Refined Rice Bran Wax

What is Refined Rice Bran Wax?

Rice bran wax is the by-product obtained by refining edible rice bran oil and then purifying the wax oil, which is generally light yellow solid. Rice bran wax is the ester formed by the advanced fatty acid and the advanced fatty alcohol in rice bran oil, which also includes some advanced free fatty acid, these waxes exist in the oil, and fat when cooling to a certain temperature will crystallize and precipitate, make the oil turbid, affect the quality and appearance of the oil. Meanwhile, bran wax is chemically stable, generally not easy to hydrolyze, and not easy to digest.

Rice bran wax after saponification hydrolysis, solvent extraction of refined rice bran wax, its average molecular weight of 600 ~ 900, containing 55% ~ 60% of the senior fatty alcohols and 40% ~ 45% of the senior fatty acids and fatty acid esters, which contains fatty alcohols for the carbon chain >22C saturated ortho structure of a meta-alcohol, is the same series of a variety of long-chain fatty alcohols of mixtures.

Refined rice bran wax is a kind of pure natural plant wax. Natural rice bran oil contains about 3% of rice bran wax, and after refining steps such as de-oiling, de-gumming, removing impurities, and decoloring, rice bran wax with higher purity is obtained. Refined rice bran wax products have similar properties and are used to a certain extent with natural waxes such as carnauba wax, candelilla wax, and beeswax. Refined rice bran wax has high purity and stability, and has a wide range of applications in food processing and daily chemical processing as well as in chemical production.

Green Spring Technology supplies refined rice bran wax with superior acid value and melting point, it does not use any chemical oxidizing raw materials to whiten in the production process, it is purely physical decoloration of the special process of exquisite, maintains the natural nature, superior quality.

Specification: 

Regulations:

It conforms to EU regulations.

Benefits:

Melting Point

The melting point of refined rice bran wax is 75-80℃, which is higher than beeswax, paraffin wax, and paraffin wax, and only inferior to Sichuan wax, Brazilian carnauba wax, montan wax, and small candle tree wax.

The Rising Power of Melting Point

The rising power of the melting point of rice bran wax is greater than that of low melting point waxes such as beeswax, paraffin wax, and paraffin wax, and slightly lower than that of Kawasaki wax and Brazilian carnauba wax.

Glossiness

Rice bran wax has a very good gloss, 1.2-1.5 times that of Brazilian carnauba wax and beeswax. The more refined the wax, the higher the gloss.

Solvent Absorption

The solvent absorption of Rice Bran Wax is between that of Szechuan Wax, Brazilian Carnauba Wax, Beeswax, and Ground Wax.

Solvent Retention Rate

The solvent retention of rice bran wax is similar to that of Kawasaki wax and Brazilian carnauba wax.

Emulsifying Properties

Rice bran wax can be emulsified to form stable emulsions. High melting point rice bran wax when made into oil-in-water emulsifiers, the emulsifier is required to have a pro-abhorrent balance value of HLB 6-7; low melting point wax is 8-9.

Specific Gravity

The specific gravity of rice bran wax is smaller than that of water, higher than that of soft waxes such as beeswax, and slightly lower than that of hard waxes such as Kawasaki wax and Brazilian carnauba wax. The specific gravity of rice bran wax is 0.97 at room temperature; and 0.78 at 100℃ in liquid state.

Applications:

In Cosmetics:

Rice bran wax has good film-forming properties, it can be used as a skin conditioner in skin care products, forming a film on the surface of the skin to prevent water evaporation. Rice bran wax can also be used as a thickening agent in emulsion, cream, and other products to improve the consistency of the formula, but does not produce a sticky feeling; In addition, rice bran wax can be used in sunscreen products to improve the SPF value, enhance the skin's ability to resist ultraviolet rays, prevent skin sunburn. ability and prevent sunburn of the skin.

Fiber Manufacturing:

Adding rice bran wax can improve the flexibility, smoothness, and gloss of fiber products, and can produce better quality fiber products. In addition, rice bran wax can also be used as a stabilizer or lubricant, as well as an excellent heat-resistant thickener in petroleum and lubricants.

In the Food Field:

Rice bran wax is used in the preservation of vegetables and fruits, food packaging, and as an adjunct to confectionery such as flavored candies. The U.S. Food and Drug Administration permits the direct addition of rice bran wax to food products, and it is also included on the list of indirect food additives that can be used as mold release agents.

In the Industrial Field:

Rice bran wax can also be used in floor wax, automobile wax, polish wax for leather and furniture, etc.; and as raw material for printing material, ink, pigment, copy paper, glossy paper, photo paper, etc.
