Related names and forms: Octyl Triazone. This list does not indicate synonyms or exact ingredient matches.
Uvinul T 150 (INCI: Ethylhexyl Triazone; also Octyl Triazone) is among the filters with the highest known UVB absorption efficiency. Its high molar absorption gives a strong UVB contribution at relatively low concentrations, enabling lightweight, cosmetically elegant formulas. It is oil-soluble and photostable. Labels show 'Ethylhexyl Triazone'. It works only in UVB; broad-spectrum coverage always requires a complementary UVA filter such as Uvinul A Plus, avobenzone or Tinosorb. Being used at a low dose does not mean weak protection: high efficiency lets a small amount provide a strong UVB contribution. Assuming direct proportionality between dose and protective strength is misleading. For a product containing Uvinul T 150, Klaris considers UVB efficiency, complementary UVA filters for a broad spectrum and texture together.
i. Cosmetic Functions
Frequently Discussed Effects
The following headings summarise areas of effect frequently discussed in the literature; visible results in each area require regular use and a suitable formula.
Highly Efficient UVB Protection
A photostable filter providing strong absorption in UVB.
Effects at Low Doses
Can contribute strong UVB protection at relatively low concentrations, allowing lightweight textures.
Suited to Combinations
A UVB ingredient suited to building a broad spectrum alongside UVA filters.
Mechanism
What Happens Within the Skin?
The following points summarise mechanisms from dermocosmetic literature in plain English. Klaris presents them as background information to help readers understand the context, not as medical claims.
Step 1
Highly Efficient UVB Absorption
Has very high molar absorption in UVB, explaining its strong contribution at small amounts.
Step 2
Effects at Low Doses
High efficiency provides a strong UVB contribution at relatively low concentrations, enabling lightweight, elegant formulas.
Step 3
High Photostability
Its light-resistant structure helps the system support UVB protection throughout the day.
Step 4
Oil Solubility
Dissolves in the oil phase and suits lightweight systems with other oil-soluble filters.
ii. Role in the Formula
How Is It Read on a Label?
Uvinul T 150 is a highly efficient, oil-soluble UVB filter regulated by cosmetic legislation. It is used with UVA filters for a broad spectrum. Conditions of use are assessed within formula and market regulations.
A Closer Look · pH, Stability, Synergy
Uvinul T 150 is described as a UVB 'efficiency champion': high molar absorption gives a strong UVB contribution at relatively low concentrations, allowing formulators to pursue high SPF while retaining a lightweight, transparent texture. Oil solubility and photostability make it common in modern sunscreens. Because it works only in UVB, broad-spectrum coverage requires a UVA filter such as Uvinul A Plus, avobenzone or Tinosorb S/M. It is not considered sufficient alone for a broad-spectrum claim. A common misconception assumes that an ingredient used at a low dose offers weak protection. Uvinul T 150's efficiency means a low dose can coexist with a strong UVB contribution; direct proportionality between dose and protective strength is misleading. Regional regulations may differ, so Klaris describes conditions in general terms without unsourced specific limits. Newer-generation filters are discussed in a low-irritation context for sensitive profiles; patch testing a new product is measured. For a product containing Uvinul T 150, Klaris considers UVB efficiency, complementary UVA coverage, broad-spectrum balance and texture as a whole.

iii. Sensitivity Advisory
A Note on Extra Care in Context
Newer-generation filters are generally described as low-irritation, but individual sensitivity may still be reported in sensitive profiles. Patch testing is a measured approach.
A sensitivity advisory is not an instruction for use; where individual health circumstances, pregnancy or known sensitivities are involved, discussing the decision with your doctor may be a more contextual approach.
Common Misconceptions
Frequently Confused Points
Common Belief
As a highly efficient UVB filter, it provides sufficient protection alone.
A More Contextual Reading
Uvinul T 150 works only in UVB. Broad-spectrum coverage requires a complementary UVA filter; high UVB efficiency does not include UVA protection.
Common Belief
If used at a low dose, its protection must be weak.
A More Contextual Reading
High molar absorption can provide a strong UVB contribution at low concentrations. Assuming direct proportionality between dose and protective strength is misleading.
Common Belief
A newer-generation UVB filter is always better than older UVB filters.
A More Contextual Reading
It offers efficiency and photostability advantages, but 'always better' depends on context. The complete formula and protection balance matter.
