Question 1

What does C13-16 Isoalkane do in a cosmetic formula?

Accepted Answer

This ingredient is used as a lightweight emollient and solvent, giving formulas slip, quick spread, and a dry-touch finish. It can help dissolve oil-soluble components and reduce the greasy feel of heavier oils or waxes.

Question 2

Is C13-16 Isoalkane clean?

Accepted Answer

From a clean-beauty perspective, it is generally low in odor, low in allergen concerns, and typically well tolerated on skin. The friction is its synthetic petrochemical origin and its lack of fit with many natural-standard frameworks.

Question 3

Is C13-16 Isoalkane sustainable?

Accepted Answer

This material is typically made from nonrenewable petroleum-derived feedstocks. It is not expected to bioaccumulate strongly, but its environmental profile is less favorable than readily renewable, readily biodegradable plant-derived emollients.

Question 4

Is C13-16 Isoalkane COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic petrochemical-derived emollient. Its Green Chemistry fit is limited by nonrenewable sourcing, although it is chemically stable and can sometimes replace more persistent silicone fluids.

Question 5

How does C13-16 Isoalkane work chemically?

Accepted Answer

The material is a mixture of branched, fully saturated C13 to C16 carbon chains, making it nonpolar, water-insoluble, and resistant to oxidation. It is commonly used in anhydrous systems, emulsions, makeup, sunscreen, and hair products at low to moderate levels, often to improve spreadability, volatility balance, and sensory finish.
