Cochineal extract or carmine (E120) is a natural red colorant derived from the dried bodies of the female cochineal insect.

It is widely used to impart a pink, red, or purple hue to various food and beverage products, including yogurts, ice creams, confectionery, and fruit juices.

Although it is a natural additive, E120 is known to cause severe allergic reactions, including anaphylaxis, in some individuals. It is also not suitable for vegetarians or vegans due to its insect origin.

Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. Generally, it is sourced from ilmenite, rutile and anatase. It has a wide range of applications, including paint, sunscreen and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million metric tons. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and the oxide has been valued at $13.2 billion.

Citric acid is a natural organic acid found in citrus fruits such as lemons, oranges, and limes.

It is widely used in the food industry as a flavor enhancer, acidulant, and preservative due to its tart and refreshing taste.

Citric acid is safe for consumption when used in moderation and is considered a generally recognized as safe (GRAS) food additive by regulatory agencies worldwide.

Tragacanth is a natural gum obtained from the dried sap of several species of Middle Eastern legumes of the genus Astragalus, including A. adscendens, A. gummifer, A. brachycalyx, and A. tragacantha. Some of these species are known collectively under the common names "goat's thorn" and "locoweed". The gum is sometimes called Shiraz gum, shiraz, gum elect or gum dragon. The name derives from the Greek words tragos (meaning "goat") and akantha ("thorn"). Iran is the biggest producer of this gum. Gum tragacanth is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides obtained from sap that is drained from the root of the plant and dried. The gum seeps from the plant in twisted ribbons or flakes that can be powdered. It absorbs water to become a gel, which can be stirred into a paste. The major fractions are known as tragacanthin, highly water soluble as a mucilaginous colloid, and the chemically related bassorin, which is far less soluble but swells in water to form a gel. The gum is used in vegetable-tanned leatherworking as an edge slicking and burnishing compound, and is occasionally used as a stiffener in textiles. The gum has been used historically as a herbal remedy for such conditions as cough and diarrhea. As a mucilage or paste, it has been used as a topical treatment for burns. It is used in pharmaceuticals and foods as an emulsifier, thickener, stabilizer, and texturant additive (E number E413). It is the traditional binder used in the making of artists' pastels, as it does not adhere to itself the same way other gums (such as gum arabic) do when dry. Gum tragacanth is also used to make a paste used in floral sugarcraft to create lifelike flowers on wires used as decorations for cakes, which air-dries brittle and can take colorings. It enables users to get a very fine, delicate finish to their work. It has traditionally been used as an adhesive in the cigar-rolling process used to secure the cap or "flag" leaf to the finished cigar body.Gum tragacanth is less common in products than other, usually cheaper, gums, such as gum arabic or guar gum. Different gums tend to be interchangeable across many uses, and production of tragacanth is far outpaced by these for reasons of economy, trade, agriculture and history, while tragacanth is mostly produced in traditional locations. However, gums are used in varied circumstances and there are many situations where tragacanth is considered superior. Common substitutions are methyl cellulose, sometimes marketed as "substitute gum tragacanth" in the food industry, and gum karaya. Gum karaya, also called "Indian tragacanth" or simply "tragacanth", might be fully or partially substituted for what appears to be genuine tragacanth. Gum tragacanth is also used in incense-making as a binder to hold all the powdered herbs together. Its water solubility is ideal for ease of working and an even spread, and it is one of the stronger gums for holding particles in suspension. Only half as much is needed, compared to gum arabic or something similar.In Saudi Arabia, a mixture of hydrated Tragacanth and ground dried Ziziphus spina-christi is used as a natural hair shampoo that is believed to promote hair growth.

Glycerol (; also called glycerine or glycerin; see spelling differences) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in all lipids known as triglycerides. It is widely used in the food industry as a sweetener and humectant and in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.
