Development and characterization of bio-cellulose containing indian gooseberry extracts for facial mask application
Abstract:
This research studied the development of bio-cellulose containing Indian gooseberry extract for facial mask application. Indian gooseberry from 2 varieties, viz. wild and Kaset were extracted with ethyl acetate and the obtained extracts were examined for their phenolic and tannin contents. The results found that wild Indian gooseberry had more total phenolic and tannin contents than Kaset variety, with better antioxidant and tyrosinase inhibitory properties. Therefore, wild Indian gooseberry extract was chosen for study the absorption into bio-cellulose sheets. From the absorption study of the extract into bio-cellulose, it was found that the absorption of the extract increased with the extract concentrations and immersion time. Release study of wild Indian gooseberry extract from bio-cellulose was investigated in acetate (pH 5.5) and phosphate (pH 7.4) buffer solutions in order to simulate human skin and body pH conditions. The extract could release into both pH buffer solutions in a nearly similar level. This result indicates that the extract is capable of releasing from bio-cellulose sheet under skin pH conditions. The extract released from the bio-cellulose sheets exhibited an excellent antioxidant activity when the initial concentration of ≥ 1%w/v was employed. Nevertheless, its tyrosinase inhibitory activity was poor and no resistance to S. aureus and P. acnes was observed, implying lack of skin lightening ability and anti-inflammation of acne. From this study, bio-cellulose containing wild Indian gooseberry extract has potential to further develop into facial mask products with skin anti-ageing ability.
