Guest guest Posted March 2, 2002 Report Share Posted March 2, 2002 This is probably a very dumb question, but I've searched and tried to figure this out for weeks now. I am finally going to break down and subject myself to snickers by asking, but...what does PEG stand for? Is it an industry standard? A brand name? An acronym for " Pretty Enormous Gonads " ? (sorry) But, I see this as PEG 16 or PEG 50 and then the product or INCI name after that. I humble myself before the experts...I'm not worthy, I'm not worthy. n Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 2, 2002 Report Share Posted March 2, 2002 I am most certainly NOT an expert, but I am very good at copying out of reference books! :-) According to A Consumers Dictionary of Cosmetic Ingredients: " Abbreviation for polyethylene glycol/polyethylene, used in making non-ionic surfactants " PEG?

Guest guest Posted March 2, 2002 Report Share Posted March 2, 2002 >> " Abbreviation for polyethylene glycol/polyethylene, used in making >>non-ionic >> surfactants " So...what does it mean when I see it as for example... PEG-16 Macademia Glycerides? I mean, if it stands for polyethylene glycol, does this mean that polyethylene glycol can be derived from many different things, and that this particular polyethylene glycol was derived from Macademia Nuts? And what do the different numbers mean? n Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 2, 2002 Report Share Posted March 2, 2002 what that means is that it's the polyethylene glycol ester of the fatty acids in macadamia nut oil. the higher the PEG number, the more solid the product. So PEG 150 Distearate (stearic acid) would be a lot more solid than your PEG-16 Macadamia Glycerides. If I understand correctly, the PEG makes the oil or fatty acid more water soluble - " blooming " or " dispersible " bath oils are made with PEG-x oils. The PEG isn't derived from the oils, its reacted with them.

Jules, I looked up ester in the dictionary: " Any of a class of organic compounds corresponding to the inorganic salts formed from an acid by the replacement of hydrogen by an alkyl radical. " Yikes, some things come to me so easily, but chemistry isn't one of them. Does this mean that the PEG 16 Macadamia Glycerides don't really contain any Macadamia Oil, but only something that has REACTED with, or to, the Macadamia Oil? Or is it a combination of both? I'm sorry to be so dense. n Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 2, 2002 Report Share Posted March 2, 2002 Maurice will probably hold his head in pain and scream at this description, but think of it kind of like macadamia oil soap...it's made with macadamia oil, and it still sort of is macadamia oil, but at the same time, it's more than macadamia oil. Does that make any sense?

Guest guest Posted March 2, 2002 Report Share Posted March 2, 2002 not quite...the new product is called " PEG-6 Macadamia Glycerides " (or whatever the number was - I can't recall now!) But yup, otherwise you've got it. Just like PEG-150 Distearate is a reacted form of stearic acid that now acts as an emulsifier and thickener. Macadamia Glycerides, IMO, is basically a fancy way of saying " macadamia oil " ...there is a slight difference, I believe, between it and macadamia oil, but not much...oil is a triglyceride (three fatty acids attached to one glycerol molecule)...perhaps this is to imply that there are mono- and di-glycerides in the stuff as well? That much I don't know. I'm sure if I'm way off base Maurice or Pat or someone else will correct me! *g* The PEGs are pretty nifty things to work with, from what I understand. A couple of places sell a " PEG " ed sunflower oil that's supposed to be lovely as a bath oil.
