Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a composition with blackhead removing function and application thereof in cosmetics. Background Art

[0002] Blackheads are a common skin problem. They usually appear on the face, especially on the nose, forehead, chin and other T-zone areas where oil secretion is strong. The main reason for the formation of blackheads is that the oil secreted by the sebaceous glands in the pores mixes with dead skin cells and blocks the pore openings. When exposed to the air, they oxidize and turn black. Long-term accumulation of blackheads not only affects the beauty of the skin, but may also cause enlarged pores, rough skin and even inflammation.

[0003] There are many ways to treat blackheads on the market, including physical methods such as scrubbing and squeezing, chemical methods such as using exfoliating products containing ingredients such as fruit acid and salicylic acid, and physical removal methods such as facial masks and nose patches. However, these methods may be irritating or fail to fundamentally solve the problem, and some people cannot use them due to sensitive skin. Therefore, if you can use exfoliating products in combination with substances that can repair the skin barrier, you can speed up the recovery of the skin after removing blackheads.

[0015] Beneficial Effects The present invention provides a composition having a blackhead removing effect and application thereof in cosmetics. Compared with the prior art, the present invention has the following beneficial effects: 1. Mandelic acid and salicylic acid are added to the composition with blackhead removal effect of the present invention. Mandelic acid and salicylic acid can penetrate deep into the pores to dissolve oil and keratin, thereby reducing the formation of blackheads. Tea tree essential oil can remove bacteria and dirt in the pores. On the basis of removing blackheads, it can also be antibacterial and anti-inflammatory. However, mandelic acid, salicylic acid and tea tree essential oil are prone to cause skin allergies, and ingredients that can relieve skin allergies need to be added for neutralization. Adding carboxymethyl yeast glucan can reduce the tingling sensation of skin allergies and play a moisturizing role.

[0016] 2. The present invention extracts purslane by an ultrasound-assisted method to obtain a purslane extract. The purslane extract is rich in adrenaline, flavonoids, organic acids, cardiac glycosides and other substances, and also contains vitamins, minerals, amino acids and other ingredients. It has anti-inflammatory, anti-allergic and skin immune function enhancing effects. It is used in a composition with a blackhead removing effect to accelerate skin recovery. Secondly, the D-panthenol prepared in the present invention has the effect of quickly penetrating into the stratum corneum of the skin, can stimulate the growth of epidermal cells and thus accelerate the skin barrier repair after blackhead removal. Combined with the chitosan-based gel prepared based on chitosan, it can reduce the probability of skin irritation and allergy. Moreover, the chitosan-based gel has a loading effect and good film-forming properties, and can load mandelic acid, salicylic acid, tea tree essential oil, carboxymethyl yeast glucan, purslane extract and D-panthenol, and form a film on the skin surface to better achieve the effect of removing blackheads.
