I fix hlb 10, the solution is as you said from process.

Thanks a lot for your comment, I wrote full lol but when cream loose viscosity I didn’t add preservative and perfume, about stirring it needs high speed stirring to get good viscosity 600 rpm is low.

MemberSeptember 23, 2024 at 8:16 am in reply to: What is the best actif or combination for whitening cream?I already make a lot of researchment about vitamin c and (Mpg, glycerin) will be choice.
Now the problematic is it will be better to use maximum of solvents enhancers for a synergy or it will be better to use the best (one or two) enhancer(s) alone.

I’am not making massage cream however why massage cream use parrafin oil?
When adding dimethicone 350 to cream the viscosity decrease more. Can you guess why?

Actually I have very close formulation with preolatum instead paraffin oil and I did not face a problem actually I got with petrolatum viscous cream. About recristalisation all solids have fusion temperature far from 70 °C then it can not happen. ( today I just do same process described just increasing the speed of stiring and I got better results.)

MemberSeptember 19, 2024 at 8:34 am in reply to: What is the best actif or combination for whitening cream?Actually it is very expensive ingredient more then all I wrote and it it is more difficult to use in formulation then a lot of others.

I did not add preservative and perfume.

Thanks.
For making cream the order is :
1)heating separately oil and water phase to 70°C(Except perfume and preservative)
2)take both oil and water phase far from heat source(cooling start very fast it needs near to 30 min to reach 40°C)
3)start stiring with 600 rpm speed
4) between 50° C and 40 °C emulsion became thick as usual(stiring 600 rpm) .
5)from 40° C or lower emulsion became thinner( stiring 600 rpm without adding preservative and perfume)
For conditioning hair : the chronology of viscosity is in cooling phase.

MemberSeptember 9, 2024 at 7:36 pm in reply to: What is the best actif or combination for whitening cream?I will not use Gluconolactone (PHA) for stability reason, ph will be in the optimal range of standard cream between 4.8 and 5.3.

Even some proteins and perfumes so for emulsion it Evry ingredient can change the viscosity of your product even dramatically with very low level this is a results of my some experiences.
-
Fine I got the list ingredients then :glycerin, Edta, glycols can make emulsion thinner.

Share the ingredients of industrial mask.
