how much oxalic acid in bar keepers friend
Bar Keepers Friend According to the 2015 material safety data sheet, the ingredients are feldspar, linear sodium dodecyl benzene sulfonate (DDBSA), and oxalic acid.[13] Unlike more abrasive cleaning powders such as Comet and Ajax, Bar Keepers Friend uses oxalic acid as its primary active ingredient.[14] A similar abrasive cleaning product, Zud Heavy Duty Cleanser, also contains oxalic acid.[15] Prolonged use and extended skin contact may cause irritation,[13] peeling and contact dermatitis, which is avoided by wearing gloves. The product can also be an eye irritant.[13]
Vitamin C Vitamin C megadosage is a term describing the consumption or injection of vitamin C in doses comparable to or higher than the amounts produced by the livers of mammals which are able to synthesize vitamin C. The theory behind this, although not the actual term, was described in 1970 in an article by Linus Pauling, a famous scientist who had been awarded the Nobel Prize in Chemistry in 1954. Briefly, his position was that for optimal health, humans should be consuming at least 2,300 mg/day to compensate for the inability to synthesize vitamin C. The recommendation also fell into the consumption range for gorillas - a non-synthesizing near-relative to humans.[177] A second argument for high intake is that serum ascorbic acid concentrations increase as intake increases until it plateaus at about 190 to 200 micromoles per liter (µmol/L) once consumption exceeds 1,250 milligrams.[178] As noted, government recommendations are a range of 40 to 110 mg/day and normal plasma is approximately 50 µmol/L, so 'normal' is about 25% of what can be achieved when oral consumption is in the proposed megadose range.
