Fotoiniciadores | Migra\u00e7\u00e3o e toxicidade<\/strong><\/h1>\n

Ol\u00e1 a todos! Sou uma funcion\u00e1ria estrela da CHROM\u00c9CLAIR<\/a>, uma marca de esmalte em gel sem hema<\/u><\/a>Hoje, organizarei algumas informa\u00e7\u00f5es sobre a migra\u00e7\u00e3o e a toxicidade dos fotoiniciadores, esperando que sejam \u00fateis para voc\u00ea.<\/p>\n

O peso molecular dos fotoiniciadores normalmente varia entre 100 e 300. Por exemplo, o 1173 tem um peso molecular de 164,2, o TPO tem 348,4 e o 819 tem 418,5, todos classificados como compostos org\u00e2nicos de baixo peso molecular.<\/p>\n

Sob exposi\u00e7\u00e3o incompleta \u00e0 luz, essas mol\u00e9culas fotoiniciadoras podem permanecer no material curado, formando subst\u00e2ncias de migra\u00e7\u00e3o em potencial. Al\u00e9m disso, a gera\u00e7\u00e3o de radicais livres por fotoiniciadores \u00e9 obtida predominantemente por meio de rea\u00e7\u00f5es de clivagem. Esses radicais livres podem formar compostos de menor peso molecular ap\u00f3s a extin\u00e7\u00e3o final.<\/p>\n

Esses produtos de mol\u00e9culas pequenas n\u00e3o apenas contribuem para as preocupa\u00e7\u00f5es com a migra\u00e7\u00e3o, mas tamb\u00e9m podem gerar subst\u00e2ncias t\u00f3xicas. Tanto os fotoiniciadores residuais quanto as pequenas mol\u00e9culas produzidas durante as rea\u00e7\u00f5es apresentam riscos potenciais de migra\u00e7\u00e3o em produtos fotopolimerizados, o que pode afetar negativamente os usu\u00e1rios.<\/p>\n

The most significant incident occurred in 2005 when the photoinitiator ITX<\/a> was detected in Nestl\u00e9 infant formula in Italy. Globally, the European Union maintains the strongest focus on the health impacts of chemicals and enforces the most stringent regulations.<\/p>\n

Classifica\u00e7\u00e3o toxicol\u00f3gica e restri\u00e7\u00f5es ao uso de TPO<\/strong><\/h3>\n

With the widespread use of the fotoiniciador TPO<\/a>, regulatory oversight has intensified. Under the EU’s CLP (Classification, Labelling, and Packaging) Regulation, TPO was initially classified as a Category 2 (H361) reproductive toxicant, meaning \u201csuspected human reproductive toxicant, but the available evidence is not sufficient to conclusively classify it as Category 1.\u201d<\/p>\n

TPO (MAPO)<\/strong><\/h3>\n

Em junho de 2020, a Su\u00e9cia, um pa\u00eds n\u00f3rdico, prop\u00f4s revisar a classifica\u00e7\u00e3o para a Categoria 1B (H360DF) e adicion\u00e1-la como irritante para a pele (H317). A categoria 1B denota \"t\u00f3xico presumido para a reprodu\u00e7\u00e3o humana\", uma conclus\u00e3o baseada em evid\u00eancias substanciais de estudos com animais.<\/p>\n

\"\"O processo de harmoniza\u00e7\u00e3o de classifica\u00e7\u00e3o e rotulagem (CLH) da UE<\/strong><\/h3>\n

Os regulamentos tamb\u00e9m categorizam os t\u00f3xicos reprodutivos na Classe 1, que \u00e9 subdividida em 1A e 1B. 1A denota \"sabidamente t\u00f3xico para a reprodu\u00e7\u00e3o em seres humanos\", com base em evid\u00eancias substanciais em seres humanos, enquanto 1B denota \"presumivelmente t\u00f3xico para a reprodu\u00e7\u00e3o em seres humanos\", com base em evid\u00eancias substanciais de testes em animais. As subst\u00e2ncias da Categoria 1A s\u00e3o proibidas, enquanto as da Categoria 1B provavelmente ser\u00e3o proibidas ou restringidas. Anteriormente, a Su\u00e9cia, um pa\u00eds n\u00f3rdico, tamb\u00e9m prop\u00f4s modificar a classifica\u00e7\u00e3o para 1B (H360DF) e acrescent\u00e1-la como irritante para a pele (H317).<\/p>\n

