5. In-Depth Raw Material Analysis

5.1 Surfactant System

The core of these formulations relies on a sophisticated surfactant system:

• Fatty alcohol polyoxyethylene ether: This non-ionic surfactant is the primary cleaning agent. Its structure, typically consisting of a long hydrocarbon chain (the fatty alcohol part) connected to a polyethylene glycol chain, provides excellent detergency for both polar and non-polar soils. The polyoxyethylene chain ensures water solubility and helps in the emulsification of oily soils.
• Fatty alcohol polyoxyethylene ether (9) phosphate: This modified version of the primary surfactant includes a phosphate group, which likely contributes to its color protection properties. The phosphate group may interact with fabric fibers or dye molecules to prevent color loss during washing.
• α-Olefin sulfonate: An anionic surfactant that complements the non-ionic surfactants. It provides good foaming properties and enhances the overall cleaning performance, especially for particulate soils.
• Lauryl dimethylamine oxide: An amphoteric surfactant that remains stable across a wide pH range. It enhances foam stability, provides mildness to the formulation, and can boost cleaning performance in hard water conditions.

5.2 Builders and Sequestrants

Sodium citrate: Serves multiple functions in the formulation:

• Acts as a builder by sequestering hard water ions (calcium and magnesium), preventing them from interfering with the surfactants’ performance.
• Provides buffering capacity, helping to maintain a stable pH during the wash cycle.
• May contribute to the overall cleaning performance by helping to disperse and suspend soils.
