What type of containers should fluids, creams, and powders be kept in?

Fluids, creams, and powders should be kept in clean covered containers to ensure their safety and integrity. Covered containers protect the contents from contamination, which can occur from exposure to air, dust, and other environmental factors. Keeping these products sealed helps to maintain their effectiveness and prevents any potential spoilage or degradation that could occur when they are exposed to bacteria or other impurities.

Additionally, using clean containers is crucial to prevent cross-contamination, especially in a setting like a salon or spa where products may be shared or used on multiple clients. Covered containers also reduce the risk of spills, and they help keep the products in optimal condition, extending their shelf life.

Other options like open jars, plastic bags, and glass bottles without covers do not provide the necessary protection for these products, making them less suitable choices for proper storage. Open jars expose the contents to contaminants, while plastic bags may not adequately protect against spills or evaporation. Glass bottles without covers offer no protection against external elements, making them vulnerable to contamination as well.
