What it is
In the register’s words: “Rosmarinus Officinalis Flower/Leaf/Stem Extract is an extract of the flowers, leaves and stems of the Rosemary, Rosmarinus officinalis L., Lamiaceae.”
- EU register name (INCI)
- ROSMARINUS OFFICINALIS FLOWER/LEAF/STEM EXTRACT
- CAS number
- 84604-14-8
- EC number
- 283-291-9
Labels often add a second name in brackets, so a label may say Rosmarinus Officinalis (Rosemary) Flower/Leaf/Stem Extract where the register says ROSMARINUS OFFICINALIS FLOWER/LEAF/STEM EXTRACT. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Rosmarinus Officinalis (Rosemary) Flower/Leaf/Stem Extract 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.”
- Skin conditioning
-
The register’s broad role for ingredients that keep skin in good condition. On a hair label it often sits beside a hair role, or marks a plant oil or extract.
Register definition: “Maintaining the skin in good condition.”
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.
- Rinse-out conditioners 1 label First five names: 0 of 1 Rinse-out conditioners without it
- Deep conditioners 1 label First five names: 0 of 1 Deep conditioners without it
Every label, product by product (2)
- Jessicurl Too Shea! Extra Moisturizing Conditioner Rinse-out conditioner 12th of 31 names
- Jessicurl Deep Conditioning Treatment Deep conditioner 10th of 30 names
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.
