Jump to a section

Origanum Majorana (Marjoram Sweet) Leaf Oil is on 6 of the 177 hair-product labels we compare, from 1 maker. Its uses in the EU ingredient register are fragrance and refreshing. None of these labels names it among its first five ingredients.

What it is

In the register’s words: “Origanum Majorana Leaf Oil is the volatile oil distilled from the leaves of the Sweet Marjoram, Origanum majorana L., Labiatae.”

EU register name (INCI)
ORIGANUM MAJORANA LEAF OIL
CAS number
84082-58-6
EC number
282-004-4

Labels often add a second name in brackets, so a label may say Origanum Majorana (Marjoram Sweet) Leaf Oil where the register says ORIGANUM MAJORANA LEAF OIL. Both are the same ingredient.

What the register lists it for

These are the uses the European Commission’s CosIng register lists for Origanum Majorana (Marjoram Sweet) Leaf Oil in any cosmetic, hair roles first. They say why a maker might add it, not what it does in one formula, and they aren’t a safety rating.

Fragrance

Gives the product its smell or covers an unpleasant one. A label may name each scent ingredient or group them as Fragrance (Parfum).

Register definition: “Imparting an odour or taste. Creating a perceivable pleasant smell and/or masking a bad smell.”

Refreshing

Gives a fresh, cool feel on the skin. Menthol and mint oils carry this role.

Register definition: “Imparting a pleasant freshness to the skin.”

Where it sits on each label

US labels list ingredients from most to least, except that those at 1% or less may follow in any order. A name near the top is a large part of the formula. A label doesn’t mark where the 1% point falls, so further down, the order says little about how much is in it.

Every label, product by product (6)

Each line runs from the first name on a label to the last; a dot is where this ingredient sits. Makers change formulas now and then; if the list on your bottle differs, go by your bottle.
