What Are Carbomer?
Not often talked about, but featured in a number of cosmetic products, most people don’t know what Carbomers are, even though they probably benefit from the use of them every day. Unlike active ingredients that offer results-driven value to a product, Carbomer are inactive ingredients that help those active ingredients work so well. “A Carbomer describes a series of polymers made from acrylic acid,” explains Vasyukevich. “On their own, carbomers are white, fluffy powders…

BACKGROUND
Despite the known
benefit of Levodopa in reducing the symptoms of Parkinson's disease, concern has been expressed that its use might hasten neurodegeneration. This study assessed the effect of Levodopa on the rate of progression of Parkinson's disease.
METHODS
In this randomized, double-blind, placebo-controlled trial, we evaluated 361 patients with early Parkinson's…

The broad-spectrum herbicide Glyphosate (common trade name “Roundup”) was first sold to farmers in 1974. Since the late 1970s, the volume of Glyphosate-based herbicides (GBHs) applied has increased approximately 100-fold. Further increases in the volume applied are likely due to more and higher rates of application in response to the widespread emergence of Glyphosate-resistant weeds and new,…

Traditional Chinese medicine commands a unique position among all traditional medicines because of its 5000 years of history. Our own interest in natural products from traditional Chinese medicine was triggered in the 1990s, by Artemisinin-type sesquiterpene lactones from Artemisia annua L. As demonstrated in recent years, this class of compounds has activity against malaria, cancer cells, and schistosomiasis. Interestingly, the bioactivity of Artemisinin and its semisynthetic derivative…

Let us first understand what is acid. An acid is a chemical compound that releases H+ ions in an aqueous solution. We can test the acidic or basic nature of a compound by using an acid-base indicator or litmus paper. Formic acid comes in the carboxylic acid group. It is written as HCOOH and formic acid is the first member of the carboxylic acid group. Formic acid is also known as methanoic acid. To describe in detail, the Formic Acid formula contains 2 oxygen atoms, a single carbon atom, and 2…
