Hydroxypinacolone Retinoate เวลาใส่ในสูตรเกิดการตกผลึก

Need help and get help on cosmetics formulation development

Hydroxypinacolone Retinoate crystallized when added to formulations.

Postby wanit_b » Tue Nov 01, 2022 5:28 pm

hello

Tried Perfect-A in both liquid and powder form (dissolved in DMI until clear).
But when put in emulsion in the last step crystallization. It's a yellow streak.
Perfect-A 10™ liquid is also used, so I dropped Perfect-A 10™ in water and it crystallized into a yellow streaky powder as well.

I don't know how to fix it.

thank you

hello


It cannot be dissolved in water directly. must be merged with the formula By mixing with the oil in the formula and then merging, but if the formula uses heat to combine. avoid heat by adding it in the last step then blended together


If added in the last step and sediment is formed Please inform the formula composition. to check
