Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Urushiol shopping experience:

1. Compare - without doubt the biggest advantage that the Urushiol offers shoppers today is the ability to compare thousands of Urushiol at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Urushiol? Wrong! If the Urushiol is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Urushiol then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Urushiol? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Urushiol and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Urushiol wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Urushiol then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Urushiol site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Urushiol, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Urushiol, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

Urushiol (International Phonetic Alphabet: ) is an oil found in plants of the Linnaean taxonomy Anacardiaceae, especially Toxicodendron spp. (e.g. poison oak, poison ivy, and poison sumac). It is also found in the nut shell of cashew fruit (Anacardium occidentale) and on the skin of the mango fruit. It causes an allergic skin rash on contact, known as urushiol-induced contact dermatitis. The name comes from the Japanese language word urushi, which denotes a lacquer produced in East Asia from the sap of kiurushi trees (Lacquer Tree). The oxidation and polymerization of urushiol in the tree's sap in the presence of moisture allows it to form a hard lacquer, which is used to produce traditional Chinese and Japanese lacquerwares.

Urushiol is a yellow liquid with a boiling point of 200-210 °C. It is miscible partially in alcohol and ether, but nearly immiscible in water. Chemically, urushiol is a mixture of several closely related organic compounds. Each consists of a catechol substituted with an alkyl chain that has 15 or 17 carbon atoms. The alkyl group may be Saturation (chemistry) or unsaturated, urushiol oil is a mixture of the saturated and unsaturated urushiol molecules. The exact mixture depends on the species of the plant. For example, poison oak urushiol contains mostly catechols with C17 side chains, but poison ivy and poison sumac contain mostly catechols with C15 side chains. The allergic reaction is dependent on the degree of unsaturation of the alkyl chain. Less than half of the general population reacts with the saturated urushiol alone, but over 90% react with urushiol containing at least two degrees of unsaturation (double bonds).{| align = "center"||R = (CH2)14CH3 or
