH strips (the ones with a bunch of small colour squares), and a temp meter. Values seemed correct. EC I still have to check. For…
  • If there is a perfect drug/medicinal plant, then it would be curcumin/turmeric. It literally does everything beneficial and nothing harmful, no matter which in vitro test you run and we are talking thousands of different tests and hundreds of public…
  • @Doreen Okay then! BTW hibiscus extract is usually acidic . Salicylic acid is a weird thing because of the phenolic group just a carbon atom further away than the acid. This stabilises the acid; hence increased oil solubility and reduced interacti…
  • Smart people EAT it . In cosmetics, biotin does nothing but boost the label. Since it is water soluble, using it in powdered form does fine.