No outono de 2021, o Comit\u00ea de Avalia\u00e7\u00e3o de Risco (RAC) da UE concordou em atualizar a classifica\u00e7\u00e3o do TPO. A Comiss\u00e3o Europeia (CE) est\u00e1 atualmente analisando essa classifica\u00e7\u00e3o, um processo que deve levar de 0,5 a 1,5 anos, de acordo com os regulamentos. Se aprovada pela CE, essa classifica\u00e7\u00e3o ser\u00e1 adicionada ao Anexo VI do Regulamento CLP da UE por meio de um ATP e se tornar\u00e1 juridicamente vinculativa. Em janeiro de 2023, a Su\u00e9cia anunciou sua inten\u00e7\u00e3o de propor a inclus\u00e3o do TPO na Lista de Candidatos a SVHC (Subst\u00e2ncias de Preocupa\u00e7\u00e3o Muito Alta).<\/p>\n

De acordo com o site da ECHA, o TPO foi adicionado \u00e0 Lista de Subst\u00e2ncias Candidatas de Preocupa\u00e7\u00e3o Muito Alta para Autoriza\u00e7\u00e3o em 14 de junho de 2023. Isso significa que o TPO agora est\u00e1 proibido ou restrito em muitas aplica\u00e7\u00f5es, como materiais de contato com alimentos.<\/p>\n

Op\u00e7\u00f5es alternativas de TPO<\/strong><\/h3>\n

Entre os fotoiniciadores de \u00f3xido de fosfina com boa absor\u00e7\u00e3o na banda UVA, duas outras alternativas comumente usadas al\u00e9m do TPO s\u00e3o o TPO-L e o 819 (BAPO). Entretanto, o TPO-L e o 819 podem substituir apenas parcialmente o TPO em determinadas aplica\u00e7\u00f5es e n\u00e3o podem substitu\u00ed-lo totalmente.<\/p>\n

\"\"O TPO-L possui uma estrutura semelhante \u00e0 do TPO, mas um anel de benzeno em sua mol\u00e9cula \u00e9 substitu\u00eddo por um grupo etoxi, resultando em menor toxicidade. Entretanto, o TPO-L apresenta uma efici\u00eancia de inicia\u00e7\u00e3o significativamente menor em compara\u00e7\u00e3o com o TPO.<\/p>\n

Outro fotoiniciador de \u00f3xido de fosfina \u00e9 o 819 (BABO), que pode ser visto como TPO com um anel de benzeno substitu\u00eddo por um grupo 2,4,6-trimetilbenzoil, possuindo efetivamente dois grupos 2,4,6-trimetilbenzoil. Embora o 819 apresente maior efici\u00eancia de inicia\u00e7\u00e3o do que o TPO, ele sofre de graves problemas de amarelamento, o que o torna inadequado para aplica\u00e7\u00f5es com requisitos de cor.<\/p>\n

O surgimento do TMO: a substitui\u00e7\u00e3o definitiva do TPO<\/strong><\/h3>\n

Nesse contexto, o advento do novo fotoiniciador TMO resolve fundamentalmente todos os desafios anteriormente associados ao TPO.<\/p>\n

TMO<\/strong><\/h3>\n

TMO, totalmente conhecido como (2,4,6-trimetilbenzoil)bis(p-tolil)\u00f3xido de fosfina, CAS 270586-78-2. Estruturalmente, o TMO introduz um grupo metil em cada um dos dois an\u00e9is de benzeno baseados no TPO, reduzindo significativamente a biotoxicidade do TPO. Os resultados experimentais indicam que o TMO apresenta uma efici\u00eancia de inicia\u00e7\u00e3o ligeiramente superior \u00e0 do TPO, al\u00e9m de n\u00e3o amarelar e apresentar menor migra\u00e7\u00e3o.<\/p>\n

