The high-HLB partner in the classic pair
Tween 80 at HLB 15 is almost always used alongside Span 80 to build a stable O/W or W/O emulsion pair. The blend ratio sets the effective HLB of the system, which is the standard formulation lever.
Solubilising flavours and vitamins
Above its critical micelle concentration, Tween 80 solubilises essential oils and fat-soluble vitamins into clear aqueous systems. That is why it appears in beverage flavour emulsions and in vitamin preparations where clarity is required.
Typical Applications
- Beverage flavour emulsions — 0.05-0.2 percent solubilises citrus oils into clear drinks.
- Ice cream — 0.1-0.3 percent improves overrun and melt resistance.
Frequently Asked Questions
Is there a use limit in the EU?
E433 has maximum levels per food category; beverages and dairy have specific caps, so check the annex.
Why does it taste slightly soapy at high dose?
Above about 0.3 percent the surfactant note becomes detectable. Reduce the dose or shift the HLB balance.
Can it replace sucrose esters?
In many systems yes, though the clean-label positioning differs and the use level is usually higher.
