@simona Standard technique is to use your Citric acid as a 50% Solution (usually pre-made in the lab) regardless so that offsets some of the advantage of Lactic acid. Citric acid is freely soluble.

@KrystleA Where are you located?

Ben, Great post! My opinion on Natural preservatives is right in line with yours.
Robert Zonis was posting regarding Leucidal before the site crashed. Through him and several other sources I heard rumblings regarding issues with Leucidal in the last quarter of 2013. Primarily the issues were with Yeast/mold coverage so Potassium sorbate is the way to address that.
Grapeseed Extract is an over hyped “preservative.” I will not open that can of worms, but I would not recommend it to anyone.

Welcome Back Ben! By the way I have sent some clients your way (can’t say which due to NDA) and each one has had a positive experience.

They stay under the radar I believe. Perry has some experience with patents so he may be able to better respond.

I believe that the use of Vitamin C with Ferrulic acid is protected under patent.
I have had good luck with an anhydrous formulation based upon silicones. The ascorbic acid is soluble in PEG-8. The background for the Formulation is outlined in a C&T Article from 2006.

Same here. I have a Chemists Corner post on my to-do over the Holidays.

I would have to look at the formula. It could be pretty straight-forward. Of course, you would need to ensure that any additions do not destabilize the Formulation. Stability testing would be highly recommended.

I was always under the impression that the proper INCI is “Cetearyl Alcohol.” in VVF’s sell sheets for the Vegarol line they use “Cetearyl alcohol” but go on to state that it is also known as Cetostearyl alcohol.
In the Vegarol 1618 line they supply it in 30:70, 50:50 and 60:40 blends. -
If I were looking for a Formulator in the UK I would check with @Duncan (he has re-registered). He has worked in the Industry in the UK for an extended period. Lacking that I would contact the International Society of Cosmetic Chemists for a referral.
