What happens if you fill suppository molds too cold?

When filling suppository molds at a temperature that is too low, the mixture tends to harden too quickly. This can lead to the formation of cracks or breakage as the suppository material cools and solidifies. The reason behind this is that the base may not have enough time to create a smooth and uniform fill, resulting in structural integrity issues.

While it is also true that filling molds at low temperatures can lead to improper filling or making the suppositories too soft if too much heat is applied, these options describe outcomes that are more related to temperature mismanagement or the characteristics of the suppository base rather than the immediate effects of using a cold mixture. Thus, the primary concern with filling molds when the mixture is too cold is the increased likelihood of cracking and breaking, which affects the overall usability and effectiveness of the suppository.
