Fatty alcohols in hair conditioner
Hello everyone,
I’m still very confused concerning the % of fatty alcohols in my conditioner. i had to use 7% (mix of cetyl and stearyl alcohols) to be able to reach a good emulsion. However, i saw that its recommended to stay <5%. Even though im using also tylose in my water phase. Do you think i can use 7% or i should stick to less? if thats the case what can i add along with the cetyl and stearyl alcohols?
Thank you -

People use less because they like to use less. If you like to use 7% then there is no problem in that.

@Anna_Maria If you need to add 7% of fatty alcohols to thicken your emulsion, maybe there’s something you need to fix in your formula or manufacturing method (both affect greatly the final viscosity).

I’m Preparing a water and oil phase (heated to 70 degrees) then added together, homogenizer and cool down. Silicones are added to the cooling phase.

@Anna_Maria You need to be more specific. Do you add the oil phase slowly? Are you using a turbine mixer or an homogenizer? At which speed and for how long? Are you able to hold the temperature (70°C) during the whole emulsification process? Do you switch mixers and speeds during cooling down? Do you cool down with room temperature water or cold water? All of those things adfect your final viscosity.
Now, besides the manufacturing, do you use a structural (polymeric) agent to thicken your water phase?

i’m using tylose to thicken water phase

@ketchito for the mixing im using a mxer and add oil slowly, keep the mix at 70 degrees for 10 mins high speed then cool down at room temperature at low speed. After cooling i homogenize for 5 mins then add cooling phase

You forgot to write your formula

@Anna_Maria You usually use a homogenizer (if available) during the emulsion process (higher shear rate, lower particle size, better stability, higher viscosity, compared to a mixer).
