About
A close cousin of the PEG-15/amodimethicone copolymer with one fewer ethylene oxide unit — same silicone-PEG hybrid role, same caveats.
Bis-Isobutyl PEG-14/Amodimethicone Copolymer is structurally almost identical to the PEG-15 analogue but with a slightly shorter ethoxylated block. Function and safety profile are effectively the same: water-dispersible silicone conditioner for hair and skin, delivering smoothing and anti-breakage action. The ethoxylation trace (1,4-dioxane) applies; reputable suppliers purify to <10 ppm. No specific regulatory red flags. Silicone polymers of this family are non-irritating to intact skin but have known environmental persistence.
Skin benefits
- Hair and skin smoothing
- Frizz and breakage reduction
- Easy to incorporate in aqueous systems
- Compatible with most formulation pH
Known concerns
- Trace 1,4-dioxane possible
- Poor environmental biodegradability
- Limited standalone literature
