Using Expired Cosmetic Ingredients: Safety and Effectiveness
Question
I have the following ingredients that have expired or are near expiry (won't be used before the expiry date):
- AminoWash
- Anti-Sweat
- hydroxyethylcellulose
- Beeswax
- TiO2 200nm
- ZnO 200nm
- Matte Silica
- Zinc PCA
- Slim Coffee
- Soy Lecithin
Which of the above ingredients can still be used after the expiry date?
Answer
Hello,
Regarding your question about using expired ingredients and potential skin hazards, based on the information provided by the staff:
All the ingredients you listed can generally still be used as usual. The primary effect of using expired ingredients is a potential reduction in effectiveness, rather than causing harm to the skin. The degree to which effectiveness decreases depends largely on how well the ingredients have been stored.
- Active ingredients such as Zinc PCA and Slim Coffee (Caffeine) might have reduced efficacy, which could result in less pronounced effects on the skin.
- Other ingredients like surfactants (e.g., AminoWash), thickeners (e.g., hydroxyethylcellulose), waxes (e.g., Beeswax), mineral sunscreens (TiO2, ZnO), absorbents (Matte Silica), and emulsifiers (Soy Lecithin) can also be used, but their intended function or effectiveness might be diminished.
The staff's response does not specify a particular time limit after the expiry date or suggest using the ingredients until their color changes. The focus is on the potential decrease in performance, influenced by storage conditions.
Thank you.
