β-Ionone is a clear slightly yellow to yellow liquid with a characteristic violet-like odor, more fruity and woody than α-ionone. It’s soluble in ethanol, diethyl ester and dichloromethane, slightly soluble in water. The natural beta-ionone is found in many plants, such as violets. It is prepared by condensation of citral and acetone in dilute caustic soda solution and cycling with sulfuric acid or phosphoric acid.

Beta-ionone is mainly applied as an important raw material in pharmaceutical, especially for the production of vitamin A, vitamin E and carotene. Some recent researches demonstrate the anti-proliferative, anti-metastatic and apoptosis induction properties of beta-ionone in vitro and in vivo that can probably be used in cancer care or even treatment in the near future.

Cajeput oil is produced by steam distillation of fresh leaves and twigs of the cajeput tree (Melaleuca leucadendra).

It is widely used in food, pharmaceutical and as general household remedies for colds, throat irritation, pain, headache, etc.

Cajeput Oil Composition vs. Tea Tree Oil
Tea tree oils are extracted from Melaleuca alternifolia while cajeput is from Melaleuca Cajuputi or Melaleuca Leucadendra ( var. cajuputi).

Cajeput contains higher concentrations of 1,8 Cineole (Eucalyptol), limonene and alpha-Terpineol. Tea tree oil contains more Terpinen-4-ol and gamma-Terpinene. Therefore, cajeput has some properties similar to those found in Eucalyptus (from the Eucalyptol) and Lemon (from the limonene).

It can also be extracted from citronella essential oil, Mexican cypress, bourbon rose and other natural materials. It’s widely used in a variety of flower fragrance daily flavor and apple, sweet orange, peach, plum and other edible flavors.

Elemol, Alpha Elemol and Beta Elemol, is a kind yellow to brown yellow viscous liquid or crystal extracted from olive oil and citronella oil.

Eucalyptus Citriodora oil is colorless, light yellow or greenish-yellow liquid with a grass aroma like citronella aldehyde, mainly composed of citronella aldehyde (up to 65-95%), citronella alcohol, geraniol and its esters, pinene, eucalyptus, iso-menthol, sesquiterpene alcohol, guacanol, etc. it is obtained by steam distillation of the leaves and top branches of the myrtle plant lemon eucalyptus

Geranium oil is produced by steam distilling the pelargonium grave-olens plant’s flowers and leaves.

Geranium oil is considered nontoxic, nonirritant and generally non-sensitizing – and the therapeutic properties of it include being an antidepressant, an antiseptic and wound-healing.

Geranyl Butyrate is white or off-white oily liquid or powder obtained by direct esterification of geraniol and butyric acid in azeotropic state. It is a synthetic ester spice with a more elegant flavor than geranyl acetate and is mainly used as lavender, rose, acacia, lily of the valley, geranium and other fragrances blending spices.

Geranyl Formate is a colorless to pale yellow liquid and has the aroma of fresh leaves and roses and the bitter taste.

The esterification method is widely used in production. Using formic acid and geraniol as raw materials, esterification is carried out in the presence of anhydrous calcium chloride and obtained by neutralization, washing and drying.

Geranyl Formate can also be extracted from natural raw materials such as geranifolium oil and camellia oil.

Turpentine can be divided into gum turpentine, wood turpentine and sulphate turpentine in the light of sources of raw materials. Gum turpentine is extracted from pine resin by distillation.

Turpentine is colorless to pale yellow oily liquid containing various terpenes. The presence of double bonds and rings in the terpenes enables multiple reactions.

It is composed of terpenes, mainly the monoterpenes alpha-pinene and beta-pinene with lesser amounts of carene, camphene, dipentene, and terpinolene. It is sometimes colloquially known as turps.

It can be used in solvent and as a source of materials for organic synthesis, or as a source of raw materials in the synthesis of fragrant chemical compounds. It also can be used in medicinal elixir and cleaning products.

Helional is derivative of heliotropin. It appears yellow liquid.
