Definitions
- the present invention relates to compounds obtained by esterifying polyglycerin with fatty acids and dicarboxylic acids, solubilizers for poorly water-soluble substances containing the compounds, and cosmetics containing these.
- surfactants are used to solubilize poorly water-soluble substances such as fragrances and essential oils in aqueous solutions.
- poorly water-soluble substances such as fragrances and essential oils
- the use of naturally derived raw materials, solubilization with a small amount of surfactant, solubilization that does not require heating energy (cold process), and surfactants that satisfy high biodegradability are eco-friendly solubilization. It can be said that it is a drug.
- Polyglycerin fatty acid esters can be mentioned as materials for solubilizing poorly water-soluble substances.
- Polyglycerin produced by the ring-opening polymerization method of petroleum-derived glycerin derivatives and polyglycerin from which the low-polymerization degree is removed (Patent Document 1) are used to esterify with fatty acids to solubilize poorly soluble substances. A method is reported. However, a large amount of surfactant is required for poorly soluble substances, and further reduction of surfactant is required.
- An object of the present invention is to provide a novel compound that can solubilize fragrances and essential oils in small amounts.
- the present invention relates to the following [1] to [4].
- [1] A compound that is an ester of polyglycerol, fatty acid and dicarboxylic acid and satisfies the following (A) to (C).
- (A) The total proportion of unsaturated fatty acids with 18 to 22 carbon atoms and branched fatty acids in the total fatty acids is 48% by mass or more
- (B) The mass ratio of polyglycerin and fatty acids (polyglycerin:fatty acid) is 1:0.15 ⁇ 1:0.35
- C) the dicarboxylic acid has 4 to 12 carbon atoms, and the molar ratio to polyglycerin (dicarboxylic acid/polyglycerin) is 0.1 to 0.8
- a composition comprising the compound according to [1] and a polyglycerin fatty acid ester obtained by esterifying a fatty acid having 10 to 18 carbon atoms and polyglycerin.
- the present inventors newly found that by using polyglycerin and esters of specific fatty acids and dicarboxylic acids, fragrances and essential oils can be solubilized even in small amounts.
- the present inventors have newly found that the compound has a high solubilizing power even when a large amount of naturally-derived raw materials are used. Although the mechanism is unknown, it is presumed that cross-linking polyglycerin with dicarboxylic acid enhances the ability to form micelles and increases the solubilization region.

The present invention relates to compounds obtained by esterifying polyglycerin with fatty acids and dicarboxylic acids, solubilizers for poorly water-soluble substances containing the compounds, and cosmetics containing these.
化粧品分野において、香料や精油等の難水溶性物質を水溶液中に可溶化するため、界面活性剤が利用されている。近年、難水溶性物質を可溶化するだけでなく、環境にやさしい自然由来の界面活性剤が求められている。具体的には、自然由来原料の利用、少ない界面活性剤量での可溶化、加熱エネルギーを必要としない可溶化(コールドプロセス)、高い生分解性などを満たす界面活性剤が環境にやさしい可溶化剤といえる。
In the cosmetics field, surfactants are used to solubilize poorly water-soluble substances such as fragrances and essential oils in aqueous solutions. In recent years, there has been a demand for naturally derived surfactants that not only solubilize poorly water-soluble substances but are also environmentally friendly. Specifically, the use of naturally derived raw materials, solubilization with a small amount of surfactant, solubilization that does not require heating energy (cold process), and surfactants that satisfy high biodegradability are eco-friendly solubilization. It can be said that it is a drug.
難水溶性物質の可溶化素材として、ポリグリセリン脂肪酸エステルが挙げられる。今までに石油由来のグリセリン誘導体の開環重合法で製造されたポリグリセリンや、低重合度部分を除去したポリグリセリン(特許文献1)を用いて脂肪酸とエステル化し、難溶性物質を可溶化する方法が報告されている。しかし、難溶性物質に対して必要な界面活性剤量が多く、さらなる界面活性剤の低減が求められている。
Polyglycerin fatty acid esters can be mentioned as materials for solubilizing poorly water-soluble substances. Polyglycerin produced by the ring-opening polymerization method of petroleum-derived glycerin derivatives and polyglycerin from which the low-polymerization degree is removed (Patent Document 1) are used to esterify with fatty acids to solubilize poorly soluble substances. A method is reported. However, a large amount of surfactant is required for poorly soluble substances, and further reduction of surfactant is required.

The compositions of Examples 1, 15, and Comparative Example 4 and the components shown in Table 3 as poorly water-soluble substances were mixed at 50°C, and heated at room temperature (25°C) so that the content of the poorly water-soluble substances was 0.1% by mass. After adding to water and stirring for 10 minutes, the transmittance was measured with a spectrophotometer (manufactured by Shimadzu Corporation: UV-2600) at a wavelength of 650 nm. The amount (the amount of the composition of each example and comparative example in water) at which the transmittance becomes 98% or more was defined as the amount required for solubilization. Table 3 shows the results.
