Oil Gelation Ability of a Rice Bran Wax and Botanical High-Melting-Point Alcohol Mixture

Abstract

Due to its availability and relatively high melting point, rice bran wax can be used in foods and cosmetics as an oil solidifying agent. The addition of high-melting-point alcohols to the wax to optimize its performance was investigated. Such alcohols were prepared by the hydrolyzation of rice bran wax or carnauba wax. These alcohols had melting points of ~80°C, higher than that of rice bran wax, and consisted of hydrocarbons with alkyl chain lengths ranging from C24 to C34, much longer than the alkyl chains found in commercially available higher alcohols. Oil gel made with only rice bran wax as a solidifying agent has lower hardness than the conventional hydrocarbon wax gel, too low for practical usage in stick cosmetics such as lipsticks and lip creams. Blending high-melting-point alcohols with rice bran wax at 10-20% led to marked increase in gel hardness, equivalent to the gel hardness of the hydrocarbon wax. This effect on rice bran wax was not observed in commercially available higher alcohols and esters with lower melting points. Based upon the change in microstructure observed with SEM, the improved gel hardness of the rice bran wax upon addition of high-melting-point alcohols was probably induced by the disappearance o...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
