424 results about "Propionibacterium acnes" patented technology

Cutibacterium acnes (formerly Propionibacterium acnes) is the relatively slow-growing, typically aerotolerant anaerobic, Gram-positive bacterium (rod) linked to the skin condition of acne; it can also cause chronic blepharitis and endophthalmitis, the latter particularly following intraocular surgery. Its genome has been sequenced and a study has shown several genes can generate enzymes for degrading skin and proteins that may be immunogenic (activating the immune system).

Skin care product and preparation method thereof

The invention belongs to the field of cosmetics and skin care products and discloses an acne-removing composition, a skin care product and a preparation method thereof. The acne-removing composition comprises mangosteen peel, thyme and fructus aurantii. Bacteriostatic experiments of propionibacterium acnes prove that the traditional Chinese medicine composition is good in inhibitory effect on the propionibacterium acnes, the three medicinal materials of the composition have a synergic anti-inflammation effect, and the composition is fast to become effective and good in effect. The acne-removing skin care product comprises the acne-removing composition, oldenlandia diffusa, salviae miltiorrhizae, honeysuckle stem, Chinese honey locust seed, tea tree essential oil and the like. The acne-removing skin care product does not contain ethanol and is safe and mild. Experiments prove that the skin care product is evident in acne treating effect, high in cure rate, natural and mild and capable of being used for a long time. The preparation method of the skin care product is simple to operate and suitable for large-scale production.

Acne treatment essence cream and preparing method thereof

The invention belongs to the technical field of cosmetics, and particularly relates to acne treatment essence cream and a preparing method thereof. The essence cream contains aluminum starch octenylsuccinate, salicylic acid, PCA zinc, zinc gluconate, nicotinamide, tangerine orange pericarp extract, amur corktree bark extract and retinyl palmitate. The acne treatment constituents in the essence cream are obtained through screening. The new acne treatment constituents in the essence cream can effectively restrain propionibacterium acnes. Experimental studies prove that a good acne treatment effect can be realized by adding the acne treatment constituents to the essence cream. Stability studies show that the essence cream has higher stability.

Apple enzyme as well as preparation method and application thereof

The invention discloses an apple enzyme and a preparation method. The preparation method comprises the following steps: juicing apples, uniformly mixing apple juice with pure water, adding glucose which accounts for 1-5% of the total weight of the obtained raw material mixture into the raw material mixture that the volume percentage of the apple juice is 5-20%, adjusting the pH value to 5.0-7.0, sterilizing, preparing mixed bacteria from the obtained raw material liquid and a pichia pastoris bacterial liquid and a lactobacillus plantarum bacterial liquid in a volume ratio of 1:(1-5), controlling the temperature to 25-35 DEG C, performing primary fermentation for 12-48 hours, controlling the temperature of the obtained primary fermentation solution to 25-35 DEG C by using an acetic bacterial liquid, performing secondary fermentation for 12-36 hours, and sterilizing, thereby obtaining a finished product of the apple enzyme. Compared with a finished product of natural fermentation, the finished product of the apple enzyme disclosed by the invention has a remarkable antibacterial effect on propionibacterium acnes, and the removal rate IC50 of the apple enzyme on DPPH is 0.43%.

The invention provides a preparation method of a probiotic and aloe mask, which is characterized by preparing a fermentation stock solution from aloe vera raw juice, glucose and water according to certain proportions and adding probiotics for performing co-fermentation. By setting different temperature gradients and pH gradients, after viable count, optimal fermentation conditions are determined; an aloe and probiotic fermentation solution is adopted to carry out an antibacterial test so as to determine an antibacterial effect, such as propionibacterium acnes; and meanwhile, by determining an antioxidant index, the antioxidant ability of the aloe and probiotic fermentation solution is determined, such as determination of DPPH radical scavenging ability, determination of iron ion chelating ability and determination of total reducing force. According to the product, the aloe and probiotic fermentation solution is mixed with cosmetic auxiliary materials in proportion so as to be processed into a pasty mask, and after sensory index testing, skin irritation testing and trial effect testing, the safety and functionality of the product are determined, so that the aims of skin protection and health care are achieved.
