Embodiment 1

[0054] The polymer supramolecular system containing both negative charges and hydrophobic groups in this embodiment is made from the following raw materials in mass percentage:

[0055]

[0056] The aforementioned supramolecular polymers can be prepared in an organic medium (usually tert-butanol or tert-butanol solution) by a solution method. In this method, the monomer and crosslinker are first dissolved in an organic medium, followed by the addition of the initiator. The resulting polymer solution was continuously stirred until the reaction was complete or the reaction reached a minimum residual monomer concentration. If the medium is an organic solvent with a low boiling point, the reaction can be carried out under condensing reflux during the continuous stirring stage. After the reaction is complete, the low-boiling medium is removed under low pressure.

[0057] Such as figure 1 As shown, the supramolecular polymer exhibited a very stable thickening and stabilizing a...

Embodiment 2

[0065] This embodiment is a refreshing and fluffy shampoo for hair care products containing the supramolecular polymer of Embodiment 1, including the following raw materials in mass percentage:

[0066]

Embodiment 3

[0068] This example is a skin care product night moisturizing night cream containing the supramolecular polymer of Example 1, the composition of which is shown in Table 1 below. Wherein the total weight of all raw materials is 100%. The weight ratio is the percentage of each raw material in the total weight.

[0069] Table 1

[0070]

[0071] In Table 1, "cetearyl alcohol in phase A; dihexadecyl phosphoric acid; ceteth-10 phosphate" is Clariant's Natural Emulsifier HE20, "Phenoxyethanol; Ethylhexylglycerin" in Phase E is Schülke PE 9010.

[0072] step:

[0073] Heat phases A and B to 75°C separately. Add phase A to phase B with stirring, then mix on the homogenizer at 7000 rpm for 30 seconds. After cooling to 65°C, add phase C and mix well. Phase D was added to adjust the pH to 6.5. After further cooling to 40°C, add phases E and F and mix well.

Abstract

The invention discloses a polymer supramolecular system simultaneously containing negative charges and hydrophobic groups and application of the polymer supramolecular system in skin care products, cosmetics, personal care products and biological medicine products. The polymer supramolecular system has both structural units shown as the following formulas (I) and (II) in the specification. In eachstructural unit shown as the formula (I), R1 is independently selected from H or a methyl group; in each structural unit shown as the formula (II), R1' is independently selected from H or a methyl group, R2 is independently selected from H or C12-C36 alkyl groups, and n is independently selected from an integer in a range of 0-100.

Description

technical field [0001] The invention relates to the technical fields of personal care, cosmetics and biomedicine, in particular to a polymer supramolecular system containing both negative charges and hydrophobic groups and its application in skin care products, cosmetics, personal care products and biomedical products. Background technique [0002] Supramolecules usually refer to the combination of two or more molecules relying on intermolecular interactions (such as: intermolecular hydrogen bonds, van der Waals forces, hydrophilic and hydrophobic interactions, π-π interactions, etc.) to form a complex , Organized aggregates. Traditional synthetic molecules are covalently linked molecules or macromolecules, whereas supramolecular complexes contain non-covalent linkages in the association of two or more blocks. Supramolecular systems based on non-covalent bonds are widely used in many fields including adhesives, printing, biomedicine, cosmetics, personal care and coatings (S...
