Cetyl Stearyl Alcohol (CSA)
Cetyl Stearyl Alcohol (CSA), also known as Cetearyl Alcohol, is a blended fatty alcohol consisting primarily of cetyl (C16) and stearyl (C18) alcohols. It appears as white to pale yellow waxy flakes or pellets with a mild fatty odor. CSA is widely used in cosmetics, pharmaceuticals, and personal care products as an emollient, thickener, and co-emulsifier. It enhances texture, improves stability, and provides a smooth, velvety skin feel in formulations. Being a non-ionic surfactant, it also aids in stabilizing oil-in-water emulsions and is favored for its gentle nature on the skin and hair.

Almond Wax
Almond Wax is a natural, plant-based wax derived from the hydrogenation of almond oil (Prunus amygdalus dulcis). It is a creamy to white, semi-solid wax with a mild, nutty scent and excellent emollient properties. Almond Wax is rich in fatty acids and has a smooth, soft texture, making it ideal for use in cosmetic, personal care, and candle formulations.
Due to its gentle consistency, skin-friendly profile, and moisturizing capabilities, Almond Wax is widely used in body butters, balms, lip care products, massage bars, and artisan soaps. It functions as a natural alternative to petroleum-based waxes and provides structure, viscosity, and glide to formulations. It also finds application in soft wax blends for natural candle products.
Camelia Oil Infused
Camelia Oil Infused is a gentle, nutrient-rich botanical oil made by infusing the flowers or leaves of the Camellia sinensis or Camellia japonica plant into a carrier oil such as olive, jojoba, or sweet almond oil. Unlike cold-pressed camellia seed oil, this infusion captures a wider spectrum of antioxidant polyphenols, flavonoids, and saponins from the plant material, delivering enhanced skin and hair benefits. Known for its lightweight, non-greasy texture and rapid absorption, Camellia Infused Oil is deeply moisturizing and ideal for sensitive, dry, or aging skin.
Popular in Japanese and Korean beauty traditions, this oil is often used to promote skin elasticity, smoothness, and overall rejuvenation, making it a preferred ingredient in natural cosmetic and personal care products.
Canola Oil
Canola Oil is a light, non-greasy vegetable oil extracted from the seeds of the Canola plant (Brassica napus, Brassica rapa), a cultivar of rapeseed developed for its low erucic acid content. Rich in monounsaturated fats, omega-3 and omega-6 fatty acids, and vitamin E, it is known for its heart-healthy profile and neutral flavor.
Widely used in the food, cosmetic, pharmaceutical, and industrial sectors, Canola Oil serves as a versatile base oil for cooking, skincare formulations, softgel encapsulation, and biodiesel production. Its high smoke point and oxidative stability make it ideal for both cold and high-temperature applications.
Ceto Stearyl Alcohol
Ceto Stearyl Alcohol 1618TA is a high-quality fatty alcohol blend primarily composed of cetyl (C16) and stearyl (C18) alcohols. It appears as a white, waxy solid or flakes with a mild fatty odor. This blend is widely used as an emollient, thickener, and co-emulsifier in cosmetic, pharmaceutical, and industrial formulations. Ceto Stearyl Alcohol 1618TA offers excellent lubricity, thickening, and stabilizing properties, enhancing the texture, consistency, and moisturizing characteristics of creams, lotions, and hair care products. It serves as a skin conditioning agent and contributes to the structural integrity of emulsions.
Dimethicone Silicon Oil
Dimethicone Silicon Oil, also known as polydimethylsiloxane (PDMS) or silicone oil, is a clear, odorless, and non-volatile silicone-based polymer widely used for its lubricating, anti-foaming, water-repellent, and skin-conditioning properties. It is a linear silicone polymer composed of repeating dimethylsiloxane units. Dimethicone exhibits excellent thermal stability, chemical inertness, and low surface tension, making it highly versatile in pharmaceutical, cosmetic, personal care, industrial, and food applications. It is available in various viscosities, from very low to high viscosity oils, enabling tailored formulations.
Isopropyl Palmitate
Isopropyl Palmitate IPP is a clear, colorless to pale yellow oily liquid formed by the esterification of isopropyl alcohol and palmitic acid. It has a mild odor and is widely used in cosmetic, pharmaceutical, and industrial formulations as an emollient, lubricant, and solvent. IPP is valued for its excellent skin absorption, non-greasy feel, and ability to improve texture and spreadability of topical products.
Jojoba Wax
Jojoba Wax is a natural, golden-yellow to amber-colored wax ester extracted from the seeds of the jojoba plant (Simmondsia chinensis). Unlike traditional vegetable oils, jojoba wax is chemically a liquid wax, known for its excellent stability, moisturizing properties, and similarity to human sebum. It is odorless or mildly nutty and is widely used in cosmetics, personal care, and pharmaceutical applications as an emollient, thickener, and skin conditioning agent.
Lanolin Anhydrous
Lanolin Anhydrous is a purified, waxy substance derived from the sebaceous glands of sheep’s wool. It appears as a yellow to amber, semi-solid wax with a characteristic mild odor. Lanolin is highly valued for its excellent emollient, moisturizing, and protective properties, making it widely used in cosmetic, pharmaceutical, and personal care formulations. The anhydrous form is free from water, which enhances its stability and shelf life, and allows it to act as a natural barrier to lock moisture into the skin.
