Clean beauty is no longer a niche claim. It is redefining how cosmetic products are formulated and marketed. Today's consumers expect transparency, safety, and sustainability — but they also demand visible results and high performance.
This creates a real challenge for formulators: how do you deliver clean formulations without compromising efficacy, sensoriality, or stability?
One category of ingredients is increasingly proving its value: minerals. Thanks to their natural origin, functional versatility, and strong safety profile, mineral ingredients are emerging as a strategic pillar in high-performance clean beauty formulation.

Clean beauty vs. performance: a real formulation tension
The clean beauty movement has accelerated the removal of ingredients perceived as controversial. Yet many of these ingredients historically played important technical roles — as texture enhancers, film formers, mattifying agents, or stabilizers.
At the same time, consumer expectations have not dropped. Products must deliver visible results, pleasant textures, and long-lasting effects.
Minerals resolve a large part of this tension. The global clean beauty market was valued at $8.7 billion in 2023 and is projected to reach $39 billion by 2033, growing at a CAGR of around 16.65%. Within that growth, mineral-based formulations occupy a rare position: they answer both the clean beauty demand and the performance expectations of professional formulators.
Why minerals are shaping the next generation of formulations
Minerals are gaining renewed attention across skincare, suncare, and color cosmetics. The reason is not their natural image alone — it is their ability to deliver consistent, measurable performance within increasingly demanding formulation frameworks.
What makes them particularly valuable today is their multifunctional nature. Within a single ingredient, minerals can absorb excess sebum, refine texture, create optical blurring effects, and contribute to pigmentation, all while maintaining a strong safety profile. In a market where shorter INCI lists have become a differentiator, the ability to do more with fewer ingredients is a decisive advantage.
Their versatility reinforces this position. Minerals adapt easily across applications: skincare treatments and masks, mineral-based sun protection, powder and foundation systems, and hybrid cosmetic formats. This flexibility makes them core formulation components, not niche additions.
As brands move toward greater ingredient transparency, minerals capable of combining performance, sensoriality, and stability are becoming strategic assets. They are not just compatible with clean beauty — they are actively shaping its formulation future.
Clay minerals: multifunctional actives, not just fillers
Clay minerals are among the most versatile tools in the formulator's toolkit. They serve documented functions in cleaning, anti-aging, sebum control, and sun-care applications — far beyond their common reputation as texture agents or fillers.
The family is broad and technically varied. Talc, kaolin, mica, are the most frequently used in cosmetic products, alongside various modified or synthetic clays.
On the performance side, clay minerals with high adsorption capacity — including kaolin, and talc — form a protective film on the skin, adsorb excess sebum and toxins, and increase adhesion of powder preparations.
Kaolin stands out for its regulatory latitude and its versatility. It is accepted in formulations that contact the eyes (up to 8.5% in eye shadows) and in products that may be incidentally ingested (up to 14.5% in lipsticks). As concern around talc grows due to potential asbestos contamination, kaolin provides comparable texture and sebum-absorption performance without the associated risk.
Mica is the primary mineral behind optical effects in color cosmetics: the shimmer and luminosity in eyeshadows, highlighters, and blushes. Sericite, a fine-grained mica variety, improves skin adhesion, extends pigments, and delivers finishes ranging from matte to transparent. Its particle geometry makes it a technically superior alternative to talc in powder foundations.
One formulation consideration applies across the whole clay family: because their sorption potential is high, they can sequester other actives, reduce preservative efficacy, or interfere with fragrance components. Compatibility testing is non-negotiable before finalizing any clay-based system.
Amorphous silica: sensoriality and beyond
Amorphous silica is one of the most formulation-friendly minerals available. It serves three distinct functions depending on how it is deployed. As a sebum absorber, it captures oil and moisture, delivering a mattifying effect suited to oily and combination skin. In powders and creams, it provides a soft, dry, velvety sensory finish that is difficult to replicate with synthetic alternatives. In color cosmetics, it improves pigment dispersion and color stability.
