CN201120386282.5 reports a very simple preparation technique for DIPENTENE hard capsule formulations. The core of this technique is to directly infuse DIPENTENE into the capsule shell. After sealing with a capsule cap, the capsule body is coated at a relatively low temperature, and the junction of the capsule cap and capsule body is sealed with adhesive tape. This technique is also applicable to mixed solutions of DIPENTENE and its isomers, as well as mixed solutions of DIPENTENE and other substances, such as a mixture of DIPENTENE and turpentine oil. This technique is also applicable to current methods that involve adding limonene to a solid carrier (e.g., starch) and then filling the limonene-containing solid into hard capsules, such as modifying the stability of currently marketed limonene capsules. |

| Hazard Information | Back Directory | [Description]
dl-Limonene has a pleasant, lemon-like odor free from campho raceous and turpentine-like notes. The most important and wide spread terpene; it is known in the d- and ι- optically active forms and in the optically inactive dl-iovm (known as dipentene); it has
been reported found in more than 300 essential oils in amounts
ranging from 90 - 95% (lemon, orange, mandarin) to as low as
1% (palmarosa); the most widespread form is the d-limonene,
followed by the racemic form, and then ι-limonene. | [Definition]
ChEBI: Limonene is a monoterpene that is cyclohex-1-ene substituted by a methyl group at position 1 and a prop-1-en-2-yl group at position 4 respectively. It has a role as a human metabolite. It is a cycloalkene and a p-menthadiene. |
