Description

Technical Field

[0001] This invention relates to the field of facial cleanser technology, specifically to an amino acid facial cleansing mousse and its preparation method. Background Technology

[0002] Amino acid facial cleansers are facial cleansers that contain amino acid surfactants as their main cleansing ingredient. They are gentle and skin-friendly, characterized by highly effective cleansing while being gentle and low-irritant, making them suitable for children and those with sensitive skin. Amino acid facial cleansers use weakly acidic amino acid surfactants, with a pH value close to that of human skin. Since amino acids are the basic building blocks of proteins, they are gentle and skin-friendly, making them suitable not only for acne-prone skin but also for sensitive skin.

[0003] For example, the herbal amino acid facial cleansing mousse disclosed in Chinese Patent 202510335686.8 constructs a preservative-free system by adding raspberry ketone and raspberry ketone glucoside, which also has antioxidant effects; through herbal extracts, it reduces product irritation, prevents free radical damage, improves the skin's resistance, and makes the product more suitable for various skin types.

[0004] Traditional facial cleansers often contain soap bases or strong surfactants, which can damage the skin barrier with long-term use, leading to dryness, sensitivity, and other skin problems. While existing amino acid facial cleansers are generally gentler, they often suffer from insufficient foam, inadequate cleansing power, or poor moisturizing effects. Furthermore, most facial cleansers lack the ability to regulate the skin's microbiome, failing to meet the diverse needs of modern consumers for gentle cleansing, moisturizing, and a balanced microbiome. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an amino acid facial cleansing mousse and its preparation method, which has the advantages of gentle cleansing, rich and stable foam, long-lasting moisturizing and anti-inflammatory soothing. It solves the problems of existing amino acid facial cleansing products, such as difficulty in balancing cleansing power and gentleness, insufficient foam stability, short-lasting moisturizing effect, and lack of regulation function on the skin microecology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an amino acid facial cleansing mousse and its preparation method, comprising phase A raw material, phase B raw material and phase D raw material, the specific composition of each phase raw material is as follows:

[0007] Phase A raw material consists of the following components by mass percentage:

[0008] Water: 62.03-64%, as a solvent, providing a medium for dissolving and dispersing other components.

[0009] Moisturizer A1 (Butylene Glycol): 5-7%, has a moisturizing effect, helps the skin retain moisture, reduces moisture loss, and keeps the skin moist.

[0010] Cleanser A: 1-2%, comprising 96.2-97% sodium lauroyl glutamate, 2-3% water, and 0.8-1% sodium chloride. Sodium lauroyl glutamate is a mild amino acid surfactant that effectively cleanses dirt, oil, and impurities from the skin surface with minimal skin irritation.

[0011] Chelating agent (octanoyl hydroxamic acid): 0.12-0.15%, can bind with metal ions to prevent metal ions from adversely affecting the stability and performance of the product, while also helping to improve the product's shelf life and storage stability.

[0012] Moisturizer A2 (Sodium Hyaluronate): 0.1-0.15%. Sodium hyaluronate has a strong moisturizing ability, which can absorb and lock in a large amount of moisture, making the skin more hydrated and smooth, and enhancing the skin's elasticity and softness.

[0013] Phase B raw material consists of the following components by mass percentage:

[0014] Cleanser B1: 15-16%, comprising 75-78% water, 15-20% disodium cocoyl glutamate, and 5-7% sodium cocoyl glutamate. Both disodium cocoyl glutamate and sodium cocoyl glutamate are mild amino acid-based cleansers that work synergistically to enhance cleansing effectiveness while remaining gentle on the skin, making them suitable for all skin types.

[0015] Moisturizer B1: 3-4%, comprising 45-65% decyl glucoside and 45-65% water. Decyl glucoside is a natural nonionic surfactant with excellent moisturizing properties and gentleness, providing moisturizing care to the skin while cleansing, reducing dryness and tightness.

[0016] Cleanser B2 (PEG-8 caprylic / capric triglyceride): 3-4%. This cleanser can further cleanse the skin, remove oil and dirt, and has certain emulsifying properties, which helps to evenly mix the ingredients in the product.

[0017] Foaming agent (PEG-80 sorbitan lauryl ester): 1-2%, which can produce rich and fine foam, making the cleansing process more comfortable and helping the cleansing ingredients to better contact and clean the skin surface.

[0018] Cleanser B3: Sodium lauroyl aspartate 31-40% and water 60-69%. Sodium lauroyl aspartate is a gentle yet effective cleanser that penetrates deep into pores to remove dirt while maintaining the skin's moisture balance.

[0019] Surfactant: 1-2%, including 40-50% sodium cocoyl glycinate and 50-60% water. Sodium cocoyl glycinate, as a surfactant, reduces surface tension, making the product easier to spread on the skin surface, improving cleaning effect and user experience.

[0020] Moisturizer B2: 1-1.5%, comprising 45-65% hydroxyethyl urea and 45-65% water. Hydroxyethyl urea has excellent moisturizing properties, replenishing skin moisture and helping to maintain skin's moisture balance, leaving skin soft and smooth.

