You are so welcome!

[@lekenyahuddleston7106]

can you do a example like this but with oils. Im trying to learn how to formulate hair growth oil.

[@theinstituteofpersonalcare6401]

Thanks for the suggestion! I’ll see if I can add this to my list! You may also enjoy our Natural hair oil: kzbin.info/www/bejne/qn3WYX1jlJaCrrs :)

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/

Hi Belinda,,Please tell ..if pH is q.s.. Won't it affect 100% or I have to subtract pH amount from 100%..or pH quantity is not counted in 100%. Thankyou

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?

[@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.

Hello, I am looking for someone to help me learn how to calculate how many of each ingredient I need for my specific formula. I watched your videos and they make sense but when I go to my formula, it just doesn't click. Can you help offline?

[@theinstituteofpersonalcare6401]

Learn how to formulate with active ingredients, including how to stabilise them in your formulas and check quality/stability with our Certificate in Advanced Cosmetic Science: personalcarescience.com.au/CosmeticScience/CertificateinAdvancedCosmeticScience-478/ or Diploma of Personal Care Formulation: personalcarescience.com.au/CosmeticScience/DiplomaofPersonalCareFormulation-479/

[@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.
