Description

Atypical oil capsules, compositions containing the same, and methods for manufacturing the same {ATYPICAL OIL CAPSULES, COMPOSITION COMPRISING THE SAME AND METHOD FOR MANUFACTURING THE SAME}

Disclosed herein are amorphous oil capsules, compositions containing the same, and methods for producing the same.

Many types of fat-soluble active ingredients are widely used in cosmetics due to their excellent effects such as wrinkle improvement, moisturizing enhancement, antioxidant, etc. However, they easily cause discoloration and/or off-odor due to external environments such as air or moisture, and their potency is reduced, reducing their efficacy. There is a problem of deterioration. For example, fat-soluble active ingredients such as retinol and retinol derivatives have excellent anti-wrinkle efficacy, but their use is extremely limited due to their unstable properties that are easily destroyed by light, heat, air, and moisture.

To stabilize such retinol and retinol derivatives, stabilization technology using antioxidants, physical adsorption technology using porous silica or phospholipids, stabilization technology using capsule wall materials using polymer polymerization, and emulsion stabilization using one or more lyotropic liquid crystals. Technologies have been developed.

However, although these conventional stabilization technologies have improved the stability of retinol and retinol derivatives to some extent, they have not yet reached a satisfactory level for stable and universal use in various cosmetic formulations. For example, in terms of stability, the blocking of oxygen, ultraviolet rays, and moisture, which affect the acceleration of oxidation of retinol and retinol derivatives, is not satisfactory, and excessive use of antioxidants has the problem of causing toxicity such as skin irritation. . In addition, in the case of technology using a cross-linked capsule wall material, even if stability is improved, the active ingredients inside the capsule cannot leak out of the capsule wall material, so the efficacy on the skin is often not fully achieved.

As a result, the cosmetics of Examples 1 to 4 achieved a stable capsule formulation by trapping fat-soluble active ingredients in oil capsules. The oil phase was dispersed in the water phase and then cooled to further harden the oil phase. Then, homomixing was performed at low speed to split the hardened oil phase into irregular pieces to prepare irregular oil capsules with a unique appearance. The manufactured capsule formulation showed long-term stability without breaking or discoloring despite changes in time and temperature, and showed an excellent feeling of use with no foreign body sensation and smooth application. In addition, according to Example 2, the content of phytosphingosine and hydroxypropyl bispalmitamide MA, which are oil-soluble active ingredients previously applied only to emulsified products, can be increased to 0.05% by weight each in a capsule-containing formulation with a transparent appearance. It was confirmed that it was possible.

As a result, the cosmetics of Comparative Examples 1 to 4 formed a spherical oil capsule formulation, which is not amorphous but has a typical oil capsule shape. The cosmetic of Comparative Example 2, in which the oil thickener content was increased to 33.3% by weight of the oil phase, had a feeling of foreign body in the capsule when discharging the contents, resulting in a poor feeling of use, and the cosmetic of Comparative Example 3 in which the oil thickener content was reduced to 5.9% by weight of the oil phase The capsule size decreased. The cosmetic of Comparative Example 4 had the oil-soluble active ingredient content increased to 18.1% by weight of the oil phase, and the hardening degree of the oil portion was very low, so not only did the capsule size decrease, but the capsule was discolored, resulting in poor stability over time.

Comparative Examples 5 to 6.

A cosmetic containing oil capsules was prepared according to the method described in Example 1, and a cosmetic containing oil capsules of Comparative Example 5 was prepared by adding the oil phase at 80 °C to the water phase at 46 to 56 °C.

In addition, a cosmetic containing oil capsules was prepared according to the method described in Example 1, and a cosmetic containing oil capsules of Comparative Example 6 was prepared by adding the oil phase at 80 ° C to the water phase at 24 to 34 ° C.

As a result, if the temperature of the water phase exceeded 45 ℃, not only did the capsule size become smaller, but also an irregular capsule shape could not be realized. If the temperature of the water phase was less than 35 ℃, the oil phase at 80 ℃ hardened immediately on the surface and agglomerated together, causing dispersion. It was difficult and difficult to form a capsule formulation.