[0021] The D-phase feedstock consists of the following components by mass percentage:

[0022] Skin conditioning agent: 0.5-0.8%, including 3-4% field peppermint leaf extract, 10-12% golden chamomile extract, 14.5-15% purslane extract, 1-2% sophora flavescens root extract, 1.5-2.5% aloe vera extract, 7-8% geranium flower / leaf / stem extract, 18-20% butylene glycol, 10-12% glycerin, 0.3-0.5% 1,2-hexanediol, 0.5-0.6% p-hydroxyacetophenone, and 28-30% water. These plant extracts and ingredients work synergistically to provide anti-inflammatory, soothing, and calming effects, reducing skin sensitivity and discomfort while providing nourishment and hydration, promoting healthy skin.

[0023] Moisturizer D1 (1,2-hexanediol): 0.3-0.5%, has moisturizing and antibacterial effects, helps the skin retain moisture, inhibits microbial growth, and improves the stability and safety of the product.

[0024] Moisturizer D2 (ethylhexylglycerin): 0.3-0.4%, can enhance the skin's barrier function, improve the skin's moisturizing ability, reduce moisture loss, and make the skin healthier and more moisturized.

[0025] Moisturizer D3: 0.1-0.2%, comprising 50-51% water, 24-25% betaine, 10-12% sodium PCA, 5-6% sorbitol, 2-3% serine, 1-1.5% glycine, 0.3-0.4% glutamic acid, 0.1-0.2% alanine, 0.1-0.2% lysine, 0.2-0.3% arginine, 0.1-0.2% threonine, 0.1-0.2% proline, and 2.2-2.5% 1,2-hexanediol. These multiple moisturizing ingredients work together to provide comprehensive hydration and maintain the skin's moisture balance.

[0026] Emollients: 0.12-0.15%, including 95-97% royal jelly extract and 3-5% 1,2-hexanediol. Royal jelly extract is rich in various nutrients, which can moisturize the skin, make it soft and smooth, and increase its elasticity and radiance.

[0027] Skin conditioning agent: 0.1-0.2%, including 8-10% leukocyte extract, 3-5% butylene glycol, 15-18% glycerin, 0.2-0.3% p-hydroxyacetophenone, 1-2% 1,2-hexanediol, and 68-70% water. Further enhances the skin's conditioning and repair functions, promotes skin metabolism, and improves skin texture.

[0028] A method for preparing the amino acid facial cleansing mousse includes the following steps:

[0029] 1) Preparation of phase A: Water, humectant A1, detergent A, chelating agent and humectant A2 are mixed and heated to 90°C and stirred until completely dissolved;

[0030] 2) Addition of Phase B: Cool to 50℃, add the following components in sequence and stir until homogeneous:

[0031] Cleaning agent B1, moisturizer B1, cleaning agent B2, foaming agent, cleaning agent B3, surfactant, moisturizer B2;

[0032] 3) Addition of Phase D: Cool to below 45℃, then add the following components in sequence and stir until homogeneous:

[0033] Skin conditioning agents, moisturizer D1, moisturizer D2, moisturizer D3, emollients, and skin conditioning agents;

[0034] 4) Homogenization and filling: Continue stirring until completely homogeneous. After passing the inspection, filter and fill into pressurized mousse bottles.

[0035] Furthermore, when adding phase B, the stirring speed should be controlled at 300-500 rpm to ensure that the components are fully dispersed but not excessively foamed.

[0036] Furthermore, the temperature is strictly controlled below 45°C when the D phase is added to avoid deactivation of the heat-sensitive components.

[0037] Furthermore, the final product has a pH value of 5.5-6.5 and a viscosity of 2000-4000 cps, making it suitable for producing fine foam using a mousse pump.

[0038] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0039] 1. This invention contains a variety of mild amino acid-based cleansers, such as disodium cocoyl glutamate, sodium cocoyl glutamate, sodium lauroyl glutamate, and sodium lauroyl aspartate. These cleansers can penetrate deep into pores to effectively remove dirt, oil, and impurities from the skin surface. Compared to traditional facial cleansers, they are less irritating to the skin and suitable for all skin types, especially sensitive skin. The addition of PEG-80 sorbitan lauryl ester as a foaming agent produces rich and fine foam. This foam not only makes the cleansing process more comfortable but also increases the contact area between the cleansing ingredients and the skin, helping to cleanse the skin more effectively.

[0040] 2. This invention contains multiple moisturizers, forming a multi-layered moisturizing system. Butylene glycol, sodium hyaluronate, decyl glucoside, hydroxyethyl urea, 1,2-hexanediol, ethylhexylglycerin, and various components of moisturizer D3 provide moisturizing care for the skin from different angles. Some form a moisturizing film on the skin surface to prevent moisture loss; others penetrate deep into the skin to replenish moisture and keep the skin hydrated. Moisturizers such as ethylhexylglycerin can also enhance the skin's barrier function, improve its own moisturizing ability and resistance to external stimuli, making the skin healthier and more stable.

[0041] 3. This invention contains a skin conditioning agent with various plant extracts, such as field peppermint leaf extract, golden chamomile extract, purslane extract, sophora flavescens root extract, aloe vera extract, and geranium flower / leaf / stem extract. These extracts have anti-inflammatory, soothing, and calming effects, reducing skin sensitivity and discomfort, and providing excellent repair and care for skin affected by external stimuli or inherently sensitive skin. Emollients such as royal jelly extract, as well as skin conditioning agents containing leukocyte extract, are rich in various nutrients, providing nourishment to the skin, promoting skin metabolism, improving skin texture, and making the skin softer, smoother, more elastic, and radiant.
