Abstract
The invention provides a mild amino acid cleansing cream and a preparation method thereof, and the mild amino acid cleansing cream comprises the following raw materials in parts by weight: 15 to 35 parts of N-lauroyl sodium glutamate, 10 to 40 parts of polyhydric alcohol, 1 to 10 parts of methyl cocoyl sodium taurate, 2 to 10 parts of sodium glutamate, 1 to 5 parts of polyethylene glycol, 1 to 5 parts of thickening agent, 1 to 5 parts of fatty acid, 1 to 5 parts of ethylene glycol distearate, 1 to 5 parts of polyglycerol-10 laurate, 0.1 to 1 part of PEG-120 methyl glucose dioleate, 0.1 to 1 part of tocopherol acetate, 0.1 to 0.5 part of chelating agent and 10 to 70 parts of water. The amino acid facial cleanser disclosed by the invention is fine and smooth in cream body, smooth and rich in foam, excellent in stability, mild in use, safe and non-irritant, suitable for various skin types and strong in cleaning performance, and the pH value is 5.3-5.8 and is close to the pH value of human skin.
Description
Technical Field
The invention relates to the technical field of cosmetics, in particular to a mild amino acid facial cleansing cream and a preparation method thereof.
Background

Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention.
This invention may, however, be embodied in many different forms than those specifically described herein, and it will be apparent to those skilled in the art that many more modifications are possible without departing from the spirit and scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In case of conflict, the present specification, including definitions, will control.
The term as used herein:
"by 8230; \ 8230; preparation" is synonymous with "comprising". As used herein, the terms "comprises," "comprising," "includes," "including," "has," "having," "contains" or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.
The conjunction "consisting of 823070, 8230composition" excludes any unspecified elements, steps or components. If used in a claim, the phrase is intended to claim as closed, meaning that it does not contain materials other than those described, except for the conventional impurities associated therewith. When the phrase "consisting of 8230' \8230"; composition "appears in a clause of the subject matter of the claims and not immediately after the subject matter, it defines only the elements described in the clause; other elements are not excluded from the claims as a whole.
When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or range defined by a list of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when a range of "1 to 5" is disclosed, the described range should be interpreted to include the ranges "1 to 4," "1 to 3," "1 to 2 and 4 to 5," "1 to 3 and 5," and the like. When a range of values is described herein, unless otherwise specified, the range is intended to include the endpoints thereof, and all integers and fractions within the range.
In these examples, the parts and percentages are by mass unless otherwise indicated.
"part by mass" means a basic unit of measure indicating a mass ratio of a plurality of components, and 1 part may represent an arbitrary unit mass, for example, 1g or 2.689 g. If we say that the part by mass of the component A is a part by mass and the part by mass of the component B is B part by mass, the ratio of the part by mass of the component A to the part by mass of the component B is a: b. alternatively, the mass of the A component is aK and the mass of the B component is bK (K is an arbitrary number, and represents a multiple factor). It is not to be misunderstood that the sum of the parts by mass of all the components is not limited to the limit of 100 parts, unlike the parts by mass.
"and/or" is used to indicate that one or both of the illustrated conditions may occur, e.g., a and/or B includes (a and B) and (a or B).