Esse fotoiniciador \u00e9 utilizado em formula\u00e7\u00f5es de revestimento, oferecendo excelente solubilidade com olig\u00f4meros e diluentes reativos, al\u00e9m de ser isento de benzeno. O TMO \u00e9 adequado para a cura UV r\u00e1pida de revestimentos, tintas e adesivos de alta qualidade em v\u00e1rios substratos. Apresenta-se como um p\u00f3 cristalino amarelo-claro com um odor arom\u00e1tico caracter\u00edstico, \u00e9 est\u00e1vel, n\u00e3o se decomp\u00f5e facilmente em temperatura ambiente e \u00e9 sol\u00favel em v\u00e1rios solventes org\u00e2nicos.<\/p>\n

A rota de s\u00edntese do TMO \u00e9 considerada ecologicamente correta, produzindo produtos de alta pureza com alto rendimento. Em termos de cin\u00e9tica de fotopolimeriza\u00e7\u00e3o, o TMO demonstra um desempenho excepcional, exibindo propriedades superiores de absor\u00e7\u00e3o de luz, atividade de fotopolimeriza\u00e7\u00e3o e penetra\u00e7\u00e3o de cura profunda em compara\u00e7\u00e3o com os fotoiniciadores TPO tradicionais. Quando misturado com 1-hidroxiciclohexilbenzofenona (184), o TMO aumenta a fotossensibilidade e as caracter\u00edsticas de cura profunda.<\/p>\n

\"\"Curva de taxa de convers\u00e3o de liga\u00e7\u00e3o dupla de TMO e TPO iniciando TMPTA<\/strong><\/h3>\n

O TMO servir\u00e1 como um substituto ideal para o TPO e j\u00e1 alcan\u00e7ou a produ\u00e7\u00e3o em massa. Al\u00e9m disso, o TMO obteve o certificado de registro REACH da UE, permitindo sua venda na Europa - a regi\u00e3o com as regulamenta\u00e7\u00f5es qu\u00edmicas mais rigorosas.<\/p>\n

O fotoiniciador TMO foi testado para uso em tintas de impress\u00e3o e adesivos em superf\u00edcies de madeira, metal, pl\u00e1stico, papel e fibra \u00f3ptica. Apresenta excelente solubilidade em formula\u00e7\u00f5es UV comuns (por exemplo, acrilato, sistemas de poli\u00e9ster insaturado). Pode ser usado sozinho ou misturado com outros fotoiniciadores.<\/p>\n

A s\u00edntese do iniciador de TMO \u00e9 obtida usando \u00f3xido de di(p-tolil)fosfina e cloreto de 2,4,6-trimetilbenzoil como mat\u00e9rias-primas. Esse m\u00e9todo de s\u00edntese \u00e9 ecologicamente correto, eficiente e produz um produto de alta pureza com excelente rendimento. Testando suas propriedades fotof\u00edsicas e qu\u00edmicas, aplicando-o a sistemas de tinta, estudando sua cin\u00e9tica de fotopolimeriza\u00e7\u00e3o, estabelecendo um modelo cin\u00e9tico de cura e comparando-o com o \u00f3xido de 2,4,6-trimetilbenzoil-difenilfosfina (TPO), os resultados indicam que o TMO apresenta propriedades superiores de absor\u00e7\u00e3o de luz, atividade de fotopolimeriza\u00e7\u00e3o e desempenho de cura profunda em compara\u00e7\u00e3o com o TPO. Al\u00e9m disso, a co-formula\u00e7\u00e3o de TMO com 1-hidroxiciclohexilbenzofenona (184) aumenta a fotossensibilidade e as caracter\u00edsticas de cura profunda do TMO.<\/p>\n

Hoje, vou organizar algumas informa\u00e7\u00f5es sobre a migra\u00e7\u00e3o e a toxicidade dos fotoiniciadores, esperando que sejam \u00fateis para voc\u00eas. O peso molecular dos fotoiniciadores normalmente varia entre 100 e 300.

