When making samples for formulating, does it have to be 100 grams or can we go smaller than this, so that we can create a sample size of 1 oz instead?

[@theinstituteofpersonalcare6401]

It should be to 100 grams; and is much easier if you use grams rather than ounces because the formulas are written to 100% - so 100% translates easily into 100g. Please watch this video on how to write cosmetic formulas: kzbin.info/www/bejne/gWGaaISCqpKMea8 and you may also be interested in our FREE Masterclass: personalcarescience.com.au/Workshops/CosmeticFormulationFundamentalsMasterclass-7441/

[@juliemitchell4739]

So once we have our grams for our formulas how do we calculate how much raw ingredients to purchase? Suppliers sometimes use other measurements than grams.

Hi, i know this out of topic, but may I ask of peg-40 hdrogenated castor oil is tasteless and odorless? Or is it bitter and smells bad?

[@theinstituteofpersonalcare6401]

Thanks for watching! It is odorless, I haven’t tasted it to comment on bitterness.

[@eph9434]

@@theinstituteofpersonalcare6401 is it safe for lip use? Or does it have to be food grade?

[@godivanubian995]

I have lip scrub recipe that I love but it’s not 100 percent it’s maybe 500 grams what should I do?

[@theinstituteofpersonalcare6401]

To help you with this specifically, we would need to get full details of your formula and specifications of specific materials. This would take time to review and advise on properly, please purchase consulting time here: personalcarescience.com.au/Advice/Advice-2046/ so we can advise you properly on your specific situation.

[@bayside833]

Okay holy shit this is awesome …. So if I have 3 essential oils for a candle. Say 35 drops in total . I have to weigh each essential oil by grams to determine how much of each is weighted in grams before I can do a bigger batch? Like 6 drops of lavender.. Weigh how much that is by the gram?

[@theinstituteofpersonalcare6401]

You need to weigh them as every different oil drop weighs slightly different differently. So get your current volume measurements, and weigh them, then convert it to a % formula. Then it will be really accurate moving forward.
