Conclusion
Hydroxypropyl cellulose is worth keeping in perspective if you eat many diet foods or processed products containing modified fibres. Derived from purified plant fibres, it passes through the body as insoluble dietary fibre and is confirmed safe by EFSA at authorised levels. For most shoppers, hydroxypropyl cellulose is a bounded concern.
