Simultaneous identification by liquid chromatography of benzethonium chloride
, methyl paraben and triclosan in commercial products labeled as grapefruit seed extract.
Further, the USDA did a grapefruit seed extract study and declared, "Confirming an earlier study by researchers in Germany, we found that some commercial grapefruit seed extracts contain benzethonium chloride
, a synthetic antimicrobial agent commonly used in cosmetics and only approved for topical use, at relatively high levels of eight percent.
To determine if Mycoplasma organisms could survive in the vaccine, which contains formaldehyde and benzethonium chloride
, a fifth lot of vaccine (FAV038) was obtained and evaluated.
While the door has been left open for materials such as chloroxylenol, benzalkonium chloride and benzethonium chloride
, the cost of safety and efficacy testing is burdensome.
In response to comments submitted by industry, the FDA has deferred rulemaking for one year on three additional ingredients used in consumer wash products benzalkonium chloride, benzethonium chloride
and chloroxylenol (PCMX) to allow for the development and submission of new safety and effectiveness data for these ingredients.
We investigated the effect of hemolysis on Pyrogallol Red (PYR) (2), benzethonium chloride
(BTC) (3), and benzalkonium chloride (BC) (4) methods for measurement of protein.
The culture filtrate is adsorbed to aluminum hydroxide and formulated with benzethonium chloride
(preservative) and formaldehyde (stabilizer).
FDA has deferred rulemaking for a year on three additional ingredients used in consumer wash products--benzalkonium chloride, benzethonium chloride
and chloroxylenol (PCMX)--to allow for the development and submission of new safety and effectiveness data for these ingredients.
28%; Lever 2000 Anti-bacterial Moisturizing Wipes with benzethonium chloride
Linearity of TUP measured simultaneously by the benzethonium chloride
method (Roche Diagnostics) was very good for the sample with [kappa] FLC (9 dilutions; range, 0.
FDA has deferred rulemaking on those three ingredients: benzalkonium chloride, benzethonium chloride
and chloroxylenol," explained Brian Sansoni, VP-communication and membership andVP-sustainability initiatives.
Urinary protein can be determined by turbidimetric assays using trichloroacetic acid (1), sulfosalicylic acid (2), or benzethonium chloride
(BTC) (3, 4); the biuret assay (5, 6); or protein dyebinding assays using Coomassie Brilliant Blue (CBB) (7-13), Pyrogallol Red (PYR)-molybdate (14,15), or Ponceau S (16).
