Technical Field

The invention relates to the technical field of depilatories, in particular to a depilatory cream and a preparation method thereof.

Background

Epilation methods are generally divided into three categories: mechanical depilation method, chemical depilation method and physical depilation method. The chemical depilation method comprises applying depilatory cream etc. on local skin, so that hair shaft can be corroded and dissolved to rapidly achieve depilation effect, and hair growth speed is slow, and the effect can last for more than 2 weeks.

The depilatory creams which are used for human body depilation in the market at present contain calcium thioglycolate, have great pungent smell, are very uncomfortable to smell, and are easy to damage the skin when in use, thereby causing the symptoms of folliculitis, redness, itching, pain and the like of the skin.

Therefore, there is a need to develop a safe, odorless depilatory cream.

(2) adding each component in the mixture B into an emulsifying pot, reserving 15% of component water, heating to 80-85 ℃, and homogenizing and dispersing uniformly; then pumping the mixture A mixed in the previous step, homogenizing for 10min, keeping the temperature and stirring for 15 min, and then cooling;

(3) cooling to 60-65 ℃, adding each component of the mixture C, and uniformly stirring;

(4) cooling to 42-45 ℃, adding the component D pre-dissolved by 15% of water reserved in the step (2), and uniformly stirring;

(5) and filtering and discharging after the inspection is qualified.

Preferably, the frequency of stirring in steps (1), (3) and (4) is 600 r/min.

Preferably, the frequency of stirring in step (2) is 850 r/min.

Preferably, the frequency of homogenization in step (2) is 18-20 Hz.

Preferably, 200-mesh double-layer filter cloth is adopted for filtering in the step (5).

Compared with the prior art, the invention has the following beneficial effects:

the calcium thioglycolate in the formula is used as a reducing agent to destroy disulfide bonds in hair protein so as to achieve the purpose of lightening or dissolving hair, thereby achieving the hair removal effect. The nanometer activated carbon and the calcium thioglycollate can effectively adsorb the taste of the calcium thioglycollate, and the essence in the formula ensures that the preparation is safe and odorless, and has good olfactory experience in the use process of a user.

The glycerin and the betaine in the formula are used as the humectant, the mineral oil and the ethylhexyl palmitate are used as the emollient, and the combination of the glycerin and the betaine in the formula ensures that the depilatory cream has the effects of moistening and protecting the skin, has no stimulation and damage to the skin when in use, and does not cause the symptoms of folliculitis, redness, itching, pain and the like of the skin.
