• The concentration of Mineral Paraffins was highly variable in fat tissue and breast milk samples.
• The concentration of Mineral Paraffins sank between day 4 and day 20.
Summary Of Results
• Other studies revealed that the concentration of Mineral Paraffins is higher at the beginning of the breast feeding process than towards the end – this could be a hint, that the local deposit of Mineral Paraffins is emptied during breast feeding.
• Mineral Paraffins in all samples showed nearly identical composition. No cosmetic product or food with the composition found in the human samples is known to the author.
• Selective resorption in the intestines or selective accumulation of Mineral Paraffins in human fat tissue seems highly probable, but can not be proved with the findings in this research.
So, should we worry?
Weight 3500 g
Daily Milk 150 mL/kg bw
Fat in Milk 3.6 %
Days 4 – 11 pp
Concentration of Mineral Paraffins in Breast Milk (Day 4 )
40 mg/kg
Body Fat Mass (approx. 4 % of bw) 105 g
A Real Baby: Sophia
Milk in 7 days 7 d * 3500 g * 150 mL/kg bw = 3675 mL
Fat in breast milk 3675 mL * 0.04 = 132.3 g
Mineral paraffins in milk
132.3 g * 40 mg/kg = 5.88 mg
Mineral paraffins ingested during 7 days shortly after birth/kg body fat
(132.3 g * 40 mg/kg)/0.105 kg = 50.4 mg/kg
What Does Sophia Ingest?
What To Do Next?
• Limit the resorption of mineral paraffins for adults, children and especially for breast fed babies
• Make breastfeeding mothers aware of products containing mineral paraffins (eg. Paraffinum liquidum, cera microcristallina, petrolatum, vaseline)
• Rethink the limits of the EU concerning the usage of mineral paraffins and related substances in food, food processing facilities and cosmetic products
• Conduct further research on the influence of the ingestion and accumulation of mineral paraffins in humans.
• Conduct further research on the resorption and accumulation mechanisms probably found in this research.
• Research the contamination of the male population to exclude gender specific effects (eg. Usage of cosmetics). Major abdominal surgeries may present viable opportunities.
• Measurement of absolute body fat mass would be helpful in interpreting the results.
What To Do Next?
