Other comments :
Dipentene 38 Perf is a blend of several components derived from D-Limonene in the following proportions:
D-Limonene (34 - 47%)
Alpha-Terpinene (11 - 27%)
Gamma-Terpinene (3 - 13%)
Terpinolene (9 - 15%)
''Dipentene '' is also the name given to the racemic mixture of D-Limonene and L-limonene, be careful not to confuse the names!
Regulations & IFRA
Allergens :
This ingredient is classified as an allergen under European Regulation 2023/1545, dated August 26, 2023.
Its presence must therefore be declared on product labels when it exceeds 0.001% in leave-on products and 0.01% in rinse-off products. Each material must exhibit a peroxide index lower than 20 mmol/L in order to meet regulatory requirements.
IFRA 51th :
This ingredient is restricted by the 51th amendment

Specified ingredients: notes
Oxidation products of Limonene, especially hydroperoxides, have been demonstrated to be potent sensitizers. d-, l- and dl-Limonene and natural products containing substantial amounts of it, should only be used when the level of (hydro)peroxides is kept to the lowest practical level, for instance by adding antioxidants at the time of production. The addition of 0.1% BHT or α-Tocopherol for example has shown great efficiency. Such products should have a peroxide value of less than 20 millimoles per liter, determined according to the IFRA analytical method for the determination of the peroxide value, which can be downloaded from the IFRA website (www.ifrafragrance.org).
