Sodium Dehydroacetate \ +/-: Yellow 5 Lake ●
TL;DR. This ingredient primarily acts as a preservative, helping control yeast, mold, and some bacteria in water-containing formulas. When the optional color component is present, it also contributes it coloration or shade adjustment.
What does Sodium Dehydroacetate \ +/-: Yellow 5 Lake do in a cosmetic formula?
This ingredient primarily acts as a preservative, helping control yeast, mold, and some bacteria in water-containing formulas. When the optional color component is present, it also contributes it coloration or shade adjustment.
Is Sodium Dehydroacetate \ +/-: Yellow 5 Lake clean?
From a clean-beauty perspective, this ingredient has a generally acceptable preservative profile at regulated use levels, with low sensitization concern compared with many stronger preservative systems. The optional color component creates more friction because synthetic colorants are often restricted or screened closely by stricter clean standards.
Is Sodium Dehydroacetate \ +/-: Yellow 5 Lake sustainable?
This material is typically synthetic rather than directly plant-derived, and it is used at low levels, which limits its formula footprint. The preservative portion is expected to have better environmental behavior than persistent silicone or fluorinated materials, while the optional insoluble color component is less aligned with biodegradability goals.
Is Sodium Dehydroacetate \ +/-: Yellow 5 Lake COSMOS-approved?
The preservative portion is permitted under COSMOS with concentration and use restrictions, so it has partial natural-standard alignment. The optional synthetic it colorant is generally not aligned with COSMOS natural or organic colorant rules, which weakens the overall Green Chemistry fit.
How does Sodium Dehydroacetate \ +/-: Yellow 5 Lake work chemically?
The molecule is a salt form of an organic heterocyclic preservative, chosen for water compatibility and antimicrobial activity that is strongest in mildly acidic systems. Typical use is low, often around 0.1% to 0.6% depending on region and formula type, and performance is commonly paired with pH control and supporting preservative boosters.
