Dispersion of dimethicone in hair conditioner


My name is Lauren and I’m new to this forum. I am based in Utah. My degree is in microbiology but my career was mostly molecular biology (PCR, cell culture, etc.). After a long hiatus, I am in the position of formulator at a personal care company. I have been working 2 days a week for about 4 years. Up until recently, I have had clear instructions from batch records with easy to follow formulations just to tweak viscosity, flavors, scents, etc. About a year ago, I began trying to backwards engineer things like body wash, shampoo and conditioner. I am also trying to come up with my own formulations. The question I have is about hair conditioner and if I can add dimethicone directly to the formulation after adding the emulsifiers or if I have to solubilize it first. I have googled it but have not been able to decipher all of the information. It incorporates well, but I want to make sure it is safe for use. 

Here is a list of my components:

DI water (q.s.)

Glycerin 2%

Panthenol 0.5%

Centrimonium chloride 1.5%

Behentrimonium Choride 2.5%

Cetyl alcohol 3%

Cetearyl alcohol 1.5%

Argan oil 1%

Dimethicone 2%

Essential oil (q.s.)

Methylchloroisothiazolinone (and) Methylisothiazolinone 1%

Thank to anyone for advice/help you can offer on this subject. 



  • Dimethicone will be suspended/dispersed in your emulsion. It doesn't need to be 'solubilized'. You can add it after adding the emulsifiers. Then (properly) mix the whole formualtion (the best option is using a stirrer with 700-1500 rpm). For small-scale-lab-batches (around 200 grams) you can mix for around 5 minutes after adding it. 
  • Thank you!!
