The 750 ml size is a practical, economical format designed for shared household use, for individuals who shower frequently, or for anyone who prefers to keep one larger bottle in the shower rather than replacing smaller ones often. It's a straightforward choice for a family bathroom or a main shower. To store it, keep the bottle in a cool, dry place away from direct sunlight and extreme heat, such as a bathroom cabinet or a shelf not directly in the shower stream. While the product is stable, consistent exposure to very high humidity and heat can potentially affect the consistency or fragrance over a very long period. Ensure the cap is closed tightly after each use to prevent water from diluting the gel inside the bottle.
