4 Composition of the containers
4.1 General
Essential oils shall be packed in containers which, by their nature, do not cause alteration of the product
and which protect it against any external attack.
Generally, the container materials shall be inert towards the packed product so as to prevent any
simultaneous damage of the product and of the material.

of essential oils.
Essential oils are used for different purposes:
— food use;
— pharmaceutical use;
— perfumery and cosmetic use;
— reference samples or test samples;
— industrial raw materials.
It is expected that the containers used for essential oils also meet the requirements of national or
international regulations.
This document describes the materials which are used for the containers intended for containing
essential oils, depending on the uses listed above.

4 Composition of the containers
4.1 General
Essential oils shall be packed in containers which, by their nature, do not cause alteration of the product
and which protect it against any external attack.
Generally, the container materials shall be inert towards the packed product so as to prevent any
simultaneous damage of the product and of the material.

4.2 Materials for containers intended for containing essential oils for food use
4.2.1 Glass
Type III glass (soda-calcic glass, according to Pharmacopoeia standards), is recommended as it permits
[1]
to keep the organoleptic properties of the essential oils .
Tinted non-actinic glass is always advisable.
4.2.2 Metals and alloys
4.2.2.1 Stainless steel
These materials shall contain at least 13 % of chromium.
They also may contain nickel and manganese.
Furthermore, one or more of the following elements in Table 1 may be included, with the following limit
[2]
for each of them .
Table 1 — Maximum content of some elements in stainless steel containers
Element Content
Tantalum 1 % max
Niobium 1 % max
Zirconium 1 % max
Molybdenum 4 % max
Titanium 4 % max
Aluminium 4 % max
Copper 4 % max
4.2.2.2 Aluminium and aluminium alloys
Aluminium shall be at least 99 % pure.
[3][4][5]
The total content of impurities shall not exceed 1 %, and they are limited as shown in Table 2 .
Table 2 — Maximum content of impurities in aluminium containers
Impurities Content
Iron + Silicon Lower than 1 %
Titanium 0,15 % max
Chromium, Zinc, Copper, Manganese, Magne­ 0,1 % max (for each of these elements)
sium, Nickel, Tin
Lead, Thallium, Beryllium, and each of the 0,05 % max (for each of these elements
other present impurities
Copper Between the mass fraction of 0,10 % and of 0,20 %, on the con­
dition that the chromium and manganese contents are less than
the mass fraction of 0,05 %
In the aluminium alloys, the mass fraction of the elements (in percentage) which may be added, or
which are present as impurities, shall not exceed the following values in Table 3.
