Anti-Aging
Solid stick form of squalane derived from plant sugar is a sustainable replacement for shark and olive squalene. It closely mimics the body’s natural moisturizers and is absorbed quickly and effectively, without leaving greasy residue on the skin.
- 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.

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).
