Embodiment 1

[0023] Example 1: A cosmetic preservative, mainly composed of the following components in mass percentage: octanoyl hydroxamic acid 10%, phenethyl alcohol 40%, and methyl propylene glycol 50%.

[0024] The present invention can be used in cosmetics instead of traditional preservatives. Another feature of the present preservatives is that they are still highly effective in inhibiting bacteria in a neutral pH environment. In this environment, most other preservative substitutes are not very effective. ideal.

[0025] The application of the preservative in Example 1 in the preparation of hair conditioner is as follows:

[0026] The formula of the conditioner is as follows:

[0027] Table 1 Conditioner

[0028]

[0029]

[0030] Operation process:

[0031] 1. Heat the ingredients except TC-1214 and TC-1233 in the oil phase to 75°C for use;

[0032] 2. Add the cationic hydroxyethyl cellulose and HEC to the water phase pot and stir to disperse evenly, and heat to 70-75°C;

[0033] 3. When the w...

Embodiment 2

[0036] Example 2: Basically the same as Example 1, except that the preservative formula is 8% octanoyl hydroxamic acid, 45% phenethyl alcohol, and 47% methyl propylene glycol.

[0037] The application of the preservative in Example 2 in preparing an anhydrous formula cleansing oil is as follows:

[0038] The formula of cleansing oil is shown in Table 2:

[0039] Table 2 Cleansing oil

[0040]

[0041]

Embodiment 3

[0042] Example 3: Basically the same as Example 1, except for the preservative formula: octanoyl hydroxamic acid 12%, phenethyl alcohol 38%, methyl propylene glycol 50%.

[0043] The application of the preservative in Example 3 in preparing an emulsified system is specifically as follows:

[0044] The formula of anti-allergic moisturizing cream is as follows:

[0045] Table 3 Anti-allergy moisturizing cream

[0046]

[0047] Operation process:

[0048] ①. Accurately weigh the raw materials of phase A (oil phase), heat and stir to dissolve them, and control the temperature at 80±2℃; (Note: It is recommended to add cyclopentasiloxane before emulsification in the oil and water phases);

[0049] ②Phase B (water phase): After premixing and dispersing phase B 1 and 2, add deionized water, heat and stir until it is completely dissolved. When it reaches about 90℃, stop heating, add other ingredients of phase B and continue stirring. Until it is completely dissolved, the temperature before emuls...

Abstract

The invention discloses a broad-spectrum antibacterial cosmetic antiseptic comprising the components of, by mass: 8-12% of caprylhydroxamic acid, 38-45% of phenethyl alcohol, and 46-54% of methylpropanediol. The antiseptic provided by the invention has the advantages that: (1) the antiseptic has broad-spectrum antibacterial activity, and can effectively inhibit Gram-negative and positive bacteria, yeasts and molds; (2) the antiseptic does not contain traditional antiseptic and bactericide, and is a cosmetic-use complex system completely satisfying a concept of no antiseptic addition; and the antiseptic has low irritation and high safety; and (3) the antiseptic has good compatibility with most of cosmetic raw materials; and the antibacterial capability of the antiseptic is not affected by surfactant, proteins and Chinese herbal medicine additives in cosmetics.

Description

Technical field [0001] The invention belongs to the field of daily chemicals, and specifically relates to a broad-spectrum antibacterial cosmetic preservative and its application. Background technique [0002] Everyone has the love of beauty, and human beings have been constantly pursuing cosmetics to beautify themselves since ancient times. There are many types of cosmetics, and the quality is also uneven. At present, in order to improve the shelf life of cosmetics, preservatives are usually used. Traditional preservatives are mainly as follows: (1) Formaldehyde and formaldehyde releasers, the disadvantage is that there is potential carcinogenicity; (2) Broble, the disadvantage is that it is easy to form carcinogenic nitrosamines; (3) Organic halogen components, The disadvantage is the potential sensitization. (4) Paraben esters. The disadvantage is the potential estrogen and androgen, and related to breast cancer. The EU proposal prohibits or restricts the use of paraben este...
