Asked by: panditze On: June 17, 2015 Product Type: Cosmetics

Question

Based on the provided information regarding the suitability of aluminum bottles for essential oils and fragrance oils, but not for acids or alkalis, and mentioning that plastic is better for mild acids like `Lactic Acid` and `glycolic acid`, please clarify which types of cosmetic ingredients are generally suitable or unsuitable for storage in aluminum bottles. Specifically, what are the considerations for oils, alcohols, and acidic substances like Lactic Acid, LHA, and Vitamin C?

Answer

Suitability of Aluminum Bottles for Various Substances

Based on the information provided and general chemical compatibility, aluminum bottles are suitable for storing oils but not for acidic or alkaline substances due to potential reactivity.

  • Substances generally suitable for aluminum bottles:

    • Tea Tree Oil
    • Other natural oils
    • Alcohol
    • Ethoxydiglycol
    • Vitamin A

  • Substances generally NOT suitable for aluminum bottles (due to acidity):

    • Lactic Acid
    • LHA (Lipohydroxy Acid)
    • Vitamin C (especially acidic forms like Ascorbic Acid)

Storing acidic substances like Lactic Acid, LHA, and Vitamin C in aluminum bottles can lead to reactions that may degrade the substance or the container. For acidic substances, plastic containers are often a more suitable choice, as mentioned in the previous reply.
