citrus grandis peel extract

Citrus grandis peel extract is a natural oleoresin obtained from the peel of the grapefruit, Citrus grandis, a member of the Rutaceae family. This extract is recognized by its characteristic strong citrus aroma, typically described as fresh and grapefruit-like at full concentration. It is alternatively known as citrus maxima peel extract or pomelo peel extract and is referenced under synonyms such as grapefruit peel extract (citrus grandis). The extraction process involves obtaining the oleoresin from the fruit's outer peel, concentrating volatile and non-volatile compounds responsible for its organoleptic and functional properties. The compound is employed in cosmetic formulations due to its skin-conditioning and perfuming qualities. For reference, Citrus grandis peel extract is listed under controlled vocabulary identifiers such as PubChem SID 135286079. Its derivation from citrus fruit peels places it among widely studied natural additives for cosmetic and fragrance use.

Citrus grandis peel extract naturally occurs in the peel of the grapefruit, Citrus grandis, and is closely related to the pomelo species. This extract finds utility primarily in cosmetic and fragrance products owing to its astringent, toning, and skin-conditioning effects. It serves as a perfuming agent imparting a citrus scent profile and is valued for enhancing sensory appeal. Its integration into formulations is governed by safety standards including the IFRA (Global) Code of Practice, particularly concerning phototoxic components such as bergapten. Usage limitations address concentration levels to mitigate potential phototoxicity on sun-exposed skin. The extract is not recommended for flavor use. Its application spans astringents, tonics, skin-conditioning products, and perfumery, contributing functional and aromatic properties aligned with consumer preferences for natural ingredients.

The physico-chemical properties of citrus grandis peel extract are driven by its complex mixture of volatile oils and non-volatile components extracted from the grapefruit peel. It displays a pronounced citrus odor reflective of its dominant terpene and flavonoid constituents. The oleoresin nature results in a viscous, resinous texture that influences formulation handling. These properties afford solubility in typical cosmetic solvents and compatibility with various product bases. Its chemical profile includes compounds that may induce phototoxicity, necessitating careful concentration control in formulations intended for skin contact, especially on areas exposed to sunlight. The extract’s stability, aroma profile, and astringent characteristics guide its suitability for tonics and perfuming uses, while its density and molecular diversity affect dispersion and final product performance.

Phototoxicity
IFRA fragrance material specification:
	Where the bergapten (5-methoxypsoralen) content of all relevant oils present in a compound has been determined, it is recommended that for applications on areas of skin exposed to sunshine, excluding bath preparations, soaps and other products which are washed off the skin, the total level of bergapten in the consumer products should not exceed 0.0015% (15 ppm). This is equivalent to 0.0075% (75 ppm) in a fragrance compound used at 20% in the consumer product. Where the level of bergapten has not been determined by appropriate methods, the limits specified in the guidelines on individual oils should apply. In those cases, where such oils are used in combination with other phototoxic ingredients, the additive effect has to be taken into consideration and the use levels have to be reduced accordingly. The sum of the concentrations of all phototoxic fragrance ingredients, expressed in % of their recommended maximum level in the consumer product, shall not exceed 100.
Recommendation for citrus grandis peel extract flavor usage levels up to:
	not for flavor use.
