Ingredient review
Polyquaternium-114
INCI: Polyquaternium-114
A gentle synthetic polymer that smooths hair and skin without heavy buildup, ideal for sensitive scalps.
In plain English
Polyquaternium-114 is a man-made polymer (a long chain of repeating molecules) that sticks to hair and skin. It forms a thin, flexible film that makes hair feel softer, reduces frizz, and helps detangle. On skin, it can leave a silky, non-greasy feel. Because it's water-soluble, it rinses off easily and doesn't pile up with repeated use.

Quick decision guide
Useful, but context matters
Polyquaternium-114 is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Polyquaternium-114.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic, positively charged polymer designed to condition hair and skin by forming a smooth, flexible film.
How it works
Its positive charge attracts it to negatively charged hair and skin surfaces. Once deposited, it creates a thin, even layer that smooths the cuticle, reduces static electricity, and improves slip for easier combing. On skin, it provides a soft, velvety after-feel without clogging pores.
Pros
Lightweight conditioning
Provides smoothness and detangling without heavy buildup, making it great for fine hair.
Low irritation potential
Generally well-tolerated even on sensitive skin and scalps, with low risk of stinging or redness.
Cons and cautions
Not fully biodegradable
As a synthetic polymer, it may persist in the environment longer than natural alternatives.
Can cause buildup with silicones
When used alongside certain silicones, it may contribute to a dull or coated feel over time.
Best for
- People with fine or easily weighed-down hair
- Those looking for a gentle conditioner for sensitive scalps
Use caution if
- Individuals with known sensitivity to quaternary ammonium compounds
Usage tips
Safety summary
Polyquaternium-114 is considered safe for use in cosmetics at typical concentrations. It has low skin and eye irritation potential and is not known to be sensitizing. Always patch test if you have very sensitive skin.
Research notes
Studies on polyquaternium polymers generally show good safety profiles. Specific data on Polyquaternium-114 is limited, but it is structurally similar to other well-studied polyquaterniums with established safety.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Conditioners, Leave-in treatments, Styling products, Shampoos, Body washes
- Environmental note
- As a synthetic polymer, it is not readily biodegradable. However, it is used at low concentrations and is water-soluble, which helps reduce accumulation.
Good to know
- Polyquaternium-114 is often chosen for its ability to condition without making hair limp.
- It is compatible with many other conditioning agents and thickeners.
