EntrepreneurAugust 9, 2022 at 2:30 am in reply to: Deep conditioner or prewash conditionergrapefruit22 said:Companies usually have a division into conditioners and masks. They have similar ingredients, the masks have a thicker and richer texture and probably a greater amount of conditioning ingredients. Below is a photo of a conditioner and mask from the same company, maybe it will be helpful in some way.
Usually they recommend keeping the conditioner shorter - 1-2 minutes, and the mask 5-7 minutes.
Pre-wash treatment is a rare product, usually it is an oil or a mask with a heavy consistency.Thanks a lot

EntrepreneurAugust 5, 2022 at 12:49 pm in reply to: What surfactants are needed to make sulfate free?You can make good shampoo with Sodium Lauroyl Methyl Isethionate + CAPB+ EDTA.
You don’t need anything else. -
SLES is ok in hard and soft water.

I don’t know how much correct it is but someone told me that i should have at least 0.1%, ideally 0.15% organic acid in it’s acid form + a preservative like phenoxyethanol for bacteria + EDTA.
That would be at least 0.7% sodium benzoate at pH 5 to get 0.1% in acid form.
At pH 4.7, 0.5% which is upper limit for leave on product would give you 0.1% in acid form.This is not for cleansing products.
I am looking to hear from experts here about this. -
For skin products i like anionic surfactant alone or small amount of amphoteric maybe for viscosity.
For hair it is different.

A lot of types.
They have different functions so depending to your need one may be better than another.
All are friendly for skin except Amodimethicone.For skin product start with dimethicone.

Reducing the pH to 4.7 helps a lot if you are not using good preservatives.

All of them dissolve perfume.
I would use non of them in body product because they make skin dry.
Lauryl increase viscosity, others reduce viscosity.

EntrepreneurAugust 3, 2022 at 12:31 pm in reply to: Light sensitivity of formalin & DMDM hydantoin in shampoo with transparent package@Perry that’s good. Have you tested shampoos with formalin too?
Was there any side effect from transparent package & no UV absorber in shampoo with formalin?I am using formalin and that may be more sensitive in everything than DMDM hydantoin i think.

@ketchito my shampoos has SLES/CAPB at 3:1 and 7:1 ratios. So it may have coacervate. I use 5% nacl
By desorption, do you mean removing polymer that is already attached to hair from previous shampoo with cationic guar?
Also how does NACL effect PQ10 in shampoo with SLES/CAPB in above ratios?
-
You can adjust pH anytime but before adding surfactant, how do you know how much sodium hydroxide do you need to adjust ph?
Also don’t forget to add chelating agent.

EntrepreneurJuly 31, 2022 at 8:56 am in reply to: Dupe of Clarins Instant Smooth Perfecting TouchYou can heat the product to evaporate the water and see what percentage is total solids.
If it is leave on hair product in my opinion everything is below 1% or Cyclopentasiloxane is 1-2% and the rest of it is below 1%.
