Description

The present invention relates to cosmetic compositions in the form of gels or oil-in-water emulsions and their use, as well as to methods for improving sensory properties by applying said cosmetic compositions onto the skin.

Skin needs moisturization to stay healthy. So far, moisturizing products have been the primary remedy. There are many moisturizing products in the cosmetic and personal care market, such as those described in patent applications WO2005/095462 and FR2902333. Skin moisturizing products can be classified into lotions, milks, creams, facial masks, essences, hydrators, and so on.

CN 110192999A contains 0.2%-0.5% water-in-oil dimyristyl phosphate emulsifier, 1%-2% oil-in-water PPG-10 cetyl ether phosphate, and 1%-1.5 acrylates/beheneth-25 methacrylate copolymer. %, in the form of O/W (oil-in-water). The make-up base can produce a refreshing feel and a moisturizing effect. However, said make-up bases are not very appealing to consumers due to their creamy appearance.

CN 109172386A contains the following components: 100-500 ppm oligopeptides, 1-10% purslane extract, 1-5% chamomile extract, 0.2-1% rhizoma acori tatarinowii volatile oil, 10-10% 30% glycerol polyacrylate, 1-5% propylene glycol, 1-5% glycerol, 0.1-0.5% p-hydroxyacetophenone, 0.1-0.5% octyl glycol, and the balance deionized A composite moisturizing hydrogel is disclosed that contains a weight percentage of water. This document mentions the use of polyacrylates in moisturizing products. However, the composite hydrogels have a high polymer content, which makes them feel greasy.

KR 20180102827A discloses hydrogel-type moisturizing cosmetic compositions prepared from hydrophilically modified lipid macromolecules with self-assembled gel properties. The composition contains 1-15% hydrophilically modified lipid polymer, based on the total weight of the composition. Said composition is capable of forming a strong protective skin film that facilitates percutaneous absorption of water-soluble or oil-soluble active ingredients. However, said compositions still have a high polymer content, which can cause a negative effect on skin feel.

Products such as those described in the above references are consistently unsatisfactory in several respects, such as moisture retention, refreshing feel, spreadability, appearance, and the like. Therefore, there remains a need to obtain improved cosmetic compositions that can overcome the above drawbacks and to develop methods for improving the sensory properties of applying cosmetic compositions onto the skin.

Phenonip XB Phenoxyethanol (and) Methylparaben (and) Ethylparaben (and) Propylparaben

The above raw materials are available from BASF SE.

The cosmetic compositions whose compositions are shown in Tables 1 and 2 were prepared as follows.

In a 200 ml beaker, emollients, co-emulsifiers and non-ionic emulsifiers and additional emulsifiers were added to form the oil phase (Blend 1), which was then heated to 80°C with stirring at 500 rpm. In another 300 ml beaker, water, solubilizer, humectant were added to form the aqueous phase (Blend 2), which was then heated to 80° C. with stirring at 1,500 rpm. Subsequently, the gel-forming (meth)acrylic polymer was placed in the water/oil phase (Tinovis GTC UP in the water phase and Cosmedia ACE, Cosmedia SP, and Luvigel EM in the other oil phase) at 1,500 rpm for 3 minutes. Disperse with stirring until uniform. The oil phase was then added into the water phase with stirring at 5,000 rpm for 8 minutes to obtain a homogeneous mixture, which was cooled to room temperature. Finally, pH modifiers and preservatives were added to the mixture.

The compositions in Tables 1-2 are based on the total weight of the composition.

During preparation, an amount of Lanette® O, or one of Tinovis® GTC-UP, Cosmedia® Ace, or Luvigel® EM in Comparative Examples 1-7 was added to the gel. It was found that the tissue functionality had to be increased compared to that of Examples 1-4 to the values shown in Table 1 in order to obtain it. If they were less than the values shown in Table 1, no gel morphology could be obtained.

2. Use Cases Prior to the start of the study, volunteers were allowed 5-10 minutes to habituate, depending on ambient conditions and/or mood. The tests were carried out in a room prepared according to DIN standard DIN Norm 10962 at a relative humidity of approximately 50% and a temperature of approximately 23°C. After toxicological clearance, volunteers (all Chinese women) tested samples on their forearms and scored "-1, -0.5, 0, 0.5, or 1."

1) Spreading 150 μL of sample in gel form was applied to the inside of the forearm. The applied sample was spread using 20 circular motions between the fingertips of the index and middle fingers. During this movement, volunteers were asked to rate which product on the forearm produced less resistance of the sample to movement. Less resistance means easier spreading.

A score of "-1" means that it is considerably difficult to spread compared to the reference example.
A score of "-0.5" means that it is difficult to spread compared to the reference example.
A score of "0" means equally spread compared to the reference example.
A score of "0.5" means that it spreads more easily than the reference example.
A score of "1" means that it is considerably easier to spread compared to the reference example.

2) Wateriness in Use Volunteers were asked to rate which product contained more water on the forearm during the first 10 circular spreads. More water means more watery feel in use.

A score of "-1" means that the wateriness in use is considerably less than that of the reference example.
A score of "-0.5" means less wateriness during use compared to the reference example.
A score of "0" means equivalent wateriness in use compared to the reference example.
A score of "0.5" means that there is more wateriness during use compared to the reference example.
A score of "1" means that there is considerably more wateriness during use than in the Reference Example.

3) Stickiness in Use Volunteers were asked to rate which product produced a heavier, oilier feel on the forearm during the first 10 circular spreads. A heavier oily feel means more stickiness in use.

A score of "-1" means that there is considerably more stickiness during use than in the reference example.
A score of "-0.5" means that there is much stickiness during use compared to the reference example.
A score of "0" means equivalent stickiness during use compared to the reference example.
A score of "0.5" means less stickiness during use compared to the reference example.
A score of "1" means that there is considerably less stickiness during use compared to the reference example.

4) Wax-like feel
150 μL of sample was spread until completely absorbed. Volunteers then pressed hard on the treated site with their index and middle fingers to feel a wax-like sensation that remained on their forearms, moving both fingers from top to bottom. Higher resistance means more wax-like feel.

A score of "-1" means that the wax-like feeling is considerably greater than that of the reference example.
A score of "-0.5" means that there is more wax-like feeling compared to the reference example.
A score of "0" means that the wax-like feeling is equivalent to that of the Reference Example.
A score of "0.5" means less wax-like feeling compared to the reference example.
A score of "1" means that the wax-like feeling is considerably less than that of the reference example.

Evaluation results are shown in Tables 3 and 4.

3. Result analysis

Tables 3 and 4 show the results from the inventive examples and comparative examples.

As can be seen from Table 3, by comparing Example 1 with Comparative Examples 1 and 6, Example 2 with Comparative Examples 2 and 4, Example 3 with Comparative Examples 3 and 5, and Example 4 with Comparative Example 7, Eumulgin Combining EO 33 with Eumulgin CO 40 reduces the amount of Lanette O or gel-forming (meth)acrylic polymer in the cosmetic composition. In addition, Examples 1-4 are better than Comparative Examples 1-7 in that they spread easily, are more watery in use, are less sticky in use, and/or have a less waxy feel. It is clear from Table 3 that there is

Table 4 shows evaluation results of some examples and comparative examples. With lower amounts of Eumulgin EO 33 and Eumulgin CO 40, the efficacy of the resulting composition is easier to spread, more watery in use, less sticky in use, and/or less waxy in feel. It can be seen that it will be good in terms of becoming.
