Raspberry ketone is a natural phenolic compound that is the primary aroma compound of red raspberries.

It can be extracted from the fruit, yielding about 1 to 4 mg per kg of raspberries.

Resin Emulsion is an aqueous, solvent free resin made from polymerized rosin

Rosmarinic acid is a naturally occurring polyphenolic compound widely found in various Lamiaceae plants such as rosemary, sage, mint, and basil. Chemically, it is an ester of caffeic acid and 3,4-dihydroxyphenyllactic acid. It is considered a natural, highly efficient, and well-stable antioxidant and a green food additive. It exhibits low toxicity and is generally considered safe. In terms of solubility, it is slightly soluble in water but readily soluble in alcohols and oils.

Research indicates that rosmarinic acid has a strong effect in scavenging free radicals, and its antioxidant activity is stronger than that of Vitamin E. It also possesses broad-spectrum antimicrobial, antiviral, anti-inflammatory, anti-tumour, anti-platelet aggregation, antithrombotic, antiangiogenic, and antipsychotic properties, as well as the function of fighting neurodegenerative diseases.

Star Anise Oil is a precious essential oil extracted from the natural star anise fruits and leaves. The core component of Star Anise Oil is trans-Anethole, typically present in high concentrations ranging from 80% to 90%. Additionally, it contains minor constituents such as Estragole, D-Limonene, Linalool, and alpha-Pinene.

It presents as a clear liquid with no colour or a light yellow hue, characterised by its distinctive liquorice or anise aroma.

Star Anise Oil is widely used in food flavoring and perfumery.

Styralyl acetate is is found in cloves.

It is obtained by direct esterification of acetic acid and methylphenylmethanol in an azeotropic state.

Styralyl acetate is widely used in food flavoring.

Terpene Phenolic Resin (TPR) is obtained by copolymerization of terpene monomer and phenol.

with excellent compatibility, dissolve in all kinds of polar solvent and nonpolar solvent, exhibits excellent.

TPR is also widely used in all kinds of solvent adhesive, dismodule type of CR adhesive, heat solvent adhesive, heat solvent adhesive stick & adhesive tape, and sole adhesive of high-grade shoes.

Terpinen-4-ol is an isomer of terpineol, widely found in various natural plants, especially as the main active component of turpentine oil and tea tree oil, and also found in lavender oil and nutmeg oil. It typically appears as a pale yellow viscous liquid, emitting a mild earthy and woody odour, with fresh herbaceous, camphoraceous, and medicinal nuances.

In addition to its natural occurrence, Terpinen-4-ol can also be prepared by the hydration reaction of sabinene, or produced by the oxidation, hydrogenation reduction, and selective hydrogenation of terpinolene.

Terpineol is a monoterpene alcohol mixture typically derived from the hydration of alpha-Pinene or Gum Turpentine. It is not a single, pure isomer but rather a stable combination of various isomers, including alpha-, beta-, and gamma-terpineol, with alpha-terpineol being its primary and most representative constituent. This product commonly appears as a colourless to pale yellow, viscous, transparent liquid, emitting a pleasant lilac-like fragrance complemented by pine, floral, or citrus notes.

Terpineol is naturally found in pine oil, lavender oil, orange leaf oil, neroli oil and other plant oils.

α-Terpineol, β-Terpineol, γ-Terpineol, and terpinen-4-ol are four isomers of terpineol. α-terpineol is the major component.

Terpineol is a viscous liquid with pine-like and clove-like odor.

Terpineol is widely used in the fragrance formulation, especially in soaps and synthetic detergent.

Terpinolene is one of the constituents of turpentine and an isomer of terpinene. It appears colourless to pale yellow liquid with pine-like odor.

Terpinolene is the byproduct in the production of terpineol. It is used as natural and green food additives.

Thujene is a natural flavoring obtained from Eucalyptus. Thujene is transparent in color with a slight yellow tint.

The term thujene usually refers to α-thujene. A less common chemically related double-bond isomer is known as β-thujene (or 2-thujene). Another double-bond isomer is known as sabinene. Thujene also goes under other names as well 3-Thujene, and Thujiene.

Thujene is often used in the cosmetic and fragrance industries due to its pungent, spicy taste and herbal, woodsy scent.

Thymol is a natural monoterpenoid phenol derivative of cymene, C10H14O, isomeric with Carvacrol, found in oil of thyme, and extracted from Thymus vulgaris (common thyme) and various other kinds of plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties.

Verbenol can be found in verbena oil. It is the product of allylic oxidation of alpha pinene.

It appears white to pale yellow crystalline solid.

Verbenol is mainly used in food, chemical, cosmetic and pharmaceutical industries.

Watermelon Ketone, also known as calone or methylbenodioxepinone is a hydrocarbon compound with similar structure of certain alicyclic C11-hydrocarbons such as ectocarpene. It is a flavor and fragrance chemical compound with special odorant.

The material is prepared by etherification of 4-methylpyrocatechol with two equivalents of alkyl 2-bromoacetate and subsequentDieckmann condensation followed by hydrolysis and decarboxylation.

Pine tar, also call as wood tar or wood tar oil, is a brownish to dark brown viscous liquid.

Foreverest supply wood tar oil (pine tar) for over 20years, the tar oil is prepared by the high temperature carbonization of pine wood under anoxic conditions.

Wood tar oil can be used for impregnating marine cables, rubber plasticizers, caulking rubber and medicine after dehydration or distillation.

α-Terpinyl Acetate (α-TA) is a monoterpene ester and a secondary plant metabolite. It is specifically distinguished from generic “Terpinyl acetate” by its isolated, highly pure isomeric form. While “Terpinyl acetate” often refers to a mixture of isomers (α-, β-, and γ-), α-TA represents a defined chemical entity with consistent properties.

It is naturally found in various plants such as cardamom, thyme, lovage, and laurel, contributing to their aromatic profiles. α-Terpinyl Acetate possesses a sweet, herbal, floral, and distinctly lavender scent. Due to its characteristic aroma and recognised safety, it is widely used as a fragrance component and odorant in daily chemical products. Furthermore, its safety profile allows for its application as a food flavouring additive.

In industrial preparation, α-Terpinyl Acetate can be efficiently synthesised from α-Pinene in the presence of an H-β zeolite catalyst, ensuring a high-purity product.

β-Caryophyllene also known as caryophyllene or (−)-β-caryophyllene. It is a natural bicyclic sesquiterpene that appears colorless to pale yellow oily liquid.
