Posted on August 11, 2019 by blogger

Is it necessary to use preservatives?

First, the use of preservatives in cosmetics primary role is to prevent the growth of microorganisms in the product, the nature of skin care products to maintain stability, and opening the lid after use non-perishable. The more water the more need for skin care products, preservatives, such as lotion, emulsion, ointment or wax while the closer, the bacteria more difficult to survive, relatively small demand for preservatives. In addition, the preservative products to reduce the raw material storage, Cosmetics material production, bottling products in the erosion potential of micro-bacteria is also beneficial.

2, preservatives, will stimulate the skin?

Unless there is a very sensitive skin or contact dermatitis condition, usually a small amount of preservative does not cause skin irritation, but does not rule out some manufacturers to extend product shelf life, and the use of the controversial preservative, such as benzene acid esters preservatives (many brands will promote healthy skin care specially marked “Parabens free benzoic acid esters do not add”). In addition, due to the complexity of the cosmetic product formulation, the active ingredient will need some special preservative, such as peptide class, unsaturated fatty acids, so you may find medical use for sensitive skin beauty products, astaxanthin usually a relatively simple formula, to reduce the amount of preservatives. Usually conditions, in order to ensure the safety of cosmetics, but also not have more than three kinds of preservatives added.

3, the skin damage caused by preservatives on what?

Excessive or inappropriate preservatives will make immature epidermal cells, loose, resulting in thinning of the epidermis, vulnerable to external stimuli, defense power drops; can damage cell DNA, the skin gradually loses its elasticity, easy to produce relaxation, fine lines ; but by the preservatives will continue to damage the skin cells reproduce defects, so that the skin is getting worse.

4, claiming that the product does not contain preservatives really no added?

Countries is not entirely uniform standard of preservatives, such as the EU cosmetics regulations promulgated Annex VI of isothiazolin-ketone are limited to the use of all within 15ppm; U.S. Cosmetic Ingredients Review (CIR) provides that in the washing products the maximum amount of 15ppm, while the maximum stay in the amount of product compared to 7.5ppm; in Japan provides isothiazolin-ketone can only be used in washing products. This also contributed to the same product in different national standards, which can be completely different degree of safety. Overall, preservatives, chemical preservatives, security, biotin non-toxic preservatives and natural organic preservatives (like preservatives) the difference between the European Union “cosmetic procedure” in Appendix VI covers five kinds of related preservatives (including hydroxy phenyl type preservative), and sometimes, many are not listed in the guide are also anti-microbial raw material role, known as the “class of preservatives” (such as some alcohols, and many essential oils and ethyl hexyl glycerin). As such Fancl preservative formulations used in the preservative is not in the state laws and regulations, minoxidil as no preservatives added. , But actually contain preservatives.

5, it may not add preservatives?

Usually take a small dose of the brand in aseptic packaging, can not use preservatives or use class formula, but in order to prevent air from entering, such products need to open the bottle within three days after you are finished; and vacuum pump against the return of packaging as to prevent air from entering, but also reduced the amount of preservatives. Avene brand recently launched a new “sterile space” concept, glutathione originally based on the vacuum nozzle to improve the original head of the “dead space” design, the nozzle always remains part of the original product, and back in use caused by pollution, The new design will not leave dead, to maintain product sterility during use.

6, how to reduce the damage of preservatives?

As mentioned above except for dermatitis or sensitive skin, in general, access to national security certification to add a small amount of preservative in cosmetics, skin will not cause excessive damage. However, the following two points to note: sensitive period in the skin, tretinoin try to choose products without preservatives or more single formula cosmetics, to reduce irritation caused by preservatives; like to mix and match cosmetics of women, try to choose the same brand, they usually choose the same preservative, preservative compound can be reduced to bring the stimulus.

7, homemade cosmetics, do not add preservatives are particularly safe?

Adding preservative to prevent not only the deterioration of the product in use or in order to reduce pollution in the production, packaging, health, and raw material contamination, the problem may be caused by deterioration, unless it is self-sterile plant, and to ensure zero pollution of raw materials, API supplier their own DIY cosmetics in the deployment process has to face many security risks, occasionally can be long-term use, it is more secure choice.

