You would like to carry out the analysis of organic additives : Tinuvin 770, Tinuvin 622, Tinuvin 327, Tinuvin 328, Tinuvin P
In what context should a Tinuvin analysis be performed?
The analysis of Tinuvin 770, 622, 327, 328, and P, as well as the quantification of their degradation products, are essential for understanding their behavior within the polymer matrix and monitoring their effectiveness as UV stabilizers.
This approach allows for monitoring their stability, anticipating their consumption during ageing, and evaluating the overall evolution of the material exposed to light, UV radiation, or harsh environmental conditions.
The objective of this analytical strategy is threefold:
- Ensure long-term protection of materials against photodegradation by maintaining the effectiveness of the Tinuvin incorporated into the formulation.
- Prevent premature deterioration phenomena such as yellowing, breakage, loss of mechanical properties, or polymer embrittlement.
Maintain the balance of the additive system (antioxidants, HALS, UV absorbers, thermal stabilizers, etc.).
Prevent destabilization of the formulation by closely monitoring residual levels and derivatives resulting from Tinuvin degradation, particularly during prolonged exposure to UV radiation or heat.
- Strictly control the concentrations of Tinuvin and degradation byproducts, particularly in sectors where light stability is regulated (cosmetics, medical devices, packaging, outdoor applications).
- Ensure compliance with regulatory requirements related to UV resistance, material durability, and chemical safety according to the end use.
What is Tinuvin?
Tinuvin 770 (CAS No. 52829-07-9)
It is a HALS (Hindered Amine Light Stabilizer).
It protects polymers against light degradation by neutralizing free radicals formed by UV exposure. It is particularly effective in polyolefins, polyamides, and polyurethanes.
Tinuvin 622 (CAS No. 65447-77-0)
It is also a HALS stabilizer, but in copolymer form, which gives it better compatibility in plastic systems and low migration. It is widely used in films, fibers, and applications subject to prolonged UV exposure.
Tinuvin 327 (CAS No. 3864-99-1)
It is a benzotriazole-type UV absorber.
It absorbs UV energy and dissipates it harmlessly to the polymer structure, thus preventing yellowing, embrittlement, or loss of mechanical properties.
Tinuvin 328 (CAS No. 25973-55-1)
Another benzotriazole UV absorber, more effective in certain transparent polymers.
It offers excellent thermal stability and very good efficiency in optical applications, polyurethanes, engineering plastics, and certain coatings.
Tinuvin P (CAS No. 2440-22-4)
It is a traditional UV absorber of the benzophenone type.
It protects materials by limiting photodegradation, although it is less effective than more recent generations. It remains widely used in varnishes, coatings, films, and sensitive plastics.

FAQ
The analysis verifies the presence, concentration, and stability of UV stabilizers within the matrix. It is essential to guarantee the material's protection against photodegradation and to anticipate performance losses.
- Tinuvin 770 and 622: HALS stabilizers (radical scavengers).
- Tinuvin 327 and 328: benzotriazole UV absorbers.
- Tinuvin P: benzophenone UV absorber.
Their analysis allows for the precise identification of the additive family present and their potential state of degradation.
Quantification relies primarily on chromatography (LC-MS, GC-MS), enabling selective and sensitive detection. Complementary techniques such as spectroscopy (FTIR) or TGA can be used depending on the matrix and objectives.
Tinuvin compounds can degrade under the influence of light, heat, or oxygen. Monitoring these derivatives allows for the evaluation of actual stabilizer consumption, the diagnosis of photodegradation of the material, and the adjustment of the formulation if necessary.
The plastics, medical, automotive, construction, coatings, packaging film and all outdoor application industries require precise control of UV stabilizers.
It is recommended to analyze these additives during:
- formulation development,
- regular quality control,
- accelerated aging tests,
- issues such as yellowing, embrittlement, or loss of mechanical properties.
It allows us to confirm the quantity of additive present, its stability, its interaction with other additives, and the overall effectiveness of the UV stabilization system. It is a key tool for guaranteeing the durability and performance of the material.
