Embodiment A1～A5

[0019] Embodiments A1-A5: Prepare emulsions with a viscosity of about 5000 cP, and investigate how many parts of oil can be emulsified by 1 wt% rape amidopropyl dimethylamine by changing the amount of oil (taking triheptan as an example), embodiment A1 The formula of ~A5 is detailed in Table 1;

Embodiment A6～A11

[0020] Examples A6-A11: Emulsions with a viscosity of about 5000 cP were prepared, and the emulsification ability of rape amidopropyl dimethylamine to different types of oils was investigated by selecting different types of oils. The formulas of Examples A6-A11 are shown in Table 2;

[0021] Observe the uniformity of the emulsified particle size of the emulsified body under a microscope, and observe whether there is stratification after centrifuging at 3000rpm for 30 minutes:

[0022] (1) After the emulsions of Examples A1 and A2 are centrifuged, they are still in a homogeneous state, without delamination, and the particle size distribution is uniform under a microscope; after the emulsions of Examples A3 are centrifuged, fine stratification occurs at the bottom, and in Examples A4 and A2 The emulsification body of A5 has obvious layering phenomenon; the results show that 1wt% rape amidopropyl dimethylamine can emulsify 25wt% polar oil triheptane, showing a very strong emulsify...

Embodiment B

[0025] In formula 669-058B, 1.5wt% rape amidopropyl dimethylamine was added as an emulsifier, and the prepared emulsion was observed with a polarizing microscope (100X);

[0026] The prescription of embodiment B and test result are shown in table 3 and figure 1 , it can be seen from the figure that the emulsion 669-058B has a lamellar liquid crystal structure, indicating that rapeseed oleamide propyl dimethylamine can be used as a liquid crystal emulsifier to prepare an emulsion with a lamellar liquid crystal structure, making the skin dry and non-sticky. It glides on smoothly and adheres very well to the skin, while providing powerful moisturizing benefits.

Abstract

The invention discloses an application of rape oleamidopropyl dimethylamine as an emulsifier in cosmetics. Compared with the prior art, the invention provides a new application of brassicamidopropyl dimethylamine in cosmetics, the brassicamidopropyl dimethylamine is high in emulsifying capacity, can be used for preparing an emulsion with a layered liquid crystal structure, can create an environment unsuitable for growth of microorganisms under an acidic condition, and one substance can play at least the two roles at the same time; in addition, the method is mild, natural, sustainable and biodegradable.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to the application of rape amidopropyl dimethylamine as an emulsifier in cosmetics. Background technique [0002] Brassicamidopropyl Dimethylamine is derived from rapeseed oil. It is mainly used as an excellent hair conditioner to antistatic, repair damaged hair, nourish hair and prevent hair frizz. [0003] For example, the patent application No. CN201510945249.4 (publication No. CN105380831A) patent "Silicon-free oil mild conditioning hair care composition and its preparation method" discloses a silicone-free oil mild conditioning hair care composition and its preparation method. The hair care composition comprises the following components in weight percentage: 2-7% of cationic conditioner, 1-4% of emulsifier, 2-10% of higher fatty alcohol, 1-10% of non-silicone oil or oil derivative %, additives 0.1-8%, water balance, wherein, the cationic conditioning agent is composed of beh...
