The ZinClear® Dispersions Range: Carrier Oils & Additive Systems Explained

Updated: 10 minutes ago

Formulating mineral sunscreens requires more than choosing the right zinc oxide. The carrier oil and additive system surrounding the particles strongly influence a product’s sensory feel, viscosity, film uniformity and compatibility with other ingredients. Because formulations differ widely — from fluid SPFs to rich balms — Advance ZincTek offers a diverse portfolio of ZinClear® dispersions to give formulators precise control over performance outcomes.


This article summarises the key functions of our carrier oils, the purpose of common additive systems, and how ZinClear® grade numbers translate into practical formulation choices.

1. The Role of Carrier Oils in Mineral Sunscreen Formulation


Carrier oils determine how zinc oxide disperses, spreads on the skin and behaves in an emulsion. Variations in polarity, viscosity and volatility influence:


  • glide and slip

  • pigment wetting

  • emulsion stability

  • compatibility with UV filters and other oil-phase ingredients

  • sensory finish (dry, silky, rich, light)


Because the sensory expectations of a face lotion differ from those of a balm or sport SPF, multiple carrier options ensure formulators can achieve the intended texture and performance.



2. Carrier Oil Families and Their Formulation Benefits


A lightweight, fast-absorbing ester ideal for smooth, non-greasy formulas. It wets pigments effectively and supports fluid emulsions and daily facial SPF textures.


A medium-polarity triglyceride offering balanced slip and excellent oxidative stability. Its reliable pigment wetting makes it suitable for everyday sunscreens, creams and sensitive-skin formulas.


A plant-derived ester with a dry, “silicone-like” feel. Perfect for natural or silicone-free formulations, lightweight milks and high-spread emulsions.


A liquid wax ester with high skin compatibility and a cushiony, premium feel. Suitable for skincare–sunscreen hybrids, serums and sensitive-skin products.


Light to medium sensory profile with good oxidative stability. Works well for everyday SPFs requiring balanced sensory and dispersion performance.


A natural triglyceride with a smooth, gentle feel. Ideal for natural-leaning sunscreens, mild dermatological products and sensitive-skin formats.



4. Understanding ZinClear® Grade Numbers


Grade numbers broadly reflect zinc oxide concentration paired with specific oils and additive systems:


  • Higher numbers (XP65, XP70): higher zinc oxide loads for sticks, balms, high-SPF formats

  • Mid-range (XP47, XP52): balanced concentrations for everyday creams and lotions


This system gives formulators a straightforward way to choose the viscosity, sensory profile and ZnO load appropriate for their application.



5. Choosing the Right Dispersion for Your Application


  • Lightweight facial SPFs: alkyl benzoate dispersions, often paired with TES or PDMS for smooth spreading and uniform film formation.

  • Everyday creams & family SPFs: CCT or MCT systems for balanced sensory feel and reliable stability.

  • Natural or silicone-free markets: coco-caprylate dispersions or systems incorporating SGLu/SGa.

  • Premium skincare–SPF hybrids: jojoba-based systems for a luxurious, cushiony finish.

  • Natural-positioned dermatological formats: sunflower-oil dispersions.


These are common formulation patterns, not strict limitations. ZinClear® dispersions are flexible and can be adapted to a wide variety of emulsion and anhydrous structures.



6. Final Thoughts


Advance ZincTek’s ZinClear® dispersion range is built to help formulators meet diverse sensory and performance requirements in mineral sunscreen development. By combining carefully selected carrier oils with targeted additive systems, each grade delivers a balanced profile of stability, texture and dispersion efficiency.


As demand for mineral UV filters grows, choosing the right dispersion can streamline development, improve consistency and support high-performing, consumer-friendly sunscreens. From lightweight facial fluids to robust sport SPFs, the ZinClear® range provides the flexibility formulators need to work with confidence.
