CASTOR WAX

EC / List no.: 232-292-2
CAS no.: 8001-78-3
Mol. formula: C57H110O9

Castor wax, also called hydrogenated castor oil, is an opaque, white vegetable wax. 
Castor wax is produced by the hydrogenation of pure castor oil often in the presence of a nickel catalyst to increase the rate of reaction.
The hydrogenation of castor oil forms saturated molecules of castor wax; this saturation is responsible for the hard, brittle and insoluble nature of the wax.

Castor wax is prepared by hydrogenation of castor oil, and its main component is 12-hydroxystearic acid triglyceride. 
Castor wax is white to light yellow powder, lumps or flakes. Castor wax is slightly soluble in methylene chloride, insoluble in petroleum ether, very slightly soluble in ethanol, insoluble in water.

Uses:
Castor wax is used in polishes, oils paints (Old Holland, Lefranc), cosmetics, electrical capacitors, carbon paper, lubrication and coatings and greases where resistance to moisture, oils and petrochemical products is required. 
Castor wax is also useful in polyurethane coating formulation, as it contains three secondary hydroxyl groups. 
These coating compositions are useful as a top coat varnish for leather, wood and rubber.
Castor wax can also be added to beeswax for encaustic painting.

Hydrogenated castor oil is a waxy compound obtained by the hydrogenation of refined castor oil. 
Castor wax is a hard product with a high melting point. 
Castor wax is almost odourless and tasteless. 
HCO is supplied in flakes and powder. Hydrogenated castor oil is cream to white coloured.

Hydrogenated castor oil occurs as a fine, almost white or pale yellow powder or flakes. 
The PhEur 6.0 describes hydrogenated castor oil as the oil obtained by hydrogenation of virgin castor oil. 
Castor wax consists mainly of the triglyceride of 12-hydroxystearic acid.

Hydrogenated castor oil — also called HCO or castor wax — is a hard, white, opaque vegetable wax. 
Its resistance to moisture makes it useful in many coatings, greases, cosmetics, polishes and similar applications.
The wax is created by hydrogenating pure liquid castor oil, which is obtained from castor beans. 
The oil is heated under extreme pressure using a nickel catalyst during the hydrogenation process. 
Afterward, the hydrogen creates saturated molecules of castor wax, which gives the oil a higher melting point that allows it to remain solid at room temperature. After hydrogenation, the oil becomes hard and brittle to the touch.

Uses:
1- greases: Lithium- and Calcium hydroxystearates dispersed in base oil to make multipurpose greases having higher dropping points, hardness, better rust-proofing, lubricity and durability than stearates.

Castor Wax: What is it?
Castor wax or hydrogenated castor oil (HCO) is a derivative of castor beans (Ricinus communis), which is typically present in the form of a liquid at room temperature. One can find the vegetable wax in its unmodified state in the form of hard crumbly block. Castor wax works well with other oils and waxes in the antiperspirant base, giving the stick a firm, yet spreadable consistency.

Properties of Castor Wax
Castor wax, a cream to white coloured, is flaky or powdered in nature. Castor wax is odourless and insoluble in water; hence, it does not wash away easily. Castor wax has a density of 0.970 at 20⁰C, with melting point at 83-87⁰C. 
Like pure castor oil, castor wax is rich in triglycerides received from ricinoleic acid and highly used in several products for its unique properties.

Castor wax has lipo gelling properties, which means it helps in reduction of fat and cellulite from the body, especially in arms, legs and abdominal region. 
Besides, it helps in stabilizing the emulsions, thereby favouring mixtures of liquids. Lastly, it acts as a viscosity-controlling agent.

Making of Castor Wax
The castor oil manufacturers produce castor wax or Castor wax (HCO) following a process called hydrogenation. 
The process involves chemical combination of elemental hydrogen and hence the name hydrogen castor oil.
 In the presence of nickel catalyst, pure castor oil gets hydrogenated, which increases the melting point of the final product. 
During the process of manufacturing castor wax, the manufacturers bubbles hydrogen gas into castor oil. 
The process improves the taste, odour and other qualities of the final product. 
Besides, the process gives a viscous waxy consistency, which is none other than castor wax. However, for obtaining best results, the process requires high concentration of nickel.

Castor Wax is a castor oil derivative. 
Castor wax is used as an emollient and thickening agent in ointments and deodorants. 
Because of the meltpoints of either 70 or 80, Castor Wax is often preferred over standard HCO for Personal Care applications, as well as in Textile processing.

Castor wax, also called Castor wax, is an opaque, white vegetable wax. 
Castor wax is produced by the hydrogenation of pure castor oil often in the presence of a nickel catalyst to increase the rate of reaction. 
The hydrogenation of castor oil forms saturated molecules of castor wax; this saturation is responsible for the hard, brittle and insoluble nature of the wax.

Castor Wax, also known as Castor wax is a useful wax to thicken and harden a wide range of products.  Castor wax is derived from the Castor Bean, and after the oil is extracted from the bean, it is bubbled with hydrogen gas to produce a wax.  Common uses include;

Bar Soaps: Add to cold process and hot process soaps to make a firmer bar

Skincare: Can be used to thicken skincare products such as creams and lotions

Haircare: Can be used to help thicken conditioners and hair styling products

Balms: Combine with vegetable oils, essential oils and beeswax to produce a skin balm

Castor wax is derived from castor oil. 
Castor wax is also known as Castor wax. 
This vegetable wax is a little hard in consistency. 
Castor wax neither carries any odor nor can be dissolved in water. 
Castor wax is tasteless. Castor wax forms a smooth emulsion when mixed with emulsifiers. 
Castor wax is also compatible with number of other waxes like carnauba wax, beeswax and candelilla wax. 
Castor wax remains insoluble in most of the solvents. 
However, at higher temperature it dissolves in certain solvents and oils. 
Once cooled it takes the form of a gel or a paste. 
Castor wax is highly compatible with other animal, vegetable and mineral waxes.

Production of castor wax
Castor wax is produced by a process known as hydrogenation. 
This process involves chemical combination with element hydrogen and hence the name. 
Pure castor oil undergoes hydrogenation in presence of a nickel catalyst. 
Process of hydrogenation raises melting point. 
Castor wax also improves odor, taste and other qualities of resulting product. In this process, hydrogen gas is bubbled into castor oil. Resulting product so obtained gives a viscous waxy consistency which is nothing but castor wax. 
High concentration of nickel catalyst is required for good results. Reaction taking place is exothermic.

Uses of castor wax
