Key properties of the GalasterTM
biosolvent range
All GalasterTM solvents share the following properties:
1. Organic
2. Protic and Polar:
CH3 C C
H
O
O Et
OH
2. Protic and Polar:
� OH function free – Hydrogen atom able to form hydrogen bond
3. Oxygenated
� Ester alcohols
� When longer chain alcohols are used for synthesis, the solvent is more likely to be non polar
� This explains why Ethyl hexyl Lactate is not soluble in water as opposed to Ethyl lactate

Poor Standard Excellent• The contact angle shows the
ability of a liquid to wet a surface
27www.lactic.com
• The method consists of measuring the angle made by the tangent to the drop profile and the substrate
• It is considered that the wettability is good if the angle isless than 90°

Additives for solvent-based products
• As we’ve just seen, Galasters are very high polar solvents and show high solvency power with regard to polar polymers (vs. acrylic, epoxy, acetate, .... resins), their use in solvent based formulations is possible
� As co-solvents in high solid paintsAs co-solvents in resins� As co-solvents in resins
� As additives in chemical formulations
� To increase open time, to control evaporation, to slow down drying time
– (High boiling point solvent – Slow evaporation rate)� To improve the wetting properties
– (Contact angle improved on PVC, …)

Graffiti removers
Ethyl lactate has been tested in several formulations. In combination with Ethyl soyate, it’s highest efficiency has been shown for markers, lipstick, correctional fluid, spray paint on unpainted & painted smooth surfaces (non porous) and least efficiency on wood and painted concrete.

Before and after using SOYsolv® blend of Ethyl lactate, let it rest for about threeminutes, and then wipe with a scratchless scrub pad.Source: http://www.responsiblepurchasing.org/publications/Grafitti_Report.pdf
