@pepe cuticule layer is like fish scales when u have healthy hair these scales are closed , but when ur hair is damaged and dry these scales are opened and every material could peneterat to inner layer(cortex). so I dont think so peneterating depends on ur kind of material….

sorry for my delay..yes they are guar gum and polyquaternium 10 and again yes its cationic guar gum. irina why u are searching about the stability of my mask? Im sure that my mask is a stable emulsion because it passes 3 different stability tests.
u know what is my problem? I just want to know when my mask after freeze-thraw cycle get bad smelling so can I be sure that this franrance isnt suitable for my mask? or maybe freeze-thraw cycle is not for fragrance stability?
in other term is there any reliable test method to determine the stability of the fragrance? these are my questions…these are different stability test but most are them are about emulsion stability not fragrance stability.
thanks…

“Did you do a stability test of the unscented product?” really no I didnt.
“Also did you gather information from your supplier if your fragrance is compatible with your end product (a hair mask) and/or your raw materials?” the fragrance is just for shampoo products but mine is leave on hair conditioner. Ifollow up.
“(adding 1% of the fragrance blend to each material 1 on 1 and see what happens, then add 1% of the fragrance blend to a mixture of 2 materials, etc. etc.).” I really didnt undrestant what u said, material =my hair mask? what do u mean mixture of 2 materials?

damaging process are as the same in both hair but in different severity.
“virgin itself implies something not damaged and hence very little affinity for deposition” why u say virgin is not damaged? my hair is virgin but is far more damaged than a treated hair.
ok I will try that percentages and then say the answer.
-
I want it for a dry and damaged hair, both virgin hair and colored hair can be damaged. u mean I use amodimethicone, its better than other silicones? disteardimonium chloride is behentrimonium chloride?

why u use d-panthenol,hydrolyzed wheat protein for a hand cream? I think sticky feel dues to polysorbate 80 not glycerin.
