Pigment | Synthetic, Organic, Inorganic (1)

pigment, any of a group of compounds that are intensely coloured and are used to colour other materials.

Pigments are insoluble and are applied not as solutions but as finely ground solid particles mixed with a liquid. In general, the same pigments are employed in oil- and water-based paints, printing inks, and plastics. Pigments may be organic (i.e., contain carbon) or inorganic. The majority of inorganic pigments are brighter and last longer than organic ones. Organic pigments made from natural sources have been used for centuries, but most pigments used today are either inorganic or synthetic organic ones. Synthetic organic pigments are derived from coal tars and other petrochemicals. Inorganic pigments are made by relatively simple chemical reactions—notably oxidation—or are found naturally as earths.

The Origins of Colors, Pigments, and Dyes

Inorganic pigments include white opaque pigments used to provide opacity and to lighten other colours. The most important member of the class is titanium dioxide. White extender pigments are added to paints to lower their cost or improve their properties. This class includes calcium carbonate, calcium sulfate, diatomaceous silica (the remains of marine organisms), and china clays. Black pigments are primarily created from particles of carbon. Carbon black, for example, is used to give black colour to printing inks. Iron-oxide earth pigments yield ochres (yellow-browns), siennas (orange-browns), and umbers (browns). Certain compounds of chromium are used to provide chrome yellows, oranges, and greens, while various compounds of cadmium yield brilliant yellows, oranges, and reds. Iron, or Prussian, blue and ultramarine blue are the most widely used blue pigments and are both inorganic in origin.

For the most part, organic pigments are presently synthesized from aromatic hydrocarbons. These are compounds containing structures of carbon atoms with hydrogen atoms attached that are formed in closed rings. Organic pigments include azo pigments, which contain a nitrogen group; they account for most of the organic red, orange, and yellow pigments. Copper phthalocyanines provide brilliant, strong blues and greens that are unusually colourfast for organic colours. Some pigments, such as fluorescent ones, are simply dyes that have been rendered insoluble by chemical reaction.

FAQs

Are pigments organic or inorganic? ›

Pigments may be organic or inorganic. The majority of inorganic pigments are brighter and last longer than organic ones. Organic pigments made from natural sources have been used for centuries, but most pigments used today are either inorganic or synthetic organic ones.

Can you mix organic and inorganic pigments? ›

The Organic Hybrid Line and the Inorganic Mineral Line. Depending on your client's skin type and desired results you can select the best option for them, and all Hanafy pigments from both lines can be mixed for beautiful, bespoke results.

Are brow daddy pigments inorganic? ›

Our brand-new, 100% inorganic pigment line is a game-changer for clients seeking super natural results that fade gradually over time, allowing for flexible touch-ups and the option to change brow shape or color.

Are Tina Davies pigments organic or inorganic? ›

All Perma Blend pigments, including Tina Davies I ❤️INK, are a blend of both organic and inorganic pigments and are identified as a hybrid pigment line. Hybrid pigment formulations have a blend of both organic and inorganic pigment particles.

What is organic vs inorganic? ›

Organic compounds are derived from or produced by living organisms and have carbon-hydrogen covalent bonds. Inorganic compounds are derived from nonliving components, and generally have ionic bonds, lack carbon-hydrogen bonds, and rarely, if ever, contain any carbon atoms.

Are ever after pigments organic or inorganic? ›

Is Ever After organic or inorganic? Our pigments contain both inorganics and synthetically modified organics, which offers easy implantation, vibrant colors, high lightfastness and longevity, and stable consistency. Is Ever After Vegan? Yes.

What is the most common inorganic pigment? ›

Titanium dioxide (TiO2) is now the most commonly used white synthetic inorganic pigment. Iron oxides derived from natural sources (ores like hematite, magnetite, siderite, etc.) are the most widely used earth pigments.

Do organic pigments fade? ›

Organic-based pigments are also more prone to fading with cooler blue or grey tones over time, whereas the iron oxides within inorganics can lead to brows fading to warmer, red tones.

What are the disadvantages of organic pigments? ›

Varying lightfastness: There are many different varieties of organic pigments, but most of them tend to hold up poorly when exposed to light. While some can resist light and heat exposure well, many will fade over time.

Is ultramarine blue pigment organic or inorganic? ›

This is because Ultramarine is an inorganic pigment. Organic pigments often have an adverse affect on the dimensional stability of polyolefin mouldings. Ultramarine has many positive attributes that make it ideal for most plastics applications, but there are some potential problems to be aware of.

Are Phibrows pigments organic? ›

For Phibrows, it's a mixture of synthetic and organic pigment components so they last 1 – 2 years. They are also neutral meaning not too cold and not warm. They best represent the natural eyebrow color, and for microblading it's really best to stick to your client's natural hair color, so they are really perfect.

Are Monica Ivani pigments organic? ›

Monica Ivani by Li Pigments are In-organic, made from high quality synthetic iron oxides. They are pre modified, meaning they do not generally need to have any warmth added to them, but you may consider using something like Li Pigments Grey vanish or Li Pigments Ungrey to warm for certain skin types.

Are KB Pro pigments organic or inorganic? ›

Developed using a higher standard organic and inorganic colorant, the formula has a water-based, creamy consistency that perfectly clings to the needle every treatment. The highly concentrated pigments ensure no splatter or pooling, and deliver fade-resistant, lasting colour.

How do you make inorganic pigments? ›

Many inorganic pigments are prepared by the mixing of two colorless or lightly colored solutions of inorganic chemicals to produce a highly colored, insoluble precipitate of the desired pigment.

Are mineral pigments organic? ›

Understanding Mineral and Modern Pigments for Painters

Paint companies and chemists divide color pigments, used for making paints, into two distinct categories: mineral (made from natural sources known as inorganics) and modern (made synthetically known as organics).

What is the classification of pigments? ›

Pigments are classified as inorganic and organic. Both pigment classes are insoluble in resins and therefore require high shear to become properly dispersed in a resin.

What is the difference between organic and inorganic tattoo pigments? ›

Organic pigments do not leave much room for error, and it can be easy to over-saturate if you are newer to cosmetic tattooing. Organic-based pigments are also more prone to fading with cooler blue or grey tones over time, whereas the iron oxides within inorganics can lead to brows fading to warmer, red tones.

Are dyes organic or inorganic? ›

Most dyes are organic compounds (i.e., they contain carbon), whereas pigments may be inorganic compounds (i.e., they do not contain carbon) or organic compounds. Pigments generally give brighter colours and may be dyes that are insoluble in the medium employed.
