Abstract

The invention belongs to the technical field of skin care products in daily-use chemical industry, and specifically relates to macadimia nut base oil and a preparation method thereof. The preparationmethod comprises the following steps: (1) pretreatment of raw materials; (2) crushing; (3) low-temperature drying; (4) cold pressing; (5) centrifuging; (6) winterization treatment; (7) filtering; and(8) finished product obtaining. According to the invention, by adoption of a low-temperature squeezing method, no additive or solvent is left; the temperature is strictly controlled to be not higher than 60 DEG C in the whole processing process; and natural nutritional ingredients of macadimia nut oil are reserved to the maximum extent. Meanwhile, through winterization treatment, the stability ofthe nut base oil is improved, and the quality problem that suspended substances are separated out due to low temperature in the storage process is effectively avoided. The macadimia nut base oil prepared by adopting the method disclosed by the invention is clear, transparent and bright in color, has nut aroma, is mild and not greasy in texture, is non-irritant, safe and stable, has excellent moistening property and skin permeability and rich moisturizing components, and can also promote absorption of nutritional components of skin care products.

Description

technical field [0001] The invention belongs to the technical field of skin care products in daily chemical industry, and in particular relates to a macadamia nut base oil and a preparation method thereof. Background technique [0002] Base oil (base oil or carrier oil), also known as carrier oil or base oil, is a non-volatile oil extracted from the seeds, flowers, rhizomes or fruits of plants. Base oil is generally mild in nature, can lubricate the skin, can be directly used for skin massage, and is also the best base oil for diluting essential oils. Common ones are olive oil, jojoba oil, sweet almond oil, grapeseed oil, avocado oil and so on. Unilateral essential oils cannot be applied directly on the skin (except for lavender and tea tree which can be applied on a small area with a cotton swab), they must be diluted in base oil before they can be widely used on our human skin. Many base oils have their own medical effects. The minerals, vitamins, and fatty acids in plan...
