What is the difference between natural colorants and synthetic colorants?

As we know,the application fields of pigment are very wide, mainly covering food, cosmetics, textiles, medicine and industrial fields.

· In the field of food, colorants are generally used to increase or restore the color of food, make food more attractive to increase people’s appetite, and are used to identify categories. For example, the natural colorants curcumin is used in yellow foods, beet red is used in juice or candy, and spirulina blue is used in ice cream or drinks. synthetic colorants carmine is used in drinks and lemon yellow is used in pastries and snacks.

· In the field of cosmetics, it is generally used to enhance the color of cosmetics, thereby improving the beauty and color rendering of products. For example, saffron yellow is used in lipstick, and rouge orange is used in blush and eyeshadow; synthetic colorants are used to adjust the color of lipstick, nail polish and eye shadow to meet the needs of different users.

· In the textile field, colorants are mainly used in the dyeing of clothing and furniture textiles to make the bright colorants of materials more durable. For example, the natural colorants indigo is used for denim dyeing, and gardenia yellow is used for traditional fabrics; the synthetic colorants are used for dyeing cotton, nylon and polyester.

· In the field of medicine, colorants are generally used in the appearance design of drugs and capsules to facilitate the differentiation of drugs or to improve the acceptance of drugs. For example, chlorophyll, a natural colorants, is used in the green coating of pills, and beta-carotene is used in orange capsules; synthetic colorants are used for color-marked or easy identification and branding.

· In the industrial field, it is generally used for coloring industrial products such as paints and plastic printing inks, such as natural colorants for environmentally friendly coatings and biodegradable packaging materials; synthetic colorants are widely used in light – and heat-resistant coatings, plastic products and printing equipment.

The main differences between natural colorants and synthetic colorants are their source, composition, function and health effects.

Source • Natural colorants, extracted from plants, animals or minerals. For example, carotene (from carrots), anthocyanins (from blueberries), and curcumin (from turmeric). • Synthetic colorants, synthetic by chemical reaction, mostly petroleum or coal tar derivatives. For example, carmine, lemon yellow, etc.

Ingredients • Natural colorants,Usually complex organic compounds containing a variety of natural ingredients that may accompany antioxidants or other nutrients. • Synthetic colorants, single composition, usually pure compounds, easier to achieve color stability and standardization.

Security • Natural colorants, Generally considered safer as they come from nature, but can also cause problems due to impurities or allergic reactions. • Synthetic colors, Some are considered to be possible health risks, such as allergies, hyperactivity in children, or long-term consumption of potential harm to the human body, so the use of strictly limited.

Color expression • Natural pigment, the color is soft, the stability is poor, easy to be affected by light, temperature and pH value, easy to fade. • Synthetic pigment, bright color, variety, strong stability, can meet a variety of processing needs.

Advantages of natural colorants

Health properties: Natural colorants often contain antioxidant components, such as carotenoids, anthocyanins, etc., which may be beneficial to health. Environmental protection: The production of natural colorants has less pollution to the environment. Consumer preference: With the improvement of health awareness, consumers are more inclined to buy foods labeled “natural” or “without artificial colors”.