I'm a star employee at CHROM\u00c9CLAIR, a brand of hema free gel polish.Today, I'll organize some information about the migration and toxicity of photoinitiators, hoping it will be helpful to you.The molecular weight of photoinitiators typically ranges between 100 and 300. For example, 1173 has a molecular weight of 164.2, TPO has 348.4, and 819 has 418.5, all classified as low-molecular-weight organic compounds.Under incomplete light exposure, these photoinitiator molecules may remain in the cured material, forming potential migration substances. Furthermore, the generation of free radicals by photoinitiators is predominantly achieved through cleavage reactions. These free radicals may form lower molecular weight compounds upon final quenching.These small-molecule products not only contribute to migration concerns but may also generate toxic substances. Both residual photoinitiators and the small molecules produced during reactions pose potential migration risks in light-cured products, potentially adversely affecting users.The most significant incident occurred in 2005 when the photoinitiator ITX was detected in Nestl\u00e9 infant formula in Italy. Globally, the European Union maintains the strongest focus on the health impacts of chemicals and enforces the most stringent regulations.","og_url":"https:\/\/changhongchemical.com\/pt\/9088-2\/","og_site_name":"Changhong Chemical","article_published_time":"2025-10-28T08:52:15+00:00","article_modified_time":"2026-04-27T11:16:05+00:00","og_image":[{"width":3462,"height":2084,"url":"https:\/\/changhongchemical.com\/wp-content\/uploads\/2025\/10\/1-8.webp","type":"image\/webp"}],"author":"Changhong Chemical","twitter_card":"summary_large_image","twitter_misc":{"Escrito por":"Changhong Chemical","Est. tempo de leitura":"6 minutos"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/changhongchemical.com\/9088-2\/#article","isPartOf":{"@id":"https:\/\/changhongchemical.com\/9088-2\/"},"author":{"name":"Changhong Chemical","@id":"https:\/\/changhongchemical.com\/#\/schema\/person\/2a9593ff69d6db8f8ca0567ca3ed6b5d"},"headline":"Photoinitiators | Migration and Toxicity","datePublished":"2025-10-28T08:52:15+00:00","dateModified":"2026-04-27T11:16:05+00:00","mainEntityOfPage":{"@id":"https:\/\/changhongchemical.com\/9088-2\/"},"wordCount":1055,"publisher":{"@id":"https:\/\/changhongchemical.com\/#organization"},"image":{"@id":"https:\/\/changhongchemical.com\/9088-2\/#primaryimage"},"thumbnailUrl":"https:\/\/changhongchemical.com\/wp-content\/uploads\/2025\/10\/1-8.webp","articleSection":["Gel Polish","Photoinitiator"],"inLanguage":"pt-BR"},{"@type":"WebPage","@id":"https:\/\/changhongchemical.com\/9088-2\/","url":"https:\/\/changhongchemical.com\/9088-2\/","name":"Fotoiniciadores - Migra\u00e7\u00e3o e toxicidade - Changhong Chemical","isPartOf":{"@id":"https:\/\/changhongchemical.com\/#website"},"primaryImageOfPage":{"@id":"https:\/\/changhongchemical.com\/9088-2\/#primaryimage"},"image":{"@id":"https:\/\/changhongchemical.com\/9088-2\/#primaryimage"},"thumbnailUrl":"https:\/\/changhongchemical.com\/wp-content\/uploads\/2025\/10\/1-8.webp","datePublished":"2025-10-28T08:52:15+00:00","dateModified":"2026-04-27T11:16:05+00:00","description":"Ol\u00e1, pessoal! Hoje, vou organizar algumas informa\u00e7\u00f5es sobre a migra\u00e7\u00e3o e a toxicidade dos fotoiniciadores, esperando que sejam \u00fateis para voc\u00eas. O peso molecular dos fotoiniciadores normalmente varia entre 100 e 300. Por exemplo, o 1173 tem um peso molecular de 164,2, o TPO tem 348,4 e o 819 tem 418,5, todos classificados como compostos org\u00e2nicos de baixo peso molecular. Sob exposi\u00e7\u00e3o incompleta \u00e0 luz, essas mol\u00e9culas de fotoiniciador podem permanecer no material curado, formando subst\u00e2ncias com potencial de migra\u00e7\u00e3o. Al\u00e9m disso, a gera\u00e7\u00e3o de radicais livres por fotoiniciadores \u00e9 predominantemente obtida por meio de rea\u00e7\u00f5es de clivagem. Esses radicais livres podem formar compostos de menor peso molecular ap\u00f3s a extin\u00e7\u00e3o final. Esses produtos de mol\u00e9culas pequenas n\u00e3o s\u00f3 contribuem para as preocupa\u00e7\u00f5es com a migra\u00e7\u00e3o, mas tamb\u00e9m podem gerar subst\u00e2ncias t\u00f3xicas.
