Chemical raw materials are the foundation of cosmetics, providing core functions such as cleansing, moisturizing, and beautifying. They are present throughout the range of oil-based bases (oils, waxes) to powder-based products (foundation, eyeshadow) and various functional auxiliary ingredients (solvents, emulsifiers, preservatives, etc.), and are indispensable substances for achieving various skincare and makeup effects.Essentially , they are everyday chemical products. 

1. Oily base ingredients : These form the main framework of the product, such as animal and vegetable oils, paraffin wax, petrolatum, and high-grade fatty acids, providing a moisturizing feel.

2. Powdered ingredients , such as talc, mica, and titanium dioxide, are used in foundations, loose powders, and eyeshadows to provide concealing and matte finishes.

3. Solvents : Water is the primary solvent, while alcohols (ethanol), ketones, etc., are used to dissolve other components and adjust the texture.

4. Surfactants : Used in cleaning products (such as facial cleansers) to generate foam and emulsify oil and dirt, such as soap-based and amino acid surfactants.

5. Moisturizers , such as glycerin, hyaluronic acid, and butylene glycol, can absorb or lock in moisture from the air.

6. Preservatives : prevent the growth of microorganisms and extend the shelf life of products, such as parabens.

7. Emulsifiers : help oil and water mix to form an emulsion (cream), such as polyglycerol-3-methylglucose distearate.

8. Fragrances and flavors : provide pleasant scents and improve the user experience.

9. Functional additives :

• Antioxidants : prevent components from oxidizing (such as vitamin E).

• Whitening agents : such as vitamin C and its derivatives, niacinamide.

• Anti-aging ingredients : such as retinol (vitamin A) and peptides.

• Soothing ingredients : such as chamomile extract and panthenol (B5).

• Colorants : Used in makeup to provide color. 

• Basic functions : cleansing (surfactants), moisturizing (humectants), nourishing (oils/waxes).

• Enhancement and beautification : Powdered ingredients (foundation, loose powder) and colorants (lipstick, eyeshadow) alter skin tone and appearance.

• Protective effects : Sunscreens protect against ultraviolet rays, and antioxidants fight free radicals.

• Special effects : Whitening, anti-aging, and repairing active ingredients (such as niacinamide and peptides).

• Texture and stability : Emulsifiers, thickeners, stabilizers, etc. ensure the product's good skin feel and stability.
