Thanks ❤❤❤very useful and informative

[@jojobee228]

thank you for the video, btw, what is the eco grade of Euxyl PE 9010 Preservative? Also if it's possible for you to demonstrate how to buffer geogard Ultra with sodium citrate to prevent PH drifting? Lonza recommend using 1.5x sodium citrate, then adjust back with sodium hydroxide and lock at 5.4-5.5 as final PH. What's the reason for locking at 5.4-5.5? what about locking at a lower PH like 4.5? I cannot find a single video online showing the buffer process and I'm not confident of using geogard Ultra. Thanks in advance 😊

The natural ph of our skin is between 5.0 to 5.4/5.5- the older the human being the higher the ph value of the skin as a general rule. ph of 4.5 is too acidic for the skin of our faces, but it is the ph value of our hair.

@@jp-legal No you are wrong, the natural skin PH is at 4.5 -5.5. The ideal skin PH is at below 5, there are many research paper support this. Higher pH weakens the skin's acid mantle, making it more vulnerable to damage and prone to common issues like dryness, irritation and sensitivity

Hello thanks for the info! I have the euxyl k903 but it smells so strong using it at 1% , do you know how this could be avoided?

[@ThankYouJesusTheChrist]

HAve you heard of Simply Ingredients? They have a preservative made of the exact same two ingredients as Euxyl and there is no sent whatsoever.

[@theinstituteofpersonalcare6401]

You can try reducing input, use a different preservative or add something in your formula to mask that smell. Learn all about preservatives in our certificate in cosmetic preservatives: personalcarescience.com.au/CosmeticScience/CertificateinCosmeticPreservatives-7431/

[@PerryRomanowski]

Yes, DMDM Hydantoin is a good preservative. It's an industry standard and what people typically used before "natural" and "clean" fear marketing stories took over the industry. Methylparaben is great too.
