Abstract:

The antibacterial effect of anisic acid gradually highlights its advantages in non-preservative skin care products. However, its insoluble property in water greatly limits its use in cosmetics. Therefore, in the production process of cosmetics, the problem of realizing and accelerating the dissolution of anisic acid needs to be further solved. In this paper, the dissolution process and application of anisic acid in cosmetic were studied by the control variable method. The effects of the dosage of L-arginine, 1,2-hexanediol, and deionized water, their dissolution time and temperature on the dissolution process of anisic acid were investigated. The better quality ratios among the influencing factors were screened out. The anisic acid was applied as a preservative to a face cream and a lotion, and their stability and microbial challenges were tracked. The results show that the mass ratio range of anisic acid that can be completely dissolved is anisic acid:L-arginine:1,2-hexanediol:deionized water=1:(0-1.5):(5-20):(0.5-100); and the optimal quality ratio range is 1:(0.8-1.5):(5-20):(0.5-2), with the obtained solution relatively stable. The optimal dissolution temperature of anisic acid is 69-75 ℃. Under the condition of the mass ratio of L-arginine of 0~0.2, a face cream and a lotion were prepared respectively. Both products have passed 12-week stability test at -15, 25, 40 and 48 ℃. Microscopic images show that the size and distribution of the emulsion formed in the aqueous solution of the face cream and lotion cream at different temperatures for 12 weeks are uniform and have good long-term stability. The results of the microbial challenge test show that the cream can pass the level 1 preservative challenge, and the lotion can pass the level 3.

Key words: anisic acid, dissolution, process, preservative challenge
