A solid or semi-solid blend of butters, waxes and oils that melts on contact with skin.

Multi-purpose skin balm, Cuticle and elbow balm, Face balm for very dry skin, Solid perfume or travel balm
What it is
A balm contains no water: oils are thickened with waxes and butters so it holds its shape in a tin or jar. It warms and melts as it is applied, leaving a rich, protective layer on dry patches, cuticles and lips. Its small, solid format also suits travel and outdoor kits.
Suits plastic-free packs such as tins and paper tubes.
Challenges
Can soften or melt in hot transport and storage.
Butters can turn grainy if cooling is uncontrolled.
Heavy feel limits daytime face use.
