Allergies And Perfume
There are various elements that are considered in the preparation of any perfume. If you are buying perfume, it is worth being able to understand what the perfume manufacturer displays on the bottle. To make the right choice, it is worth knowing what to look for. No one would eat food that was not clearly labelled, yet many people are uncertain of their perfume ingredients or the preparation methods that create them. This is particularly important in modern times when pollution levels have increased sensitivity and allergy levels.
Firstly, the concentrate of the blend of the perfume that you choose has a high impact on allergies. If you have intolerance to the ingredients that create the fragrance, then you can control this to a degree. The lowest concentrated blend is found in Eau de Cologne, which has a maximum of 5% pure perfume ingredients. This means that any reaction will be minimal in comparison to the other strength perfumes that are available. The next lowest strength perfume is Eau de Toilette which has a concentration of between 4% and 10% of perfume ingredients. The Eau de Perfume will contain between 8% and 15% pure perfume, whilst any labelled Perfume is the strongest with between 15% and 25% pure strength ingredients. Read more

Sterling Silver and Allergies to Metal
Sterling Silver and Allergies
The truth is people are not usually allergic to silver or sterling silver. Rather a metal known as nickel, which has been used in sterling silver. Sterling silver is an alloy consisting of 92.5% silver and 7.5% other metals, traditionally copper, and sometimes some manufacturers will use nickel in sterling silver as a less expensive alternative to other metals.
Why Sterling Silver?
Pure silver is too soft to produce any functional pieces and loses shape too easily. Other metals are added to improve qualities such as ductility, firescale, tarnish resistance, and reducing casting porosity.
Why Nickel?
Nickel, is a hard and ductile, silvery white metal that has been mistaken for silver in the past. Nickel is commonly used in jewelry including with precious metals jewelry such as gold, white gold, sterling silver and platinum and also most cheap or costume jewelry. Nickel is what gives white gold it’s white color by alloying more of it with yellow gold, as gold is not found naturally white or any other color than yellow. Other metals are used to make other colors of gold, for instance silver is used to make green gold and copper is used to make rose gold. Nickel adds many other properties besides color, such as strength and durability, and it has a strong lustrous effect. Read more
