Vanillin

[Guest guest]

Group,

Below is the email I sent to off list this morning from my office.

It contained information that needed but seeing the posts tonight

on the list about this topic I felt that it was important to provide

this data to the group at large. please note I did not include

that vanillin becomes 16% soluble in 80°C water. You also failed to note

in a follow-up post on this topic that the Merck Index states that

vanillin is soluble in ‘oils’. Rose pointed out that her soaps

containing vanillin turn brown. This is the oxidation that I noted below

in my email to Chris.

You have learned an important lesson the hard way and are indeed lucky

that you have not caused yourself any serious injury. Vanillin is

soluble in water at 1%, 5% in glycerin and freely soluble in ethanol,

chloroform, ether, carbon disulfide, glacial acetic acid, pyridine, oils

and aqueous solutions of alkali hydroxides.

It oxidizes in moist air and is affected by light. It should be stored

in light resistant containers. One part of vanillin is equal to 400

parts vanilla pods. 2.5-3 parts vanillin will replace 500 parts tincture

vanilla in the manufacture of liqueurs. It is also a reagent used in

analytical chemistry. These references are from the Merck Index, 12th

ed.

You need to read the MSDS for it carefully. Whenever you work with any

kind of chemical always maintain good hygiene. Always wash your hands

after handling any chemical compound before touching any mucosal

membranes. This includes your eyes, nose, lips and personal areas. It

also includes any open wounds. One of the primary functions of the skin

is to protect your internal organs from the external environment. When

you have an open wound this is a pathway into the body and needs

protection.
