Question 1

What does Psidium Guava Oil do in a cosmetic formula?

Accepted Answer

This ingredient is an emollient and skin-conditioning oil that helps soften skin, reduce transepidermal water loss, and support a smoother feel. It can also act as a carrier for oil-soluble extracts and actives.

Question 2

Is Psidium Guava Oil clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well tolerated and does not carry common restricted-list concerns. Like many unsaturated plant oils, it can become more irritating if it oxidizes, so freshness, packaging, and antioxidant support matter.

Question 3

Is Psidium Guava Oil sustainable?

Accepted Answer

This material is plant-derived and can come from fruit seed streams that would otherwise have limited use, which supports good sourcing efficiency. It is readily biodegradable, with overall impact shaped by farming practices, extraction method, and transport.

Question 4

Is Psidium Guava Oil COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic when sourced and processed according to the standard, especially through physical extraction and approved refining steps. It aligns well with Green Chemistry principles through renewable feedstock and biodegradability, while solvent-heavy extraction or intensive refining would weaken that profile.

Question 5

How does Psidium Guava Oil work chemically?

Accepted Answer

This material is a triglyceride mixture rich in unsaturated fatty acids, commonly led by linoleic acid with smaller amounts of oleic, palmitic, and stearic acids. It is typically used around 0.5% to 10% in emulsions, oils, and balms, and benefits from antioxidants such as tocopherol because high unsaturation increases oxidation sensitivity.
