9 b) The Present Application is a PCT international continuation of my pending US non-provisional Patent Application Serial No. 12/475,719 filed on 1 ii June 2009, which is incorporated by reference in its entirety herein. The 12 Present Application claims the benefit of and priority to said US non-13 provisional patent application.
The Present Invention relates to the field of protective compositions to 16 condition dry, cracked, and chapped skin so as to retain moisture, and to 17 condition hair.
19 There is currently a wide variety of moisturizing skin softeners on the market. The primary purpose of such products is to prevent moisture from 21 escaping from the skin while adding moisture to the skin. The vast majority of 22 these commercial products are oil based, or they utilize an oil-water emulsion.
23 The effect of these oil based products is to coat the skin with a layer that is 24 water impermeable. This water impermeable layer prevents the skin from losing water due to evaporation. Most of these preparations use various 26 additives that treat skin to make it smooth, moist, and supple. Yet, the skin 27 cannot breathe through this impermeable layer. This represents a problem in 28 that oxygen must be absorbed through the skin to sustain life.
29 Better moisturizing skin conditioners are water based, but these are in the minority. They employ moisturizing and conditioning agents to treat dry 31 and damaged skin. Some of them utilize a very small amount of cationic 32 agent in order to minimize the electrostatic effect of using these products.
33 Cationic additives are normally not used in oil based preparations. Unlike oil 1 based preparations that work by placing a protective layer over the skin, water 2 based preparations work by reducing skin tension.
3 If the air is very dry, a person moving through air will accumulate 4 negatively charged electrons on his skin due to air/skin friction. Should enough electrons accumulate on the skin, a person's hair will "stand on end."
6 Having a "like" electrical static charge, the hairs repel each other. Skin cells 7 exhibit a similar phenomenon. For example, "cracking" of the skin results 8 from dry skin cells "standing on end," and repelling one another. Dry, 9 chapped, or broken skin is due to a repulsive force between the cells. This io produces skin tension. The condition is aggravated by a lack of moisture.
ii The pores open, and moisture escapes. Rubbing one's hands together also 12 creates an electrostatic charge that makes the skin dry and chapped. The 13 skin has accumulated an excess of electrons.
14 Hair conditioners work in a different way. When a person wets his or her hair, the hair tends to "go limp" because water is a plasticizing agent for 16 hair. Hair conditioners enhance the plasticizing effect. In addition, they add 17 ingredients to treat hair to make it less brittle.
19 The Present Invention is an aqueous preparation that comprises cationic agents to neutralize a negative charge thereby relieving tension in the 21 skin, allowing the pores to close, and preventing moisture from escaping.
It 22 reduces the distance between the pores. The difference between the Present 23 Invention and other water based skin conditioners is the amount of cationic 24 agents used. The Present Invention utilizes much more of these ingredients than other commercial products. This produces the unexpected result of 26 neutralizing the charge on the skin and relieving tension. In its most basic 27 form, it contains no moisturizing or other skin conditioning agents. These 28 products can be added to the Present Invention, or alternatively, the Present 29 Invention may be used as an additive to commercial water based skin softeners.
2 A typical formulation of the product of the Present Invention might 3 consist of:
4 Celquat SC-240c (Polyquaternium-10) 0-4%
Merquat 100 0-11%
6 as the principal ingredients (cationic agents) and:
7 = Distilled Water 8 = Propylene Glycol 9 = Tetrasodium EDTA
= Polywax 11 = Glycerol Monostearate (Glyceryl Stearate) 12 = Vanilla 13 = Glycerin 14 = Germall Plus (Diazolidinyl Urea & Isopropynyl Butylcarbamate) This formulation is typical. Merquat 280 is Polyquaternium-22. Celquat 16 and Merquat are both strong cationic agents. The formulations created thus 17 far comprised both Celquat and Merquat. However, it could be useful to have 18 either agent be the sole active ingredient.
19 Cationic agents other than Celquat and Merquat are known in the art.
These other agents are also useful in the Present Invention either as a 21 substitute for Celquat and Merquat or as an additive. As mentioned before, 22 only water based products can utilize cationic agents. The difference between 23 the Present Invention and other commercial conditioners is the strength of the 24 cationic effect. This produces the unexpected result of neutralizing the negative charge of the skin, thereby reducing skin tension (by allowing the 26 skin cells to reside closer to each other), and closing pores so as to retain 27 moisture.
