MemberApril 4, 2018 at 7:05 pm in reply to: Clay mask question please: does this formula require a preservative (no water, yes oils & honey)@Doreen I think with PE based Phenonip if you have a water phase I would split and add half to water and half oil mainly due to solubility of parabens.I think adding it to the oil phase in this case should be hot and shouldn’t affect emulsion stability.

MemberMarch 26, 2018 at 9:31 pm in reply to: Shampoo too thin… can I thicken after it’s done?Too expensive as high ratios or CAPB/Anionics are required usually between two-three to one.Salt is hard to beat.

MemberMarch 26, 2018 at 8:56 pm in reply to: Shampoo too thin… can I thicken after it’s done?The salt should work fine with or w/o Coconut DEA so just do a salt curve.You may have to increase salt slightly after removal for next batch.

MemberMarch 26, 2018 at 8:41 pm in reply to: Shampoo too thin… can I thicken after it’s done?Salt as sodium chloride is table salt which will not interfere with your dry/damaged color Variant but you should get ingredients as you will need them for label.

Let’s invent one in this thread 🙂@Zink Alkyd resin technology is the right model, unfortunately as per above, they are used in paint/varnish industry Now translate that model to a cosmetic bio-adhesive which will adhere for 24 hours.You can test bioadhesion as a function of time in the lab: we did it fr the stomach/gastrointestinal mucosa and helped develop a nice product currently marketed by a major player.

@JessicaMoon With all due respects,I think this is beyond your current expertise and resources.Having been involved in similar projects from synthesis through methods development analytical methods.ACS and INCI name depending on process. scale-up in manufacture, product development, you are biting off more than you can chew.Buy the herbal extracts for Infusion and save yourself considerable time and effort.

MemberMarch 4, 2018 at 7:23 pm in reply to: How’s my Retinol night time moisturizer? Formula critique please 🙂Some reasons are more important than others such as Peroxidation of squalene in sebum which is likely present on skin in the ppm range: not all potential comedogenic substances are concentration dependent.

Formula critique please 🙂Rabbit ear test is not very reliable except for screening http://journal.scconline.org/abstracts/cc2017/cc068n04/p00253-p00256.html I am aware of paper you posted above but don’t believe it(squalene in sebum is comedogenic at low levels as is oleic and linoleic +linolenic acids)) and if what you say is true, than why are you getting comodones with retinol?
