This simple deodorant stick formulation base uses Sodium Stearate OP-100 V as the structurant and vegetal-derived Spectrasolv® DMDA (Dimethyl Capramide) to provide clear sticks with faint opalescence at up to 0.5% fragrance. Increased Spectrasolv® DMDA and fragrance levels reduce the stick setting temperature.

PREPARATIVE PROCEDURE
| 1 | To the main vessel, with appropriate mixing and handling capabilities, add phase A, start mixing and heat to 70°C. |
| 2 | Slowly (to prevent clumping) add phase B to phase A. |
| 3 | When the batch is crystal clear and completely free of undissolved material add phase C. |
| 4 | Correct for any water loss, and then commence very slow cooling (to prevent set up of the product on the vessel walls) with strong mixing without aeration. |
| 5 | If fragrance will be added, do so when batch is at 60°C. Continue mixing and fill product when uniform and about 3°C above the set point for the product. |
