Is sodium stearoyl lactylate the same as sodium stearoyl lactylate.
Sodium stearoyl lactylate, also known as sodium stearoyl lactylate, is a sodium salt formed by the neutralization of carboxyl groups on the lactate group after the esterification of stearic acid and sodium lactate. Its HLB is about 5.1, suitable for the system.
Sodium stearoyl lactylate and sodium stearoyl lactylate are two different names for the same substance, and their chemical nature, functions, and uses are completely identical. The following is a specific analysis:
1. Differences in name and chemical essence name: Stearoyl Lactate Sodium is an alias for Sodium Stearyl Lactylate (SSL), and both have the molecular formula C ₂ ₁ H ₄ ₁ NaO ₄ (or C ₂ ₄ H ₄ ₄ O ₆ Na, with slight differences in calculation methods due to different sources), with a CAS number of 182001. Synthesis pathway: Both are generated by esterification reaction between stearic acid and lactic acid (or its sodium salt), and the final product structure is the same. two Function and application: Emulsification and thickening: As a W/O (water in oil) emulsifier with an HLB value of about 5.1, it is suitable for baking foods (such as bread and pastries) to enhance gluten elasticity and delay aging. Application areas: Widely used in flour products, dairy products, candies, seasonings, etc., with a maximum addition amount usually of 2.0 g/kg. three Industry usage habits: In the food industry, the two names are often used interchangeably. Some literature uses "sodium stearoyl lactylate" as a more detailed chemical description, while "sodium stearoyl lactylate" is a generic abbreviation. Standard annotation: Both the Chinese National Standard (GB) and the International Food Additive Code (INS 481) use "Sodium stearoyl lactate" as the official name.
The two are different names for the same substance, with no substantial difference, and do not need to be distinguished in actual use.
