When you formulate cosmetic products in stick form, you are putting together a system that is portable, stable, and has ease of use written all over it. Plus, the market for stick products is especially hot right now.
With that in mind, looking for the right structuring ingredients could give you pause—until you get familiar with the versatility inherent in sunflower wax. As petrochemicals come increasingly under scrutiny in cosmetics, the time is right to examine the broad compatibility of sunflower wax in a wide array of applications.
Sunflower wax provides structure to many anhydrous systems, regardless of oil medium or presence of pigments or powders. Even at low percentages, sunflower wax can improve high temperature stability, preserve stick integrity, and offset a tacky feel. For these reasons, sunflower wax is the wax of choice to create hard sticks, including lip balms, lipsticks, and deodorants. It can also be used as a replacement for typical “no list” ingredients, such as polyethylene, paraffin and other petrochemical waxes.
In study after study, Koster Keunen found that sunflower wax performed consistently in gel formation—a necessity when forming cosmetic stick products. The results were not limited by oil origin, either. Sunflower wax performed equally well across a broad spectrum of popular oil mediums.
