ASSESSMENT OF PARAMETERS ASSOCIATED WITH THE SAFETY OF USING HAND DISHWASHING LIQUIDS CONTAINING BERRY SEED EXTRACTS

 

 

 

 

Key words:

hand dishwashing liquids, hydrophobic plant extracts, extracts, extraction in supercritical carbon dioxide, safety.

Summary
The study assessed the effect of hydrophobic plant extracts on the basic parameters relating to the safety of use of hand dishwashing liquids. A series of liquids differing in extract type (extract concentration: 0.5%wt) was prepared. The plant extracts selected for testing included an extract of blackberry seeds (Rubus Fruticosus CO2 Extract), an extract of strawberry seeds (Fragaria Ananassa CO2 Extract), an extract of blackcurrant seeds (Ribes Nigrum CO2 Extract), an extract of chokeberry seeds (Aronia Melanocarpa CO2 Extract) and an extract of raspberry seeds (Rubus Idaeus CO2 Extract). An extract-free liquid was used as a reference product.
The results show that the addition of plant extracts obtained under supercritical CO2 conditions to hand dishwashing liquids contributes to a significant increase in their safety of use. The process is associated with a decrease in the number of surfactant free monomers in the washing bath, which triggers a reduction in the skin irritating effect and limits the washing of protective lipids from the skin. The results indicate that berry seed extracts can be an interesting raw material for modifying the quality of liquid agents dedicated to hand dishwashing.
