Description

  The present invention relates to a composition that can efficiently clean the skin while providing skin care benefits such as oil control, matting, brightness, and skin homogeneity.

  Foam cleaners are products that are commonly used for facial cleansing. However, in hot and humid emerging countries such as India, China and Indonesia, water is often a limited resource. On the other hand, consumers need to wash their face repeatedly to reduce sweat or clogged skin, as well as for religious practices.

  So far, pack-type facial cleansing compositions containing sebum absorbing powder, water repellent powder, nonionic surfactant and water have been known in the art (European Patent Application Publication No. 0282823). However, even though the drying characteristics are improved, it is cumbersome to wait each time until the pack-type composition is completely dry on the face. Furthermore, when such a type of composition is used, the remaining powder must be thoroughly rinsed with water. This is cumbersome and not particularly convenient in countries and regions where water is a limited resource.

  In addition, several cosmetic lotions containing polymer particles are also known in the art (US Pat. No. 4,294,823, EP-A-0998902). However, these cosmetic lotions do not have sufficient cleaning ability and matting effect.

  Therefore, it is an easy-to-carry gentle cleanser that does not require rinsing, as opposed to most cleaning products, especially to lighten the skin, impart a matte feel, and wash, especially in countries where access to running water is limited However, there is a strong need for cleaning agents that can be used multiple times during the day.

Evaluation of the protocol cleaning ability to evaluate the technical effect of the above composition (on the forearm)
1. Each composition was evaluated using a 2.5 × 2.5 cm ² square supplare (black leather).
2. To start the test, the baseline is measured directly on the bare skin using a hand-held colorimeter (eg spectrophotometer Konica Minolta CM-700d) to obtain the (L, a, b) coordinates of the bare skin. It was.
3. (Makeup) A 30mg foundation was placed on each sapula and spread evenly within the square. The measurement of (L, a, b) of {skin + foundation} was performed using a portable colorimeter, and the value before washing was obtained.
4. (Make-up removal) 1 gram of one of the compositions of Examples 1-5 or Comparative Examples 6-12 was applied to a cotton pad (eg, ALX, SAP code 531501020, Alexandre Cotton N). A cotton pad was then applied and rubbed against each spot while moving in a circle for 30 seconds.
5. Each set of {skin + foundation after washing} (L, a, b) was measured with a portable colorimeter after removing the foundation. Thereafter, the cleaning ability was evaluated as follows:
6. Detergency calculation: ΔE _max = maximum value corresponding to complete removal of makeup compared to bare skin

Where Δa ₁ = a bare skin-a {skin + foundation}
Δb ₁ = b bare skin-b {skin + foundation}
ΔL ₁ = L bare skin-L {skin + foundation}

For each equation, the ΔE _mean calculation was performed on two spots:

Where Δa ₂ = a washed skin -a {skin + foundation}
Δb ₂ = b cleaned skin -b {skin + foundation}
ΔL ₂ = L washed skin -L {skin + foundation}

  Finally, the cleaning capacity percentage (cleaning effect) was calculated by the following formula.

Evaluation of matte feeling imparting effect Each composition was spread in advance at room temperature on a sapla (skin model black leather) at a rate of ² mg / cm ² . The deposit is then dried at 37 ° C. for 60 minutes. By using a goniophotometer, graduation and light intensity measurements were performed on a matte standard plate made of barium sulfate and on a contrast card coated with a makeup base, respectively. Thereafter, the matte feeling imparting effect (R _gain ) is evaluated from the ratio R of regular reflection (measured at an angle of 30 °) and diffuse reflection (measured at an angle of 0 °). A low value of R means a high matte feeling imparting effect. If R is inferior to 2, there is no improvement in skin appearance.

  The results are shown in Table 2.

  The median particle size in the liquid environment was measured with Mastersizer 2000. Each particle was dispersed in the aqueous phase of the example.

  When Examples 2, 4 and 5 using silica particles were compared with Comparative Example 2, the matte feeling imparting effect (%) was over 40% in Examples 2, 4 and 5, whereas Comparative Example 2 The effect on is 38%. The cleaning effect is over 50% in Examples 2, 4 and 5, while the effect in Comparative Example 2 is 32%.

The cosmetic composition selected from Examples 1-5 shows a marked and superior effect in oil control, brightness, and skin homogeneity than the cosmetic composition selected from Comparative Examples 1-5.
