- Benefits of Versastique Products
- Formulation Friendly – efficient delivery system, easy to use (simply melt and mix).
- Cost Effective – reduces amount of structural material required to make a stick application.
- Versatility – compatible with a wide variety of low polarity ingredients.
- Performance – excellent suspension properties and superior moisture delivery.
- Stability – stabilizes and protects active ingredients in a self-preserving formulation base.
- No harsh chemicals – milder to the skin and low toxicity.
- Formulating Sticks with Versastique Low Melt
The major challenge in formulating stick products is balancing good in-use and mold release properties with physical and chemical stability. Making the stick too hard with high melting point waxes can provide good heat stability, but often results in poor application (transfer rate or payout) on skin. Using Versastique in your formulation can significantly reduce friction while maintaining sufficient payout — without sacrificing stability of your stick products.
Formulating stick products typically involve heating the ingredients to a molten state to facilitate thorough mixing followed by extrusion or pouring. A lower melting point product base allows incorporation of heat sensitive and volatile ingredients while also
providing a safer processing temperature. Additionally, the higher flash point of the Versastique Low Melt series enables an even greater margin of safety by increasing the difference between the processing temperature and the flash point.

- Versastique™ A Better Way to Formulate
Our gelled technology is used in thousands of cosmetic, pharmaceutical and personal care products around the world. Our process gels various substrates in such a way that it promotes superior moisture retention by creating a continuous film enabling oil to be easily spread with no pooling of the product.
- Creates a film barrier for added moisturization, delivers superior stabilization and suspension properties.
- Provides enhanced fragrance retention and waterproofing properties.
- Versagel MX meets the EU Colipa Lip Care Requirements.
- Lip Care
- The lip’s exposed membrane structure is different from other skin. Lips do not have the many protective layers of stratum corneum that is found in other skin. Lips also do not have the protection provided by the sweat glands and oil glands. Therefore, the lips are more vulnerable to any exposure to natural elements such as wind, cold, sun, etc. Long-term negligence of the lips will result in chapping, cracking, bleeding and the appearance of premature aging. Because of the structure of their skin, lips require consistent moisturization and protection if they are subject to exposure. We take these needs into account to help us produce our Drakeol® Mineral Oil, Petrolatum, VersastiqueTM and Versagel® that are used in lip care applications.

Technical Details & Test Data
- Formulation Benefits with Versastique™ product
Studies on the Versastique product line have shown that prototype formulations using Versastique Clear 5T series SQ, ME, and M have similar hardness, friction, transfer rate and efficacy. This enables formula customization by varying the properties of the gelled emollient. To illustrate the benefits of formulating with Versastique sunscreen prototypes were developed and compared to marketed benchmarks (SB, BG and NK) using a Texture Analyzer.
Hardness
Versastique prototypes have lower hardness than wax structured benchmarks. Softer
stick products are gentler to apply onto the skin.Friction
Versastique prototypes have comparable or much lower friction than the benchmarks. Thus, we can conclude that the Versastique prototypes take less force to spread product over the surface. Additionally, the Versastique ME is the most lubricious.
Transfer Rate
Versastique sunscreen prototypes have similar transfer rates compared to BG & NK while SB is significantly lower. Thus, we can conclude that the amount of product being applied is equivalent to benchmarks. This means that Versastique sunscreens are gentler to apply without applying excess product to the skin.
Efficacy
Figure 1: Broad Spectrum SPF Efficacy (UVA/UVB)
Figure 2: Dry & Water Resistant In-Vitro SPF
Versastique sunscreen prototypes have comparable performance to the benchmark under static and water immersion testing at almost half the active level. All Versastique sunscreens have higher SPF than expected (50 vs. 30) which implies highly uniform spreading of the sunscreen agents in Versastique base. Versastique sunscreens showed broad-spectrum performance with each having a UVA/UVB ratio greater than 0.90 (Figure 1). The pre-emersion or static SPF of Versastique sunscreens is comparable to static SPF of the benchmark while the post-emersion SPF is within 80% or greater of the benchmark value. The water-resistant properties of Versastique enable higher SPF post-immersion vs. the static or pre-immersion values. The mildness, high efficiency, and water resistance of Versastique makes it an attractive base for high performance sunscreens (Figure 2).
