Rebaudioside A ●
TL;DR. This ingredient is used primarily as a high-intensity sweetener and taste modifier in lip care, oral care, and flavored personal care products. It helps mask bitter notes from surfactants, actives, or preservatives without adding noticeable bulk.
What does Rebaudioside A do in a cosmetic formula?
This ingredient is used primarily as a high-intensity sweetener and taste modifier in lip care, oral care, and flavored personal care products. It helps mask bitter notes from surfactants, actives, or preservatives without adding noticeable bulk.
Is Rebaudioside A clean?
From a clean-beauty perspective, it is generally low-irritation and not a common allergen in topical or oral-care use. It has little restricted-list friction, although formulators still check purity and residual processing aids from the supplier.
Is Rebaudioside A sustainable?
This material is plant-derived from cultivated leaf biomass and is used at very low levels, which limits formula-level resource demand. It is expected to have a favorable biodegradation profile compared with persistent synthetic sweeteners, with the main sustainability variables coming from agriculture, extraction, and purification practices.
Is Rebaudioside A COSMOS-approved?
It can align with COSMOS-natural and COSMOS-organic frameworks when made through approved extraction and purification processes, with certification depending on supplier documentation. Its Green Chemistry fit is strong when sourced from renewable feedstock, processed with acceptable solvents, and used at low effective concentrations.
How does Rebaudioside A work chemically?
The molecule is a highly glycosylated diterpene derivative, which explains its strong sweetness intensity and good water compatibility. Typical use levels are often in the low hundredths to low tenths of a percent, and it is generally stable across the mildly acidic to neutral pH range common in oral care and lip products.
