Description

Pure natural whitening and skin tendering bath salt and preparation method thereof

Technical Field

The invention relates to the field of daily chemical articles, in particular to pure natural whitening and skin-tendering bath salt and a preparation method thereof.

Background

The main component of the traditional bath salt is sodium chloride, and essence or other chemical additives are added as auxiliary materials to be used as a cleaning product for bathing or bathing, or the bath salt is added into bath cream or a detergent to be used as a bathing product when in use, and the main effects are cleaning and exfoliating, and the traditional bath salt is used for bathing, face washing and foot bathing. The research shows that the long-term use of the bath salt can eliminate the melanin on the skin, gradually restore the skin to be fine, white, tender and elastic, and has positive effects on removing skin acnes and color spots. However, the existing bath salt components contain preservatives or chemical additives, which cause certain irritation to the skin and dependence on the chemical additives, and are not good for human health after long-term use. More importantly, the traditional bath salts have a relatively general capability of penetrating through the stratum corneum of the skin and are difficult to bring active ingredients into the dermis to play a role, so the traditional bath salts have low utilization rate of active substances and poor whitening and skin-tendering effects, and have the defects of low capability of keeping the activity of the active substances and incapability of keeping the activity for a long time.

Taraxacum mongolicum hand-Mazz (Latin name) is also called herba crotalariae albidae, herba sterculiae lychnophorae, Urtica odorata, Hualanang, etc., is a dried whole herb of perennial herb dandelion of the Compositae and various congeneric plants thereof, and is distributed around the world. Dandelion is well known for its appearance, but it is usually used as a medicine, and it has the efficacies of clearing heat and removing toxicity, resolving carbuncle and dissipating stagnation, inducing diuresis and treating stranguria, and is clinically used for treating carbuncle, pyocutaneous disease, internal carbuncle, conjunctival congestion and swelling pain, damp-heat, jaundice, difficult urination and pain, furuncle and pyogenic infections, acute mastitis, scrofula, toothache, conjunctival congestion, pharyngalgia, pulmonary abscess, intestinal abscess, damp-heat jaundice, heat stranguria and pain, acute mastitis, lymphadenitis, scrofula, furunculosis, acute conjunctivitis, cold fever, acute tonsillitis, acute bronchitis, gastritis, hepatitis, cholecystitis, urinary tract infection, and the like. It is hardly used in the fields of bath salt and bath.

The dendrobium officinale is a traditional and rare Chinese medicinal material in China, has unique efficacies of tonifying stomach, promoting fluid production, nourishing yin, clearing heat and the like, is used for treating diseases such as chronic atrophic gastritis, hypertension, diabetes, tumor and the like, and has the effects of nourishing yin, moistening lung, nourishing stomach, promoting fluid production, improving eyesight, clearing heat, enhancing immunity, resisting aging and the like. The dendrobium officinale contains a large amount of amino acids and other nutrient substances, is a good nutrient substance source, and is beneficial to respiratory diseases, diabetes, chronic hepatitis, chronic gastritis and the like. More particularly, the Chinese medicinal composition has the most remarkable effects of relieving depression, enabling people to have a clear mood, and relieving symptoms such as high mental stress, fatigue, dysphoria, depression and the like. Modern people have high working pressure, much remuneration and irregular diet and life, and particularly under the condition of hot weather, people are easy to have dysphoria, depression, hypodynamia, unsmooth defecate, poor complexion and the like, and the dendrobium officinale can well improve the symptoms. At present, the method is rarely used in the fields of bath salt and bath.

The dead sea is rich in various mineral substances beneficial to human bodies, wherein the mineral substances comprise potassium, magnesium, bromide, sodium, zinc, sulfur, chloride and trace elements, can play a role in sterilizing and diminishing inflammation, can regenerate cells, can treat skin itch, bacterial infection, redness, tinea, and the like, can drive the mineral substances to be transported to the deep layer of the skin through strong permeability in addition to treating rheumatoid arthritis and muscle pain, can promote blood circulation, can eliminate fatigue, relax nervous tension, soothe, relieve pain, supplement the mineral substances required by the skin, and can whiten, resist the sun and tighten the skin.

Generally, the salt itself causes some irritation to the skin, especially in weak, sensitive areas of the skin, such as the facial skin. Therefore, it is desirable that the bath salt not only does not damage the skin and human body, but also exhibits excellent cleansing, spot-removing, whitening and moisturizing effects.

Disclosure of Invention

Aiming at the problems in the prior art, the invention aims to provide a pure natural whitening and skin-tendering bath salt.

The invention also aims to provide a preparation method of the pure natural whitening and skin-tendering bath salt.

Further, the invention also aims to provide a use method of the pure natural whitening and skin-tendering bath salt.

The invention adopts the following technical scheme:

the pure natural whitening and skin tendering bath salt comprises the following raw materials in parts by weight:

optionally, the pure natural whitening and skin-tendering bath salt comprises the following raw materials in parts by weight:

further, the salt is obtained by directly evaporating dead sea water, and is more natural than a mode of obtaining by reprocessing lake water or sea water, and the particle size of the salt is 100-1000 meshes, such as 100-200 meshes, 200-300 meshes, 300-400 meshes, 400-500 meshes, 500-600 meshes, 600-700 meshes, 700-800 meshes, 800-900 meshes, and 900-1000 meshes.

Further, the salt comprises 20-50 parts, such as 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49 or 50 parts.

The dandelion extract contains various active ingredients, such as taraxasterol, taraxacum picrin, flavonoids, organic acids, saponins, polysaccharides, polyphenols and the like, and specifically, caffeic acid, ferulic acid, chlorogenic acid and the like, and the active ingredients are difficult to extract by a common water-alcohol system extraction method. Many of the components in dandelion extract can produce biological effects, but exert unique actions, such as scavenging active oxygen free radicals. Chlorogenic acid is generated by dandelion in the aerobic respiration process of the plant body, has the effects of resisting oxidation and promoting metabolism of the human body, and further has the effect of regulating skin vitality. Furthermore, the dandelion extract can promote the expression of hyaluronic acid synthetase, and synergistically increase the elasticity and smoothness of skin together with other components, especially, the dandelion extract enters pores to permeate deeper layers of skin through the osmosis of salt, so that the skin is moistened and whitened. In addition, the sebum secretion is excessive for oily skin, so that dirt such as dust is easily adhered to the skin, pores of the skin are easily blocked, and pruritus and inflammation are caused. The saponins and polyphenols in the dandelion extract can be more efficiently removed and the generation of oil and fat can be controlled together with the lemon extract. In addition, the ferulic acid contained in the composition can improve the quality of skin, make the skin exquisite and elastic, and also has the effects of resisting bacteria, diminishing inflammation, resisting oxidation, removing free radicals, resisting coagulation and the like, thereby protecting the skin of a body.

Specifically, the dandelion is cleaned, the flowers can be removed, the dandelion is dried in the sun and then crushed into 50-200 meshes (such as 50-60 meshes, 60-70 meshes, 70-80 meshes, 80-90 meshes, 90-100 meshes, 100-120 meshes, 120-150 meshes, 150-180 meshes and 180-200 meshes) of powder by using a crushing device, and the powder is subjected to supercritical CO₂The extraction process extracts the powder.
