Hello,

I want to ask about the rancid smell from น้ำมันดอกคำฝอย , as indicated in the description, may smell rancid if mixed in สูตรเครื่องสำอาง will make that makeup smell rancid?

smell น้ำมันธรรมชาติ is inevitable. If used at a high rate It will have a rancid smell. unless there is a filling น้ำหอม came to help cover up the smell

and would like to inquire about Shelf Life at indicated in each ingredient. that if mixed in cosmetics It will last as stated in the ingredients. Or will it be from the date of mixing the cosmetics

according to the current standard is calculated from the date of production of the said lot of cosmetics? by the period that will be from the date of manufacture Usually it is set at 1-2 years. This period is estimated from the accelerated test, for example, put it in the oven at 45 degrees for 1 month.
