Overall Introduction of Organic Pigment

What is pigment and dyes?

1.Pigment Definition

1.1 International Definition

Pigments are colored, black, white or fluorescent particulate organic or inorganic solids which usually are insoluble in, and essentially physically and chemically unaffected by, the vehicle or substrate in which they are incorporated. They alter appearance by selective absorption and by scattering of light. Pigments are usually dispersed in vehicles or substrates for application, as in the manufacture or inks, paints, plastics or other polymeric materials. Pigments retain a crystal or particulate structure throughout the coloration process.-defined By CPMA (The Color Pigments Manufacturers Association, Inc.),

Dyes are intensely colored or fluorescent organic substances only, which impart color to a substrate by selective absorption of light. They are soluble and go through an application process which, at least temporarily, destroys any crystal structure by absorption, solution, and mechanical retention, or by ionic or covalent chemical bonds.—defined By ETAD (The Ecological and Toxicological Association of Dyes and Organic Pigment Manufacturers). Both are of categories of colorant which definition is a substance used for coloring a material, sometimes also called coloration matter or coloring matter

1.2 Simplify Definition

Pigment refers to a class of organic matter that insoluble in water, not soluble in the use of media, but has been highly dispersed state of particles so that the colored matter is colored; Dye is dissolved in water or other solvent colorant, pigment and dyes solubility in water, as followspigment-and-dyes-solubility-in-water-baoxuchemical-info@additivesforpolymer.com

1.3 Pigment Synonyms

When we talk about pigments, there are several synonyms of pigment might be mentioned, such as color pigment, colorant, coloration, coloring agent.

Pigment Classification

2.1. Classified by Chemical Structure

The pigment can be classified into organic pigments, inorganic pigments, organic pigments which can be divided into azo pigments and non-azo pigments, as picture 2 belowpigment-classification-baoxu chemical info@additivesforpolymer.com

[accordion-item title=”Difference Between Organic and Inorganic Pigments” state=closed]

Compared with organic pigments, inorganic pigments have lower cost, simple production process and higher yield than organic pigments. Also excellent light resistance, heat resistance, and weatherability. Inorganic pigment is suitable for architectural coatings, glass, ceramics, rubber, and plastics coloring.

Compared with inorganic pigments, organic pigments are widely used in the fields of ink, paint, and plastic, due to a wide range of colors, bright colors, and bright hue. A very high tinting power is formed. Organic pigments can be prepared through the deep processing to meet different application requirements (such as high tinting strength, high transparency, high mobility, etc.) special commodity formulations, among them, high-performance. Organic pigments are with excellent light resistance, heat resistance, solvent resistance and other applications performance, in line with the high-grade inks, coatings and plastics areas coloring needs.

The global organic pigments market to grow at a CAGR of more than 3% to 3.5% between 2017 and 2021 main production areas includes China, India.we assume China pigment industry trends as follows
● concentration of organic pigment segment will increase;
● vendors getting lessen;
● profitability getting better.

Legislations And Regulations of Organic Pigment

Legislation and regulations for pigments are primarily related to food packaging, consumer goods and toys. Two general principles must be satisfied;

1. The pigment producer has to assure his customer that the pigment is toxicological of no concern.

2. The manufacturer of the pigmented articles must guarantee that the pigment neither migrates into food nor migrates from consumer goods or toys.

Main Legislation Concerning Organic Pigments

Food Packaging

Materials and articles intended to come into contact with foodstuff are generally regulated in the EU in the Framework Directive 89/109/EEC. Under this Directive Single Directives are released, such as for Plastic Material (90/128/EEC), Cellulose Films (83/229/EEC), Elastomers and Rubber (93/11/EEC) and others. Directive 89/109/EEC generally requires that the constituents of all food contact material do not transfer to the foodstuff in quantities which could endanger human health.

European Union AP (89) 1 (1989)

Council of Europe Resolution AP (89) 1 (1989)

  • The maximum threshold limits of metals or metal ions soluble in 0,1 m hydrochloric acid is as follows: Metal ppm Metal ppm As 100 Hg 50 Ba 100 Pb 100 Cd 100 Sb 500 Cr 1000 Se 100.
  • The trace amount of primary aromatic amines, which are soluble in 1 m hydrochloric acid, must be lower than 500 ppm (expressed as aniline). ETAD*) developed a testing method for aromatic amines.
  • The threshold limit for aromatic amino sulfonic acids expressed as aniline sulfonic acid, must be below 500 ppm.
  • For benzidine, 2-naphthylamine and 4-aminodiphenyl the threshold limit is 10 ppm.
  • The trace amount of polychlorinated biphenyls (PCB) should not exceed 25 mg/kg.

EU 94/62/EEC

The concentration limits of lead, Cadmium, Mercury, and Chromium (VI) in packaging material or components of packaging material are not allowed to exceed 100 ppm (cumulative). This is in force since June 30, 1994.

The Scientific Committee for Food (SCF) lays down for toxicological evaluation of food contact substances three levels of toxicological tests dependent on the amount of migration (mg/kg food simulant): Level 1: < 0.05; level 2: 0.05-5; level 3: >5.

USA CONEG Regulation

nearly same as in 94/62/EEC (see above).

Other Countries

Several countries have released identical or similar regulations as the European Regulation AP (89)1 regarding the threshold limits for metals, aromatic amines, aromatic amino sulfonic acids and PCB.

Toys

On a national basis, Toys require compliance of limits for the same impurities as outlined under food packaging. In particular trace, metal amounts have to be considered as well as threshold limits for aromatic amines, soluble in 0,07 m hydrochloric acid. The trace amount of cancerogenic amine should depend on the various countries, not exceed 5 or 10 ppm.

European Union EN 71-3 (1994)

European Toy-Norm EN 71-3 (1994), with different threshold limit levels.

USA FDA

comply with FDA paragraphs 21 CFR 178, 3297 and apply for FCN(Food Contact Notifications)

Other Substances Related

Polychlorobiphenyls (PCB)

Strict legal limits have been defined in some countries (for instance in the USA, and also throughout the European Union) because of the persistency and the wide distribution of these compounds. These regulations have primarily been issued to protect the environment, less because of a direct hazard to humans.  Legislation 592 PCB traces may be found in two groups of organic pigments, namely in – azo pigments derived from chloroaniline or dichloro or tetrachlorodiamino- diphenyl, which may undergo various side reactions that produce traces of PCB, – pigments which are manufactured in the presence of dichlorobenzene or trichlorobenzene as a solvent. In this case, PCB may be formed through radical reactions.

Polychlorinated Dioxins/Furans (“Dioxins”)

Similar conditions as for the formation of PCB’s might also lead to the formation of small trace amounts of dioxins. A German Hazardous Substances Ordinance (Chemikalien-Verbotsverordnung) prohibits to place products on the market for which very low limits of dioxin traces are exceeded. Regulated dioxins are those who at least are tetrachloro (or promo) substituted in 2,3,7,8-position Phthalates
