2results about How to "Natural luster" patented technology

The invention relates to the technical field of daily chemicals, in particular to a white tomato whitening and repairing composition as well as a preparation method and application thereof. The composition comprises the following components in percentage by mass: 68-85% of jojoba oil, 10-25% of squalane and the balance of white tomato extract, wherein the total percentage is 100%. The white tomatoes are rich in colorless carotenoids (such as phytoene and tetrahydrolycopene), and have excellent antioxidant and whitening capabilities: melanin formation is inhibited, and the colorless carotenoids can inhibit tyrosinase activity, reduce melanin generation and fundamentally whiten the skin. Pigmentation caused by ultraviolet rays can be relieved through the anti-oxidation effect, and the color spots are prevented and faded. The skin color can be brightened after continuous use, so that the skin presents natural luster.

The application belongs to the field of daily chemicals, and particularly relates to a preparation method of hydrogenated castor seed oil and hair-care essence containing the hydrogenated castor seed oil. The preparation method of the hydrogenated castor seed oil comprises the following steps: S1. crushing castor seeds and sieving to obtain castor seed powder; S2. treating the castor seed powder in a low-frequency pulse electric field and intermittent microwave to obtain pretreated castor seed powder; S3. mixing the pretreated castor seed powder with a composite enzyme preparation and performing subcritical extraction to obtain an extraction liquid; S4. filtering and distilling the extraction liquid to obtain a refined filtrate; S5. mixing the refined filtrate with a palladium-carbon catalyst to obtain a semi-finished product; and S6. passing the semi-finished product through a fixed bed layer of special activated carbon to obtain a first filtrate, and filtering the first filtrate to obtain the hydrogenated castor seed oil. The hydrogenated castor seed oil used in the application can achieve the effects of high active ingredient retention rate and good oxidation stability, and can lay a foundation for the efficacy and safety of the hair-care essence prepared subsequently.