28 The basic formulation mainly comprises the cationic agents in an 29 aqueous base. However, moisturizing and conditioning agents can be added to the basic formulation. On the other hand, the basic formulation may be 31 added to other water based skin conditioners to enhance their effect.
32 The Present Invention may be used as a treatment for psoriasis which 33 is aggravated by dry skin. It may also be used to treat chafed elbows. In 34 addition, when added to hair conditioners, it enhances the plasticizing effect by neutralizing any negative charge retained by the hair.
36 Other formulations comprise the following ingredients:
1 = Water 2 = Cetyl Alcohol 3 = Cetrimonium Chloride 4 = Polyquaternium - 67 = Glyceryl Stearate 6 = PEG - 100 Stearate 7 = Polyquaternium - 22 8 = Phenoxyethanol 9 = Stearyl Alcohol = Benzalkonium Chloride 11 = Hydroxypropyl Trimonium Hydrolyzed Soy 12 = Methylparaben 13 = Propylparaben 14 = Butylparaben = Ethylparaben 16 = Isobutylparaben 17 = Sodium Hydroxide 18 = Hydrolyzed Algin 19 = Chlorella Vulgaris Extract = Sea Water 21 = Propylene Glycol 22 = Euterpe Oleracea (Acai) Fruit Extract 23 = Lycium Barbarum (Goji Berry) Fruit Extract 24 = Punica Granatum (Pomegranate) Extract = Diospyros Kaki (Persimmon) Fruit Extract 26 = Fragrance 28 Yet, other formulations comprise:
29 = Water = Isocetyl Behenate 31 = Cetyl Alcohol 32 = Cetrimonium Chloride 33 = Polyquaternium - 67 34 = Glyceryl Stearate = PEG - 100 Stearate 36 = Polyquaternium - 22 37 = Phenoxyethanol 38 = Stearyl Alcohol 39 = Benzalkonium Chloride = Hydroxypropyl Trimonium Hydrolyzed Soy 41 = Methylparaben 42 = Propylparaben 43 = Butylparaben 44 = Ethylparaben = Isobutylparaben 46 = Sodium Hydroxide 47 = Propylene Glycol 1 = Symphytum Officinale (Comfrey) Leaf Extract 2 = Centaurea Cyanus (Cornflower) Flower Extract 3 = Echinacea Angustifolia Leaf Extract 4 = Silybum Marianum (Milk Thistle) Extract = Fragrance 7 The formulations that follow comprise these generic ingredients:
8 = water (used as a solvent and moisturizer);
9 = at least one quaternary conditioner;
= at least one preservative;
11 = at least one thickener;
12 = an emollient;
13 = an emulsifier; and 14 = a neutralizing agent to adjust pH as desired.
The above formulation has an aqueous base, but one skilled in the art 16 would know that the formulation may also be non-aqueous. In addition, some 17 embodiments comprise an antiseptic, an anti-inflammatory agent, an 18 antioxidant, an astringent, and an agent to promote skin healing, having 19 cleansing, antibacterial and antiseptic attributes. Also, a fragrance would probably be added.
21 The quaternary conditioners that are used include (at least one must 22 be used), without limitation:
23 = Polyquaternium-22;
24 = Polyquaternium-67;
= Cetyl Trimethyl Ammonium Chloride;
26 = Hydroxypropyl Trimonium Hydrolyzed Soy Protein; and 27 = Benzalkonium Chloride.
28 The preservatives used include, without limitation:
29 = Phenoxyethanol.
= Methyloaraben, 31 = Butylparben, 32 = Ethylparaben, 33 = Propylparaben, 34 = Isobutylpareben, and
5 1 = Phenoxyethanol.
2 The thickeners used include, without limitation, Cetyl Alcohol, and 3 Stearyl Alcohol. The emollients used include, without limitation:
4 = Isocetyl Behanate, = Water,
6 = Hydrolyzed Algin,
7 = Chlorella Vulgaris, and
8 = C10-30 Cholesterol/ Lanosterol Esters.
9 The emulsifiers used include, without limitation, Glyceryl Stearate, and to PEG-100 Stearate. The neutralizing agent used was a 5% solution of sodium 11 hydroxide. Fragrances used were lavender, sandalwood, and honeysuckle.
