Hi everyone

I am Stephanie from Malaysia. Unlike many of you all here I have only started working in an oleochemical company a year back. Just recently I have move to the application mainly focusing in cosmetic. I find this blog very interesting. I am also reading Perry’s book Beginning Cosmetic Chemistry. I am looking forward to gain more knowledge from all the experienced people in this blog

Refering to the ingredients above, in your opinion which holds the more responsible in forming a gel?

The copolymer or the glyceryl oleate?

@Bobzchemist Thank you for your input

The below article stated that they measure the gel stiffness in C value penetration

Please have a look

can somebody tell me how is gel stiffness measurement is made?

through rheometer or penetrometer?

and how does the C value quantify the gel stiffness?

Thank you so much for your input

[ssdc]

ok thanks.

can anyone tell me other possibilities of bad performance?

[ssdc]

@bobzchemist I am just guessing. Sometimes the the heavy metal comes from the reactor tank

I have customer complaining that my glyceryl oleate is not giving the same gel stiffness as the previous supplier.

I was just wondering what is the chemistry behind this

[ssdc]

im just studying on the stability of the cream at different pH

[ssdc]

therefore water is produced thus making the cream more diluted?

[ssdc]

care to explain how oil reduce foaming?

[ssdc]

for my esters which has double bond.

any natural antioxidant which is good and do not contribute color?

[ssdc]

thank you so much

[ssdc]

Can you briefly explain about the glass slide test

Thanks

[ssdc]

thank you so much

[ssdc]

suggestions as in where should i start searching for a brand new molecule

thanks

[ssdc]

what i meant was to have a natural alcohol and a natural acid, then react to form a natural ester. Any suggestions?
