Description

Cleaning composition {CLEANSING COMPOSITIONS}

The present invention relates to cleaning compositions. In particular, it relates to a mild body cleansing composition that exhibits improved deposition of skin care actives such as antibacterial agents, sunscreens and vitamins. In addition, the compositions of the present invention exhibit improved rinsing feeling and foaming properties with good skin feel properties, and are suitable for simultaneously cleaning and conditioning skin and / or hair, for example in a foam bath. ), Shower products, skin cleansers, hand, face and body cleansers, shampoos and the like.

Mild cosmetic compositions should meet a number of criteria including skin cleansing, foaming properties, and mild / low irritant / good feeling for the skin, hair, and eye mucous membranes. The skin is made up of several layers of cells that cover and protect the underlying tissue. Keratin and collagen fiber proteins form the backbone of its structure. The outermost layer of these layers is referred to as the stratum corneum. Similarly, hair has a protective outer coating that encloses hair fibers called cuticles. Anionic surfactants can penetrate the stratum corneum membranes and cuticles and can destroy membrane integrity and impair barrier membrane and water retention functions by degreasing. Such interference with the skin and hair protection film can roughen the skin and irritate the eyes, eventually causing the surfactant to trigger an immune response creating irritation.

An ideal cosmetic cleanser should gently clean the skin or hair without degreasing and / or drying the hair and skin, and without irritating the eye mucosa or pulling the skin after frequent use. Most foaming soaps, shower and bath products, shampoos and bars do not meet this aspect.

Some synthetic surfactants are known to be mild. However, the main drawback of some mild synthetic surfactant systems when formulated for shampoo or body cleansing is the "slippy" or "non-draggy" rinse feel that some users do not like. It has a feeling that can be described. On the other hand, with some surfactants, such as potassium laurate, a "stripping" rinse feel can be obtained, but clinical skin mildness is lost. Both of these facts make the selection of a suitable surfactant in the formulation process with the advantages of rinsing feel and mildness a precise balancing task.

Thus, in addition to good product properties such as foam, cleansing, stability, thickening, rheology and skin feel properties in use, there is a need for a body cleansing composition that delivers a “grabbing” rinse feel and at the same time provides good skin softness.

It is also desirable to deliver skin active ingredients from the body cleansing composition to the skin. Such skin active ingredients include, for example, sunscreens, antibacterial agents and vitamins. Attempts have been made in the past to deliver skin care actives from body cleansing compositions. However, they have not always been successful in terms of depositing these active ingredients sufficiently on the skin to be effective.

WO 97/16168 discloses a body cleansing composition comprising (a) a hydrophobic active ingredient selected from surfactants, (b) skin conditioning agents, skin protectants and antibacterial agents, (c) hydrocarbon containing ingredients and (d) cationic polymers. In the present disclosure, the amounts of (c) and (d) are selected such that the effect on the skin by component (b) is improved beyond the addition effect of (c) and (d) alone.

Surprisingly, the body cleansing composition, which improves the deposition of hydrophobic skin care actives and at the same time has a rinsing rinsing feeling and excellent mildness properties, has a specific water-insoluble oil such as certain polyalphaolefin oils and certain hydrophobic skin activity with a mild water-soluble surfactant system. It has now been found that it is provided by a combination of ingredients.

[Overview of invention]

According to the present invention there is provided a rinse-free liquid body cleansing composition comprising:

(a) water,

(b) about 1% to about 60% by weight of a water soluble surfactant,

(c) a water insoluble oil selected from a highly branched polyalphaolefin of the formula: having a number average molecular weight of about 1000 to about 25,000:

[Wherein, R ¹ is H or C ₁ -C ₂₀ alkyl, R ⁴ is C ₁ -C ₂₀ alkyl, R ² is H or C ₁ -C ₂₀ , R ³ is C ₃ -C ₂₀ , preferably Preferably C ₅ -C ₂₀ , n is an integer from 0 to 3, m is an integer from 1 to 1000; and

(d) a hydrophobic skin active ingredient selected from antibacterial agents, sunscreens, vitamins, perfume oils, insect repellents, antifungal agents, and mixtures thereof, having a ClogP value of at least 3.

The composition of the present invention improves the deposition of the skin active ingredients and at the same time provides an exceptionally mild and “stripping” rinse feel to the skin.

All concentrations and ratios herein are by weight of the cleaning composition unless otherwise indicated. Surfactant chain lengths are also by weight average chain length unless otherwise indicated.

Liquid cleaning compositions here consist of water, surfactants, hydrophobic skin active ingredients and water insoluble oils, which are described below.

As used herein, the term “rinse feeling” means the feeling of the skin during the process of rinsing the foam from the skin after washing with the cleaning composition. The type of rinsing feeling provided by the composition of the present invention is expressed in terms such as a "grabbing" rinse feeling, a "soapy" rinse feeling and a "non-slip" or "non-sticky" rinse feeling. Such a "floppy", "soapy", "non-slip" or "non-sticky" rinse feeling can be perceived as an increase in friction between the hand and the skin during the process of rinsing foam from the skin.

As used herein, the term "water insoluble" refers to a material that is substantially insoluble in distilled water at room temperature without the addition of other auxiliaries and / or components as described herein.

As used herein, the term "hydrophobic" with respect to the skin active ingredient means a substance that is more fat-soluble than water-soluble, ie, water-insoluble. The material is preferably insoluble in water and essentially nonionic, a property opposite to ionicity.

Manufacturing method

The composition can be prepared by first making a premix of a portion of the surfactant, suspending agent and thickener. This preliminary mixture contains 50-70% by weight of the total composition of the surfactant and contains both lauroampoacetate. This is accomplished by blending the surfactant (except sarcosinate), an appropriate amount of water, a powder preservative and a pH adjuster with gentle shaking. The mixture is then heated to about 90 ° C., with the suspending agent being added while shaking.

The mixture is held at high temperature for a few minutes and then cooled through a heat exchanger at a controlled rate to allow the suspending agent to crystallize.

The remaining water is added to the premix followed by the remaining amount of surfactant, preservative, flavoring, sodium chloride and hydrophobic skin active ingredient. High shear mixing will be required for some hydrophobic skin actives. Finally, water insoluble oil is added. This part of the process is carried out at room temperature with gentle shaking to obtain the desired average droplet size of 5 to 20 microns.

The product not only has excellent deposition of skin care actives, excellent rinsing and mildness, but also excellent fluidity properties during storage, dispensing and use and excellent efficacy including skin conditioning, skin moisturizing, good product stability, cleansing and foaming To provide.
