Dammar Gum Resin Crystals
Natural Dammar gum resin crystals obtained from Shorea trees in Indonesia (Sumatra).
White to yellowish-white translucent, globular to pear-shaped grains, irregular fragments or stalactite masses. Grade A consists of 1/2 cm to 5 cm pieces as well as about 5% resin powder.
Used in incense, varnish and other products. Commonly used in oil painting, both during the painting process and after the painting is finished. Dammar crystals are also dissolved in molten paraffin wax to make batik, to prevent the wax from cracking when it is drawn onto silk or rayon.
Damar crystals are dissolved into beeswax with pigment added to harden it in order to make encaustic paints.
Dammar resins were often used in the past to caulk ships, frequently together with pitch or bitumen.

Menthol Crystals USP/BP
Synthetic racemic menthol in crystalline form, conforming to USP and BP pharmacopoeial standards. Composed of a 1:1 mixture of D-menthol and L-menthol enantiomers, with specific optical rotation between −2° and 2°, indicating optical inactivity. These crystals are white or colorless with a characteristic peppermint aroma and mild cooling effect (~50% intensity compared to pure L-menthol). Exhibits melting points of 28 °C or 38 °C due to dual crystal forms. Very slightly soluble in water, readily soluble in ethanol, volatile oils, and other organic solvents. Used in topical analgesics, lozenges, decongestants, oral care, cosmetics, food, and industrial applications. Manufactured synthetically under GMP conditions and intended for cost-effective formulations not requiring full L-menthol potency.
