Transcript of Glycerin
Boiling point(760mm Hg) = 290ºC Glycerin reacts with water and dissolves when in contact with it. Reactions with the chemical mostly take place at neutral positions at 180C where it begins to dehydrate. At lower temperatures Glycerin tends to super cool rather than crystallize. Water solutions created with glycerin resist freezing showing why it is commonly also used in anti-freeze products. Chemical Formula Since the product is mostly harmless to humans it is already a safe substance. The only main cases where Glycerin has harmed humans is through skin creams and lotions where the concentration is too high for some peoples skin and creates a negative reaction making skin irritable. To solve this problem a different product with a different concentration of Glycerin may be necessary. Other than changing products these creams and lotion manufacturers need to test the concentration of Glycerin used on all types of skin to make sure irritability will not be a problem.
Subsitutes Diethylene glycol could be used as a substitute for glycerin in anti-freeze products and act relatively similar to the chemical. Diethylene glycol however could not be used in replacement of any other glycerin products used by humans as it is toxic and carries different properties when interacting with humans.
Ceramides are probably the most likely substitute for glycerin in moisturizers and lotions. In places where Glycerin creates dehydrated skin conditions Ceramides can act as the perfect cure for these problems while carrying out the physical properties Glycerin brings to the product.
