List of Non-Recommended Chemicals April 04 2014


While the range of chemicals used in modern cosmetic and personal care products makes comprehensive
compatibility testing impossible, we have seen some problems with the following chemical
groups/product types and recommend against using them in the bottles.:

-Alcohols (Note: Alcohols may be present in many cosmetic products, including make-up remover, mouth
wash, astringent, hair serum, aftershave, and insect repellent).

-Salicylic Acid (most often used in acne treatments).

-Hair serums and treatments (detangers, relaxers, volumizers, polishers, smoothers, shine serums, etc.)
including shampoos and conditioners designed to add shine or luster to hair. Products with Argan Oil (like
Moroccan Hair oil) are definitely not recommended.

-Silicone-based lubricants.

-DEET-based insect repellent.

-Hydrogen Peroxide.

-Sterile products (Note: Even though sterile products may be fully compatible with silicone, the bottles are
not sterilized. Therefore, we don't recommend the bottles for use with fluids where sterilization may be an
issue, such as contact lens solution. This includes liquid or semi-liquid prescription medications.).

-Caustic, corrosive, or flammable products. (Many household chemicals are sold in specifically designed
plastic or glass containers specified by the manufacturer and should never be decanted. The bottles were
designed for personal care or food items you may need while traveling--not bleach, drain cleaner,
fire-starters, or hydrochloric acid.)

Recommend Testing First

The following products are compatible with our bottles in most cases. However, we've heard of problems in
some cases when using these products and recommend testing a small amount in a bottle overnight
before general use or travel.

-Personal lubricants (non-silicone based).
-Almond butter.
-Liquid sweeteners (especially Stevia).
-Essential oils.
-Sunscreen and tanning lotions.
-Skin conditioning oil formulations.
-Castille soap.

Note: You will know if your fluid is incompatible if it leaks from the bottles, changes the shape or color of
the silicone tube, evaporates from the tube, or dries up shortly after being put in the tube. Most reactions
occur overnight; this is why we recommend an overnight trial run with a new product.
