Question 1

What does Polysorbate 60. \ +/- CI 77499 \ do in a cosmetic formula?

Accepted Answer

This ingredient is a nonionic emulsifier and solubilizer. It helps oil and water phases combine, supports oil-in-water emulsions, and can disperse fragrance, pigments, or oily actives.

Question 2

Is Polysorbate 60. \ +/- CI 77499 \ clean?

Accepted Answer

From a clean-beauty perspective, this ingredient has friction because it is ethoxylated and can carry trace processing residues such as 1,4-dioxane if not well purified. It is generally well tolerated on skin, but many stricter clean frameworks flag this chemistry rather than its day-to-day irritation profile.

Question 3

Is Polysorbate 60. \ +/- CI 77499 \ sustainable?

Accepted Answer

This material is typically made from a mix of fatty-acid feedstocks and petrochemical-derived ethoxylation chemistry. It is not usually treated as a high-persistence ingredient, but its sourcing and manufacturing route are less aligned with renewable, low-residue formulation goals.

Question 4

Is Polysorbate 60. \ +/- CI 77499 \ COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards because ethoxylated ingredients do not fit the standard’s allowed processing rules. From a Green Chemistry view, it performs efficiently at low levels, but its petrochemical processing step and residue-control needs weaken its alignment.

Question 5

How does Polysorbate 60. \ +/- CI 77499 \ work chemically?

Accepted Answer

The molecule is a nonionic, high-HLB ester surfactant with a fatty-chain lipophilic segment and hydrophilic ether-rich chains, which makes it suited to oil-in-water emulsions. Typical use is about 0.5–5% depending on the emulsion system, and it is broadly pH tolerant but can lose performance under strongly acidic, strongly alkaline, or high-electrolyte conditions.