The Application Of Polyisobutylene In Cosmetics

Posted on August 2, 2019 by blogger

The application of polyisobutylene mainly focuses on cosmetic grade polyisobutylene, hydrogenated polyisobutene (synthetic squalane) and polyisobutylene triglyceride.
The straight-chain alkyl hydroxyl structure of cosmetic polyisobutylene and sebum is similar. So it is well compatible with the skin. Non-toxic, odorless, high purity, easy oxidation emulsification, moisture can form a water resistance film. The main application range of skin creams, lipsticks, make-up. At present, China’s application of cosmetics class polyisobutylene comes mainly from Japan, the United Kingdom.
Hydrogenated polyisobutene cosmetic features of the natural squalane, which is called synthetic squalane. At present, China’s application hydrogenated polyisobutylene comes mainly from the glutathione companies in Japan. Polysynlane is a colorless, odorless non-toxic high purity liquid heterogeneous straight-chain alkanes, cosmetics and pharmaceutical oil phase composition can be used without special restrictions; white mineral oil, petrolatum, Polysynlane give products to excellent noble touch, moisturizing and not greasy, moisturizing lubrication, the infiltration; very close to the nature of the natural squalane, but the minoxidil price is much cheaper; good thermal stability and storage stability, easy to use emulsion; irritation and allergic. The main indicators: the proportion (20 C) 0.822; refractive index (20 C) 1.457; Melting point / C a 50max; acid value 0.01max; saponification value 0.5max; iodine value of 0.2. According to the viscosity of different polysynlane divided into three levels of polysynlane, polysynlane LITE, Polysynlane4. The main application areas: lipstick can make a better pigment dispersion; cream coated with a sense of very good cream penetration, moisturizing, moisturizing without a greasy feel, bright, and can be used as a humectant, emollient. Herbal Aloe gel contains hydrogenated polyisobutylene (synthetic squalane) ingredients.
Polyisobutylene acid glycerides can be used as the main component of multi- functional wetting agent. It has highly efficient water lubrication. The node content is 33% ~ 58% and the free water content is about 5% ~ 22%. It can provide adequate moisture for sensitive and delicate mucous membranes in human body and human organs and maintain smooth. Moisturizing cream contains polyisobutylene triglyceride composition and polyisobutylene triglyceride. The polyisobutylene acid glycerides can be an effective treatment and eliminate vaginal dryness disease while alleviate and eliminate pain during intercourse caused by menopause and old age due to vaginal dryness. It maintains women’s normal physiological function and mental health.Source:http://www.cosprm.com

China’s Men’s Cosmetics Market Needs To Be Developed

Posted on July 8, 2018 by blogger

In the early of the reform and opening up, China’s cosmetics sales was 350 million. In 2006 China’s cosmetics sales exceeded 100 billion for the first time. Subsequently, the sales of cosmetics industry grow rapidly. In 2009 the sales were 400 times of that in 1980.

From the January to August in 2010, the sales value of China’s cosmetics industry reached 124.309 billion yuan, an increase of 23%. In 2009, China’s cosmetic sales value reached 150.52 billion yuan, an increase of 11.2%.

From the January to August in 2010, the total profits of China’s cosmetics industry reached 10.459 billion yuan, an increase of 9.1%. In 2009, the total profits of China’s cosmetics industry reached 15.495 yuan, an increase of 12.5%.

The per capita consumption level of Guangdong, Shanghai and Beijing is significantly higher than the national average level. While the per capita consumption level of cosmetics in developed countries is much higher. China’s cosmetics market has great room for growth. China has become the third largest cosmetics sales market only after the United States and Japan. The current kinds of men’s cosmetics are still relatively few. Few brands can truly win the customer’s trust. Few large brands have launched men’s grooming products.

But clearly this simple skin care products can not meet the requirements of many men. But foreign brands are too expensive and small domestic brand is too cheap. Therefore, the major domestic manufacturers have started to develop technology for beauty products that are needed by more men. They also began to introduce some foreign beauty equipment.

