Absinth Oil
Absinth Oil, also known as Wormwood Essential Oil, is a highly aromatic essential oil extracted through steam distillation from the leaves and flowering tops of the Artemisia absinthium plant. Native to Europe and Asia and known historically for its use in absinthe liqueur, this oil features a sharp, bitter, herbaceous aroma with a green and slightly medicinal edge. Rich in thujone, chamazulene, and other bioactive compounds, Absinth Oil is known for its antimicrobial, anti-inflammatory, and digestive-stimulating properties.
While traditionally associated with herbal medicine and ritualistic use, modern applications of Absinth Oil span personal care, pharmaceuticals, and natural pest repellents. Due to its intensity and potential toxicity in high concentrations, it is used in very controlled amounts in fragrance and therapeutic blends. It is valued for its distinctive scent and potent botanical properties, particularly in cosmetics, aromatherapy, and natural cleaning formulations.
Ajowan oil
Ajowan Oil, also known as Ajwain Oil or Trachyspermum Ammi Oil, is an essential oil obtained by steam distillation of the seeds of the Trachyspermum ammi plant. With a strong, pungent, thyme-like aroma, Ajowan Oil is rich in thymol—a powerful compound known for its antiseptic, antimicrobial, and digestive properties. Traditionally used in Ayurvedic and Unani medicine, Ajowan Oil is valued today across food preservation, pharmaceuticals, and natural personal care formulations.
This oil exhibits broad-spectrum antimicrobial effects and is widely used in therapeutic balms, oral care, digestive tonics, and antiseptic blends. It also finds applications in fragrance formulations that benefit from its spicy, herbal character. Its potent biological activity makes it effective in natural pest control and disinfectant preparations.
Ambrette Seed oil
Ambrette Seed Oil is a rare, aromatic essential oil derived from the seeds of the Abelmoschus moschatus plant. Known for its rich, musky, slightly sweet, and floral scent, Ambrette Seed Oil is often considered a botanical alternative to animal-derived musk. It is widely prized in high-end perfumery, natural cosmetic formulations, and aromatherapy for its warm, sensual, and long-lasting aroma.
This oil is rich in ambrettolide and farnesol, compounds that lend it a delicate musky note without the synthetic harshness of artificial musks. Ambrette Seed Oil is non-toxic and safe for topical use when diluted, making it ideal for fine fragrances, massage oils, and therapeutic blends.
Methyl Salicylate BP
Methyl Salicylate BP is a clear, colorless to pale yellow oily liquid with a characteristic strong, sweet, and minty odor. It is an organic ester commonly used for its analgesic, anti-inflammatory, and flavoring properties. Methyl Salicylate is widely used in pharmaceutical preparations, topical pain relief products, cosmetics, and as a fragrance ingredient.
Michelia Flower oil
Michelia Flower Oil is an essential oil extracted through steam distillation or solvent extraction from the flowers of Michelia species (e.g., Michelia champaca, Michelia alba). Known for its rich, floral, and slightly fruity aroma, it is widely used in perfumery, aromatherapy, and traditional medicine. The oil is prized for its therapeutic properties and as a natural fragrance ingredient.
Polysorbates
Polysorbates are a class of nonionic surfactants derived from sorbitol and fatty acids, commonly used as emulsifiers, solubilizers, and dispersing agents in a wide range of industries. They improve the mixing of oil and water phases, stabilize emulsions, and enhance the texture and consistency of formulations. Polysorbates are widely used in pharmaceuticals, cosmetics, food products, and industrial applications due to their biocompatibility, low toxicity, and effectiveness at low concentrations.
Propyl paraben
Propyl Paraben is a widely used preservative belonging to the paraben family, known for its antimicrobial properties. It is commonly employed to inhibit the growth of bacteria, mold, and yeast in cosmetic, pharmaceutical, and food products. Propyl Paraben is favored for its effectiveness, low toxicity, and compatibility with a broad range of formulations, helping extend product shelf life while maintaining safety.
Propyl Paraben Sodium BP
 Propyl Paraben Sodium is the sodium salt derivative of propyl paraben, widely used as an effective antimicrobial preservative. It offers improved water solubility compared to propyl paraben and is commonly employed in pharmaceutical, cosmetic, and food products to inhibit the growth of bacteria, molds, and yeasts, thereby extending shelf life and ensuring product safety.
