Navigating the Clean Label Movement: What It Means for Formulators

Posted by CapsCanada on 8-Jul-2025 5:11:57 PM

The clean label movement now shapes how products are formulated, packaged, and marketed, extending all the way to the capsule shell. In today’s market, transparency, simplicity, and natural ingredients are no longer optional, they are strategic differentiators.

While there’s no official regulatory definition, “clean label” typically refers to formulations free from artificial additives, GMOs, preservatives, and synthetic colorants. Research shows that 81% of consumers globally prioritize clean-label products, making it essential for brands to examine every component of a formulation, including the delivery system.

 

What’s Driving the Demand for Clean Label Capsules?

 

Several converging factors are accelerating clean-label adoption in the supplement industry:

  • Health & Ingredient Literacy: Consumers are more informed, actively researching ingredients and seeking formulations aligned with their health values.
  • Ethical and Environmental Preferences: Plant-based and animal-free capsules resonate with vegan consumers and support sustainability narratives.
  • Regulatory Pressures: In 2022, the European Union officially banned titanium dioxide (TiO₂) in food and supplements, citing safety concerns. Although TiO₂ is still permitted in the U.S. and Canada, this regulatory divergence signals an international shift.
    In the U.S., regulatory scrutiny is intensifying: the FDA recently moved to ban Red No. 3, long used in foods, supplements, and pharmaceuticals, citing potential cancer risks. This action reflects a broader trend, with additional synthetic dyes now under FDA review and increasing pressure from consumer advocacy groups.

For manufacturers, anticipating these regulatory shifts is not just about compliance, it’s a strategic move to ensure product continuity, global market access, and consumer trust.

 

Vegetarian Capsules in Clean Label Strategies

 

Two-piece capsules, especially those made from HPMC, offer clear functional, regulatory and marketing advantages over tablets and softgels in clean-label formulations. Benefits include: 

  • Low moisture content: Ideal for hygroscopic or moisture-sensitive ingredients.
  • Fewer excipients: No need for binders, coatings, or gelatin-based stabilizers.
  • Excellent disintegration: Within 15 minutes for immediate-release profiles.
  • Appearance with clearer transparency or fully customizable design.

    CapsCanada offers two clean-label HPMC capsule options, each tailored to specific formulation needs:


  • K-CAPS®: These capsules are made from plant-derived HPMC. They are free from animal byproducts, GMOs, allergens, preservatives, and synthetic colorants. K-CAPS® are Registered by the Vegan Society, and kosher, and halal certified, making them suitable for global markets with diverse dietary and regulatory requirements. Available in a wide selection of natural colorants, without compromising clean label claims.


  • K-CAPS® Delayed-Release: Developed specifically to protect acid-sensitive ingredients, these capsules feature a pH-sensitive polymer matrix that enables content release in the intestines rather than the stomach. This makes it ideal for probiotics, enzymes, and formulations targeting gut delivery. Unlike standard K-CAPS®, the delayed-release version offers enteric protection without requiring additional coatings, simplifying production while maintaining clean-label integrity.

Together, these capsule solutions allow formulators to select the right delivery profile, whether immediate or delayed, while maintaining alignment with clean-label expectations.

 

Natural Colorants in Capsules: Technical Precision, Visual Impact

 

Replacing synthetic dyes with plant-based pigments is a core strategy in clean-label development. Consumers now closely associate natural coloring with purity, safety, and transparency.

CapsCanada offers a diverse portfolio of natural colorants that eliminate the need for artificial dyes without compromising capsule performance. These pigments maintain disintegration, stability, and machinability, while supporting claims like “no artificial colors.”

 

 

Reformulating Without Titanium Dioxide: A Global Market Imperative

 

Titanium dioxide has long been used in capsules to enhance whiteness and opacity. However, following EFSA’s updated safety assessment, the EU classified TiO₂ as “no longer considered safe” for ingestion, leading to its removal from food and supplements. While TiO₂ is still permitted at levels below 1% in the U.S. and Canada, global momentum is clearly moving away from its use.

CapsCanada’s TiO₂-free capsule options, including K-CAPS® and G-CAPS®, use natural mineral opacifiers like calcium carbonate to maintain:

  • Opacity and visual uniformity
  • Disintegration performance
  • Shelf-life stability

Clean Label as the New Industry Standard

 

Clean labeling is redefining standards in the supplement industry. Consumers now inspect inactive ingredients with the same rigor as active ingredients, and regulators are stepping up oversight of excipients that were long considered benign. Brands that respond proactively to this change can build long-term trust and expand their consumer base.

CapsCanada’s capsule technologies, such as K-CAPS®HPMC, K-CAPS® Delayed Release,  TiO₂-free capsules and naturally pigmented options, offer a comprehensive platform for clean-label formulation without sacrificing performance. By integrating these solutions early in the development process, you can deliver products that are effective, compliant, and aligned with the expectations of today's health-conscious buyer.