Now there are more and more professional beauty services for men. Men’s grooming items will be more detailed, professional, no longer just facial care and foot massage. It has been refined out tens to hundreds of different series of facial care, body care and foot care.

The requirements of some women on the beauty are often beauty and character, but basically most of the men were concerned about the actual quality of their skin, whether the perfume is suited to their temperament and how to do more to cover up their beauty weaknesses. So men are more practical. The effect is gradually revealed, so their beauty consumption is more lasting.

At present, male skin care market is like nursing infants. It is still in its infancy. Both the domestic and international brands have launched their own skin care products for men to seize the market. In the next few years, the market competition of the Chinese men’s skin care products will be more intense.

Common Antioxidants In Cosmetics

Posted on November 18, 2017 by blogger

With the age increasing, the body protection is decreased. Physiological damage caused by lipid peroxidation, especially reactions that endogenous superoxide free radicals in the body in the unsaturated fatty acids, resulting in unstable lipid peroxidation, and thus the decomposition of aldehydes, especially malondialdehyde aldehyde, which attacks phospholipids and proteins by the reaction to form lipid-protein complex, lipofuscin deposition in the cell, as a sign of cellular aging. Therefore, prevention and anti-oxidant has been a powerful tool for the treatment of skin aging, but also an important way for many other compounds to achieve anti-aging skin effect.
Are commonly used antioxidants include substances such as enzymes or enzymes of vitamin A, vitamin E, cysteine, ascorbic acid, superoxide dismutase, glutathione peroxidase, metallothionein, sulfhydryl papaya enzyme, coenzyme Q10 and so on. And some amino acids such as glycine, serine and salicylaldehyde with iron to form the condensation product 2: l complexes, inhibited by the reaction with hydroxyl radicals of iron-related, and can inhibit lipid peroxidation, also has anti- oxidation. Melatonin, estrogen and other hormones and is also related to reports.
Superoxide dismutase (SOD) is the most in-depth study of cosmetics, the most widely used anti-oxidants, contain copper, zinc, manganese and iron metalloenzyme, widely present in various tissues of organisms, is the only to specific antioxidant enzyme superoxide anion. SOD from cattle, pigs and other extracts of red blood cells, also from spinach, cabbage, prickly pear, yeast and bacterial extracts. Now know that at least Cu. SOD, Mn. SOD, Fe-SOD, Zn-SOD and EC-SOD in five different SOD. SOD activity of the enzyme used as a cosmetic ingredient as affected by many factors, such as short half-life in vivo residence time is short, usually only 6-20min: 32 000 molecular weight around easily through the stratum corneum and the cell membrane and has antigenic and so on. To address these negative factors, the major domestic use molecular engineering approach to heparin, polyethylene glycol, dextran, biotin and other water-soluble macromolecules to their non-active groups or the use of molecular modifications to increase its transdermal absorption of liposomes, etc. embedding the new carrier.
Vitamin E, C is the first cosmetic application of anti-oxidants, a natural antioxidant, and their main function is to reduce the damage of living cells with hydrogen peroxide, superoxide anion and hydroxyl generation. Main role: vitamin E can reduce eye burn of erythema, which may be due to removal of oxygen free radicals induced by UV radiation, the reason: vitamin C is unstable in aqueous solution, it is difficult to be absorbed through the skin. In a proprietary formula, vitamin C preparations added zinc and tyrosine (Cellex-C), topical, the vitamin C levels in the skin 20 times higher than normal, the depth of penetration into the dermis 500 U m, tretinoin from the anti- oxidation, can block ultraviolet UVA and UVB damage to the organization.
In addition, vitamin C is considered a cellular factor that can directly stimulate fibroblasts to produce collagen. Vitamin C is a necessary component of collagen metabolism. L-ascorbic acid-2-phosphate magnesium (VC-PMG) is another vitamin C preparations patented formula, which is more stable compounds have been used in Japan to pigmentation agent. In addition, the element germanium (Ge32) and certain herbal and marine extracts also has antioxidant effects reported.
