Alpha olefin sulfonate (AOS)
01 / THE IDEA

AOS can contribute to cleaning systems with specific foam and performance goals.

02 / EXPLAINER

The alpha olefin sulfonate family

AOS describes a family of anionic surfactants used in selected liquid cleaners. Supply grades can vary in chain-length distribution, active concentration and mixture composition. The abbreviation does not guarantee identical performance across suppliers. AOS can contribute to foam, wetting and cleaning within a specific system, but outcomes require testing.

03 / EXPLAINER

Compare on a scientific basis

Match actual surfactant activity when comparing AOS with a reference system. Test representative grease removal, foam and rinsing at different water hardness levels. Examine supplier quality and compatibility with fragrance, salts, thickeners and pack. Select the grade for measurable benefit at suitable cost and safety, not because it is generically described as stronger than another material.

ILLUSTRATIVE CASE STUDY

How would this be tested?

Compare an AOS-containing dishwashing base with a reference at equivalent active levels. Assess grease removal, foam and rinsing in defined water, then repeat at another hardness or soil type to examine limits of the result. Follow packaged samples for clarity and viscosity after storage. If foam improves without additional grease removal, report these as distinct observations rather than calling one ingredient universally stronger.

Practical evaluation checklist

01

Compare supply grades and active content.

02

Test under intended-use conditions.

03

Monitor interactions with additives and fragrance.
