When a product with extraordinary features launches, it is hard not to shout about it. Koster Keunen has developed Kester K-45, a multifunctional jojoba ester for today’s personal care formulations. It offers non-greasy emolliency, oxidative stability, and a luxurious skin feel. It can be used in both wash off and leave on applications. And the best news of all is the breadth of applicability across all personal care platforms.
Enhancing Product Strengths
In cosmetic chemistry, the feel of a product can make all the difference. The more luxurious the feel, the more likely it is that your brand will be the go-to. Kester K-45 delivers on feel in so many ways:
- Non-greasy sensory profile
- Reduced friction in comb-through products
- Enhanced coverage and payout for color cosmetics
Consumers continue to demand products that meet exacting standards for texture, but are increasingly looking for products with recognizable ingredients, and those that enhance skin naturally. Kester K-45 meets the challenge:
- Derived from natural, recognizable source
- Reduces dryness, roughness, and flakiness
- Supports heathy skin barrier
Bringing the Benefits Home
Each time of year brings its specific stresses for the skin, and this example formulation doesn’t just smooth over the rough spots, it soothes and restores over-stressed skin. Fitting in with current trends for natural and clean skin formulations, Cream with Kester K-45 is light, non-greasy, and best of all, imparts silkiness and glide. White Beeswax brings thickening and gloss to the formula to round out the look and feel of a luxurious skin-enhancing cream.
