Frequently Asked Questions
What is Sodium Stearate used for?
Sodium Stearate is used in soaps, emulsions, dispersions, and interface studies based on fatty-acid salts.
What are the main characteristics of Sodium Stearate?
Sodium Stearate has formula C18H35NaO2, CAS 822-16-2, a molar mass of 306.46 g/mol, and a 250g presentation.
How does the amphiphilic structure of Sodium Stearate support emulsification?
The hydrocarbon chain interacts with nonpolar phases, while the carboxylate group interacts with the aqueous phase. This dual affinity concentrates molecules at the interface and promotes dispersion between phases.
What quantities of Sodium Stearate are available?
Sodium Stearate is available in 250g presentations. For other quantities, recurring purchases, or larger requirements, contact the sales team to check availability and request a quotation.
How can companies and institutions purchase Sodium Stearate and request a formal quotation?
Companies, laboratories, educational institutions, and research organizations can purchase Sodium Stearate directly from LojaLab. For recurring purchases, internal approval processes, research funding, public procurement, or formal quotation requirements, contact the sales team.
