MLB – a unique W/O emulsifier

MLB – which stands for Moisture Lifting Base – is the name of our W/O emulsifier system by Sunjin, Korea. This emulsifier stands out for its excellent emulsion performance at low application concentration. Accordingly, it even disperses pigments and other powders excellently. MLB is perfectly suited to mineral sun care formulations or make-up. In addition to these applications, MLB is used in the currently highly popular stick formulations, where it exhibits unique properties.

MLB consists of several components and, thanks to Sunjin’s processing technology, presents significant advantages compared to a formulation in which those components have been added individually. These advantages include:

a)    Increased emulsion stability
b)    Improved pigment stabilization
c)    Exceptional feel to the skin with reduced stickiness


MLB – the innovation for stick formulations

Stick formulations have existed on the market for a long time. But it was the K-Beauty trend from Korea that gave this form of cosmetic products its first real momentum. It’s well worth taking a look at the different generation of sticks:

  1. st Generation: wax sticks 
    • Good solidity and stability
    • Glossy look
    • Heavy, sticky feel to the skin
  2. nd Generation: wax sticks containing powder (e.g. silica)
    • Improved look and feel
    • Poorer transparency
  3. rd Generation: O/W sticks
    • Light texture
    • Poor solidity and stability
    • High, skin-irritating pH (9–11)
    • Rapid drying after opening

MLB is now here to develop the 4th Generation of sticks: W/O sticks. W/O sticks with MLB stand out for the following properties:

  • Fresh and light texture with up to 50% water
  • Non-sticky
  • Good stability and solidity of the stick
  • Neutral, skin-friendly pH
  • Significantly reduced water loss after opening
  • Good water resistance
