    TEA and Oil of Olay

    I read that Oil of Olay Facial Cleansing Lotion is 99 % Triethanolamine. Is that the same stuff Patrick Gainer uses for developers?

    And anitfreeze exist in two color variations. Is there a chemical difference significant for developers?

    Where do you buy propylene glycol? I heard it was used as a cow medication?

    Depends on if your area allows anitfreeze (propylene glycol) as the preservative in Dr. Pepper. Bet most of you haven't read the lable on those cans. It wasn't until about 5 years ago that some of the States here decided to ban its use in soda pop.

    If I remember correctly, propylene glycol is used to treat ketosis in cows.

    Propylene Glycol (PG). This very versatile propylene oxide derivative is an ingredient in many consumer products and industrial applications including polyester and alkyd resins, paints and coatings, photographic chemistry, antifreeze coolants and heat transfer fluids, plasticizers, functional fluids, household detergents, industrial solvents, and aircraft deicing fluids. Additionally, USP grade propylene glycol has many uses in foods, pharmaceutical, and personal care products.

    I buy my Propylene Glycol from: http://www.chemistrystore.com/propylene_glycol.htm

    'I read that Oil of Olay Facial Cleansing Lotion is 99 % Triethanolamine. Is that the same stuff Patrick Gainer uses for developers?'

    Why assume that anything you read is true? Yes, there is some idiotic site on the web that says this product contains 99% TEA. As a matter of fact it does. TEA at 99% purity. But the amount in the product is probably a max of 5% or so.

    Relative purity/impurity levels of TEA can have important effects on development. It is important to do your work with TEA of a known quality and stick to it.

    You can't use face cleansing lotion as an ingredient in a film developer.

    What I get from The Chemistry Store is the 99% at about $16 per gallon + shipping. Propylene glycol is the same price. These are grades suitable for use in cosmetics.

    Don't forget freeze conditioning in coal mine production systems and coal-fired power plants. I sell it by the rail-tanker full. How many do you want?
