Based on 4assessment criteria, texture and sweetness of purple sweet potato lipstick are notlike by respondents while the color and aroma are favored by respondents. The results showed that purple yaw lipstick hasstability such as lipstick top leader market and no change of color, shape and odorduring storage, lipstick have very mild irritation with score 0,00 and for hedoniclevel of purple yaw lipstick 15% concentration is not favored by respondent withpresentase value is 57,10%, Whereas purple yaw lipstick is 20% and 25% is likeby respondents with presentase value repectively is 63,75%, 66,25%. The hedonic test wasconducted on 80 respondents by assessing texture, masking, color and smell oflipstick using hedonic scale. Topics covered include functional materials ( e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.) electrochemistry and solid-state ionics ( e.g., photovoltaics, batteries, sensors, and fuel cells) nanomaterials, graphene, and nanocomposites luminescence and photocatalysis crystal-structure and defect-structure analysis novel electronics and non-crystalline solids.Benefits to authorsWe also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.Stability test method by observed the change ofcolor, shape and smell for 30 days of storage and compared with lipstick topleader market, safety test is done by assessing the emergence of irritation reactionin the form of udema and erythema on albino rabbit as much as 30 with 6treatment that is without treatment, base, topical lipstick top leader market andpurple yam lipstick concentration of 15%, 20% and 25%. Papers purely on thermodynamics or theoretical calculations ( e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional inorganic materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. 2012 – 14), divided by the number of documents in these three previous years (e.g. 2015) to documents published in three previous calendar years (e.g. CiteScore values are based on citation counts in a given year (e.g. :3.12 ℹ CiteScore:2018: 3.120CiteScore measures the average citations received per document published in this title.
