Description

The present invention relates to W/O emulsion compositions, in particular sun care compositions in the form of W/O emulsions, for keratinous materials such as skin.

Sun care products are widely used to protect keratinous substances, especially the skin, from damage caused by UV radiation. Among sun care products, W/O emulsion sun care compositions are widely marketed as they are generally water resistant and thus can be retained on the surface of the skin even after exposure to water or perspiration.

For example, JP-A-2009-191033 discloses (A) organopolysiloxanes modified with partially crosslinked polyesters; (B) particulate zinc oxide and/or organotitanate treated with organotitanates; (C) silicone oil; (D) one or more oily agents selected from glyceryl trioctanoate, tri(caprylic-capric)glyceryl, and neopentyl dioctanoate. , discloses water-in-oil type sunscreen cosmetics.

In recent years, pollution of the marine environment and destruction of marine ecosystems by microplastics has become a serious concern. Therefore, cosmetics containing only small amounts of microplastic fillers or cosmetics containing no microplastic fillers have been proposed.

For example, JP-A-2020-97552 describes the following components (a)-(d): (a) 6-10 wt% hydrophobic fumed silica; (b) 5-20 wt% octamethyltrisiloxane and/or or decamethyltetrasiloxane; (c) batyl alcohol; and (d) 10 to 30 wt% of a powder other than (a) containing no microplastic beads to compensate for irregularities (microplastic beads Cosmetics for compensating for unevenness).

In sun care cosmetics, organic UV screening agents are widely used to impart UV protective properties to sun care compositions. However, the use of organic UV-screening agents can have adverse effects such as imparting an oily, greasy and sticky feeling during application. Also, oil in W/O emulsions can cause a feeling of oiliness, greasy and stickiness upon application. Furthermore, there is the problem that W/O emulsions may lack sufficient stability to maintain their emulsion morphology over time.

Therefore, there is a need for a W/O emulsion composition containing an organic UV-screening agent that is highly water-resistant, imparts improved texture such as a fresh feeling, and has good stability without causing phase separation over time. It is Additionally, sun care cosmetic compositions that do not contain microplastic fillers are also desirable as environmentally sustainable products.

Subsequently, the hand was placed in a beaker containing 2 L of tap water for 1 minute, after which the change in skin color was visually observed. The change in skin color for each composition was evaluated according to the following criteria.
1: No change in skin color was observed.
2: A slight change in skin color was observed.
3: A moderate change in skin color was observed.
4: A clear change in skin color was observed.

- Water clarity After applying 1 g of each composition to the back of the hand, the composition was allowed to dry for 1-2 minutes. Subsequently, the hand was placed in a beaker containing 2 L of tap water for 1 minute, and then the change in water surface was visually observed.

30 mg of each composition was applied with a finger to and around a 30 mm x 30 mm area of the panelists' forearms (n=5). The fresh feeling for each composition was evaluated according to the following criteria.
1: juicy and fresh
4: Greasy

(Stability)
100 mL of the resulting emulsion composition was kept at 25° C. for 24 hours after preparation. The appearance of each sample was then observed with the naked eye. The stability of each composition was evaluated according to the following criteria.

Compositions according to Comparative Examples 2 and 3, which did not contain any cationic polymer, did not exhibit good water resistance and exhibited poor W/O emulsion stability. The compositions according to Comparative Examples 4-6, which contained large amounts of microplastic fillers, exhibited poor water resistance due to poor water clarity results.

It can therefore be concluded that the W/O emulsion composition according to the present invention is highly preferred as a sun care cosmetic composition.
