Sodium Stearyl Lactylateviola ●
TL;DR. This ingredient is primarily an anionic emulsifier and co-emulsifier, helping oil and water phases stay blended in creams, lotions, and cleansing systems. It can also improve slip, texture, and foam quality.
What does Sodium Stearyl Lactylateviola do in a cosmetic formula?
This ingredient is primarily an anionic emulsifier and co-emulsifier, helping oil and water phases stay blended in creams, lotions, and cleansing systems. It can also improve slip, texture, and foam quality.
Is Sodium Stearyl Lactylateviola clean?
From a clean-beauty perspective, this ingredient is generally well tolerated and does not carry major restricted-list friction. Like many surface-active materials, it may contribute to mild irritation in sensitive users at higher use levels, especially near the eyes.
Is Sodium Stearyl Lactylateviola sustainable?
This material is commonly made from lactic acid and C18 fatty feedstocks, which may be plant-derived, though palm or other vegetable-oil sourcing can be part of the supply chain. Its ester-based structure is expected to be biodegradable and it is not known for environmental persistence.
Is Sodium Stearyl Lactylateviola COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic when made from approved natural-origin inputs and compliant processing. It fits Green Chemistry reasonably well because it can use renewable feedstocks, has favorable biodegradability, and performs at low levels as a formulation stabilizer.
How does Sodium Stearyl Lactylateviola work chemically?
The molecule is an amphiphilic sodium salt with a long fatty chain and lactylate ester groups, giving it both oil affinity and water dispersibility. Typical cosmetic use is often around 0.5% to 3%, with best performance in mildly acidic to neutral emulsions and sensitivity to strong acid or alkaline hydrolysis over time.
