The selection and proportion of cosmetic raw materials play a vital role in the cosmetic manufacturing process, which directly determines the quality and effect of the product.

In this complex and delicate process, the use of emulsifiers has become an indispensable part.

1. The importance of cosmetic raw materials

The raw materials of cosmetics are the basis of the product. They not only determine the texture, color and fragrance of the product, but also directly affect the efficacy and use experience of the product.

When selecting raw materials, it is necessary to fully consider their functions and properties, such as antioxidant, moisturizing, whitening and other effects, while avoiding ingredients that may cause skin irritation or allergic reactions.

In addition, the safety of raw materials is also a factor that cannot be ignored. It is necessary to ensure that all raw materials comply with relevant regulatory requirements.

Taking a popular moisturizing cream as an example, its formula may contain the following key ingredients and proportions:

Base oil (such as squalane): 5-10%, provides moisturizing feeling and enhances skin barrier.

Polyols (such as glycerin, butylene glycol): 5-15%, strong water absorption and lock moisture.

Hyaluronic acid: 0.1-0.5%, deep moisturizing, increasing skin elasticity.

Natural plant extracts (such as aloe vera juice, green tea extract): 2-5%, anti-oxidation, soothing skin.

Emulsifier (such as glyceryl stearate): 1-3%, help water and oil mix to form a stable emulsion system.

Preservative (such as phenoxyethanol): 0.5-1%, prevent microbial growth.

The proportion of cosmetic raw materials is a delicate work combining science and art. It not only affects the quality and effect of the product, but also directly affects the brand image and market performance. Through continuous exploration and innovation, the cosmetics industry will continue to bring consumers a safer, more efficient and personalized product experience.

2. Application of emulsifier in cosmetics production

As an efficient mixing equipment, emulsifier plays an important role in cosmetics production.

It can mix two or more immiscible liquids and form a uniform and stable emulsion, thereby improving the texture and stability of the product.

In cosmetic formulas, water and oil are two common immiscible liquids. Through the high-speed stirring of the emulsifier, they can be fully mixed and form a delicate emulsion, improving the quality of the product and user experience.

III. Working principle and types of High Shear Emulsifier

The working principle of the emulsifier is mainly to use the shear force and centrifugal force generated by the high-speed rotating rotor to mix two or more immiscible liquids and form an emulsion.

According to different application scenarios and needs, emulsifiers can be divided into many types, such as intermittent emulsifiers, continuous emulsifiers, vacuum emulsifiers, etc.

Intermittent emulsifiers are suitable for small-scale production or laboratory use, with the characteristics of simple operation and easy cleaning;

Continuous emulsifiers are more suitable for large-scale production, which can realize continuous feeding and discharging and improve production efficiency;

Vacuum emulsifiers can mix under vacuum, reduce the generation of bubbles, and make the emulsion more delicate and stable.

IV. How to choose a suitable emulsifier

When choosing an emulsifier, you need to consider multiple factors to ensure that it can meet production needs.

First, it is necessary to clarify the type and scale of products to be produced to determine the required emulsification capacity and output.

Secondly, it is necessary to consider whether the material and structure of the emulsifier are suitable for the materials to be processed to avoid problems such as corrosion or pollution.

In addition, attention should be paid to the ease of operation and maintenance of the emulsifier to ensure the smooth progress of production.

Finally, price is also an important consideration. It is necessary to choose products with high cost performance while meeting production needs.

V. Practical Application of Emulsifier in Cosmetic Production

In actual production, emulsifiers are widely used in the preparation process of various cosmetics.

For example, in the production of skin care products such as creams and lotions, emulsifiers are used to fully mix the water phase and the oil phase to form a stable emulsion;

In the production of makeup products such as foundation liquid and eye shadow, emulsifiers are used to evenly disperse ingredients such as pigments and oils in the carrier to improve the covering power and durability of the product.

In addition, in the production of personal care products such as shampoo and shower gel, emulsifiers also play an important role, helping to achieve uniform mixing and stability of various ingredients.

The selection and proportion of cosmetic raw materials and the use of emulsifiers are crucial links in the cosmetic manufacturing process.

By scientifically and rationally selecting raw materials and proportioning schemes, combined with appropriate emulsification technology and equipment, high-quality cosmetic products can be produced to meet the diverse needs of consumers.
