K-Beauty Sunscreen Filters: Uvinul, Tinosorb, and INCI Names Explained

Uvinul and Tinosorb are trade names, not the names most shoppers will find in a complete ingredient list. This guide translates common K-Beauty sunscreen filter names into INCI, then keeps that identity separate from the tested SPF, UVA claim, texture, and wear of a finished product.

Trade name, INCI, and product claim are three different layers

A trade name identifies a supplier's ingredient product. INCI is the standardized ingredient name used to identify material on a cosmetic list. SPF, broad-spectrum, PA, water-resistance, and similar claims belong to the finished sunscreen sold in a particular market. Moving from one layer to the next requires evidence; a familiar trade name cannot supply the missing test result.

Start with the exact package and regional formula. Then translate any shorthand into the printed INCI name. The regional formula guide explains why a familiar product name may lead to a different list or label in another market.

Translate the filter names you see most often

• Uvinul A Plus: Diethylamino Hydroxybenzoyl Hexyl Benzoate, commonly shortened to DHHB. BASF includes it in its photostable-filter series. Open DHHB in the Atlas.
• Uvinul T 150: Ethylhexyl Triazone, commonly shortened to EHT. BASF identifies it as a UVB filter. Open Ethylhexyl Triazone in the Atlas.
• Tinosorb S: Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, also called bemotrizinol or BEMT. BASF describes it as a broad-range UVA and UVB filter. Open Tinosorb S in the Atlas.
• Tinosorb M: Methylene Bis-Benzotriazolyl Tetramethylbutylphenol, also called bisoctrizole or MBBT. A supplied dispersion can list MBBT with its water, dispersant, and stabilizing materials. Open MBBT in the Atlas.
• DBT: Diethylhexyl Butamido Triazone, also called iscotrizinol. It is an INCI and technical abbreviation rather than one of the Uvinul or Tinosorb trade names. Open DBT in the Atlas.

These mappings help you recognize the same material under different vocabulary. They do not show how much was used, whether a supplier blend has additional components, or how the complete sunscreen was dispersed, stabilized, preserved, packaged, and tested.

What a filter list can tell you

A current list can identify which named UV filters are present and help you compare two regional formulas. Supplier documentation can explain whether an individual material is designed for UVA, UVB, broader coverage, or photostability. That is useful formula context, especially when a retailer uses trade-name shorthand while the package uses INCI.

A cosmetic-style INCI list can also document position, but it is not an exact concentration unless the manufacturer declares one. Lower-list ordering rules and regional sunscreen label formats can differ, making a filter-count or position ranking even less informative than it first appears. Read the INCI guide before comparing positions across products.

What the list cannot calculate

• It cannot reproduce the finished product's tested SPF or UVA protection.
• It cannot prove broad-spectrum, PA, water-resistance, or wear claims for your market.
• It cannot reveal undeclared concentrations, particle form, dispersion, film uniformity, or package performance.
• It cannot predict how much a person will apply, how evenly it will spread, or when it will be removed by water, sweat, or rubbing.
• It cannot establish individual compatibility, eye comfort, white cast, or irritation.

FDA guidance ties SPF and broad-spectrum labeling to finished-product testing. Even a formulator's technical estimate uses concentration and system assumptions that a retail INCI list does not provide. For a shopper, the current tested label and directions remain the decision layer.

Read one reviewed formula: Beauty of Joseon Relief Sun

The Atlas record for Beauty of Joseon Relief Sun: Rice + Probiotics captures a global-English formula reviewed on July 20, 2026. That source snapshot maps DHHB at INCI position 4, Ethylhexyl Triazone at 6, MBBT at 7, and Diethylhexyl Butamido Triazone at 11.

This reviewed list does not show Tinosorb S. It is therefore more accurate to name the four mapped filters than to repeat a generic “Uvinul and Tinosorb” story from an old post. The positions still do not calculate SPF50+ or PA++++. Those are finished-product claims to confirm on the current regional package, alongside directions and any water-resistance statement.

Use a five-check sunscreen workflow

1. Identity: match the exact product, package, size, and market.
2. Label: read the tested protection claims and current directions before the filter story.
3. INCI: translate trade names into exact printed ingredient names without guessing concentration.
4. Use: choose a finish you can apply adequately and reapply as directed.
5. Verify: revisit the official page and package after a reformulation or regulatory change.

The label and application guide covers application, reapplication, water resistance, and broader sun-protective behavior. Filter literacy is a companion to that workflow, not a replacement for it.

Use the graph as an identity map, not a protection score

Ingredient nodes can show which reviewed products contain a mapped filter and which formula companions appear in those records. A connection does not mean equal concentration, equal protection, or a recommended combination. Confirm the formula source and date on the detail page before carrying a graph observation into a purchase decision.
