I have some modest experience with O/W products and have an idea how o/w polymers such as Sepinov EMT 10 or Aristoflex AVC work.
Recently I started exploring W/Si world and had to forget all rules I learnt before. For example O/W polymers don’t really like electrolytes (with some exceptions), while in W/O they are must have for stability. I also heard on the institute of personal care science channel that O/W polymers (I think they particularly mentioned xanthan) should not be used in W/O systems because they somehow break the emulsion.
On the other hand there is Seppic’s Geltrap (that is utterly unstable) that mixes Easynov with Sepiplus 400. Seppic however doesn’t recommend adding electrolytes for an obvious reason (they will break gelled water phase). I tried to apply geltrap’s logic to other materials. I mixed Aristoflex AVC with PEG-30 Dipolyhydroxystearate W/O HIPE emulsifier and all I got is a greasy mess with W/O properties that separated the next day. I thought it must be a good idea because Easynov is a combination of PEG-30 Dipolyhydroxystearate and Fluidanov. Apparently it doesn’t work.
Apologies for the long introduction, but how can this be explained:
Water, Cyclopentasiloxane, Ethylhexyl Methoxycinnamate, Cyclohexasiloxane, Glycerin, Isododecane, Butylene Glycol, SD Alcohol 40 (Alcohol Denat.), Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone, Polyglyceryl-4 Isostearate, Cetyl PEG/PPG-10/1 Dimethicone, Hexyl Laurate, Disteardimonium Hectorite, Nylon-12, Glycoproteins, Panax Ginseng Root Extract, Equisetum Arvense (Horsetail) Extract, Glycine Soja (Soybean) Oil Unsaponifiables, Ilomastat, Ursolic Acid, Hydrogenated Lecithin, Retinyl Palmitate, Hydrolyzed Soy Protein, Ascorbyl Palmitate, Plankton Extract, Camellia Sinensis Leaf Extract, Carnosine, Sodium Hyaluronate, Olea Europaea (Olive) Oil Unsaponifiables, Dimethicone/PEG-10/15 Crosspolymer, Triticum Vulgare (Wheat) Germ Oil Unsaponifiables, Algin, Hydrolyzed Malt Extract, Polymethyl Methacrylate, Phospholipids, Tocopheryl Acetate, Caprylic/Capric Triglyceride, Octyldodecanol, Pollen Extract, Disodium Stearoyl Glutamate, Acacia Senegal Gum, Magnesium Sulfate, Squalane, Dipropylene Glycol, Trihydroxystearin, Serine, Acrylates Copolymer, Aluminum Starch Octenylsuccinate, PEG-8, Diphenyl Dimethicone, Polysorbate 60, Cellulose Gum, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Sodium Phosphate, Sucrose, Dimethicone/Vinyl Dimethicone Crosspolymer, Xanthan Gum, Caprylyl Glycol, Aluminum Hydroxide, Propylene Glycol, BHT, Sodium Laureth Sulfate, Fragrance, Butylphenyl Methylpropional, Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde, Hydroxycitronellal, Linalool, Citronellol, Alpha-Isomethyl Ionone, Geraniol, Methylisothiazolinone, Phenoxyethanol, Methylparaben, Ethylparaben, Propylparaben, Butylparaben, Titanium Dioxide, Iron Oxides, Iron Oxides, Iron Oxides
I can see several W/Si emulsifiers on the top of the list mixed with what must be Seppic’s Simulgel NS.
Does anyone know what is the purpose of O/W gelmaker in a W/Si system?
Thanks in advance!
