Agreed with @Belassi and @MakingSkincare but generally downsides overshadow the upsides. Anyhow my personal favorite is Sepigel 305 and its magical if used properly in a formula, hot or cold doesn’t matter.

Another thing that I would like to ask you if I can still refer the first edition (1991) of it or it can be called partially obsolete now???? -

How can I buy the latest Harry’s Cosmeticology, is it available online??? -
Try Sepigel 305 or Dow Corning RM 2051 or Rapithix A60 although my personal choice would be Sepigel 305 because of the feel and the body/structure it provides to the formula.
Just hoping that you don’t have any cationics. -
Water, Alcohol Denat, Passiflora Edulis Fruit Extract, Citrus Medica Limonum (Lemon) Fruit Extract
@braveheart This is the INCI supplied by the supplier and I would think of it as one ingredient after deciding it’s place in my formula depending on the dosage. Anything repetitive in the INCI listing would be clubbed with those being in the main formula e.g. water being clubbed with water of the main formula or if ethanol is there I would club ethanol together. Below 1% you can put it anywhere you want as we all know.As for the query by crisbaysuli I think the supplier must have given the INCI name and and it can be mentioned as per the ratio of the product. Though if you see we have cetostearyl alcohol where generally it is 30 cetyl and 70 stearyl alcohol. But we dont mention it like that, we just use the term cetostearyl alcohol. -

Try 7 parts of partially neutralized carbopol dispersion with 3 parts of your high pH recipe, check how much the pH comes down. Try it on the lab scale and then proceed further.

@ Kirk
Great info, thanx a ton. -
@Kirk How would you recommend the order of addition of these 2 polymers into the water phase, secondly considering the ionic nature do you thick these 2 will sync nicely??

Everything seems fine except that new notification of comments or newly started topic is not being displayed regularly. Visible in some cases and missing in some.

I have had a sample of Synthalen W400 from one of my suppliers and they say it’s great with such formulations. Maybe you can give it a shot and see if it holds up, although I have used Crothix liquid and Rewoderm LI S80 and the results are good.
But my formulations are based on SLES/CAPB and sodium chloride as the main components. -
@Belassi I am making a soap of Olive oil and KOH with some other oils which they call Acid oil, do you think we are on the same page or the product you refer to is Black Beldi Soap different from Moroccan soap that I do.
-
@Belassi Black soap meaning the Moroccan soap which is high in pH (around 12) and is a concoction of oleic acid mainly and alkali.
Guess Andy is based in UK as he talks of pounds and Korea to UK flight@Andy1987 Guess Belassi has made a great point but still if you have this hunch about those 2 ingredients then you search those products where these are used and if you think if any of it closely resembles to what you used then no need to make anything and asking the suppliers for samples. -
The breakdown of your sunscreen agents is the only cause that seems to be into play here. Check the temperature dependent degradation rates of your sunscreens and it would give you a fair idea about this phenomenon.
-
I am sorry but you cant use carbopol with a cationic formulation, either up the fatty alcohol or better use the combination of cetyl and cetostearyl that I do and it thickens great. Or use a cationic thickener like a polyquaternium 10 or 37 or which is available to you easily and fits your cost. With a cationic thickener you can reduce the quantity of your conditioner also as the thickener also provides the conditioning.
-
A normal o/w emulsion with a small amount of a fatty alcohol (cetyl/stearyl/cetostearyl) gives your emulsion the LC properties. But it’s always better to read and research before doing something new and interesting, makes the experimentation all too thrilling and easy to understand.
cheers

Yup the trick is to pump in enough solubilizer where the oil remains completely solubilized in the final formulation just as I do in the case of salicylic acid and prevent it from recrystalization in the formula.
-
The formulation suggested by @Iaskedbetter is a perfect one with those ingredients that you have with you. It should give you a good stable lotion, try it and I think you would be pretty close to where you wanna reach.
