Application of hinokitiol

Hinokitiol has been used in the production of shower gel, cosmetics, medicine, agriculture, and other products. In addition, hinokitiol has outstanding effects in the prevention and control of soil-borne diseases.

1. Skin and Oral Care

β-thujaplicin is used in a range of consumer products for skin care, such as soaps, body lotions, eyelid cleansers, shampoos and hair tonics. Oral care such as toothpaste, and breath sprays.

Very good bactericidal and antibacterial effects. For example, Staphylococcus aureus causes skin carbuncle, acne bacillus causes acne, Malassezia that causes folliculitis and dandruff, Candida albicans that causes fungal vaginitis, and other microorganisms have antibacterial effects. And long-term use will not produce drug resistance.

Hinokitiol has an astringent effect, can promote cell metabolism, has an anti-acne bacillus effect, and can be used in anti-acne products. Moreover, juniper alcohol can absorb ultraviolet rays and play a whitening effect.

Anti-inflammatory effect. Because of its phenolic ketone structure can increase the permeability of blood vessels, it can be used for skin inflammation. After clinical tests, hinokitiol can improve the eczema of most patients, and reduce or disappear the itching.

In addition, juniper alcohol also has the functions of oral antibacterial, halitosis removal, lipase activity inhibition, and weight loss.

2. Insect repellent

The inhibitory effect of hinokitiol on termites that destroy crops was found. It has also been shown to be effective against certain mites (Dermatophex farinae, Tyrophagous spp.) and mosquito larvae (Aedes aegypti, Culex papillose).

3. Food preservatives

In experimental studies, hinokitiol has been shown to combat botrytis cinerea, a necrotic fungus that causes botrytis cinerea in many plant species. Hinokitiol can inhibit food browning by inhibiting browning enzymes, especially inhibiting tyrosinase and other polyphenol oxidases by chelating copper ions. Therefore, hinokitiol is used as a shelf-life extender in food packaging.

4. Wood preservatives

Hinokitiol is found in the heartwood of naturally durable trees belonging to the Cupressaceae family. Due to their fungicidal, insecticidal, and insecticidal activities, these compounds make wood naturally resistant to decay and pests. Therefore hinokitiol has been suggested as a wood preservative.
