It would help if you told us why you’d like to substitute it.
Price? performance? PEG-free? Not available?

? Amazon came up with >2000 results
However if you want to measure it precisely (for QC) you need to titrate

While brookfield is “right” choice - I wonder if anybody ever tried a cheaper one like this one? Do they work, or is it a waste of money?

Thank you all !- I feel a bit more comfortable regarding this project now.

[David]

Thanks Bill_Toge

ashish: how did you get peroxide formation?

I am not so worried about the powder itself - I use of course standard protection like gloves mask and safety glasses . What I am worried about is whether this mixture can ignite or explode in a simple kitchen blender like this one:

Totally agree with perspicacious! A “real” lab in action usually looks terrible on picture! To take one descent pic for a website you will need days of rearranging, tidying up and preparing the light situation + hire a professional photographer. Secondly - nobody “steals” pics from google - we/they purchase pics which best relate to their businesses.

thanks Belassi - you are right - I try to search elsewhere -  I feel neither my (old) inorganic chemistry courses or usual cosmetic chemistry knowledge is enough here.

[David]

@ Bill_Toge :thanks, specialist advice is exactly what I am seeking!

I should have added I am only interested in lab-scale formulating - Do I need special equipment for that?

It doesn’t seem to have any alarming hazards lab-scale

I know it is hazardous to produce and fill it.

One reason to add antioxidants is to prevent rancidity due to the inherent instability of double bonds in fatty acids.

It still remains a bit fuzzy. What do we mean with that a cream “works”. Is it that is sells?, is it that many customers are happy? Is it that the internal personnel note a difference? Or does the active ingredient have to be “proven” in a peer reviewed paper?

[David]

check this by the beauty brains:

True Bobzchemist but basically all marketing is about how special the formulation is. No one will ever market a product as “this is a standard formula but with great marketing so buy it” 

Therefore this reasoning ends up in a loop.

[David]

I would perform a “professional” dermatological test i.e. a patch testing. Testing on animals is not allowed.

[David]

I bought a second hand Binder. Works perfect, but as Bobzchemist stated you need to be a bit more precise. How large? Is it for professional use?

From CIR:

As evidenced in this safety assessment, numerous studies
have been performed to investigate whether or not a causative relationship
exists between the cosmetic use of talc in the perineal area and ovarian
cancer. The Panel reviewed these studies thoroughly, and determined that they
do not support a causal link. The Panel stated that causation would depend on
the migration of talc from the perineum to the ovaries. There is no conclusive
explanation for the presence of talc in the ovaries reported in some studies.
However, the Panel agreed that there is no known physiological mechanism by
which talc can plausibly migrate from the perineum to the ovaries. Further, the
Panel noted that if typical perineal applications of talc increased the risk of
ovarian cancer, then it would be expected to increase the risks of uterine and,
especially, cervical cancer as well; the absence of reports of associations
between perineal talc use and either uterine or cervical cancer indicates that
perineal talc application does not cause ovarian cancer. Additional support for
this conclusion comes from, for example, studies demonstrating that the use of
talc-dusted condoms or diaphragms, which would clearly result in exposure close
to the cervical opening, was generally not associated with increased relative
risk estimates for ovarian cancer.

Agree with Perry - I wonder how you came to the conclusion to use 3 quats + 2 silicones in a conditioner?

 What the formula lacks is a foam stabilizer/thickener like the good ol’ cocamide DEA. Since it is not so popular anymore I would check out some alternatives like Amidet N.

[David]

Well if you are from Sweden,like me ,  try the Elfan® AT 84 G from akzo. It dissolves just fine when you heat it a bit.  mvh/David

[David]

thanks Bill_Toge - I hope so. 

[David]

I should also have mentioned that the left one was stored @ 40C for a month- the right one @RT 1 month. The bubbles were not possible to see directly after filling (or were very small) - they kind of “grew” after a while - that is why I was considering emulsion instability.

@  Perry Seems that no one can see my pic except me! How to insert a pic properly?
