Problems solved by technology

[0004] However, when caprylyl hydroxamic acid is used as a cosmetic preservative, it often faces some technical difficulties and problems: First, compared with traditional antiseptic ingredients, caprylyl hydroxamic acid has relatively weak antibacterial ability, and it is difficult to achieve a good antibacterial effect when used alone. Antibacterial effect; Second, powder caprylyl hydroxamic acid is not easy to dissolve and disperse in cosmetics, and it is difficult to achieve a balanced antibacterial state of the system
However, there is a common problem in the above preservative compositions: due to the addition of a large amount of surfactant, micelles are easy to form, thereby attracting and wrapping caprylyl hydroxamic acid, and finally reducing its antiseptic performance

Abstract

The invention belongs to the technical field of cosmetics and particularly relates to a compound preservative containing capryloyl hydroxamic acid and a preparation method thereof. The preservative comprises, by mass, 3-15% of capryloyl hydroxamic acid, 3-15% of p-hydroxyacetophenone, 2-10% of gluconic acid-delta-lactone and 60-90% of ethylhexylglycerin. The compound preservative is simple in component, safe, free of irritation and wide in application range, does not contain a surfactant, can be sufficiently dissolved and dispersed in cosmetic components and has a stable and obvious preservative effect.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a compound preservative containing caprylyl hydroxamic acid and a preparation method thereof. Background technique [0002] Cosmetics are rich in nutrients such as amino acids, proteins, collagen, vitamins, and water. While providing nutrients to the skin, they are also prone to breed bacteria, molds, and other microorganisms. In addition, most cosmetics are non-disposable products. It is easy to cause repeated pollution, resulting in a decline in the quality of cosmetics, such as discoloration of the product, swelling of the paste, damage to the emulsification, mildew spots, organic acids, odors, etc., which will bring discomfort to consumers and even damage consumers in serious cases. health. Therefore, a good antibacterial system is essential for cosmetic products. At present, the preservatives of cosmetics are mainly chemically synthesized ingredients, but amo...
