Skin care composition

Abstract

The invention belongs to the field of skin care products, and particularly relates to a skin care composition with a skin whitening function. The skin care composition comprises, in weight percent, 1.9-18% of skin-whitening agents, 0.5-20% of moisturizing repair agents, 4-20% of penetrating additives, 0.05-0.1% of chelating agents, 0.3-0.7% of preservatives and the balance water. The skin care composition has the advantages that used raw materials are high in compatibility, components are safe, and compounding of various skin whitening components is ensured.

Description

technical field [0001] The invention belongs to the field of skin care products, and in particular relates to a skin care composition with whitening function. Background technique [0002] Existing whitening and freckle-removing skin care products mainly achieve whitening and freckle-removing effects by inhibiting tyrosinase activity, melanin production, and melanin transport. Some whitening products achieve whitening effect by adding a single whitening ingredient, and the whitening method is single, and the effect is relatively weak; while many products that use a combination of whitening ingredients to achieve whitening effects have many problems in the compatibility of raw materials, pH conditions, Insufficient consideration of temperature, dosage order, and dosage form often leads to large differences in product raw materials and high instability, which limits the applicable population. For example, adding too many macromolecular thickeners will make it difficult for whi...

Some whitening products achieve whitening effect by adding a single whitening ingredient, and the whitening method is single, and the effect is relatively weak; while many products that use a combination of whitening ingredients to achieve whitening effects have many problems in the compatibility of raw materials, pH conditions, Insufficient consideration of temperature, dosage order, and dosage form often leads to large differences in product raw materials and high instability, which limits the applicable population. For example, adding too many macromolecular thickeners will make it difficult for whitening ingredients to penetrate into the skin. The bottom layer affects the whitening effect; some whitening products use vitamin C magnesium phosphate and vitamin C together, but the applicable pH conditions of these two raw materials are different. If they are used together, the efficacy of the raw materials will be weakened, and the compounding will not be achieved. synergistic effect
