1 Surprising Csmetic Functinal Benefits f Plant Wax Butters Dr. Yn Gattefssé

2 Natural Skincare Textures getting better Increase f available emllients Sensatin f insufficient misturizatin & cmfrt Heavy feel vs nurishing efficacy

3 Why lk at waxes? Majr barrier against water lss Renewable surce Excellent safety prfile Prperties very different t vegetable ils & butters

4 Wrld prductin f waxes Availability & cst? Quality? Lw MW plylefins Paraffins (petrleum) 1% animal 2% vegetable 75-85% Synthetic waxes 10-15% Natural waxes Apple peel range peel Carnauba Candelilla Jjba Sunflwer Rice bran Sugar cane Jasmin Mimsa Beeswax

5 Chice f waxes Candelilla Euphrbia cerifera True artisanal wax Hard, film frming, barrier prperties 40-50% hydrcarbns (C29-33), high MW saturated esters, fatty alchls & acids, sterls Fd additive, lipsticks, pencils Rice bran ryza sativa Fd industry c-prduct Hard, high MP wax (80 C), builds viscsity Lng chain mn-esters Used in csmetics and in fd as a cating

6 Chice f waxes Simmndsia chinensis Liquid wax 97% esters mainly unsaturated (C40-44) Frequent use in csmetics & pharmaceuticals Jjba Sunflwer seed Mimsa Helianthus Annuus Fd industry c-prduct Hard, high MP wax, excellent thermal stability High carbn fully saturated mn-esters (C38-54) Acacia decurrens C-prduct f perfumery Sft wax, gd viscsity builder, MP 61 C Lng chain esters, hydrcarbns, triterpenid alchls, free fatty acids

7 Frmulatin difficulties High temperature required Slubility issues Recrystallizatin & destabilizatin /W emulsin withut waxes /W emulsin with 5% candelilla wax

8 Sensrial prperties in emulsin Sensrial analysis plt Sft afterfeel Thickness Spreadability Frmula with 5% Candelilla wax Placeb Frmula Tacky afterfeel Sftness upn applicatin with wax Film residue Greasiness Requires imprvement

9 Transfrming waxes Maintain basic chemistry Imprve frmulability & slubility Imprve sensrial prperties Respect Principles f Green Chemistry* *Jhn C. Warner & Paul T. Anastas,1998
