Description

Cleansing cream and preparation method thereof

The invention relates to a cleansing cream, in particular to a weakly acidic amino acid cleansing cream and a preparation method thereof.

Due to the increasingly developed industry, the damage to the living environment is also becoming increasingly serious. Under this situation, haze, ultraviolet rays and computer radiation have caused great damage to the skin. Nowadays, consumers in this environment have caused consumers to have dry and sensitive skin. The situation is increasing day by day, so it is especially important to choose mild and moisturizing cleaning products. Generally, the normal skin surface is weakly acidic, the pH is between 4.8 and 6.5, and the largest original composition of the skin stratum corneum is a large number of amino acids. Because of this, it is urgent for existing consumers to seek a weakly acidic amino acid cleansing cream. Demand.

When consumers use existing cleaning products, they often cause excessive skin exfoliation, washing away moisturizing ingredients and oil complexes that normally stay on the skin surface, causing dry, itchy and sensitive skin. In addition, the existing amino acid cleansing cream also has the following problems in the production process: the ambient temperature of the semi-finished product storage room in the workshop cannot be kept uniform, and the semi-finished product can not be cooled and left to stand for a long time, resulting in long crystallization time, and the viscosity and hardness of the internal materials. Difficult control issues.

The invention provides a weakly acidic amino acid cleansing cream and a preparation method thereof. By combining an amino acid compound surfactant and an active compound composition of a sebum repair composition, a skin cleansing product for long-term use of easily sensitive and dry skin is prepared. . The cleansing cream of the present invention contains a sebum repairing composition, which can repair the damaged sebum layer of the skin. It is different from ordinary detergents and does not leave the normal moisture on the skin after washing the skin. Wash off with oil and even have the ability to replenish, which in turn produces a long-lasting moisturizing effect. In addition, because the sebum repair composition is added, the cleansing cream of the present invention can further enhance the skin's hydration and binding ability, resist the pollution of the external environment, and provide a significant moisturizing and anti-allergic effect.

The cleansing cream according to an embodiment of the present invention includes: 20.0 to 25.0 wt% of sodium lauryl sarcosinate, 5.0 to 7.0 wt% of sodium cocoate isethionate, and 1.5 to 2.5 wt% of cocoyl amino Sodium propionate, one of sebum repairing composition of 1.5 to 7.0 wt%, butanediol of 15.0 to 18.0 wt%, methylpropanediol of 3.0 to 5.0 wt%, diglycerol of 3.0 to 5.0 wt%, 1.5 to 2.5 wt% glycerol isostearate, 1.5-2.5 wt% polyglyceryl-10 distearate, 0.3-0.5 wt% hydrogenated shea butter, 1.0-2.0 wt% stearic acid, 0.1-0.2 wt% of colloidal silver, the rest is refined water. Wherein, the sebum repairing composition includes polyquaternium-51 and Cladophora starfish extract.

Preferably, the weight percentage of the polyquaternary ammonium salt-51 is from 0.5 to 2.0 wt%, and the weight percentage of the starfish Cladosporium extract is from 1.0 to 5.0 wt%.

Preferably, the weight percentage of the sebum repair composition is 3.0 to 5.0 wt%.

Preferably, the weight percentage of sodium laurate sodium glutamate is 25.0 wt%, the weight percentage of sodium cocoyl isethionate is 6.0 weight%, and the weight percentage of sodium cocoyl aminopropionate is 2.0 wt%, polyquaternium-51 weight percentage of 1.5 wt%, starfish Cladospira extract weight percentage of 2.5 wt%, butanediol weight percentage of 18.0 wt% , 5.0% by weight of methyl propylene glycol, 3.0% by weight of diglycerol, 1.6% by weight of glyceryl isostearate, and polyglyceryl-10 distearate The weight percentage of the ester is 1.6% by weight, the weight percentage of the polyglycerol-10 distearate is 2.2% by weight, the weight percentage of the hydrogenated shea butter is 0.4% by weight, and the weight percentage of stearic acid It is 1.0 wt%, the weight percentage of colloidal silver is 0.2 wt%, and the weight percentage of purified water is 31.6 wt%.

In the cleansing cream of the present invention, polyquaternium-51 and cladosiphon novae-caledoniae extract are added as a sebum repair composition in the formula, which can effectively solve the skin caused by consumers when using cleansing products The phenomenon of excessive exfoliation will wash away the moisturizing ingredients and oil complexes that normally stay on the skin surface, causing the skin to become dry, itchy and sensitive. The unique phospholipid polymer of the sebum repair composition will gather water, which has the same role as lipids between cells, and can prevent skin moisture from evaporating. Because the polyquaternium-51 in the composition has a unique lipophilic and hydrophilic group, Structure, after repeated rinsing with water, the lipophilic group can still stay on the skin, so that the skin does not dry out and reduce skin irritation. The cladosiphon novae-caledoniae extract in the composition has an inhibitory effect. The ability of hyaluronidase activity is compared with the anti-allergic drug (tryptophan), and the anti-allergic effect is the same as that of tryptophan. In addition, the extract of C. starfish contains fucoidan with a high molecular weight, which is effective in preventing dry skin and repairing inter-sebum lipids. Colloidal silver's main function is to replace traditional chemically synthesized preservatives. For already irritated and sensitive skin, traditional chemically synthesized preservatives can cause irritation, while colloidal silver can effectively avoid the above problems.

As an amino acid surfactant, sodium lauryl glutamate not only has good degradability, antibacterial, safety, and non-allergenic properties, but also has good water solubility as an amphoteric surfactant due to its special structure. It has many excellent properties such as strong salt resistance and pH response. However, when butanediol is used as a solvent, sodium lauryl glutamate is easily crystallized. Therefore, the skin cleansing cream of the present invention can effectively solve the above problems by using a specific amount of methyl propylene glycol as a co-solvent.

The cleansing cream of the present invention not only does not damage the normal pH value of the skin while cleaning the skin, but also can be used on sensitive skin, and only a small amount can generate rich and fine foam, which can save the user's consumption. In addition, the long-term use of the user can enhance the original hydration and binding ability of the skin, and then gradually form a layer of skin protection film, making the skin not tight and irritating, and further improving the skin's ability to resist external damage.
