Key Differences Between Dyes and Pigments Explained
Dyes and pigments are the main types of colorants widely used for coloring different materials they are applied. The difference between dyes and pigments is their solubility: dyes are soluble in water and pigments are insoluble and are dispersed in a binder or medium. In this blog, we will discuss what is the difference between dyes and pigments.
Dyes and pigments behave differently because of their particle size, making them distinct. Both dyes and pigments are used as colorants in various industrial applications, ranging from food, drugs, and cosmetics to home and personal care products.
If you are wondering what are dyes and pigments and what differentiates them from each other, then you have come to the right place. Continue reading this blog further to get a better understanding of the difference between dyes and pigments.
Basic Understanding of Dyes?
Many of us often wonder what are dyes and how they are produced. Dyes are colored substances used to provide color to materials they are applied. Dyes provide more vibrant, brighter colors that offer greater stability and durability and don’t fade away over time.
Synthetic dyes and Natural Dyes are two main types of dyes widely used for coloring different materials. When it comes to the comparison between natural dyes vs synthetic dyes, both have different strengths, areas of application, and chemical properties.
Synthetic dyes are derived from petrochemicals and coal tar under a well-crafted laboratory or state-of-the-art manufacturing facility. On the other hand, natural dyes are obtained from natural sources, such as plants, trees, green vegetables, beetroots, animals, minerals, etc.
However, choosing the right food colors or dyes is essential for your business when it comes to using them in different applications, such as food and beverage, pharmaceuticals, and cosmetics. Furthermore, dyes can be soluble easily in the material they are used and can be produced from natural sources as well as synthesized processes through chemical reactions.
What are pigments?
Pigments refer to colored substances that are mainly used to reflect and absorb light on the surface of the material, in order to impart color to other substances. A pigment creates a color when it interacts or comes in contact with light.
The key difference between dyes and pigments is that pigments are not soluble in the material they are applied, while dyes are soluble in the material. Pigments are broadly produced from natural sources, such as plants, minerals, and animals, and through chemical reactions with a synthesized process.
Difference between dyes and pigments
Dyes and pigments are different in many ways and both function differently from the other one. The following are the key differences between dyes and pigments you should know about:
| Properties | Dyes | Pigments |
| Solubility | Soluble in water and most solvent liquids. | Insoluble in water and most solvent liquids. |
| Light-fastness | They have greater resistance to light. | Less resistance to light. |
| Bonding | Dyes are easily soluble in aqueous solutions. | Need a medium or binder to be dissolved in aqueous solutions. |
| Particle Size | Smaller in composition size. | Larger in composition size. |
| Stability | Poor stability than pigments. | Greater stability than dyes. |
| Brightness | Dyes are more vibrant and brighter. | They are less bright than dyes. |
| Transparency | Dyes show more transparency than pigments. | Pigments are more opaque than dyes. |
| Method of Application | Generally, dyes penetrate a material and color it from the inside. | Pigments reflect and absorb the light to cause color to a material. |
| Chemical Composition | Dyes are organic compounds. | Pigments are inorganic compounds. |
| Cost | Dyes are more expensive than pigments. | Pigments are less expensive. |
Conclusion
Both dyes and pigments are widely used substances or coloring materials in a variety of applications in different industry verticals, including food, drugs, and cosmetics.
