When the formula is a surfactant, acid or alkali, PET can cloud or stress-crack. HDPE (PE) is the chemical-resistant default. Here is when to switch.
Why HDPE
HDPE resists surfactants, mild acids and alkalis, and is opaque and durable — the safe choice for cleaners, shampoos and body wash.
vs PET
PET is clearer and more premium-looking but weaker against strong actives. HDPE sacrifices clarity for chemical resistance and long-term stability.
Use cases
Shampoos, body wash, surface cleaners and many industrial formulas where the bottle must survive the contents unchanged.

Questions buyers ask us most
When choose HDPE over PET?
For surfactant or acidic/alkaline formulas; choose PET only for clear premium looks on mild formulas.
Can HDPE hold essential oils?
It resists many oils better than PET, but high-load citrus or phenolic oils can still stress it — run a compatibility test first.