A more recent and technically interesting application involves mesoporous silica nanoparticles (MSNs) as encapsulation vehicles for UV filters. The silica matrix retains UV filters at the skin surface, reducing dermal absorption — a direct response to growing concerns about organic filter penetration. MSNs also prevent agglomeration of TiO2 and ZnO particles through their high surface area and pore uniformity, which improves UV-blocking performance. This positions amorphous silica as both a sensory ingredient and a delivery system in next-generation mineral suncare.
The SCCS opinion on amorphous silica confirms good skin tolerance and no significant penetration through intact skin — a safety profile that, combined with its functional versatility, makes it a consistent choice across product categories.
Physical exfoliants: the return of mineral-based scrubs
Physical exfoliants are making a strong comeback in clean beauty. Consumers are looking for biodegradable alternatives, microplastic-free formulations, and gentle yet effective exfoliation.
Minerals such as perlite are well positioned to meet these expectations. Naturally derived, with controlled particle size for gentle exfoliation and good skin tolerance, perlite is easy to formulate in scrubs and cleansers. It offers a straightforward answer to one of the more visible clean beauty formulation challenges — replacing synthetic microbeads with something that actually works.
Iron oxides: pigmentation and blue light protection
Iron oxides (CI 77491 red, CI 77492 yellow, CI 77499 black) are the dominant pigment family in color cosmetics, present in virtually every foundation, blush, eyeshadow, and tinted skincare product. They are UV-stable and resistant to oxidation, maintaining color integrity over shelf life — an advantage that plant-based pigments cannot match consistently.
UV protection: zinc oxide and titanium dioxide
Zinc oxide (ZnO) and titanium dioxide (TiO2) are the two UV filters classified by the US FDA as Generally Recognized as Safe and Effective (GRASE). No other sunscreen active shares this status in the US market, and both are similarly established under EU Cosmetics Regulation Annex VI.
Their protection mechanism is worth clarifying. Research confirms that TiO2 and ZnO protect primarily via UV absorption, not reflection or scattering — average reflectance across the UV range sits at only 4 to 5%, below SPF 2. Performance depends on particle size, surface coatings, and formulation pH.
TiO2 is more effective across UVB and short-wave UVA. ZnO covers deeper UVA wavelengths associated with photoaging. Used in combination, they deliver broad-spectrum coverage at lower individual concentrations than either filter alone, which reduces the total mineral load in the formula — and therefore the white cast.
Formulation principles for mineral systems
Several practical points are worth drawing out for formulators working with mineral-forward systems.
Particle engineering is where performance lives. The gap between a poorly processed and a well-processed mineral formula is large. Surface treatment, milling precision, and particle size distribution control matter as much as the choice of mineral itself. A zinc oxide formula with optimal dispersion will outperform a poorly milled batch at the same use level on every sensory metric.
Mineral systems support shorter INCI lists. Because minerals are inherently multifunctional — UV filters that also provide texture, clays that mattify and stabilize, iron oxides that pigment and protect — they allow formulators to reduce total ingredient count. This is commercially relevant in markets where consumer label scrutiny has intensified.
Compatibility must be verified systematically. High-adsorption minerals interact with other ingredients in ways that are not always predictable. They can reduce preservative efficacy, sequester fragrance molecules, or modify emulsifier rheology. Formulation order, pH, and processing temperature all influence these interactions. There is no shortcut around compatibility testing.
White cast is a formulation problem, not a categorical one. The 2025 PLOS ONE white cast scoring framework provides a reproducible optimization method based on L* values across ITA° skin tone subtypes. The problem is technical and solvable.
What comes next: the innovation frontier for mineral formulation
The most active development space in mineral cosmetics sits at the intersection of performance and delivery technology: encapsulated minerals, surface-functionalized particles, and hybrid systems combining minerals with biotechnology-derived actives. These approaches preserve the clean positioning of minerals while directly addressing their historical limitations in texture, coverage, and sensory finish.
A 2024 study published via the National Library of Medicine found that 40% of consumers are now aware of potential health impacts linked to synthetic cosmetic ingredients, sustaining demand for earth-derived raw materials. For innovation teams, this is not a passing trend — it is a structural shift in how products are developed and positioned.
The technical case for minerals in clean beauty is solid. The formulation challenges are real but solvable. For R&D teams navigating a more constrained ingredient environment, mineral-based systems deserve systematic evaluation — not as a compromise, but as a primary formulation strategy.
