Ingredient review
Polyquaternium-113
INCI: Polyquaternium-113
Polyquaternium-113 is a gentle conditioning polymer that helps detangle hair and improve product feel without heavy buildup.
In plain English
Polyquaternium-113 is a positively charged polymer that sticks to the negatively charged surfaces of hair and skin. In hair products, it reduces frizz and static, making hair easier to comb and softer to the touch. In skincare, it can create a smooth, silky feel on the skin without leaving a greasy residue. Because it forms a thin film, it also helps other ingredients stay on the skin or hair longer.

Quick decision guide
Useful, but context matters
Polyquaternium-113 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-113.
- 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
Polyquaternium-113 is a synthetic, water-soluble polymer belonging to the polyquaternium family. It is designed to condition and protect hair and skin by forming a flexible, non-sticky film.
How it works
The molecule carries a positive charge, which allows it to bind to the negatively charged surfaces of hair and skin. This binding creates a thin, even film that smooths the cuticle, reduces static electricity, and improves the sensory feel of the product. In rinse-off products, it deposits enough to provide conditioning without heavy buildup.
Pros
Excellent detangling
Helps hair comb through easily when wet, reducing breakage and making styling less frustrating.
Lightweight feel
Does not leave a heavy or greasy residue, making it suitable for daily use in shampoos and conditioners.
Cons and cautions
Potential buildup
Over time, especially with frequent use, it can accumulate on hair, leading to dullness or stiffness, particularly in fine hair.
Not eco-friendly
As a synthetic polymer, it is not readily biodegradable and may contribute to environmental persistence in waterways.
Best for
- People with frizzy or dry hair seeking smoother texture
- Those who want a lightweight conditioner without heavy oils
Use caution if
- Individuals with very fine or low-porosity hair who experience buildup easily
- Anyone seeking fully biodegradable or natural ingredients
Usage tips
Safety summary
Polyquaternium-113 has a low irritation and comedogenic risk. It is considered safe for most skin and hair types when used in typical cosmetic concentrations. However, like all synthetic polymers, it is not biodegradable.
Research notes
Studies on polyquaternium compounds generally support their safety and efficacy as conditioning agents. Specific data on Polyquaternium-113 is limited, but it is structurally similar to other well-studied polyquaterniums. The Cosmetic Ingredient Review (CIR) panel has reviewed related polyquaterniums and found them safe for cosmetic use.
Common label clues
- Typical concentration
- 0.1% to 2% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Generally recognized as safe when used as directed.
- Common uses
- Conditioners, Shampoos, Leave-in treatments, Styling products, Body washes
- Environmental note
- Polyquaternium-113 is not biodegradable and may accumulate in aquatic environments. Some manufacturers are exploring more eco-friendly alternatives.
Good to know
- Polyquaternium-113 is often used in combination with other conditioning agents to balance feel and performance.
- It is considered safe for color-treated hair as it does not strip color.
