Zinc White (ZINC OXIDE)
Commonly Found In
Overview
Zinc oxide is an inorganic mineral compound that functions as a broad-spectrum UV filter, white colorant, and skin-protective agent widely used in sunscreens, mineral makeup, and diaper care products. As a physical (mineral) UV filter, it reflects and scatters both UVA and UVB radiation across a broader spectrum than most organic UV filters, making it particularly valuable for comprehensive sun protection. Studies suggest zinc oxide also exhibits antimicrobial and mild anti-inflammatory properties, contributing to its long-standing use in products targeting acne-prone, sensitive, and barrier-compromised skin. Both nano and non-nano forms are available; non-nano particles tend to leave a white cast on skin while nano-grade particles are more cosmetically elegant but are subject to additional regulatory labeling requirements in the EU.
Also known as: ZnO, Zinc White, Philosopher's Wool, Chinese White, Calamine (in combination with iron oxide), Mineral Zinc
Key Benefits
Studies suggest zinc oxide provides broad-spectrum UVA/UVB protection, with a UV absorption range extending to approximately 380 nmβwider than most organic filters. Clinical evidence indicates mild antimicrobial and anti-inflammatory properties that may be beneficial for acne-prone skin. Zinc ions released from the compound may help regulate sebum production and reduce Cutibacterium acnes activity.

Irritancy Rating
Well-tolerated by most skin types including sensitive skin. Nano-form safety is separately assessed; EU requires nano labeling but SCCS considers nano ZnO safe in sunscreens.

2-25%
Optimal
10-20% (for sunscreen efficacy)
FDA classifies zinc oxide as a Category I (safe and effective) OTC sunscreen active at 2-25%. Lower concentrations used in skin-protective and makeup applications.

Global Regulation Summary
Overview of current status across major international markets.
Detailed Regional Status
| Region | Status | Max Conc. | Conditions | Source |
|---|---|---|---|---|
| πͺπΊ EU | Allowed | - | - | Official β |
| πΊπΈ USA | Allowed | - | - | Official β |
| π―π΅ Japan | Allowed | - | - | Official β |
| π°π· Korea | Restricted | 25% | When used as UV protection | Official β |
| π¬π§ UK | Banned | - | Follows EU regulations (IV/144 VI/30 VI/30a) | Official β |
π Why Regulations Differ
The FDA classifies zinc oxide as an OTC drug active ingredient (as a sunscreen) in the US, permitting up to 25% with established monograph status. The EU regulates it as a UV filter under Annex VI of the Cosmetics Regulation, and requires nano-form particles to be labeled as '[nano]' since 2013 following SCCS safety assessment. Japan allows zinc oxide as a quasi-drug sunscreen UV filter. South Korea restricts its use to sunscreen applications up to 25%. The UK post-Brexit classification is complex; zinc oxide appears in UK Annex IV/144 and VI/30 entries governing colorants and UV filters, which the UK retained from EU law.
Recent Regulatory Changes
- β’ EU SCCS Opinion SCCS/1516/13 (2012) confirmed safety of nano zinc oxide in sunscreens with β€25% concentration.
- β’ EU mandatory nano labeling requirement effective July 2013 per Regulation (EC) No 1223/2009 Article 19(1)(g).

Category Comparison
There are 84 ingredients in the ANTIMICROBIAL category. 99% are banned in at least one major market.
Strictness Ranking
πΏ Natural Sources
Found in the mineral zincite, though naturally occurring deposits are rare. Primarily produced from zinc metal ores.
π How It's Made
Produced by burning zinc metal in air (French process) or through wet chemical precipitation from zinc salt solutions. Can be manufactured in nano and non-nano sizes.
π Uses in Cosmetics
Used at up to 25% in sunscreens as a physical UV filter providing broad-spectrum protection. Also used in diaper rash creams, calamine lotion, and as a white pigment in makeup.
π¬ Other Applications
Used in rubber vulcanization, as a dietary zinc supplement, in paints and coatings, and as a semiconductor material.
π‘ Fun Facts
- β’ Zinc oxide has been used medicinally since ancient times; ancient Egyptians used it in ointments
- β’ It's one of only two UV filters (along with titanium dioxide) that can be labeled as 'natural' or 'mineral' sunscreen
- β’ The white paste lifeguards wear on their noses is typically high-concentration zinc oxide
