Soy Isoflavones ●
TL;DR. This ingredient is used as a skin-conditioning antioxidant active, usually positioned for visible firmness, tone, and photoaging support. It is added at low levels rather than as a structural emulsifier, solvent, or preservative.
What does Soy Isoflavones do in a cosmetic formula?
This ingredient is used as a skin-conditioning antioxidant active, usually positioned for visible firmness, tone, and photoaging support. It is added at low levels rather than as a structural emulsifier, solvent, or preservative.
Is Soy Isoflavones clean?
From a clean-beauty perspective, it is generally acceptable, but it carries some friction because it is biologically active and often associated with hormone-pathway discussions. It may also raise source-allergen, GMO, and solvent-residue questions depending on how the raw material is produced.
Is Soy Isoflavones sustainable?
This material is plant-derived and based on a renewable agricultural crop, but the sustainability profile depends on farming practices, traceability, pesticide use, and land-use pressure. It is not considered a persistent silicone-like material and is expected to break down more readily than many synthetic film-formers.
Is Soy Isoflavones COSMOS-approved?
It can align with COSMOS-natural when sourced from acceptable plant material and processed with approved extraction and purification methods, while COSMOS-organic status depends on certified agricultural inputs. Its Green Chemistry profile is mixed: renewable feedstock is a plus, but concentrated purification can involve solvent and energy inputs.
How does Soy Isoflavones work chemically?
The molecule family consists of polyphenolic heterocycles that can occur in sugar-bound and aglycone forms, which affects polarity, skin delivery, and formulation compatibility. It is typically used at low active levels, often around 0.01% to 0.5% active content, and is best protected from extended heat, high pH, oxygen, and light to limit discoloration or oxidative degradation.
