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](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory.md) matrix and monitoring their effectiveness as UV stabilizers. This approach allows for monitoring their stability, anticipating their consumption during [ageing](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/laboratory-material-testing/filab-accelerated-ageing-test-laboratory/), 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: Durability guarantee - 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. Mastering quality and performance - Maintain the balance of the [additive](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives.md) 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. Regulatory compliance - 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. ### Our organic additive analysis services [Analysis of Irgafos 168 (CAS No. 31570-04-4)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-irgafos-168.md) [Analysis of Triphenyl phosphite (TPP) CAS No. 101-02-0](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-tpp-cas-01-02-0.md) [Analysis of DBP (dibutyl phthalate) CAS No. 84-74-2](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-dbp.md) [Analysis of TOTM (trimellitate) CAS No. 3319-31-1](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-totm.md) [Analysis of Irganox 1010 (CAS No. 6683-19-8), Irganox 1076 (CAS No. 2082-79-3), Irganox 3114 (CAS No. 27676-62-6)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-additives-irganox-1010-1076-3114.md) [Analysis of Chimassorb 944 (CAS No. 71878-19-8)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-chimassorb-944.md) [Analysis of BHT (butylated hydroxytoluene) CAS No. 128-37-0](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-bht-cas-128-37-0.md) ## FILAB meets your analysis needs Tinuvin 770 (CAS No. 52829-07-9), Tinuvin 622 (CAS No. 65447-77-0), Tinuvin 327 (CAS No. 3864-99-1), Tinuvin 328 (CAS No. 25973-55-1), Tinuvin P (CAS No. 2440-22-4) ### Our technical resources for the analysis of Tinuvin [### HPLC To separate and quantify Tinuvin from the other ingredients in the formula](https://filab.fr/en/our-technical-resources/laboratory-analysis-uplc.md) [### GC-MS To identify and quantify Tinuvin](https://filab.fr/en/our-technical-resources/laboratory-analysis-gcms.md) [### LC-MSMS To detect and quantify traces of Tinuvin or its degradation products](https://filab.fr/en/our-technical-resources/altis-lc-msms-analysis.md) [### FTIR For qualitative analysis on samples of pure Tinuvin or in the raw material](https://filab.fr/en/our-technical-resources/laboratory-analysis-ftir-spectroscopy.md) ## Why choose FILAB for organic additive analysis: Tinuvin For over ten years, the FILAB laboratory has developed extensive expertise in [chemical analysis](https://filab.fr/en/our-services/our-analysis-services/chemical-analysis-laboratory.md).

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. What types of Tinuvin are involved? - 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. What analytical techniques are used? 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. Why is it important to track their degradation products? 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. Which sectors are affected by this type of analysis? The plastics, medical, automotive, construction, coatings, packaging film and all outdoor application industries require precise control of UV stabilizers. When should a Tinuvin analysis be performed? 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. What does a complete analysis validate? 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.
