Thanks for the mention, Perry. It’s never a one size fits all proposition, but I’m glad many have found a home for D9.

Thanks John for you helpful reply.

The reason SLS prices are rising is the increasing price of coconut oil. Plantations took a big hit a couple years back due to tropical storms and the effect of that, combined with big increase in use in food products, is driving prices way up.
Sodium cocoate is also a poor replacement from an irritation standpoint. You can’t formulate at physiological pH because it’s mostly free fatty acid at that point. Clear systems require at minimum a pH 8-9, which is quite harsh to skin and especially eyes.

Putting your product in a centrifuge for several minutes, while not typically part of a formal stability protocol, is a good way to get a quick gut-check on how the emulsion will hold up in formal stability.

I agree with johnb. PEG stearates do not make good pearling agents, but glycol stearate and glycol distearate (correct INCI) do. Basic pearling agents like the one described are plentiful.

Colonial distributes through Vantage in Mexico. No need to import yourself.

Neither the Canola Oil nor the Finsolv are water soluble. If you drop phase J, you can also drop phase F. The formulation should build acceptable viscosity without the gum. The amide level seems quite high to me, so I’d suggest playing around with it.

The vegetable oil is, in fact, for marketing purposes. Thanks for the tips, manstra. Unfortunately, the Innospec formulation uses guar gum, which I need to avoid.
