What it is
In the register’s words: “Thymus Vulgaris Leaf Extract is an extract of the leaves of the Thyme, Thymus vulgaris L., Lamiaceae.”
- EU register name (INCI)
- THYMUS VULGARIS LEAF EXTRACT
- CAS number
- 84929-51-1
- EC number
- 284-535-7
Labels often add a second name in brackets, so a label may say Thymus Vulgaris (Thyme) Leaf Extract where the register says THYMUS VULGARIS LEAF EXTRACT. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Thymus Vulgaris (Thyme) Leaf 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.
- Skin protecting
-
Helps shield skin from outside factors. On a hair label it usually sits beside a conditioning role.
Register definition: “Helping to avoid harmful effects to the skin from external factors.”
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 20th of 31 names
- Jessicurl Deep Conditioning Treatment Deep conditioner 18th 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.
