The invention aims to provide the hair essence production formula, various components with the effects of enhancing hair quality and improving scalp health are accurately proportioned, meanwhile, the synergistic effect is shown in the aspect of activating the activity of tyrosinase, and the prepared essence can effectively increase the black hair rate and has an excellent effect of turning white hair into black.

The utility model provides a hot air type hair straightener which comprises a main machine, a main clamping piece and an auxiliary clamping piece which can be clamped with each other are arranged on the main machine, a first clamping block is arranged on the main clamping piece, and a second clamping block corresponding to the first clamping block is arranged on the auxiliary clamping piece. When the main clamping piece and the auxiliary clamping piece are clamped with each other, the first clamping block and the second clamping block are attached to each other to be used for clamping hair, an air outlet located in the front side of the first clamping block is formed in the main clamping piece, and a hot air generating device capable of generating hot air and blowing the hot air out of the air outlet is arranged in the main machine. The utility model aims to overcome the defects in the prior art, and provides the hot air type hair straightener which not only can achieve a hair straightening effect, but also can better protect hair.

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.
