Objective Skin needs care to protect against environmental pollution. The facial skin can be protected such as cream, peel off mask and lotion facemask. This study aim is to develop the antibacterial peel-off mask gel containing St. John's Wort Oil (Hypericum perforatum oil).Methods This peel-off gel mask consists of ascorbic acid, polyvinyl alcohol (PVA, as preservative), polyethylene glycol (peg), glycrine (as plasticizer), polysorbate (tween twenty, as stabilizer), ethanol and distilled water with the addition of St. John's Wort Oil and active carbon. The peel-off physical properties (homogeneity, spreadability, viscosity, film-drying time), chemical properties (pH value, stability and antibacterial activity properties) were examined. Using of an active ingredient in peel off mask, it strengthens the role of peel off mask by opening the clogged pores. Activated carbon was added to this formulation as an active ingredient due to its adsorbent activity. In this present study, activated carbon was obtained from pinecone.Results The specific surface area (SBET) of activated carbon was found to be 536.998 m²/g. The antimicrobial activity of the St. John's Wort Oil was tested against Gram-negative bacteria (Pseudomonas aeruginosa) and Gram-positive bacteria (Staphylococcus aureus) as well as one pathogenic fungus (Candida albicans, ATCC 10231). Disc diffusion method was used to study antimicrobial activity.Conclusion The prepared peel of mask showed a good peeling feature without causing edema or irritation on the skin and that it can increase skin cleansing by removing the dirt in the skin pores.

“…8 Pine cones are a popular agricultural waste that is produced in large quantities each year and is used in a wide range of industries. 9 The morphological variation of Scots pine (Pinus sylvestris L.) is abundant, and its climatic and soil requirements are mild. It is a tree species of the northern hemisphere with significant commercial value that is found in wide parts of Eurasia with a variety of climatic conditions.…”

The development of more sustainable textile dyeing techniques includes a lot of potential in utilizing bio-based plant-derived colorants. Hemp fabric has been dyed with an aqueous extract of pine cones at various dye concentrations to produce a brownish to darker color. Agricultural waste specimens, Anatolian black pine ( Pinus nigra subsp. Pallassiana), and Scots pine ( Pinus sylvestris L.) cones were used as natural dye sources on a sustainable basis. The dyed hemp fabrics were analyzed by different analytical and technical methods such as CIE L*a*b*, high-pressure liquid chromatography–diode-array detection, and scanning electron microscopy with an energy dispersive X-ray spectrometer. The color characteristics of all the dyed fabrics were measured by a CIE L*a*b* spectrophotometer. The reversed-phase high-pressure liquid chromatography–diode-array detection method with the diode-array detection method was utilized for the identification of the components of dyes present in the dyed fabrics. Scanning electron microscopy with an energy dispersive X-ray spectrometer was used for imaging and elemental analysis of the surfaces of the dyed hemp fabrics. This work has created a novelty direct dyeing method with pine cones without using any mordants and to promote the use of agricultural waste. The fastness values of washing, rubbing, and light were assessed and contrasted. The fastness results were good in general. Washing fastness values were excellent and the same for all fabrics between 4 and 5. Rubbing fastness is also generally good and of the desired grade. The chemical compositions of hemp and pine cones, as well as the formation of dyestuff fiber, were investigated by using Fourier transform infrared analysis.
