Thank you David.    

Are there any significant conditioning (skin and hair) property differences between Cetyl Alcohol and Stearyl Alcohol?

This would help me to decide which one of the 3 fatly acids to use and at what ratio?

Thank you,

Vida

Dear Perry.

I wonder why some formulas include all 3 fatty alcohols: Cetyl Alcohol, Stearyl Alcohol, and Cetearyl Alcohol together?   If Cetearyl Alcohol is a combination of both Cetyl and Stearyl Alcohols, why not just using Cetearyl Alcohol by itself (higher amount)?  The Giovanni conditioner ingredient list that I sent to you in my Hair Conditioner Formula question is a good example of that.

Thank you,

Vida

Thank you everyone for very informative comments.  

In your experience, which brand of the Guar Hydroxypropyltrimomium Chloride is best (Ecosmooth 100 by Dow Chemical, Jaguar Optima by Nexeo Solutions/Solvay, or others)?  

Thank you,

Thank you very much Perry.  This really helps.  

I know it is hard to guess the amount of glycerin that they are using by just looking at their ingredient list.  But do you think high amount of glycerin (higher that 3%) could also be a contributor?

Thank you in advance.

Hello Perry,
I spoke to Thor Company and  a few others, they all indicated that the starting material for Behentrimonium Chloride is petroleum.   Do you know of any suppliers that might have the plant-based version?

Thank you,

Dear Perry,

For the last 6 months, I have been working on formulating natural shampoos and conditioners that contain no sulfate and petroleum.  I have learned that almost all shampoos and conditioners sold at Whole Foods Market contain some kind of petroleum based ingredients such as Behentrimonium Chloride, Stearamidopropyl Dimethylamine, etc.  Would you consider these types of products as Tier 3, 4, or not even in the natural category at all?  

I want to get your opinion on Sodium Methyl Cocoyl Taurate and Rice Quat.  Would they be qualified to be used in the Tier 3 Natural products?    Are there any concerns about these two ingredients in the natural market?

Hello Perry,

My name is Vida.  I am one of your students in the Natural Formulating Course.  This is my second course with you. 

I have been studying and experimenting with natural skin formulation for the last four years.   During this time, I have become aware of its challenges to compete with the non-natural products.  I am very excited to learn more from this class and to reconnect with a group of cosmetic formulators and experts.
