General comment
12-Hydroxy stearic acid is a saturated hydroxy fatty acid. It can be used as lubricant, in cosmetics, coatings, or in rubber production.Representativeness:
The data in this EPD is representative for 12-Hydroxy Stearic Acid (12-HSA) produced by Castor International in a single production plant in India, sold on the European market from Deurne, The Netherlands.Calculation rules:
In this study, the data flows have been modelled as realisticly as possible within the practical feasibility of the LCA practitioner. The data quality is based on the principle that the primary data used for processes, occurring at the production site, must be of higher quality than background data of other processes. The processes used in the production of 12-Hydroxy Stearic Acid are geographically representative, meaning that the production location of 12-Hydroxy Stearic Acid lies within the region for which the relevant Ecoinvent environmental records have been selected. All environmental impacts and economic flows – from sources such as resources, energy, emissions and waste – were quantified and qualified in environmental effects. The rerelease of biogenic carbon dioxide in C has been modelled to compensate for any stored carbon. All known inputs and outputs - like emissions, energy and materials – have been considered in this LCA. And in accordance with EN15804+A2, the total neglected input flows per module do not exceed 5% of energy usage or mass.
The capital goods used (reactor vats, bulk transport containers, factory buildings) have been cut-off, as their contribution to the overall impact per kg is assumed insignificant, considering the amount of kg produced during the lifetime of the factory or the amount of kg transported by a single bulk container. The reference year for the data is 2022. The chemical production process has two by-products. 96,6 % of the A1-A3 impact is allocated to the production of 12-HSA. 2,7% is allocated to the production of glycerin (glycerol). 0,7% is allocated to the production of Sodium Sulphate.Scenarios and additional technical information
Within A1-A3, 12-HSA is formed from the saponification and acidification of Hydrogenated Castor Oil. It is also transported to the factory gate in Deurne, NL. Beyond, it can be used as input for the chemical industry. It can also be used as lubricant or in the personal care product industry. Assumption is made that 34% of the oil is used as secondary fuel in a blast furnace and 66% of oil is incinerated without energy recovery at end of life. MSDS available upon request.More information:
