At Sanex, we believe in caring for both your skin and the environment. That’s why we’ve created a range of shower gels for sensitive skin that are largely biodegradable. Containing 99% biodegradable ingredients, these shower gels are formulated with 0% sulphates (including SLS), 0% colourants and 0% microplastics, helping to minimise the risk of skin irritation.

 

OBJECTIVE

 

To demonstrate efficacy in preventing lipid peroxidation of the skin and in eliminating/reducing its by-products.

STUDY DESIGN

Skin peroxidation in an ozone chamber

 

Exposure to 100 ppb ozone for 1 hour to induce MDA formation

Washing and rinsing

  1. Water (100 ml/s) for 2–3 s
  2. 200 μl of experimental sample for 75 s
  3. Water for 15 s

MDA extraction and measurement

  1. 500 μl ethanol and rub with a glass rod for 60 s (×2)
  2. Sample centrifugation
  3. Chemical analysis

A Pig skin obtained from an abattoir was used (Animals Technology, Inc.). MDA: methylenedianiline.

 

RESULTS

The sulphate-free cleansing gel generated lower levels of MDA (p<0.05).

The sulphate-free cleansing gel provides stronger protection

 

When the skin was exposed to ozone after washing, lower levels of lipid oxidation were observed with the sulphate-free Sanex cleansing gel (p<0.05).

CONCLUSION

 

Sulphate-free Sanex more effectively eliminated free radical by-products that damage the skin and prevented lipid oxidation when the skin was exposed to ozone or pollution.
