What it is
In the register’s words: “Piper Nigrum Seed Extract is an extract of the seeds of Black Pepper, Piper nigrum L., Piperaceae.”
- EU register name (INCI)
- PIPER NIGRUM SEED EXTRACT
- CAS number
- 84929-41-9
- EC number
- 284-524-7
- Written on these labels as
- Piper Nigrum (Black Pepper) Seed Extract; Piper Nigrum (Pepper) Seed Extract
Labels often add a second name in brackets, so a label may say Piper Nigrum (Black Pepper) Seed Extract where the register says PIPER NIGRUM SEED EXTRACT. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Piper Nigrum (Black Pepper) Seed 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.
- 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.”
- Tonic
-
The register’s role for ingredients said to give skin and hair a feeling of well-being. Many plant extracts carry it.
Register definition: “Producing a feeling of well-being on skin and hair.”
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.
