HA experiments: What did we learn?

We had a live webchat at 9pm on Monday 3rd April looking back at the Hydroxyl Apatite project. Main findings Sophia What do we think we've learned from the experiments then? TBH, I feel like I know less about HA and nappies now than I thought I did before! Iona We found HA again on … Continue reading HA experiments: What did we learn?

Nappy Washing Survey – Provisional Results

Summary 3 washing/drying practices were associated with fewer reported smells (p<0.05). Higher temperature washes, hot tumble drying, more nappies in wash Hot tumble drying seems to help our respondents avoid rough nappies (p<0.05). Eco washes were associated with rough nappies. (p<0.05). A huge thank you to Emily Griffiths for designing the questionnaire and doing the … Continue reading Nappy Washing Survey – Provisional Results

Results from Cardiff Catalysis Institute (CCI)

Summary Hydroxyapatite (HA) build up was confirmed on the real world nappy samples (same nappies as Shirley Technologies tested last year). Zinc was also found evenly distributed across Nappy D A laboratory method was developed to create HA mineral build up artificially. They used several solutions – all were water with different amounts of calcium … Continue reading Results from Cardiff Catalysis Institute (CCI)
