The present uses of seaweed Kappaphycus alvarezii are as human foods, cosmetics, fertilizers, and for the extraction of industrial gums, chemicals and most importantly seaweeds are rich in source of Omega-3 fatty acid. The aim of present study involves preparation of poly herbal hair oil using methanol extract of brown seaweed and the other herbal plants. The prepared herbal oil was subjected to phytochemical screening, antioxidant activity, antibacterial activity, general characterization, physical and biological evaluation. The current studym involves preparation of poly herbal hair oil using Kappaphycus alvarezii, Aloe barbadensis miller, Murrays Koenigii and Ocimum tenuiflorum. The oil was prepared according to Ayurvedic pharmacopeia. The prepared formulations are assessed for primary skin irritation test on our forearm. The above said parameters were found to be good and within the standards. All the values in the evaluation of finished K. alvarezii based herbal oil showed that they are within the acceptable limits. It is a very good attempt to establish the herbal hair oil containing methanol extracts of red seaweed and the other herbal plants. Hence, it is concluded that the oil is beneficial in maintaining good growth of hairs, turning grey hairs to black, providing protection from dandruff, and results in lustrous looking hairs.

A novel synthesis of eco-friendly bioplastic film made of chitosan extracted from crab shell is presented in the current study. Crab shell use can result in a reduction in marine waste management. The extracted chitosan has a broad variety of applications in the food industry as a food preservative due to its antibacterial function. A novel procedure for preparing chitosan from crab shells was developed. In the present study, chitosan extracted from crab shell through deproteinization, demineralization and followed by deacetylation. Characterization of extracted chitosan was done by FTIR, and SEM was used to record the photomicrograph image of extracted chitosan. The antibacterial activity of extracted chitosan was studied against Staphylococcus aureus and Escherichia coli. The bio-plastic film was synthesized using the extracted chitosan by adding glycerol as plasticizer along with citric acid, and agarose to the mixture to develop bioplastic film. FTIR vibrations patterns showed stretching of hydroxyl (O-H), amine (N-H) and carbonyl (C-O) groups which indicated the presence of chitosan. The change in the morphology of samples was followed by SEM. It is concluded that the procedure developed in the present work showed that the extracted chitosan is suitable for the preparation of ultra-thin, labile, bioplastic film with good apparent texture. The advantages of the developed product could be its biodegradability, biocompatibility, and effective use as biomedical interface.
