Mallow Extract
INCI: Malva Sylvestris Flower/Leaf/Stem Extract
A pale green-amber extract from the common mallow flower. High in mucilage; soothing, hydrating, and naturally astringent.
Overview
Common mallow (Malva sylvestris) is a flowering plant widespread across Europe, North Africa, and West Asia. The flowers, leaves, and sometimes stems are used to make a soft, faintly herbaceous extract that has been a fixture in European herbal medicine for centuries.
The defining active is mucilage — natural water-binding polysaccharides that swell and form a soft, gel-like film on contact with water. This is the same family of compounds that give marshmallow root extract its silky soothing quality.
Other active compounds include:
- Anthocyanins (from flowers) — antioxidant, give a faint colour
- Flavonoids — broader antioxidant and anti-inflammatory
- Tannins — mild astringent
- Phenolic acids — antioxidant support
Cosmetic extracts come as a light green-amber liquid in water/glycerin form, with a faint herbaceous smell.
Shelf life is 12-18 months for liquid form.
What it does in a formula
- Skin soothing — mucilage forms a soft cushioning film on irritated skin
- Mild humectant action from polysaccharides
- Anti-inflammatory — flavonoid content reduces reactive skin
- Mild astringent feel — tannins, useful for combination skin
- Antioxidant support
It is one of the gentlest botanical extracts in the toolbox. It does not have a headline active claim — no dramatic brightening or anti-aging — but it consistently shows up in baby creams, eczema balms, and ultra-sensitive face formulas because it adds calming character without irritation risk.
How to use
Add to the cool-down phase, below 40 C.
Usage rates by product type:
- Baby skincare: 2-4%
- Sensitive-skin lotions: 2-4%
- Eczema-supporting balms (water phase): 2-4%
- Calming toners: 1-3%
- After-sun lotions: 1-3%
- Eye creams: 1-3%
It pairs naturally with marshmallow root extract (similar mucilage profile), with chamomile, with oat extract, and with calendula.
Best for / Worst for
Best for: baby and child skincare, sensitive-skin formulations, after-sun lotions, eczema-supporting products, calming toners, eye creams, post-procedure recovery products.
Worst for: maximum-potency formulations, customers expecting headline active claims, strict colour-neutral white products (the green-amber tint can show).
Common pitfalls
Overstating activity. Mallow is a supporting ingredient. Position it for what it does (gentle calming, mild humectant) rather than as a star.
Heat sensitivity. Add to cool-down phase. Anthocyanins and flavonoids degrade above 50 C.
Differentiation from marshmallow. Common mallow (Malva sylvestris) and marshmallow (Althaea officinalis) are different but related plants. Both are in the encyclopedia. Their roles overlap heavily — mallow tends to lean slightly more on the flower antioxidants; marshmallow leans more on root mucilage.
Substitutes
- Marshmallow root extract — closely related, similar role.
- Linden flower extract — similar gentle calming.
- Chamomile extract — different chemistry, similar gentle role.
- Oat extract — different chemistry, similar gentle skin-calming.
- Hyaluronic acid + bisabolol — for measurable hydration + calming.
