The invention belongs to the technical field of
plant care
essential oil extraction, and particularly relates to sanshool delayed care
essential oil and a preparation method thereof. The invention discloses a sanshool-enriched
lipid composition which is prepared from the following components in parts by weight: 0.05 to 0.1 part of sanshool-enriched fraction, 1 to 2 parts of
solid lipid, 1 to 1.5 parts of liquid lipid, 1.5 to 2.5 parts of stable surfactant, 1 to 2 parts of cosurfactant, 3 to 5 parts of
glycerol, 0.2 to 0.5 part of soothing anti-
irritation component, 0.05 to 0.1 part of
sodium hyaluronate, 0.1 to 0.3 part of hydroxypropyl
methyl cellulose, 0.05 to 0.1 part of
antioxidant and the balance of
purified water. According to the invention, sanshool is used as a core functional factor, and through
collaborative design of supercritical extraction, molecular
distillation purification, NLC carrier encapsulation and a soothing film-forming
system, contradictions of effectiveness, mildness and the like in an existing scheme are solved, and mild desensitization, stable
controlled release, reduction of stimulation and migration risks and improvement of tolerance and action consistency are realized.
