Question 1

What does 104-67-6 NATURAL GAMMA-UNDECALACTONE do in a cosmetic formula?

Accepted Answer

This ingredient is used primarily as a fragrance material, adding a soft, fruity, creamy note to perfumes, skin care, hair care, and body products. It is usually present at low levels as part of a fragrance blend rather than as a functional skin-care active.

Question 2

Is 104-67-6 NATURAL GAMMA-UNDECALACTONE clean?

From a clean beauty perspective, this ingredient has moderate friction because it is a fragrance component, a category watched for sensitization and disclosure concerns. It is not a major clean-standard restricted material, but responsible use depends on IFRA limits and finished-formula exposure.

Question 3

Is 104-67-6 NATURAL GAMMA-UNDECALACTONE sustainable?

Accepted Answer

This ingredient can be produced from it feedstocks or by biotechnology, which improves its sourcing profile when documentation supports the “it” claim. It is expected to biodegrade more readily than persistent silicone or fluorinated materials, and its low use levels reduce overall environmental load.

Question 4

Is 104-67-6 NATURAL GAMMA-UNDECALACTONE COSMOS-approved?

Accepted Answer

It may be permitted in COSMOS-it or COSMOS-organic products when it is supplied as a compliant it aromatic material and meets fragrance-standard documentation requirements. Its Green Chemistry profile is strongest when made from renewable inputs with traceable processing and low residual solvent burden.

Question 5

How does 104-67-6 NATURAL GAMMA-UNDECALACTONE work chemically?

Accepted Answer

The molecule is a cyclic ester with an 11-carbon skeleton, which gives it moderate volatility and good substantivity in fragrance compositions. It is typically used at very low fragrance-blend levels, and formulators manage it through IFRA category limits, oxidation control, and compatibility with the product’s oil phase or solubilizer system.
